GENERAL REGULATIONS This Safety Manual provides specific information for staff and students working in the Biology and Chemistry laboratory areas within the Fogg and Joseph Priestley buildings. It provides a written record of the customary procedures and a reminder of safety issues of particular relevance to those working in biology laboratories. Staff and students should familiarise themselves with the College’s Environmental Health and Safety Web pages at http://qm-web.safety.qmul.ac.uk/index.html These provide details of college policies and procedures, safety courses and links to other useful sites. The School safety website also has the Biology Division Safety Manual, Chemistry Division Safety Manual and Field Study Manual. As well as this document, these provide a written record of departmental procedures and a reminder of safety issues of particular relevance to work in the divisions and the School overall. Copies of this manual are available for view or downloading at http://www.sbcs.qmul.ac.uk/students/healthandsafety/index.html 2. SAFETY INDUCTION All new members of staff, research workers and visitors will receive appropriate safety inductions, which will consist of laboratory, office and fire safety inductions, or other training deemed appropriate, a record of induction will be kept. 3. TRAINING RECORD All staff will have a training record. The record will detail all training procedures that have been completed; the record will be kept with the safety co-ordinator and removed when the individual has left the School. 4. MANDATORY TRAINING As part of induction and local rules within the School, the following training courses are deemed mandatory, Fire Safety Interactive, Display Screen Interactive, COSHH and/or BIOCOSHH (where appropriate). These courses and how to access them will be covered in the Safety Induction or details can be obtained from SBCS safety Coordinator. 5. MANDATORY TRAINING FOR TEACHING LABORATORIES All staff running or involved in demonstrating during practicals must have undergone COSHH and/or BIOCOSHH training or they will not be allowed to oversee the laboratory practical. Undergraduates are deemed to be undergoing safety training as part of their education in the University. 6. EMERGENCY PROCEDURES IN EMERGENCY DIAL 3333 College Security will set up a conference call to the emergency services and listen in while you Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 3 report the emergency, and will also summon College staff to your assistance. 7. ACCIDENTS and REPORTING All accidents, no matter how minor, must be reported to both the School Safety co-ordinator or designated deputy and sent to OHSD (occupational Health and Safety Directorate). The form is available electronically from SBCS safety website or from OHSD website, hard copy can be found in the teaching laboratories. http://qm-web.safety.qmul.ac.uk/index.html The completed form must be returned to: College Health and Safety Office d.ford@qmul.ac.uk Tel: 13 5701 A copy must also be returned to: School Safety Co-ordinator a.j.philcox@qmul.ac.uk Tel: 13 6339 If the accident is such that treatment is given by the Health Centre or a casualty department, the form must be completed upon return to the School with copies distributed as advised above. Please note the following: The Health and Safety at Work, etc. Act 1974, updated 1992, requires that certain accidents and dangerous occurrences must be reported to the Health and Safety Executive within seven days of the incident. Failure to do so is a criminal offence. Appendix 1 summarises those accidents and dangerous occurrences that must be reported to the Health and Safety Executive. The full list of reportable accidents and dangerous occurrences is contained in the Reporting of Incidents, Diseases and Dangerous Occurrences Regulations 1995 (RIDDOR). The OHSD is responsible for reporting accidents or dangerous occurrences in the correct manner and it is therefore essential that they are notified as quickly as possible after the accident. When a reportable accident or dangerous occurrence has occurred, the site of the incident (other than for purposes of making the area safe) must not be cleaned, tidied up, or in any other way disturbed until both the College and Safety Advisers have conducted an initial investigation. 8. FIRST AID and MEDICAL TREATMENT The appropriate course of action to take in the event of an accident will depend on the nature of the injuries sustained. In a medical emergency, dial 3333; you can also call (9)999. Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 4 Tell the operator that you are calling from the School of Biological and Chemical Sciences (Mile End campus) and give your exact location. Queen Mary, University of London School Biological and Chemical Sciences Fogg Building Bancroft Road London, E1 4NS Queen Mary, University of London School Biological and Chemical Sciences Joseph Priestley Building Westfield way London, E1 4NS Queen Mary, University of London Bancroft building Library square London, E1 4NS. There is an emergency telephone at the 3rd floor general office Fogg building, Joseph Priestley 1st floor Stores, or the porters’ desk on the ground floor of the Bancroft building foyer. Follow the dialling instructions displayed above the phone and ask for an ambulance. Emergency medical treatment may also be obtained at: The Accident & Emergency (A&E) department of the Royal London Hospital Whitechapel, London E1. (2 Km westwards along the Mile End Road) Because the route to the Medical Centre can involve negotiating stairs, steps and Bancroft Road, anyone going for treatment should be accompanied in order to guard against possible further accidental injury. Minor injuries Minor injuries can be treated using materials from the First Aid boxes which are located in teaching laboratories and the larger research laboratories in both the Fogg and Joseph Priestley Buildings, and in the research laboratories in the Bancroft buildings. The Fogg Building 3rd floor Reception and the Joseph Priestley 1st floor Stores also have first aid boxes. A list of current First Aiders in the Fogg building is displayed on each floor. In the Joseph Priestley building they are displayed on notices in Stores and elsewhere. First aider lists are displayed in the Bancroft building. Contact security if in doubt. Non life-threatening accidents may be dealt with at: Queen Mary Occupational Health department. Ground Floor, Geography Building Telephone - 020 7601 7825 (15 7825 internal) 0830-1600 Monday to Friday Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 5 9. FIRE SAFETY The Queen Mary Health & Safety Department officials: Dennis Browne ext 13 8380 email: d.browne@qmul.ac.uk Keith Vagg ext 13 8384 email: k.vagg@qmul.ac.uk These individuals can be contacted for advice on fire safety procedures, fire safety risk assessment or training. If a fire breaks out in your presence: Raise the alarm by breaking the glass on the nearest fire alarm point. If a fire has taken hold, leave immediately. Small fires should be put out immediately using the appropriate extinguisher, fire blanket or sand bucket but if it is safe to do so. Do not take any personal risk. You should make yourself familiar with the locations of fire alarms, extinguishers, fire blankets and the various fire exits from the building. In the Fogg Building there are alarms in the lift lobby area. In the Joseph Priestly Building there are alarms in the main corridor next to the research laboratory entries and also on the back (South) staircase, as is the case in Bancroft Report any use of the extinguishers, other equipment or discharge to the Safety coordinator or through Estates Helpdesk. Estates-helpdesk@qmul.ac.uk Ext 2580 This will ensure that OHSD will replace the extinguisher immediately after use. When you hear the fire alarm: On hearing the fire alarm, leave the building by the nearest route. Behave calmly: do not run, do not take risks, use the stairs. Do not use the lifts. If you are in a lift when the alarm sounds, leave it at the next floor and descend via the stairs. The "means of escape" routes within the Building are clearly marked with EXIT or FIRE EXIT signs. Please familiarise yourself with all escape routes in the building. If you find your nearest escape route blocked, follow the EXIT or FIRE EXIT signs in an alternative direction to find a staircase by which you can descend. All staircases descend directly and provide egress from the building at ground level. If it is safe to do so, turn off your apparatus, close the windows and doors - do not lock the doors - and leave the building by the stairs. If possible, notify the fire marshal, who should be on the door organising the egress from the building, he/she will then inform the fire brigade of the location of the fire. Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 6 If you believe anyone has been left in the building, inform the fire marshal or fire brigade when they arrive. If the fire alarm sounds in any one stage of the building, all stages are to be evacuated. In the event of a fire or emergency evacuation both academic and technical staff will assist in ensuring that the building is cleared; please follow their instructions. On leaving the building you must make your way to the assembly area for your building. Do not stay in front of the building. Fogg – West Square (behind Student Union) Joseph Priestley – Library Square Bancroft – Geography Square A map showing the assembly point is located at every fire alarm point. Do not leave the assembly area or re-enter the building until given permission to do so by a member of staff authorized to do so. The fire alarms will briefly sound during routine maintenance checks: do not confuse this with the continuous two-tone sound for a fire or a bomb threat. Fogg, Joseph Priestley and Bancroft Buildings will undergo an annual Fire Safety inspection overseen by OHSD, a report is generated and its recommendations acted upon An inventory of hazardous materials is kept in the ‘red fireman’s box’ located in each building, this data is accessed by the fire brigade on arriving at the scene, the contents of the box are reviewed at agreed intervals 10. FIRE MARSHALS The following staff members are designated fire marshals and it is their responsibility to ensure that their areas are cleared of people in the event of the activation of a fire alarm. You must listen to their instructions and promptly evacuate the building when told to do so. All fire marshals will undergo training through QMUL ESD; the training will be reviewed every 3 years to ensure that it is up to date in terms of College procedures and legal requirements. Duties will be in line with ‘Duties and Responsibilities of Fire Marshals’ produced by OHSD.

FIRE: SOLVENT STORES (Joseph Priestley Building) These areas are protected by flood CO2 extinguishing systems, activated by thermostats or manual operation. The system cannot be stopped once it has been activated. Activation of the system also activates the fire alarms throughout the building. Do not enter these areas after the system has been operated until you have been informed that it is safe to do so. 12. SECURITY College security can be contacted on ext. 13 5000 If you cannot contact College Security in an emergency: Dial (9) 999 and report the emergency, for example fire or injured person. Specify the building and location at Queen Mary, University of London, Mile End Road, E1 4NS. If possible try to arrange for someone to meet the emergency services when they arrive to direct them to the emergency. The School of Biological & Chemical Sciences occupies The six storey G. E. Fogg Building on the east side of Bancroft Road (including the bridge over the road), the Joseph Priestley Building on the east side of campus and laboratories on the ground and 5th floors in the Bancroft Building. The Fogg, Joseph Priestley and Bancroft buildings are open from 8.00 a.m. to 6.30 p.m. Monday to Friday. The buildings are closed on Saturday, Sunday and when the College is officially closed. Access to the Fogg building is via the ground floor entrance on the east side of the building, through ‘D’ door or via Bancroft road, Bancroft can be accessed out of hours. Access to the Joseph Priestley building is through the ground floor atrium entrance. Access to the Bancroft building is through the ground floor entrance in the Library Square. The room numbering indicates the floor level and room number, e.g. G.04 is room 04 on the ground floor. Personal property is the responsibility of the individual and it is prudent to guard against thefts at all times. Losses or suspected thefts should be reported as soon as possible both to the College security staff (tel: 5000) and the SBCS buildings manager (ext 6339). 13. BOMB THREAT In the event of a bomb threat, if evacuation is thought appropriate, the alarm will sound as for a fire. You should go to the appropriate assembly place for the building you are in, and await further instructions from the College security staff and the Police.

CHEMICAL CONTAMINATION OF EYES AND SKIN Be aware of the location and use of eye baths and emergency showers. If a corrosive or irritant chemical enters the eye, at once hold the eye open use an eyebath to irrigate with copious quantities of cold water for at least 20 minutes. 15. WORKING ACCESS TO THE FOGG, JOSEPH PRIESTLEY and BANCROFT BUILDINGS ACCESS AND NORMAL WORKING ARRANGEMENTS During term time the Fogg and Joseph Priestley buildings are open for normal working from 8.30 am to 5.30 pm, Monday to Friday. The Fogg and Joseph Priestley buildings are closed on Saturdays, Sundays and at all times when the College is officially closed. Access to the Fogg, Joseph Priestley and Bancroft buildings are kept closed by a card-activated magnetic lock system and should be securely shut after use, to maintain the security of the building. Loss of a security card must be reported immediately to the Head of School or his/her deputy or Buildings manager. Security cards are not transferable and must be returned to the College Security Officer when no longer required, if a security swipe card is lot there will be a charge levied by security for its replacement. 16. OUT OF HOURS ACCESS AND WORKING ARRANGEMENTS No one is permitted to undertake any experimental work anywhere in the Fogg, Joseph Priestley and Bancroft buildings without an outside hours risk assessment being in place, no dangerous work can be undertaken, this would include the use of cryogenic substances or otherwise dangerous procedures. It is advised that the person working alone informs security (ext. 5000) of their situation and/or contacts suitable person to let them know where they are, if possible arrange for someone else to be present whilst in the lab. An out of hours RA must be completed before work can begin Outside working hours for JP should follow the outside working hours protocol, appendix 16 For the purposes of research workers, out of hours is defined as between 20:00 and 08:30 hrs Monday to Friday and anytime at weekends. 17. WORKING ALONE AND OUTSIDE HOURS College Standard for lone working at http://qm-web.ohsd.qmul.ac.uk/standard/index.html and search for ‘lone working’ or direct document link http://qm-web.ohsd.qmul.ac.uk/documents/standard/sem/old%20guidance/76997.pdf SBCS website http://www.sbcs.qmul.ac.uk/students/healthandsafety/index.html .

ASSESSMENTS UNDER COSHH (Control of Substances Hazardous to Health) The Legal Requirement The key provision of the Control of Substances Hazardous to Health (COSHH) Regulations 2002 (see Appendix 1) is Regulation 6, which requires employers to make suitable and sufficient assessments of the risks to health arising from hazardous substances at work. Each assessment should establish what needs to be done to meet the requirements of the rest of the Regulations. Regulation 6 includes the following: An employer shall not carry on any work which is liable to expose any employee [or any other person who might reasonably be expected to be on the premises] to any substance hazardous to health unless he has made a suitable and sufficient assessment of the risks to health created by that work to the health of those employees or other persons and of the steps that need to be taken to meet the requirements of these Regulations. The assessment required by section (1) shall be reviewed forthwith if: There is reason to suspect that the assessment is no longer valid; there has been a significant change in the work to which the assessment relates, and, where as a result of the review, changes in the assessment are required, those changes shall be made. OHSD would expect that RA’s were reviewed every 3 years Purpose of the Regulation The purpose of doing an assessment is entirely practical: it is to ensure that correct and sensible decisions will be reached about how to control and respond to hazardous substances arising in the course of work. The principle throughout the COSHH Regulations is that the precautions which should be taken are determined by the nature and the degree of risk in each case. It is therefore essential that, at the outset, a valid and informed judgement is made about the risks to health. This means considering a series of questions about the work to be sure that all relevant aspects have been taken into account. It does not mean carrying out a piece of original research or producing a learned thesis on the properties of a substance. Above all, it is a matter of stopping to observe, listen, read, and think before acting. A “Suitable and Sufficient” Assessment To be suitable and sufficient, the assessment should go through a series of questions, suggested below. The first six are aimed at establishing the nature and extent of the risk; the last one considers the precautions to take in response to the risk. The risk arising from the work is related not only to the ability of a substance to cause harm but also to the amount of the substance and the ways and extent to which people may come into contact with it. There are a series of model risk assessments available which cover experimental procedures, substances encountered, equipment used and waste disposal procedures, and these are in the model risk assessments folder. Where groups of people are doing similar work and are similarly exposed to the same types of hazardous substances, the assessment can be based on a representative sample of people. Equally, in situations involving large numbers of hazardous substances, such as research laboratories, the substances can usefully be grouped together for the purposes of the assessment, on the basis of similar hazard or treatment. The assessment does not necessarily Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 11 have to be done by just one person - several people may be involved in providing information for different questions. However, the information should be brought together at the end of the exercise, and considered as a whole, before taking action. What hazardous substances are there? This is a matter of recognising the hazardous substances used in, or arising from, the work. There are, of course, many kinds. They can be in the form of gases, vapours, liquids, fumes, dusts or solids, or they can be micro-organisms. They may arise from materials used, stored or handled in any process, intermediates or by-products produced or given off, or the finished products of any process. They may arise from materials used in activities incidental to production, such as maintenance, cleaning or repairs. They can also arise from accidental spills or leakages. Hazardous substances can be recognised by obtaining and reading information from suppliers, including their labels on packages and containers (CHIP Regulations), from trade and technical literature and HSE Guidance Notes and data sheets. Of course, hazardous substances can also be recognised as they have always been: by in-house product and process knowledge and by previous experience. What are the harmful effects? The effects of those substances on the body should be considered and, where appropriate, the effects of mixtures of substances, which can sometimes be greater than that of each on its own. The effect will partly depend on the form that the substance is in and the way it enters or acts on the body, e.g. by inhalation, ingestion, contact with the skin or absorption through the skin. Information on the harmful action of any substance should be sought from the same sort of sources as in question 1. Where will the hazardous substance be present? All possible locations should be considered, i.e. all areas of use, storage, collection, disposal or discharge. The potential for ‘escape’ at each stage should also be borne in mind. Who may be affected? The next step is to identify the people who may be affected at each of the identified locations. They could be brought into contact with the substance if they either work with it directly or are in the vicinity of where it is used, stored or collected, or from where it is discharged. How great is the degree and extent of exposure? Any decision about the degree and extent of exposure must be based, first and foremost, on observation of and enquiry into working practices and experience. This provides a ‘yardstick’ for deciding how precisely exposure needs to be evaluated, and against which to consider the nature of the precautions to be taken. Besides inhalation routes, exposure can arise from contamination of skin, clothing, food, drink and smoking materials; the significance of all routes should be considered. Where it has been decided to control exposures by containing a substance within a closed system, routine exposure may, depending upon the reliability of the containment, be regarded as negligible. How do the exposure data compare with recognised standards? Information on exposure will usually have little meaning unless it is related to some reference point. The next step is therefore to compare the results obtained with accepted standards Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 12 representing, at least, the “adequate control” required by COSHH Regulation 7. These standards may be prescribed or approved occupational exposure limits for inhaled substances, or else self-imposed working limits or industry standards. The results of the comparison will determine the action which should be taken to limit and further reduce exposure. What action should be taken in response to the assessment? Once the risks have been assessed, the next step is to decide what action needs to be taken to meet the requirements of the other COSHH Regulations. Of prime importance is deciding what more needs to be done, if anything, to achieve and sustain adequate control of exposure, or preferably, to prevent it altogether. The control measures should be weighed up in terms of their effectiveness, certainty and reliability, the more sure and reliable methods being preferred. Elimination or substitution of the substances should be the first choice, followed by engineering control measures. Arrangements for maintaining and testing the control measures to ensure they continue to operate as intended should also be worked out. It is also necessary to decide what other precautions may need to be put into effect, such as routine monitoring of exposure, health surveillance procedures and training of employees. Results In all but the simplest cases, the assessments should be recorded, to ensure continuity of awareness among managers and supervisors, and to ensure that other people who may need to know are properly informed. Among the latter may be employees or their representatives and Health and Safety Inspectors. Also, unless the assessment is recorded, it will not usually be possible to make a correct judgement about when it should be reviewed. Therefore, unless the assessment can be immediately or readily repeated at any time, or concerns work of very short duration, it should be set down in a record. Review The assessment should be reviewed if there is any reason to suppose that it is no longer valid or if there has been a significant change in the work, health surveillance, and new information about health hazards, a change in personnel, or a change in materials, plant, control methods, process or volume of production. Assessment Forms Suitable forms for the COSHH assessment exercise for chemicals can be obtained from the Chemistry Stores; for a copy of the form see Appendix 13. The form is available electronically from the Safety website; one copy is for the user of the chemical(s), one copy is to be given to the supervisor and one copy to the Safety Officer. N.B. The assessment should include products and by-products as well as reagents and solvents. The form must be countersigned by the supervisor or the appropriate person. Procedures should be subject to periodic assessment and review [33]. Three copies should be made and distributed as for the COSHH forms. There are also COSHH forms available from the Risk Assessment folder or from the College safety website http://qm-web.safety.qmul.ac.uk/index.html http://www.sbcs.qmul.ac.uk/students/healthandsafety/index.html 24. COSHH, BIO-COSHH, FIELDWORK and GENERAL RISK ASSESSMENT FORMS The assessments under COSHH are the cornerstone of the Regulations and the key to fulfilling the other requirements. They are intended to enable and encourage employers to set priorities for the allocation of resources on the basis of the highest risk, and promote a Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 13 sensible and flexible approach to reducing the risks presented by work involving substances hazardous to health. NOTE: Copies of the Health and Safety at Work, etc. Act 1974 and the COSHH Regulations are available for inspection from the College Safety Adviser. All risk assessments to be stored within the laboratory / room where the work is taking place, be up to date and available for inspection. Two copies are needed, one for the work area, the other for reference stored in another location. It is advisable to have electronic versions available in addition to the paper copies in the laboratory. If the work changes substantially over the course of a project, a new assessment must be written. After 3 years the assessment must be reviewed and a new assessment written to replace the old one The risk assessment applies not only to the work being done but the people involved as well, if new members of the group arrive or leave, then new assessments must be written. 25. GENERAL LABORATORY AND OFFICE REGULATIONS The following rules, which are by no means exhaustive, cover many of the situations which you will encounter in a laboratory. Before starting any work you should ensure that you have taken all reasonable precautions against any foreseeable accident, taking due notice of the toxicities of the substances with which you are working. Offices and Laboratories Offices and laboratories should be kept clear of all unnecessary obstacles, the Storage of bicycles is strictly prohibited in areas other than those that have been designated Passageways Doorways, landings, gangways and passageways must be kept clear and free from obstructions at all times. The storage of bicycles in passageways is prohibited. Fire doors, which are clearly marked as such, must not be wedged, propped or tied open except for limited periods when equipment and cylinders are being moved and floors cleaned. State of Laboratories One of the best precautions against an accident is a clean and tidy laboratory; a cluttered bench or floor is a prime accident site. Research workers are responsible for keeping their own benches clean and tidy. Cleaning materials are available from the Technical Staff and the Stores. Your co-operation with both the cleaners is required to enable them to do their jobs efficiently and safely. Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 14 Food and Drink Food and drink may not be consumed or stored in the Fogg, Bancroft or Joseph Priestley buildings except in designated areas. Smoking Smoking is banned throughout the Fogg, Bancroft and Joseph Priestley building’s and this ban now extends to the whole of the Queen Mary campuses Eye Protection Safety spectacles must be worn at all times in any laboratory, unless a suitable risk assessment is in place detailing why safety glasses should not be worn There is a danger to the eyes in all laboratory work from splashes and explosions. The School therefore provides all new workers with a pair of safety spectacles to the Current British Standard. These glasses fully shield the eyes and fit over most prescription glasses. Prescription Safety Spectacles are available and the links below give details of obtaining prescription safety spectacles. http://qm-web.ohsd.qmul.ac.uk/documents/standard/64344.pdf http://qm-web.ohsd.qmul.ac.uk/services/Eye%20Care/index.html) lab workers can go to other eye care companies, but the School / PI would have to pick up the cost. You are required to wear safety spectacles at all times in the laboratory: the hazard may not be of your own making but that of a co-worker. Contact lenses increase the risk to the eyes in the event of an accident. It is not advisable to wear contact lenses in the laboratories unless full goggles are worn. Contact lenses may give rise to many hazards: they may slip at an awkward moment, but more importantly they are difficult to remove quickly in the event of an accident should the eyes be splashed with chemicals. They also reduce the flow of natural fluids to the eyes which help to move any contaminant; moreover, they may trap the contaminant behind the lens and can actually worsen the accident. Protective Clothing (PPE) Failure to wear a lab coat or other PPE may result in exclusion from laboratory areas. When carrying out practical work a laboratory coat should be worn. Laboratory coats are supplied by the School and must not be removed from laboratory, unless to be laundered through the School laundry contractor. Failure to wear a lab coat may not only have consequences of personal injury, but also damaged clothing will not be replace if a lab coat has not been worn Protective gloves and aprons are available from the Stores and should be worn Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 15 when necessary. Workers should be aware that no type of glove can exclude all substances and that glove materials themselves can be allergenic. Contaminated gloves must not be worn. No gloves are allowed outside the laboratory, exception may be granted if a suitable risk assessment has made, for exceptional procedures. For further information on gloves please see the College Health and Safety website at Lab coats will be laundered on a regular basis Any PPE (Personal Protective Equipment) that is damaged or cannot be cleaned should be disposed of, by a suitable route http://qm-web.safety.qmul.ac.uk/index.html Dust Masks Dust masks for use when working with non-toxic dusts or powders are available from the stores. These masks should always be used when making or scraping thin layer chromatography plates. Safety Shields Safety shields and Face Visors should always be used when working with potentially explosive materials or hazardous materials where safety glasses are not appropriate Footwear The wearing of open-toed shoes in laboratories is potentially dangerous in the event of a chemical spillage, and is therefore strongly discouraged. When moving gas cylinders or other heavy objects that could crush the toes or feet, suitable protective footwear should be worn. Manual Lifting If lifting weights over 25Kg is a regular occurrence, then the attendance of a manual lifting course is mandatory Fire Fighting IF EVER IN ANY DOUBT, USE THE BREAKGLASS AND EVACUATE THE BUILDING, DO NOT TAKE ANY RISK WHEN TACKLING A FIRE The following are the main types of fire fighting equipment provided in the Joseph Priestley building: CO2 fire extinguishers, foam extinguishers, and fire blankets. HFFF extinguishers are located in some specific areas. Never use foam or water when the fire involves electrical apparatus, use CO2, for alkali metal or metal alkyls dry powder. When tackling a fire, however small, always ensure that you have a reserve supply of extinguishers, make sure you have a clear exit from the fire area and do not take any personal risk. If in any doubt about your ability to tackle the fire activate one of the fire alarm call points which are on each floor on the exit routes from the laboratories. Call the fire brigade as detailed on the fire action notice by the call point. Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 16 Unattended Experiments Overnight experiments in Joseph Priestley must follow the SBCS overnight protocol; these are displayed in the laboratories. Unattended experiments are the most frequent cause of fire and floods. The running of unattended experiments can usually be avoided by careful planning. When experiments or equipment must run overnight, or be left unattended, prior approval must be sought from the academic supervisor or his nominee and a signed notice, available from the Stores or the Technical staff, must be clearly displayed with all the relevant information including the name of the person in charge of the experiment, his telephone number and the emergency procedure to be followed in the event of an accident. Distillation experiments should NOT be left unattended unless specially designed Solvent stills’ and other equipment used in the drying of solvents must NOT be left unattended If any experiment would cause a serious hazard if one of the services in use failed, it must not be left unattended. Waste Disposal (see also College Safety Regulations: Waste Disposal Procedure) ALL WASTE IS DISPOSED OF FOLLOWING EITHER LOCAL GUIDELINES OR THOSE GUIDELINES SPECIFICALLY LAID DOWN BY HSE AND ITS VARIOUS AGENCIES The disposal of all waste materials must be carried out with care and with consideration as to its ultimate destination. Some chemicals (e.g. Schedule 1 poisons such as cyanides, arsenic compounds, etc., Radiochemicals, substances which pose bio-hazards etc.) will only be used under procedures that include specific instructions for their safe disposal. Before commencing any experiment you should be aware of the procedure for safe disposal of any unwanted products and unused reagents. This information can often be found in the original supplier’s catalogue, safety data sheet which accompanies the material when purchased, or online from ACS, Aldrich, Royal Society of Chemistry and others. Waste Glass: Yellow bins are provided for the disposal of waste glass, these are common in JP, Fogg and Bancroft labs, and they will follow the same route for disposal as the yellow bins used for non-hazardous biological waste Clean (i.e. washed and uncontaminated) glass and glassware may be put in the yellow bins for disposal. Winchester bottles, when empty and clean of all chemical contamination, will be disposed of by contacting Jalal Hamdan in the Joseph Priestley building. All other glass, (glass vessels, glass bottles, broken glass, etc., which is contaminated, has traces of chemicals adhering to it or which carries a label or labels) must be put in the glass bin to indicate that it has been in contact with “chemicals”. Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 17 Chemicals other than aqueous solutions of low toxicity must not be poured down the sinks. Disposal of concentrated acids should be via the lab sink in either a fume hood or bench sink followed with copious amounts water, the acid should be diluted first, when diluting acids always add the acid to water. Solvent residues, including wet residues, must be placed in the appropriate solvent containers which are situated in laboratories. In the solvent delivery system, room (1.30) in the Joseph Priestley Building, there are separate containers which are supplied for the bulk disposal of halogenated and non-halogenated solvents and are clearly marked as such. Halogenated and non-halogenated solvents must never be mixed as they are disposed of by different procedures; also, there is a possibility of a strongly exothermic reaction between the different kinds of solvents. When the lab containers are full, transfer the contents to large containers in the solvent delivery system room (JP 1.30), 10L container for Chlorinated and 25L for non-chlorinated. When these are full (do not fill them right to the top) contact JP Stores for collection and replacement. The disposal of all other chemicals must be approved by the academic supervisor. Destruction of old bottles of moisture-sensitive reagents such as alkyl lithium’s may best be done “in-house” by the research workers involved in their use. A hazard assessment will be required and due care must be exercised as in any other chemical procedure. Inexperienced workers must seek advice from a competent person. If commercial disposal of unwanted or waste chemicals is required then this must be approved by the academic supervisor and arranged through the School Safety Officer, who should first be provided with a list (preferably in electronic form) stating the quantities and locations of the substances involved. Known and unknown chemicals must be packed separately in secure containers, solids being packed separately from liquids, and organic chemicals separately from inorganic chemicals. A list of the chemicals with an estimation of the quantity of each must be placed on the outside of the container. The waste materials will then be taken to a secure area before removal from the College site. Chemicals must not be emptied into waste bins. Experiments and procedures that will involve or evolve gas should normally be carried out in fume cupboards (subject to exceptions that may be approved by the Safety Adviser 26. CRYONGENIC LIQUIDS AND SOLIDS (Liquid Nitrogen, Helium, solid CO2) Areas where potentially Asphyxiant gases are used or stored have either fixed low Oxygen monitoring, specific sensors for special gases or a personal oxygen monitor is supplied. Training will be given in the handling of cryogenic liquids and solids; you will not be allowed to handle these materials, unless trained. A record of such training will be kept. Training will be given in the use of Dewar’s and cryogenic storage Laboratories or areas where Asphyxiant gases may be present will monitored by low Oxygen monitoring sensors, or by personal low oxygen sensors (supplied). All such Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 18 equipment will be regularly serviced. Thermal gloves should be worn when transferring liquid gases from one container to another and the operation should always be carried out in a well ventilated area. Liquid nitrogen is available in 160 litre or 200 litre containers. Small 25 litre containers are kept in some laboratories. Apparatus which is open to the atmosphere must not be cooled using liquid nitrogen since the condensation of oxygen can be very dangerous. Users of argon atmospheres should be aware that this gas condenses at the temperature of liquid nitrogen. If liquid argon becomes trapped in a closed system and is allowed to warm up then a dangerous increase in pressure may occur. Liquid helium presents special hazards and its use must be discussed with the academic supervisor and Safety Co-ordinator before commencing work. Do not travel in lifts with cryogenic liquids. 27. GAS CLYLINDERS - see also College Safety Regulations: Use of High Pressure gases http://qm-web.safety.qmul.ac.uk/index.html The supply, delivery and installation of gas cylinders is the responsibility of the Colleges supplier, contact details are available from stores or from School Safety Co-ordinator Gas cylinders present special hazards. The general precautions for handling and storing gas cylinders listed below should be followed at all times. Only those cylinders in actual use shall be kept in laboratories. These must be chained to a firm support or stored in an approved stand. Free-standing cylinders are dangerous and thus are forbidden in all laboratories. Where fitted the valve protection cap should be left on each cylinder until it is actually in use. Do not place any cylinder where it may become part of an electrical circuit. Never use oil or grease to lubricate the threads of a cylinder. Never use Teflon tape on oxygen cylinder and avoid using it on other cylinders. Use only the correct type of pressure regulator for the gas concerned. Never use oil or grease to lubricate the threads of a cylinder. Pressure regulators should be certified safe by a competent person or replaced at intervals not exceeding once every five years. The main valve should be opened slowly with a proper key; too rapid opening may cause an explosion. Never discharge the contents of a cylinder without the use of a pressure valve or a control valve. Where a gas is passed through a liquid mixture, a pressure relief Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 19 device and an anti-suck-back trap should be used. The correct arrangement is: cylinder - suck-back trap - pressure relief device. Do not attempt to move a gas cylinder unless you are competent. Protective footwear should be worn. Four-wheeled cylinder trolleys are provided and their use is strongly recommended as they minimise the risk of the cylinder toppling over. The contents of gas cylinders may also have properties which make them hazardous, e.g. because they are flammable, toxic, corrosive, etc. These properties can be found by reference to the technical information sheets. Other important factors which should be considered are the possible formation of hazardous products, such as acetyl ides formed by the action of copper or copper alloys with acetylene or gases which contain acetylene as an impurity, or the formation of fulminate when mercury is used in the presence of ammonia, etc. Toxic or flammable gases must be used in fume cupboards. The cylinder used should be of the minimum size needed for the reaction to ensure that all the gas is used in a reasonable amount of time. The system should be tested for leaks using compressed air, nitrogen, or any inert gas before using the chosen gas (es). Do not, inadvertently or otherwise, connect two different gas cylinders together. Rapid mixing of the contents can occur under such circumstances, causing a possible explosion hazard. 28. REFRIGERATORS AND DEEP FREEZERS Refrigerators and freezers should be cleaned on a regular basis. All containers must be clearly labelled (chemical name, your name, and date) and stoppered or sealed. These must be of the spark-free type, whenever possible. Food and drink must not be stored in refrigerators and deep freezers which are used for chemicals etc. Similarly, chemicals must not be stored in refrigerators and deep freezers which have been supplied for food storage. Only materials which are unstable at room temperatures, recrystallizing solutions in adequately stoppered containers, or reaction mixtures may be stored. All material stored in fridges and freezers when no longer required should be disposed of by a suitable route. All refrigerators and deep freezers are regularly checked and defrosted, at which time all unlabelled materials will be removed and destroyed. Refrigerators and deep freezers are operated at pre-set temperatures: do not alter the temperature settings. 29. FUME CUPBOARDS(LEV) Fume cupboards may be used for the storing of volatile and/or toxic materials or for experimental work but not for both. Check that the fume cupboard is working before using it, check the flow meter and that LEV inspection is in date, Report any failure or suspected failure immediately, for Joseph Priestley contact Mr Jalal Hamdan (ext 2024) Agha Shah Stores and any such failure in the Fogg building to Alan Philcox or to Alan Philcox in any event. All LEV has record of maintenance and the interval at which maintenance is performed. The efficiency of the fume cupboards is to be checked at regular intervals by the Laboratory Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 20 Technician. You are required to keep the fume cupboard fronts closed to the “stop” position when not using them and to have them open as little as possible when actually working in them. The efficiency of the fume cupboards drops as the opening is increased. Always leave the fume cupboard clean and tidy. As soon as you have completed the reaction in the fume cupboard you should remove your apparatus as the fume cupboard could be needed in an emergency. No experiments which generate large volumes of toxic/flammable vapours should be carried out in the fume cupboards in the research laboratories. The maximum permitted rate of release is about one litre per minute. Large scale experiments should have a separate risk assessment. There are vented cupboards under the fume hoods for the storage of volatiles and flammable compounds Do not leave unlabelled chemicals in fume cupboards or anywhere else. These will be disposed of immediately. Once the experiment has been set up the sash should closed down, all fume not in use or being used have the sash down, this is especially important overnight where energy saving is a priority 30. WATER All water taps should be securely turned off when not in use. Where an apparatus is to be connected for long periods, reinforced or plastic tubing must be used and the connection secured with either jubilee or hose clips. The connection should be inspected at regular intervals. Connections to glassware should be made using 20 SWG tinned copper wire, or jubilee clips, cable ties or special plastic adaptors. Condenser outlet leads must be made secure to the drains or the trough, the outlets of which must be free from blockages. An overnight flood can cause great damage and inconvenience. Purified water is available on all floors in the Fogg Building, except the 2nd floor Ice is available from 4th floor and 3.04 teaching laboratories, as well as purified water. Purified water and ice are available on floors G, 1 and 2 of the Joseph Priestley Building. If possible use our water resources sparingly 31. ELECTRICTY: School Code of Practice to Conform to Electricity at Work Regulations(1989) The Electricity at Work Regulations 1989, which came into force on 1 April 1990, is Made under the Health and Safety at Work etc. Act 1974. The Regulations apply to all users of electricity at work and have statutory force. Infringements of the Regulations may leave individuals open to prosecution. The Regulations and this Code of Practice are applicable to all staff and students working in the School. The purpose of this Code of Practice is to ensure that the College’s and School’s responsibilities under the Regulations are properly discharged. Infringements of this Code may lead to disciplinary action. In particular, this Code requires procedures to be adopted to ensure that: The College and the School exercise proper responsibility under the Regulations for the health and safety of its staff at work and others who work in the School. Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 21 All electrical equipment will undergo PAT (Portable Appliance Testing), this will be performed under contract managed by QMUL Estates, record of testing will be supplied to SBCS and will contribute to the School asset register. Equipment which fails PAT will either be repaired and retested or disposed of. The construction of new equipment and the modification and repair of commercial equipment are carried out in accordance with proper standards of safety. Staff and students undertaking any form of work on electrical apparatus are properly trained. Under no circumstances will staff or students engage in work which involves access to live conductors. All class 1 electrical equipment and supporting framework must be earthed. If in any doubt consult estates electrical staff or a qualified electrician. Multiple adapters must not be used: their use is forbidden under all circumstances. Where it is absolutely necessary to work on live circuits, including testing, such activities should only be carried out by a competent electrical craftsman accompanied by a second person with similar qualifications. Apparatus which repeatedly “blows” a fuse must be sent for repair or disposed of. Electrical equipment must be switched off and unplugged when not in use. In cases where electrical equipment is left turned on for long periods or permanently, e.g. refrigerated cabinets, ovens, spectrometers, etc. an appropriate notice should be displayed next to the plug and switch. Work on the School’s wiring installation or major electrical equipment, will be undertaken either by the maintenance Department or by a contractor approved by the Maintenance Department. All new work will be covered by a certificate confirming that the installation or equipment has been tested and handed over in a safe working condition. Wherever possible portable electric tools should be battery operated; failing this, mains equipment should be of the double insulated type (Class 2). Other types of mains operated (Class 1) tools should only be used when protected by a sensitive Residual Current Circuit Breaker. Class 1 tools should not be used in wet conditions or in a confined space. Ultimately it is the responsibility of the Head of School to ensure that all electrical equipment used in the School, including that owned by members of staff, is tested and inspected regularly. In practice this routine testing will be carried out by those members of academic, technical and research staff with responsibilities for the teaching and research laboratories and for School services. It is the responsibility of the Maintenance Department to ensure that the mains wiring installations should be tested every five years. An inventory and test record must be maintained and be available for inspection in respect of both sets of inspections. Subject to the above, it must be a condition of being allowed to work in the School that all such workers do not interfere with the electrical installation or equipment in the School and that any apparatus connected to the supply must not be a source of hazard: for example, Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 22 sockets must not be overloaded or temporary connections made to cables. It is the duty of all staff and students to bring to the attention of management any apparent defect in the installation or equipment. It is the duty of management to take immediate action when such reports are received. By this Code of Practice the Head of School and the Safety Advisers inform staff and students of their obligations under items 10 and 11. Electrical hazards or defects should be reported immediately to your laboratory technician, academic supervisor, or to the Safety Adviser. All electrical equipment will undergo PAT (Portable Appliance Testing) in line with OHSD guidelines Please ensure that all unnecessary equipment is unplugged if not in use 32. GAS Ensure that all gas taps are turned off when not in use. Always use a well made and secure connection at both ends before using the supply. Replace and discard damaged or perished tubing. If gas is smelt at any time, check that all taps are closed, ventilate the area for a few minutes and then check again for a smell of gas. If gas is still present report the fact immediately to the Safety Coordinator and/or estates or other suitable person. Laboratories should be equipped with a safety ‘Knock off’ switch 33. STORAGE OF FLAMMABLE SOLVENTS Flammable solvents/reagents are to be stored in the vented cabinets under the fume hoods No bottles of solvents or reagents will be placed on the floor at any time Flammable solvents in quantities greater than 0.5 litres should be stored below hand level. Winchesters of flammable solvents must be stored only in the steel or steellined cupboards provided in each laboratory, never in under bench cupboards. Ethers and some alkenes form peroxides and should not be stored for longer than 6 months. Sodium wire residues from bottles of dried solvents MUST be destroyed using methanol by the person emptying the bottle. Bottles containing sodium wire residues must never be put out for general disposal as empty bottles are washed with water. 34. STORAGE AND DISPOSAL OF CONCENTRATED ACIDS These should be stored in a well ventilated place, separate from organic solvents. Cabinets are provided for this purpose under the fume hoods or in designated cabinets Concentrated acids should be disposed of down the sink with copious amounts of Water, never add water directly to concentrated acids, and always add the acid to water to dilute it. When disposing of concentrated acid use large volumes of water. Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 23 35. LASERS The use of lasers must be discussed at the planning stage with the School Safety Advisers and College Safety and Laser Safety Advisers (Paul Cassell). http://qm-web.safety.qmul.ac.uk/index.html 36. GLASSBLOWING Any glassware given in for repair must be clean, dry, and free from solvent vapour, before it is sent away for repair 37. IONISING RADIATION Special regulations apply to the use of radioactive materials and to the X-ray Laboratory. Only designated radiation workers are allowed to work with radioactive materials and X-rays. Any person who intends to work with radioactive materials or X-rays must discuss the proposed scheme of work in advance with the Radiation Protection Officer, currently Mr. S Pestaille, School of Biological and Chemical Sciences, who will make the necessary arrangements and supply further information. Radioactive materials must not be brought into the School or ordered without the written approval of the Radiation Protection Officer and the School Safety Adviser or his deputy. The users of radioactive materials are required to keep a record of the use and method of disposal of all radioactive materials under their control. All projects using radio activity are subject to approval by OHSD 38. ORDERING OF TOXIC, RADIOACTIVE OR BIO-HAZARDOUS SUBSTANCES No order will be placed without completing the COSHH form, at the bottom of the order form. The Stores Supervisor will not order any toxic gases, Schedule 1 Poisons, Radiochemicals or Bio-hazardous Substances unless the order has been approved by the licence holder or suitable person. All orders for hazardous material must have the risk assessment on the order form filled in, or the order will not be processed. There are procedures in place to ensure that when radioactive material is ordered the activity limit for the isotope is not exceeded. Schedule 1 Poisons will be issued from stock after the purchaser has signed the Poison Register. The Stores Supervisor will issue a Hazard Warning Card which shall be kept close at hand while the material is in use. The academic supervisor’s written consent is also required. See also section 14.28 (Schedule 1 Poisons). All hazardous materials ordered through stores will follow all necessary HSE Guidelines 39. CHEMICAL HAZARDS Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 24 Chemicals must not be transported in the passenger lifts, unless packaged in accordance with HSE guidelines Before using any chemical for the first time, you must ensure that you familiarise yourself with all its known hazards. Appropriate Safety information may be obtained from the Research Stores. The College Library has an extensive reference section on chemical hazards, “Hazards in the Chemical Laboratory” by G D Muir, which although not exhaustive, is one of the most readable. Data sheets can be accessed via the web through ACS, Aldrich and others. Non-inclusion in this and other standard reference works does not mean that the substance is harmless. A written assessment of the risk of any new procedure is required in advance and this must include any necessary precautions, first aid treatment where known, and the procedure to be followed in the event of an emergency. Academic supervisors and research workers are responsible jointly for the safe planning of all experimental work. Prior consideration and discussion must take place before chemicals are ordered or taken from the Stores and experimental work is started (see also section 19). The results of this assessment must be recorded on a COSHH form. COSHH, BIO-COSHH and General Risk Assessment forms are available on the School Website. Most chemical work is potentially hazardous and proper care must be exercised at all times in the laboratories. The following specific examples of hazardous chemicals or procedures are meant to illustrate some of the most significant hazards that may be encountered in normal laboratory work. Benzene: Highly toxic by inhalation and skin absorption. Prolonged exposure to high levels of benzene is known to cause cancer of the bladder. Benzene may only be used with a risk assessment in place, and the procedures followed for ordering this compound. Chlorinated Hydrocarbons: Chlorinated solvents and other chlorinated hydrocarbons are toxic by inhalation, ingestion, and skin absorption. Some solvents, e.g. CCl4, CHCl3, and Trichloroethene are extremely toxic and potentially carcinogenic. Such compounds should be used as little as possible; if they must be used then the work must take place in a fume cupboard. Chromic Acid: Chromium(VI) compounds are banned and should not be used Hydrofluoric Acid: Burns from this acid are very severe, exceptionally painful, and very difficult to treat, and take a long time to heal. The use of this acid is normally restricted to the College Glass Service. A risk assessment must be in place before using this material Mercury: Mercury is a cumulative poison. Except where it is necessary to permit access of air to register barometric pressure, all mercury surfaces MUST be enclosed. A risk assessment must be in place before using this element. Work with mercury should always be carried out using a tray to contain any spillages in a fume cupboard or other well ventilated area. Mercury spillages should be cleaned up promptly, using a water pump or Pasteur pipette. Small droplets may be removed with a suitable gum-forming proprietary device or covered with a paste made of equal parts of calcium hydroxide and sulfur which has been made into a slurry using water. Subsequent removal of the whole mass should ensure that all the Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 25 Mercury has been removed (repeat if necessary). Zinc powder is a good alternative 40. WORKPLACE EXPOSURE LIMITS(EH40) A list of compounds and their workplace exposure limits (EH40/2005) is obtainable from HSE website; this list is updated regularly and is to be used with COSHH as additional information for risk assessments www.hse.gov.uk/coshh/table1.pdf/ A list of substances prohibited under EH40 is contained within the document 41. SCHEDULED SUBSTANCES(1,2,3) A list of scheduled substances can be obtained from the web address above The 3 schedules list toxic chemicals and their precursors, which are subject to verification under the Chemical Weapons Convention. Anyone producing, processing, consuming, importing or exporting any of these chemicals must meet certain legal requirements. Further information is available from the CWC UK National Authority There are procedures in place for the ordering of these substances, consult the Joseph Priestley stores manager 42. POISONS All substances designated as poisons must be stored in a lockable poisons cabinet and inventory kept. Access to the poisons cabinet in Joseph Priestley stores is controlled by the store’s manager as a legal requirement. The JP Stores Manager is the only member of staff who is permitted access to the Poisons Cupboard. Schedule 1 Poisons will only be issued against the signature of the relevant academic supervisor, who shall have ensured that all appropriate precautions have been taken. All unused material MUST be returned to the Stores at the end of the day. When not in use the material MUST be kept in a secure locked poisons cabinet. 43. DRUGS, Schedule 1 Use of drugs for experimentation must follow Home Office procedures and is the responsibility of the PI and licence holder SBCS is licensed for schedule 1 drugs 44. CYANIDES The following procedure must be used: Request made to the Joseph Priestley building Chemistry Stores, with COSHH form (copies to both College and School Safety Officers) Notify Jalal Hamdan, who has been trained to use resuscitation equipment. Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 26 Minimum quantity of cyanide issued from Chemistry Stores. Appropriate First Aider (Jalal Hamdan trained in the use of the oxygen bottle) to be informed before work with cyanide begins. Working alone is forbidden, and at least one other adequately experienced person should be present. N.B. Experimental workers should be aware of the fact that a significant proportion of people cannot detect hydrogen cyanide by smell. Unused cyanide must be returned to the Chemical Stores as soon as possible. 45. CARCINOGENS, MUTAGENS AND SUBSTANCES TOXIC TO REPRODUCTION: All stored material must labelled following the GHS(globally Harmonised System) The material must be stored in a secure closed container at all times when not actually in use. The container must be labelled as to its contents, including a clear statement that it is either a known carcinogen or suspected of being carcinogenic. Disposable gloves should be worn when using the materials and the work should be carried out in a fume cupboard. Consideration should also be given to covering the work surface with a disposable material. At the completion of the work any disposable and covering materials used should be sealed in air-tight containers for proper disposal. Consult senior organic technician in advance. Safety pipettes must be used when handling liquids. If the skin has been contaminated, soap and water are the safest cleaning materials. Waste Disposal. The method chosen must not create any hazard either immediately or for the future. The best method is chemical destruction by a competent person. Biohazards: Advice on the safe handling of bio-hazardous materials should be obtained from SBCS Safety Co-ordinator or in consultation with OHSD Biological Safety officer, Mark Ariyanayagam: m.r.ariyanayagam@qmul.ac.uk 46. EXPLOSIVE SUBSTANCES No satisfactory protection can be offered in the event of a major explosion. A risk assessment must in place before the use of these compounds can be used. Satisfactory protection can only be obtained if the chance of a small explosion is anticipated, so that protective equipment can be built into or around the apparatus. It is essential therefore that all laboratory workers are aware of the possible sources of explosion and correctly assess the explosion hazards of their work. Compounds which readily detonate include many azides, organic perchlorates, acetylides, peroxides and polynitro compounds. Such compounds must be used only if an academic supervisor considers that it is essential as part of Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 27 the research programme, in which case approval for the use of the material must be given in writing. Clearly, a detailed assessment of the risks involved and necessary precautions must be carried out in advance and must be agreed in writing between the supervisor and the research worker. Explosive compounds can be detonated in a number of ways, the following being the most common in a laboratory environment: Shock - a slight movement is sufficient for the most sensitive compounds. Friction - stirring, removing a stopper, transfer of material, etc. Slight heating. The quantity of explosive material used or made should be kept to the absolute minimum required. Full precautions must be taken. The explosive substances and any apparatus must be behind a safety screen. A Grade 1 Impact Face Visor should be worn as should heavy duty gloves and a laboratory coat. The apparatus should be sited so that no other worker in the area could be injured if there were to be an explosion in the system in use. Additionally, other workers in the immediate area should be aware of any possible explosion hazards; a clear notice should be displayed at the place of work and on the doors into the laboratory. Accidents can result from the unwanted formation of explosive material, e.g. the formation of peroxides in old ether bottles, especially di-isopropyl ether. Care should be taken to ensure that such unwanted hazards cannot occur, e.g. by disposing of ethers safely when they are no longer needed. 47. DISTILLATION HAZARDS Laboratory distillation is considered a routine operation. However, serious fires can result if high standards are not maintained. The recommendations below cover the more obvious sources of danger. Additional precautions may be necessary in special situations. A limiting batch size of 0.5 litres is recommended for normal materials. Less experienced workers are recommended to use appreciably smaller amounts The solvent delivery system in room 1.30 is set up to provide the following dry solvents; Toluene, Dichloromethane, Diethyl Ether and Tetrahydrofuran. If other larger quantities of other solvents are required which are not on this list then permission must be sought from Dr Tippu Sheriff and Dr Chris Bray. General Precautions The following general precautions, many of which apply to all laboratory work, should ensure that distillations are carried out in a safe and efficient manner. Make sure you know the location of the nearest fire extinguishers etc (see Sections 2 and 14.10). Safety spectacles must be worn. . Apparatus Check the apparatus for flaws or cracks before assembly. Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 28 Use round bottomed or pear shaped flasks and air Liebig or coil condensers (not double surface condensers which may fail under vacuum). Procedure Ensure that the apparatus is not a closed system. Note that a closed system may be created if the distillate solidifies on cooling in the condenser. Do not fill the still pot more than two-thirds full. Prevent “bumping” by the use of boiling chips or a boiling stick or, if at reduced pressure, by use of an air bleed. If the compound is likely to oxidise nitrogen bleed should be used. Never put boiling chips into a flask where the solvent is already refluxing, this will cause the contents of the flask to be ejected. Use a water, oil (paraffin or silicone), or sand bath or a suitable electric heater. Paraffin oil baths should not be used above 180°C. Oil baths which are discoloured or fume when heated should be discarded. When distilling highly flammable liquids at atmospheric pressure fit the outlet from the receiving vessel with rubber tubing and lead it to a safe point away from any possible source of ignition When distilling toxic compounds the whole assembly should be placed in a fume cupboard. Distillations at reduced pressures must only be carried out using round bottomed or pear shaped flasks. Never use conical flasks! Distillation apparatus must never be left unattended unless it has been designed for automatic operation. Automatic operation means that the system includes prevention of overheating, heater cut-out in the event of water failure, etc. The system may then be left if it has been working satisfactorily for at least one hour. It is advised that checks are made from time to time on the distillation. Safety devices have been known to fail! Drying of Solvents The drying of solvents by distillation from chemically reactive agents such as sodiumbenzophenone presents a particular risk of fire. In addition to the general guidelines concerning distillation, the following additional points need to be noted. The distillation of flammable solvents in quantities exceeding 0.5 litres must be done in the Solvent delivery Room (1.30 Joseph Priestley). Such solvent stills should be protected by a device which cuts off the electricity supply to the still in the event that the cooling water supply fails. Solvent stills should not be operated outside normal working hours. Solvent stills should carry a notice to indicate who is responsible for their operation. The drying agent must be chemically compatible with the solvent to be dried. Thus Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 29 alkali metals must not be used to dry halogenated solvents, with which they can react explosively. If in doubt consult your supervisor or the literature. Lithium aluminium hydride should not be used for drying solvents. Very hygroscopic solvents, such as Tetrahydrofuran, may require preliminary drying (e.g. by standing over sodium hydroxide pellets) before they can be satisfactorily dried with sodium metal. Solid residues should not be allowed to accumulate excessively at the bottom of solvent stills. Sodium residues which have become coated with organic material often require extended treatment with methanol (at least overnight) before water can safely be added. 48. AUTOCLAVES Training will be provided in the use of SBCS autoclaves Autoclaves must not used if training has not been provided and satisfactorily completed A record of training must be kept. Autoclaves must be tested every year Autoclaves must have a valid insurance certificate If the autoclave is faulty or damaged in any way it must not be used. The fault must be reported immediately. 49. CENTRIFUGES Training will be given in the use of SBCS centrifuges Ultracentrifuges must not be used if training has not been provided and satisfactorily completed. A record of training must be kept. Ultra and high spin Centrifuges must be serviced regularly If the centrifuge faulty or damaged in any way, it must not be used. The fault must be reported immediately. 50. LEAVING THE LABORATORY Gloves must be removed and disposed of before leaving the laboratory. Gloves must not be worn outside the laboratory (this includes one handed glove wearing), Gloves from the laboratory must be assumed to be contaminated and this contamination must not be allowed to leave the laboratory and be spread throughout the building. If you are transporting samples or small equipment make sure it is free from contamination and transport without gloves. Lab coats or other protective clothing must not be worn outside the laboratory. Laboratory coats from the laboratory must be assumed to be contaminated and this contamination must not be allowed to leave the laboratory and be spread throughout Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 30 the building, by casual contact. For the safety and convenience of those remaining you should carry out the following steps when you finish an experiment and before you leave the laboratory. TIDY YOUR BENCH Dispose of all unwanted samples in a safe manner. This includes any samples in refrigerators and the cold room. Wash and put away all the apparatus you have been using. Label all samples clearly with your name, sample name, and date of preparation. Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 31 Appendix 1 THE CONTROL OF SUBSTANCES HAZARDOUS TO HEALTH REGULATIONS 2002 (COSHH REGULATIONS) The COSHH Regulations were made in the form of a statutory instrument under the Health and Safety at Work, etc. Act 1974. This means that the enforcement procedures and penalties for non-compliance with the regulations are the same as for the 1974 Act once the COSHH Regulations came into force on 1st October 1989. The formulation of the COSHH Regulations is the most significant development in occupational legislation since the Health and Safety at Work, etc. Act 1974. The 1974 Act places a general responsibility on employers to do all that is “reasonably practicable” to ensure the health and safety of employees, and a subsection extends this responsibility to protection from harmful substances. The COSHH Regulations are designed to safeguard employees, subcontractors, visitors - both official and personal guests - and students (i.e. anyone who might reasonably be expected to be on the premises) from substances which might be hazardous to their health, such as chemicals, dusts or micro-organisms. It should be noted that the COSHH regulations do not place any new general duties on employers or employees; they simply set out the principles which will allow the existing duties to be complied with and readily enforced. The requirements of the regulations represent what is already considered by industry to be good practice, and these are currently followed by many reputable organisations. Central to the requirements of the regulations is the carrying out of an assessment of any process which may involve exposure to substances hazardous to health. The assessment is the key to all the other regulations and is intended to identify the nature and degree of risk, and thus to enable those responsible to determine the precautions needed to comply with the other regulations. For most manufacturing companies and university laboratories the enforcing authority is the local Inspectorate of the HSE. For some premises, notably catering establishments, offices and shops, the enforcing authority is the local Environmental Health Department which is part of the district or metropolitan council. Factory inspectors and environmental health inspectors have broad enforcement powers. Prosecution is seen very much as a last resort, but, if a prosecution is successful, heavy fines and (at least in principle) imprisonment is possible. Those prosecuted may include: research supervisors, teaching laboratory supervisors, technicians, heads of department, and even the chief administrator (for us, the College Secretary) and/or the chief executive officer (for us, the Principal), as well as the institution itself (the College), i.e. any employee who has failed in his duty under the 1974 Act and the COSHH Regulations is liable to be prosecuted personally. However, a more likely form of action is the issue of an improvement notice requiring certain actions to be carried out by a specified date or, in more serious cases, a prohibition notice requiring a process or area to be shut down until certain remedial work has been completed. The following notes on the COSHH Regulations were issued by the Health and Safety Executive to conference delegates at various seminars held in 1988 to clarify the new regulations. They give a general outline of the COSHH Regulations, but in no way attempt to be an authoritative statement of the law. The section devoted to ASSESSMENTS UNDER COSHH expresses the views of the HSE, but the final decision as to interpretation will, of course, lie with the Courts. I. Introduction The aim of the COSHH Regulations is to set out, in a legislative framework, the Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 32 essential measures necessary to control exposure to substances hazardous to health. The broad scope of Regulations means that the same principles of control can be applied to all substances hazardous to health. The flexible nature of the requirements allows the precautions to match the risk and facilitate the introduction of technical developments. Revocation of many existing relevant statutory provisions should substantially simplify and improve standards of compliance. The Regulations require an assessment of the risk to health that may arise from the use of substances at the workplace, the establishment and the maintenance of the necessary control measures, and, if appropriate, monitoring of exposure and health surveillance. The Regulations apply not only where employees may be affected but also in the case of any person who might reasonably be expected to be on the premises. II. Application The COSHH Regulations apply to substances classified as being very toxic, toxic, harmful, corrosive, or irritant under the Classification Packaging and Labelling of Dangerous Substances Regulations (CHIP) 1984. They also apply to all other substances hazardous to health arising from work activities and include mixtures and compounds. The Regulations apply to micro-organisms, but do not cover hazards which arise directly from a person suffering from a disease, except where that person is an inpatient at a hospital, e.g. catching a cold from a co-worker is not included, but contracting a disease through working with pathological samples is included. COSHH will not apply where the Control of Asbestos at Work and the Control of Lead at Work Regulations are in force. III. Prohibitions Certain existing prohibitions are continued (e.g. the Carcinogenic Substances Regulations) and there will be revisions in line with a forthcoming EC Directive. IV. Assessment (see section 11) The purpose of an assessment is to enable a decision to be made about measures necessary to control substances hazardous to health arising from any work activity. It allows the employer to show that all the facts pertinent to the work have been considered and that an informed and correct judgement has been reached about the risks, the steps which need to be taken to achieve and maintain adequate control, the need for monitoring exposure at the work place, and the need for health surveillance. An assessment entails a systematic review to consider which substances, or types of substances, employees or other persons are liable to encounter, what are the effects of those substances, where the substances are likely to be present, and the ways and extent to which any groups could potentially be exposed. The detail involved in its preparation should be commensurate with the nature and degree of risk arising from the work. V. Control Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 33 The employer must ensure that the exposure of employees or any other person who might reasonably be on the premises to any substance hazardous to health is either prevented or adequately controlled. Inhalation of substances assigned a maximum exposure limit (MEL) should not exceed those limits and should be reduced below them to the greatest extent that is reasonably practicable. Inhalation of substances which have been assigned an occupational exposure standard (OES) should be reduced to that standard. If exposure exceeds the OES, control will still be deemed to be adequate provided that the employer has identified why the OES has been exceeded and is taking appropriate steps to comply with the OES as soon as is reasonably practicable. Control to the OES, or below it, can always be regarded as adequate so far as exposure from inhalation is concerned. In all cases, prevention or adequate control of exposure should be achieved by measures other than personal protective equipment (PPE) to the greatest extent that is reasonably practicable; i.e., the use of engineering controls is the first objective and PPE should only be used as a last resort. VI. Use of Control Measures Every employer who provides any control measure should ensure that it is properly used and every employee should make full and proper use of any control measure provided. VII. Maintenance, Examination and Testing Every employer who provides any control measure in pursuance of COSHH Regulation 7 (i.e. to control the exposure of employees) should ensure that it is maintained in an efficient working order and in good repair. The employer should ensure that thorough examinations and tests of engineering controls are carried out. In the case of local exhaust ventilation plant this should be done at least once every 12 months. Respiratory protective equipment has to be examined at suitable intervals and, for all control measures, a record (or summary) of the examinations has to be kept for 5 years. The objective of the Regulation is to ensure that all control measures which have been provided to meet the requirements of Regulation 7 (1) perform as originally intended, thereby continuing to effectively prevent or adequately control exposure. The nature and content of the thorough examination and test depend on the particular engineering controls under consideration and the nature and degree of risk posed by the hazardous substance. VIII. Monitoring Exposures Monitoring of exposure should be carried out when it is required to ensure that exposure is adequately controlled. It is required when failure or deterioration of the control measure could result in a serious risk to health or where it is necessary to demonstrate that a MEL or OES is not exceeded. A record should be kept showing when the monitoring was done, what monitoring procedures were adopted and what the results were. IX. Health Surveillance Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 34 Where it is appropriate for the protection of the health of employees the employer should ensure that they are under suitable health surveillance. Health surveillance should be treated as being appropriate where the employee is exposed to one of the substances in Section 81- 86 or Hazard group 3, 4 (biology section). It is also appropriate where the exposure of the employee is such that an identifiable disease or adverse health effect may be related to the exposure, there is a reasonable likelihood that the disease or effect may occur under the particular conditions of work, and there are valid techniques for detecting signs of the disease or the effect. Any judgement as to the likelihood that a disease or adverse health effect may occur must be related to the nature and degree of exposure. If, following an assessment, it can be shown that it is most unlikely that any disease or adverse health effect will result, then exposure can be deemed not to be significant and health surveillance is not required. Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 35 Appendix 2 REPORTABLE ACCIDENTS AND DANGEROUS OCCURRENCES The following accidents and dangerous occurrences are required by law to be reported to the Health and Safety Executive within 7 days of the incident. Failure to do so is a criminal offence. The College Safety Adviser is responsible for the statutory reporting of accidents and dangerous occurrences and it is essential, therefore, that he is notified as quickly as possible after any incident which may be reportable. Reportable accidents and dangerous occurrences include: Fracture of the skull, spine or pelvis; Fracture of any bone in the arm or wrist, but not a bone in the hand; Fracture of any bone in the leg or ankle, but not a bone in the foot; Amputation of a hand or foot, or a finger, thumb or toe, or any part thereof if the joint, or any bone is completely severed; The loss of sight of an eye, a penetrating injury to an eye, or a chemical or hot metal burn to an eye; Either injury (including burns) requiring immediate medical treatment or loss of consciousness, resulting in either case from an electric shock from any electrical circuit or equipment whether or not due to direct contact; Either acute illness requiring medical treatment or loss of consciousness, resulting in either case from the absorption of any substance by inhalation, ingestion, or through the skin; Any other injury which results in the injured person being admitted into hospital for more than 24 hours, or the person injured being absent from their place of work for three or more days (Saturday and Sunday are included in this period whether they are normally worked or not); Any ignition or explosion of explosives where the ignition or explosion was not intentional; Electrical short circuit or overload accompanied by fire; Explosion or collapse of any pressure vessel where the pressure inside the vessel was above or below atmospheric pressure; The full list of reportable accidents and dangerous occurrences is contained in the Reporting of Incidents, Diseases, and Dangerous Occurrences Regulations 1985. The College Safety Adviser has a copy of these regulations available for inspection. When a reportable accident or dangerous occurrence has occurred, the site of the incident (other than for purposes of making the area safe) must not be cleared, tidied up, or in any other way disturbed until both the College and School Safety Advisers have Health and Safety Manual June 2013 School of Biological and Chemical Sciences Queen Mary University of London 36 carried out an initial investigation.
