of intent Introduction The School Health and Safety Policy contains general and specific safety arrangements to enable and assist members of the School staff and students, and visitors to comply with the University's rules and UK Health and Safety Law. It contains advice, information and some specific instructions which apply to all who work in, or visit, the School. You are required to read this booklet carefully and then to ensure that you obtain copies of other relevant health and safety information which apply to you. All new staff, research associates and research visitors must also attend a Health and Safety induction course. This course will cover University Health and Safety (H&S) and School local H&S rules. The H&S document will be available on the CEAM website for all to read. The document includes links to relevant documentation and forms relating to research work to be undertaken. It is the responsibility of academic, administrative and technical staff to ensure, as far as is reasonably practicable, their own safety and also the safety of staff, researchers, students and visitors working in the School. Policy Statement General Statement for Health, Safety and Welfare Issue The Head of School has overall responsibility for the health and safety of personnel within the school. Part 1 (General Duties, Section 2 (3) of the Health and Safety at Work Act (1974)) requires that a written statement of the Health and Safety Policy be brought to the attention of employees and all other personnel working in the School. The School of Chemical Engineering and Advanced Materials recognises and accepts its responsibilities under Part 1 (General Duties, Section 2 (1) of the Health and Safety at Work Act (1974)). This deems that that all personnel within CEAM, as far is reasonably practicable, will ensure that Health, Safety and welfare regulations are complied with, as encompassed in the Health and Safety at Work Act. There are systems integrated within the School safety procedures to ensure compliance with these responsibilities which are written into the management structure. The School further accepts and recognises its additional obligations to the health and safety of students within the School and of other users of the School facilities, as specified under Part 1 (General Duties, Section 3 & 4 of the Health and Safety at Work Act (1974)). In carrying out these statutory duties, the School will seek the advice and full co-operation of its managers, staff and students; all recognised trade unions and professional associations, as well as that of the University Safety Office. The promotion and management of the health and safety of all persons working in the School is regarded as an essential requirement of the duties of all staff. They are expected to adopt high personal standards with regard to Health and Safety matters and to transmit their standards to 1 Health and Safety Handbook School of Chemical Engineering and Advanced Materials colleagues and students. Health and Safety considerations must be given equal weight with objectives when planning any programme of work. Adequate resources of time and funding will be made available to carry out safety duties and for safety work. The School supports the concept that Health and Safety, quality and productivity in work are mutually supporting aspirations. The competence of staff and students to carry out their work safely will be assured by adequate and appropriate training and supervision. All persons working within the School must recognise that there is a clear duty on them to do everything they can to prevent injury to themselves and others, and loss to the School. Safety is everyone’s responsibility. This policy is a local statement of policy and must be read in conjunction with the University Safety Policy, any relevant Safety Policy Supplements and any other relevant Local Rules. Everyone issued with this policy will be required to acknowledge their acceptance of it by submitting a signed copy and handed in to a member of the safety committee to be retained as proof of acceptance. Acceptance of the content of this policy is a condition of working within the School. Anyone found to be consistently failing to comply with this policy may have sanctions, including (but not limited to) withdrawal of access to the building, taken against them. This Safety Policy is reviewed on an annual basis. Head of School February 2014 2 Health and Safety Handbook School of Chemical Engineering and Advanced Materials Management Arrangements for the School The Head of School has overall responsibility for all aspects of the health and safety of personnel within the School. The formulation, implementation and development of School policy is delegated by the Head of School to the Safety Committee. Health and Safety management is a core management function within the School, and receives appropriate prominence on the agenda of management meetings. Day to day monitoring of the School Health and Safety Policy, and routine advice on health and safety issues, is a responsibility of the School Safety Officers. The School’s Health and Safety Committee is established to advise the Head of School and to coordinate and assist in implementing all aspects of the Health and Safety Policy. The committee meets regularly and representatives on the committee include school staff and the school safety officers. 3 Health and Safety Handbook School of Chemical Engineering and Advanced Materials University Safety Management Hierarchy The University safety management hierarchy is reproduced from the University's Health and Safety Policy document: Highlighted in red is the Safety Management in the School of Chemical Engineering and Advanced Materials Council University Council EB University Executive Board EB Member for Safety University Safety Office Council Appointed Lay Member Responsibility of Line Management University Safety Committee Includes Student and Union representation in membership Faculty PVC Chair FSC Faculty Safety Committee School Safety Officers School Safety Committee Head of School Or Director of Institute Or Director of Service Staff and Students Staff and Students 4 Health and Safety Handbook School of Chemical Engineering and Advanced Materials School Safety Committee The School’s key tasks are to: Ensure health and safety policy and practice is suitable and sufficient in the areas under the School control Ensure that health and safety is fully integrated into School management plans Ensure suitable and sufficient resources are allocated to health and safety issues Communicate and co-operate with the Faculty, USO, other Schools, ESS and other shared building occupiers Enable staff and students in the School to effectively communicate on health and safety issues Annually report to the Faculty and University Safety Committee summarising the health and safety activities undertaken and plans for the forthcoming year monitor and report compliance, incidents and defects (as necessary) on any health and safety or related matters (including building maintenance issues) relating to areas in their control or shared space under their control The Head of School holds personal responsibility for ensuring that the School is run in a safe manner and is supported by School Safety Officers and other trained persons as necessary to advise, monitor and plan for safe activities without undue risks to health Where more than one School occupies a building they are required to co-operate with each other for those aspects that require a building overview (such as fire evacuation) School Safety Health and Safety for Principal Investigators, Managers and Supervisors (PIMS) All Principal Investigators, Managers and Supervisors within the School should attend the training course ‘Health and Safety for Principal Investigators, Managers and Supervisors’ which is provided by the University Safety Office or an equivalent ISOH course. The training gives a good grounding in Health and Safety Legislation, University Systems and Responsibilities, Health and Safety Management, Risk Assessment, Training and Accidents. Follow the link below to book your place on one of these courses. http://www.safety.ncl.ac.uk/training.aspx Staff/Researchers Training All members of staff and researches are required to attend general safety courses and specific safety courses related to their research activities. Staff will also be expected to attend refresher training for specific courses at recommended intervals. University Training courses are advertised on their website: http://www.safety.ncl.ac.uk/training.aspx Safety Related Documents Safety related documents are kept in a secure filing cabinet in Millennium Laboratory (C324) office and are available to relevant persons for inspection on request to the Safety Officers or a member of the Safety Committee. In house Health and Safety Training is also delivered via a Health and Safety Induction Course. This course covers both university regulations and local regulations. 5 Health and Safety Handbook School of Chemical Engineering and Advanced Materials Incidents and Near Misses The School has a duty to investigate incidents (including accidents and near misses). These should be reported to the University Safety Office (USO) using the forms available on their website: http://www.safety.ncl.ac.uk/accidentfireandemergency.aspx At School level, each laboratory has a book for the reporting of incidents or near misses. These books are reviewed on a regular basis and reported back to the safety committee for review and subsequent remedial action to be taken if necessary. 6 Health and Safety Handbook School of Chemical Engineering and Advanced Materials Statement of roles of key members of staff Head of School The Head of School has overall responsibility for all aspects of the health and safety of personnel within the School. The formulation, implementation and development of School policy is a responsibility delegated by the Head of School. School Safety Officers School Safety Officers are appointed by the Head of School. The School Safety Officer role is principally to advise the Head of School on all aspects of health, safety and welfare within the School. To make this task manageable there are additional appointments that can be made including; Deputy School Safety Officers, Biological Safety Supervisors, and Radiation Protection Supervisors. This role may include the management of local procedures and School self-inspection, and undertaking review of School Safety Policies and Local Rules. School Safety Officers are expected to assist the USO in carrying out safety audits and inspections, and to undertake basic investigations of incidents and record their findings. Safety tasks related to individual projects would normally be carried out by the Principal Investigator concerned rather than the SSO, though the latter will be in a position to offer advice or to know where such advice might be sought. The Safety Officers will also liaise with other safety personnel in the School about risks involved within their specific discipline i.e. Biological Safety Supervisor. School Safety Committee The aim of the Safety Committee is to advise the Head of School of safety issues arising within the School and to implement the University Safety Policy. Mr S Latimer (Chair) (Superintendent) (Merz Court) Mr R J Dixon (Deputy Chair) (Laboratory Supervisor) (Merz Court) Professor A Wright (Safety Officer) (Merz Court) Dr E A Charles (Safety Officer) (Herschel / Bedson Building) Mr P Sterling (laboratory Manager) (Merz Court) Mr Simon Daley (Electrical/Electronics Supervisor) (Merz Court) Manual Handling Co-ordinators The manual handling co-ordinator for the School is Mr Stewart Latimer (Stewart.Latimer@ncl.ac.uk). He will give training on manual handling and will assess all tasks that require any significant degree of lifting and movement. Display Screen Assessor Display Screen Assessment will be carried out by the Information Technology Officer or another trained DSE assessor. Portable Appliance Testing (PAT Testing) Wiring, servicing or testing of portable appliances may only be carried out by those with a sufficient level of experience and technical knowledge. All mains powered electrical equipment used at the University is required to be subject to examination and testing both periodically and before the equipment is bought into service. 7 Health and Safety Handbook School of Chemical Engineering and Advanced Materials For all portable appliances (things with plugs) it is the responsibility of the School or Service to ensure that examination and testing is undertaken. Personal equipment used on site may also be examined and tested and action taken should any defects be found. Records must be maintained for PAT testing undertaken. Further information and guidance is available at www.safety.ncl.ac.uk/electricalsafety.aspx Portable Appliance testing is undertaken by Mr Stewart Latimer, Mr Paul Sterling, Mr Iain Ditchburn,(Merz Court) and Mr Neville Dickman and Mr Chris Dunn (Bedson Building) or another trained PAT assessor. First Aiders The School has four first aiders Merz Court Building Mr Rob Dixon (Laboratory Supervisor), Mr Iain Ditchburn Herschel / Bedson Building Mr Chris Dunn, Dr Isabel Arce-Garcia For immediate medical treatment of "walking wounded" for more than superficial injury and any exposure to chemicals go, or take the victim, directly to the Minor Injuries Unit of the A&E of the RVI. For more serious injury or in cases of any doubt CALL AN AMBULANCE. University Safety Office Advisors The University Safety Office provides general advice on health and safety. It also has specialists who give advice and guidance in specific areas, for example Radiation Protection (UV, Laser etc), Biological Protection, Fire Safety and Occupational Health. Contact details for specialist advisors are available from the University Safety Office web site. http://safety.ncl.ac.uk/contacts.aspx 8 Health and Safety Handbook School of Chemical Engineering and Advanced Materials Specific Issues Emergency Procedures Emergencies Emergency Contact Numbers In the first instance call University Security Office Dial ext 6817 (Security.control@ncl.ac.uk) for FIRE - POLICE – AMBULANCE Dial Internal 6666 [if no response, dial External 9-999] If unsuccessful with above, use emergency Red Telephone outside the Students Common Room on the ground floor, (up from the Porters Lodge) which is connected directly to the House Services Office. Accidents All accidents (including incidents not involving injury) and "near misses" must be reported. The reporting procedure is in two parts, (i) (ii) informing a responsible person to take control of the incident and completion of an official accident report. The following must be informed of accidents as soon as is reasonably practicable: School Safety Officers Supervisor(s) or Research group leader Workshop Supervisor School First Aiders If the above are not available the accident must be reported to a member of academic staff as soon as possible and to the above when they become available. The member of staff assuming control must ensure that an Accident Report form is completed. The form is available on the University Web Site address; http://www.ncl.ac.uk/internal/safety/acc-form.html Copies are then automatically cascaded to: The School Safety Officers The Head of School The person submitting the form The accident will be investigated by the School Safety Officers and other staff if deemed necessary, all persons involved may be required to write down the details of the incident and this information will then form part of the official report to the University Safety Officer. All incidents involving carcinogens must also be reported to the University Potent Carcinogens Officer. Ill-health that is believed to be work-related (including stress) should be reported using the accident report book. Confidential matters may be taken up with the University Safety Officer directly. 9 Health and Safety Handbook School of Chemical Engineering and Advanced Materials Fire Safety Fire 1 Typical fire alarm break point In the event of fire Sound the alarm Report to the Fire Marshal based at the Fire Assembly Point based at the entrance to the building. On hearing the alarm, leave the building immediately, but calmly, using the nearest fire exit. Close all doors behind you. Do not use the lifts. Do not search for the seat of the fire or for the cause of the alarm sounding. Go to the Fire Assembly Point, immediately outside the Old Library Building (Merz Court) or the car park (Bedson Building). 2 Assembly point (Merz Court) On hearing the alarm, the Fire Marshal, or his deputy will Ring 6666 to summon the Fire Brigade without delay unless informed by the wardens that there is no fire or other emergency. On hearing the alarm, the Fire Wardens, or their deputies will check their assigned areas to ensure that everyone has left. Report to the Fire Marshal, who will be stationed outside the main entrance, next to the Fire alarm Panel in Main Foyer. Wardens who are in a location remote from their assigned areas should leave the building immediately and not attempt to carry out their duty. Such wardens should inform the Fire Marshal that they were not able to assist with the evacuation of the area assigned to them. On hearing the alarm, the Head of School or the acting Head of School will: Take up station next to the Fire Marshal. Check whether the Fire Brigade has been summoned. On hearing the alarm, the Fire Marshal will take up station next to the Fire alarm Panel in Main Foyer. In the event of the absence of all the above staff; the first member of staff to reach the reporting point should assume responsibility until relieved. On being given the all clear by the Senior Officer of any Emergency Service present, the Fire marshal or Staff member who has assumed control will give instructions to return to the building, or parts of it, when it is safe to do so. Fire / Evacuation Wardens (Appendix 1, page 25) It is the duty of the Fire Wardens to check their assigned areas (laboratories, offices, etc.), to ensure that everyone has left and then report to the Fire Marshal who will be who will be stationed outside the main 10 Health and Safety Handbook School of Chemical Engineering and Advanced Materials entrance. The persons named in brackets will deputise in the absence of the Warden. In the absence of both any member of staff in the area should report. The Fire alarm is tested every Tuesday morning at approximately 8-30am, it will sound for approximately 30 seconds. Fire Outside Normal Working Hours (5.30 pm - 8.00 am, weekends and holidays) In the event of Fire; Sound the alarm. Call Security [6666 or use the Red Telephone outside the Students Common Room on the ground floor, (up from the Porters Lodge) which is connected directly to the House Services Office]. Follow normal evacuation procedures and report to whoever takes control. Fire extinguishers Fire extinguishers are sited in strategic positions outside of laboratories and all laboratories have fire blankets. Everyone should know the location of firefighting equipment in their work areas. Fire Safety Training courses are held by the University Safety Office; http://safety.ncl.ac.uk/training.aspx Foam Use on general fires (paper, cloth, wood), oil and highly flammable liquids DO NOT USE on live electrical equipment Carbon dioxide Produces a high pressure stream of carbon dioxide gas which should be directed at the base of the fire. A general purpose extinguisher for laboratory use and for electrical fires. Ineffective against alkali metals. 11 Health and Safety Handbook School of Chemical Engineering and Advanced Materials Fire blanket Effective at smothering clothing fires, oil baths etc Personal Emergency Evacuation Plan (PEEP) The Personal Emergency Evacuation Plan (PEEP) is one part of the reasonable adjustment arrangements made by the University to include disabled staff and students in all aspects of working or studying at the University (where this is reasonably practicable). This includes emergency egress during out of hours working as well as during normal hours. Responsibilities Disabled Member of Staff or Student The individual must inform the University on appointment if they need assistance in an emergency and be involved in discussions about how their needs will be met. If anyone at the University considers that a disabled person needs assistance or observes that someone has mobility difficulties then they should discuss this with Human Resources (staff) who will call an anonymous case conference if the situation is not already in hand. School Safety Officers It is the responsibility of the School Safety Officers (SSO) to coordinate the PEEP for both staff and students. The SSO should be familiar with the existing fire arrangements for the building and be able to identify staff to assist in any evacuation. Evacuation chairs are located on alternate landings on the stairs and trained evac chair operators are available. The PEEP co-ordinator should also liaise with School Safety Officers in other buildings where applicable and should follow up with any timetabling issues with the School Manager. In the case of students the SSO should also report back to the Head of School. It is the responsibility of the School to distribute the PEEP. Full guidance on PEEP can be found on the USO website at the following address:- http://safety.ncl.ac.uk/forms.aspx 12 Health and Safety Handbook School of Chemical Engineering and Advanced Materials General Risk Assessment The process of Risk Assessment is at the heart of the control of risks at the University. In many places in this policy a requirement for a risk assessment is stated. In these cases a specific risk assessment will be needed to deal with the issue concerned. However it is commonly practicable to combine issues (making a combined risk assessment) or have generic risk assessments for a specific topic provided that the assessment remains ‘suitable and sufficient’ for the work to be undertaken. (See www.safety.ncl.ac.uk/riskassessment.aspx for more information.) It is therefore University Policy that all aspects of work where a significant hazard exists are subject to risk assessments that are suitable and sufficient to identify the risks concerned, the persons who are at risk, the proper control measures needed and the correct means of ensuring that those controls are put into place, monitored and any deviations followed up. Electrical Safety Only electrical equipment which has a current Portable Appliance Testing (PAT) sticker may be used in any area of the School. PAT (Portable Appliance Testing) should be carried out on any new equipment before it can be used, and existing equipment must have an up to date PAT sticker before being used. Any equipment with an out of date PAT test labels must not be used, and should be reported to the appropriate trained PAT testers for testing. These are Mr Stewart Latimer, Mr Paul Sterling, and Mr Iain Ditchburn (Merz Court), Mr Neville Dickman and Mr Chris Dunn (Herschel/Bedson Buildings) or any other suitably PAT qualified technician. Electrical apparatus must be suitably fused and maintained with the help of the Electrical/Electronics Supervisor (Mr Simon Daley – Merz Court) or another qualified electrical technician. Electrical flex on any apparatus should be carefully examined before each use to ensure no damage has occurred that could expose live wires. Check that any plug you use is securely attached to the flex by the retaining screws or clamps. All electrical repairs must only be carried out by the Electrical/Electronics Supervisor or another qualified electrical technician. No wiring of anything electrical/electronic must be carried out by anyone except the Electrical/Electronics Supervisor or another qualified electrical technician. Any equipment with broken plugs/connectors must not be used and should be reported to the Electrical/Electronics Supervisor or another qualified electrical technician for repair If any damage is evident on any electrical equipment, under no circumstances must equipment be switched on. The problem should be reported immediately to a member of the technical staff, and any repairs will be carried out as required by the Electrical/Electronics Supervisor or another qualified electrical technician. Any spillage of liquids on or around any electrical equipment must be reported to a member of the technical staff. If an EARTH cable exists with any heating tape, process heater or heating element, it MUST be connected to the appropriate connection point. If in doubt ask the Electrical/Electronics Supervisor or another qualified electrical technician. No mains plugs should be fitted by anyone other than the Electrical/Electronics Supervisor or another qualified electrical technician. 13 Health and Safety Handbook School of Chemical Engineering and Advanced Materials Field Trips The University Safety Policy Supplement on field trips provides more detail and guidance on organising and managing trips. Guidance is also available from UCEA / USHA (see www.ucea.ac.uk/en/Publications/Health_and_Safety.cfm ) A British Standard that should be complied with wherever appropriate. http://safety.ncl.ac.uk/pol-sups.aspx First Aid Provision All Laboratories have a First Aid Box. Eye Wash Bottles Eye Wash Sprays over a sink are available The first aiders as previously referred to in the document under First Aiders. 14 Health and Safety Handbook School of Chemical Engineering and Advanced Materials Laboratory Safety – Teaching and Research Most laboratories are either research or teaching labs. Some laboratories are used for teaching and research. The same safety measures are applicable to both uses. No research work is to be carried out when laboratories are in use for teaching. All students, postgraduates, researchers and staff must wear appropriate safety clothes when working in laboratories. Laboratory coats / protective gloves and other protective equipment must not be worn outside of laboratory areas. Visitors must be equipped with the appropriate safety equipment when visiting the laboratories. No food or drink or to be consumed in the laboratories. All accidents must be reported to Technical staff. All faults must be reported to Technical staff. COSHH forms must be situated next to the experiment and copies must be given to the Laboratory Supervisor and one kept by the researcher before commencement of the experiment. Unattended Experiment Forms must be completed before out of hours experiments begin. http://www.ncl.ac.uk/ceam/about/Safety.htm All bottles and containers must be suitably labelled. Volumetric Flasks used for making up stock solutions must not be used for storing solutions. Movement of Winchesters (2.5L bottles) must be done using a bottle carrier. Movement of chemicals/apparatus should be transported in suitable carrying trays Wear appropriate safety clothing when transporting chemicals. If unavoidable when transporting chemicals/apparatus from laboratory to laboratory wear one glove only and open the doors with the ungloved hand. No equipment or chemicals are to be removed from the laboratories without prior permission of the Technical staff or the researchers in charge of the project. Dispose of waste chemicals in the designated containers (following instructions on the laboratory notice board). These instructions are reviewed annually or if any situation arises that is not addressed by these criteria. Inform the technicians when these containers are full and they will then transport them ready for disposal. The Good Chemical Practice Guide is a document that underpins good laboratory practices. The Good Chemical Practice Guide is given out in Health and Safety Induction Courses and is also available on the School Safety Website. (see Appendix 2, pages 26-29) Risk Assessments COSHH (Chemicals) assessment includes Material Safety Data Sheets (MSDS) A copy will accompany a chemical when it is delivered from the supplier. If it is not included it can be obtained from chemical supplier’s website. Personal Protective Equipment (PPE) Standard protective equipment for laboratory work is a laboratory coat, safety glasses and gloves. Additional PPE must be identified when carrying out the COSHH assessment. Potent Carcinogens 15 Health and Safety Handbook School of Chemical Engineering and Advanced Materials Any chemical with CHIP classification must be registered with the University Safety Office before it may be ordered or used. http://safety.ncl.ac.uk/carcinogenregistration.aspx CHIP carcinogen classification system Category Definition Carc. Cat. 1 Substances known to be carcinogenic to man. Carc. Cat. 2 Substances which should be regarded as if they are carcinogenic to man. Carc. Cat. 3 Substances which cause concern due to possible carcinogenic effects. CHIP carcinogen classifications will be written in MSDS precisely as "Carc. Cat." followed by the rating of 1, 2 or 3. The Carc. Cat rating will normally be in the same section as the Risk phrases (R phrases) e.g. R45 or R49. All carcinogens should be assigned into the above categories on the registration form. A new chemical classification system called CLP / GHS is currently being implemented worldwide. This system classifies carcinogens as follows: CLP / GHS carcinogen classification system Category Definition Category 1A Chemicals known to have carcinogenic potential for humans Category 1B Chemicals presumed to have carcinogenic potential for humans Category 2 Suspected human carcinogens Safe handling, storage and disposal of chemicals Instructions are given out in the Health and Safety induction session. There is also a PowerPoint presentation on the School Safety website. COSHH Risk Assessment http://safety.ncl.ac.uk/forms.aspx Anyone who uses or intends to use chemicals should complete a COSHH assessment form. Under the Control of Substances Hazardous to Health (COSHH) Regulations (2002) a risk assessment must be made before hazardous chemicals may be used or purchased. The way the forms are completed will vary from one project/experiment to another. In some cases a single form will suffice for a project (when it consists of a series of very similar experiments), whilst for others a form needs to be completed for most experiments. If the risks for a series of experiments are the same then it is acceptable to refer to previous assessments. The Supervisor(s) of a research worker, technician, undergraduate project student, etc. or the principal investigator of a research group should discuss the contents of the form and sign it before the project/experiment commences. The date for review should be carefully set to ensure proper supervision and in any case must not be more than 5 years. For "one-off' experiments this should be indicated in the review date box. Experiments which are not ‘one off’ but are continually changing, the COSHH assessment must be regularly brought up to date. If experiments are not changing on a continuous basis then the COSHH form must be reviewed and their Supervisor sign and date the revised form. Three copies of the COSHH form should be produced; 16 Health and Safety Handbook School of Chemical Engineering and Advanced Materials One placed next to or near the experiment/rig. One passed to the Laboratory Supervisor. One held by the researcher. The responsibility of this process is with the researcher and then the Supervisor. The COSHH form must be signed by the Supervisor(s) (or a nominated substitute). Safety inspections will include the monitoring of the working of this scheme. The use of particularly dangerous chemicals may be further restricted by UK, University, and/or School rules. Chemicals with unknown hazards should be treated with great caution. Some assessment may often be made from knowledge of similar compounds. Training will be given to researchers on how to complete the forms and instruction are also on the School Safety Website. BIOCOSHH A separate School induction session is presented to Researchers working in the Biotechnology laboratory. This will enhance the general School H&S induction session given to all Academics, Postgraduates and researchers. http://safety.ncl.ac.uk/forms.aspx Waste Disposal Chemicals Disposal of chemical waste should be addressed during the COSHH risk assessment. Members of staff who sanction the purchase of chemicals are responsible for their safe storage, use and disposal. Each laboratory, group or Section (as appropriate) should establish a system for dealing with chemical waste along the following lines: Separate containers should be used for different types of waste. Waste should be properly labelled, the label should indicate the type of waste, the origin and volume, concentration (e.g. lab C317), and the date the container was brought into use. Waste which is highly flammable must be kept in fire resistant bins. Waste should be disposed of promptly (within 3 months, or less for some waste. If in doubt seek advice from the School Safety Officer). The Laboratory Supervisor/Technicians are responsible for organising the collection and disposal of chemical waste from laboratories. Anything (paper, cloths, gloves etc.) that is contaminated with chemicals must be treated as hazardous chemical waste and placed in container with the correct labelling. Drains must not be used for the disposal of chemical waste. The majority of materials are not suitable for disposal by this route and to do so would contravene the requirements of the Water Authority. It is understood that trace amounts of organic and inorganic substances may remain in aqueous washings, which can be flushed down the drains, but all reasonable steps should be taken to minimise these quantities and to ensure that effective dilution takes place. Clinical Laboratories designated for the use of bio-hazardous material must have specific protocols for the collection and disposal of waste, with arrangements approved by the University Safety Office. 17 Health and Safety Handbook School of Chemical Engineering and Advanced Materials Disposables and sharps* Laboratory disposables (plastics, gloves, etc.) and sharps (needles, scalpels, etc.) must be placed in the appropriately labelled containers, provided in research group areas and teaching laboratories, for disposal. Such disposal is arranged by the Laboratory Technicians. Electrical* Small pieces of electronic/electrical equipment should be placed in the blue container. When it is full request it to be emptied by one of the Technical staff. If the piece is too large for the container, ask for assistance from one of the Laboratory Technical staff on how to dispose of it. Glass * Thoroughly cleaned and unlabelled laboratory waste glass should be placed in appropriate glass bins for disposal. Each group/laboratory should identify someone who will be responsible for ensuring that this system is operated in their area. Metals* Metal containers (e.g. secondary packaging) should have labels removed or obscured and be placed in the blue container in each laboratory. When it is full request it to be emptied by one of the Technical staff. If the piece is too large for the container, ask for assistance from one of the Technical staff on how to dispose of it. *Instructions on how to dispose of waste (Appendix 3, page 30-33) Compressed Gases Gas Cylinders Compressed gases are only to be used from safely clamped cylinders, which should be located away from doors and stores of chemicals or solvents. Permanent apparatus dependent on such gas supplies should be connected with leak-proof gas lines. Suitable precautions should be taken for the use of other gases (e.g. from small cylinders) and these must be kept away from corrosive sources in a well-ventilated place, or in a fume cupboard if at all toxic. Academic Staff who obtain special gases must supervise their use and arrange the disposal of waste gas and empty cylinders. All gas cylinders are kept in a secure store with access restricted to authorised technical staff, all gas cylinders removed from this store are logged by the technical staff. Safe use of gas cylinders When transporting gas cylinders always use the correct trolley and ensure the cylinder is secured with the trolley chains. Upon reaching the required location the cylinder should be properly secured to a wall or table with a clamp or chain and the trolley returned to the store. The gas cylinders are fitted with valve protection caps or guards that need to be removed before a regulator can be fitted. A member of the technical staff will fit the regulator to the gas cylinder checking both the condition of the regulator and the cylinder; he will then carry out a gas leakage test. If at any time a gas leak is detected inform a member of the technical staff immediately. Safe gas cylinder handling and usage is demonstrated in the H&S induction course. 18 Health and Safety Handbook School of Chemical Engineering and Advanced Materials Manual Handling Risk assessments (laboratories, offices, workshops, etc.) should take manual handling into consideration. Advice and guidelines about moving heavy objects can be obtained from the School’s Manual Handling Coordinator. The following items of manual handling equipment are available to assist; potential users must obtain permission and instruction from the manual handling coordinator. Mobile Phones Mobile phones and Ipads must not be used in any laboratory areas. Computers & Laptops Where it is necessary to use a laptop or computer in a laboratory a disposable second skin should be fitted to the keyboard. Risk Assessment This Risk Assessment differs from the COSHH assessment in its nature as it is for equipment and physical risks e.g. pressurized system, moving machinery, heat and written protocols where necessary are some of the examples. To obtain the form go to the USO website; http://safety.ncl.ac.uk/forms.aspx Training will be given to researchers on how to complete the forms and instruction will also be on the School Safety Website. 19 Health and Safety Handbook School of Chemical Engineering and Advanced Materials Out of Hours Working The University Health and Safety 2012 policy document gives detailed instructions relating to 'Work Outside Normal Hours' (USO website: Policy Supplement – http://www.safety.ncl.ac.uk/pol-sups.aspx ) which must be adhered to. In addition, the School Out Of Hours Working Policy which, is subject to monitoring and review for work outside normal hours is given below. For the purposes of this policy 'work outside normal hours' refers to working in the School outside the hours Monday - Friday 8.00 am – 6:00 pm (workdays) and at weekends and University holidays. No student may work outside normal hours without permission of the Head of School. For postgraduates, permission is automatically given provided the permission to work agreement has been completed. Only the main entrance and courtyard entrance are open during working hours. All other outer doors are closed. At weekends, during holidays and after 5.00 pm on weekdays the courtyard entrance door will also be closed. Outside of hours swipe-card access to the Merz Court and Bedson Building may be granted on a case-by-case basis.

June 2013 25 Health and Safety Handbook School of Chemical Engineering and Advanced Materials APPENDIX 2 GOOD CHEMICAL PRACTICE (GCP) 'Good Chemical Practice' relates to the safe use of chemicals in laboratories: it does not apply to any other situation. It defines a MINIMUM acceptable standard for work with ALL laboratory chemicals. For SOME laboratory chemicals no other precautions will be necessary. School Safety Policy and Arrangements. Three principles underlie this document:1) The quantities of chemicals in use at any one time are small. 2) Use and access are restricted to competent people or to staff or students undergoing a planned and supervised learning process. These people have learned, or are learning, the principles of good chemical practice (GCP). 3) The laboratory is a controlled working environment with a number of special features designed and provided for users of chemicals. Competence and Supervision Chemicals may only be used by individuals with a sufficient level of competence with an appropriate level of supervision. This document is not a training manual and may not be used as a substitute for this requirement. Introduction The aim of ‘Good Chemical Practice' is the protection of people against hazardous substances encountered at work in laboratories by appropriate means of control. The underlying fundamental principle is Contact with chemicals must be avoided by the use of appropriate control measures. Laboratory Design 1. The laboratory should be easy to clean. 2. Bench surfaces should be impervious to water and resistant to chemicals. 3. The laboratory should meet published design standards. Mechanical ventilation, if available, should operate by extracting air from the laboratory to atmosphere outside the building in such a manner that reentry of the discharged air is unlikely. Working Methods 4. A COSHH risk assessment should be completed prior to research work beginning and displayed as close as possible to the experiment being undertaken. 5. Smoking, eating, drinking, use of mobile phones and the application of cosmetics are prohibited in areas where chemical substances are used or kept. 6. Food, drink etc can readily become contaminated if kept and used alongside chemical substances. It is then possible to transfer dangerous substances to the mouth or other sensitive areas of the face. 26 Health and Safety Handbook School of Chemical Engineering and Advanced Materials 7. Inhalation of vapours or skin contact with any substance is to be avoided. In general terms, fume cupboards must be used for substances which are toxic by the inhalation route even though a written COSHH risk assessment may not be required (e.g. substances allocated the risk phrases R23 -'Toxic by inhalation') 8. Work must be performed cleanly with the minimum of spilling and splashing in order to limit contamination. Suitable dispensing aids must be used and substances handled over spill trays, where appropriate. 9. Bench tops and laboratory equipment must be cleaned as soon as practicable after use. 10. Contaminated surfaces and equipment must be cleaned without delay. 11. Exposure to gases and vapours should be limited by covering vessels, prompt replacement of caps and stoppers to bottles and, if possible, the handling of volatile, gaseous or dusty substances in closed systems. 12. The work area should be kept tidy and substances should be put in approved storage enclosures when not in use. 13. Bottles, especially Winchester size, should be transported in special carriers. 14. The correct handling equipment should be used to transport and manipulate cans and drums. 15. The procedures for unattended experiments should be observed, and the forms kept up-to-date. 16. The appropriate equipment must be available for prompt clean-up and decontamination after spills. 17. Work which requires personal control should never be left unattended. 18. Flames and compressed gas supplies should be shut off when not in use and on leaving the laboratory. 19. The limitations on late and on lone working may be found in the University Safety Policy. Additional restrictions may be imposed by departmental local rules. 20. Hands should be washed before leaving the laboratory. Containers and Storage 21. Containers must be properly labelled. 22. Chemicals not in use should be returned promptly to their correct storage enclosures. 23. Light sensitive substances (e.g. chlorinated solvents) should be stored in amber-coloured bottles away from the light. 24. It is prudent to keep all chemicals out of direct sunlight 25. Surplus materials should not be allowed to accumulate in laboratories. Spillage 26. Sufficient detailed information concerning the chemicals, including methods for dealing with spillage, should be readily available. Individuals should be aware of the hazards of the materials they are using, and familiar with spillage procedures. Waste (Refer to PowerPoint presentation on the School website) 27. Waste receptacles should be covered, labelled, and not overfilled. 27 Health and Safety Handbook School of Chemical Engineering and Advanced Materials 28. Incompatible wastes (e.g. halogenated and non-halogenated solvents) should be kept apart, with particular care to separate the disposal/storage of acetone and chloroform. 29. Disposal should take place in accordance with School/University procedures, at the earliest opportunity. In no case should they be left for the unsuspecting to inherit. Personal Protective Equipment 30. Using personal protective equipment is not a substitute for other control measures. The purpose of personal protection is normally to prevent accidental exposure to hazardous substances. It is always necessary to match the type of protection (e.g. glove material) to the particular substance, but this is especially important if likely exposure is to be longer than accidental or, of course, if the risk to health from exposure is very high. 31. Laboratory Coats. Personal clothing must be protected from contamination by a suitable laboratory coat or overall which should be changed before becoming excessively soiled. If protective clothing is liable to become heavily contaminated, a heavy-duty plastic or rubber apron should also be worn. 32. Gloves: Wear suitable protective gloves to avoid hand contact, or the longer sleeved type if the arms are also at risk of contact with the substance. 33. Gloves should be suitable for the material being used. This information is provided by the supplier. If in doubt ask your supervisor or your School Safety Officer. 34. Gloves should be checked for holes before use. 35. Before removal, gloves should be washed in warm detergent solution (preceded by a specific cleansing agent, if necessary). 36. Suitable eye protection should be worn at all times in laboratories where the handling of chemicals is the predominant work. 37. Safety spectacles must be worn to protect the eyes from splashes when liquids are being handled. However, if the work may generate fumes, mists, dust clouds or heavy splashing then suitable goggles or a face shield should be worn. 38. Masks and respirators: Since the principal method for the control of airborne hazards is to contain the substance, respiratory protection should only be necessary in emergency situations. Filter-type respirators do not have universal applicability so that it is always necessary to match the filter to the substance. Information on suitability is available from the suppliers. If in doubt ask your Supervisor or School Safety Officers. Accidents 39. Any personal contact with a substance should be dealt with immediately by safe and effective decontamination. 40. All accidents must be reported using http://safety.ncl.ac.uk/forms.aspx 41. Near misses should also be reported. 28 the University Accident Report Form Health and Safety Handbook School of Chemical Engineering and Advanced Materials Glass and Sharps 42. Many laboratory accidents arise from the handling of glassware and sharp objects. Such injuries may provide a ready means for toxic substances and biological materials to enter the body, and should be treated immediately. 43. Detergents should be employed as the normal means of cleaning glassware. 44. Cleaning techniques involving oxidising agents merit an individual risk assessment. 45. Glass and sharps must be disposed of into the relevant containers. Highly Flammable Liquids 46. Vapours from highly flammable liquids are denser than air and thus tend to sink to ground level where they can spread, undetected, over a large area. IT IS ESSENTIAL TO MINIMISE THE PRODUCTION OF SUCH VAPOURS AND THE ASSOCIATED RISK OF IGNITION BY FLASHBACK FROM A REMOTE SOURCE. 47. Fire and explosion can occur when vapours are mixed with oxygen or air in proportions that lie between the Lower and Upper Explosive Limits (LEL and UEL respectively). For most solvents the LEL is between 1% and 5% in air, and therefore good ventilation is necessary for fire safety as well as control of toxic hazards. 48. Some substances (e.g. certain ethers and aldehydes, carbon disulphide) can be ignited at temperatures produced by hot plates and ovens. Carbon disulphide, for instance has an auto-ignition temperature only just above 100C. Static electricity (which may be generated by liquids flowing through pipes or by pouring) is a possible source of ignition to any highly flammable liquid, as is any electrical fitting capable of sparking. 49. Highly flammable liquids should be stored in sealed containers in fire resisting enclosures. 50. Quantities should be kept to a minimum and the aggregate quantity should not exceed 50 litres in any laboratory. 51. They must not be stored in refrigerators and freezers unless expressly designed for the purpose (units with internal lights, in general, are not). Unsuitable refrigerators and freezers should carry the standard warning label. 52. Flammable substances must be kept well away from sources of ignition including naked flames, electric hot plates and non-flameproof electrical equipment. 53. Do not overheat substances with low auto-ignition temperatures, or allow their vapours to come into contact with hot surfaces. 54. Bulk dispensing must only be carried out by trained staff in a safe area. 55. Highly flammable liquids must not be poured down the sink. 56. Special risks exist during heating under reflux and distillation. Departmental Safety procedures should cover such points as safe heating methods and the level of attendance during the procedure. 29 Health and Safety Handbook School of Chemical Engineering and Advanced Materials APPENDIX 3 BROKEN/WASTE GLASSWARE Chemical Containers Organic (solvents) Glassware (Broken/Waste) Inorganic (solutions) Inorganic/Organic Solids Dry/clean wherever possible Place into waste glass container Remove top and clean and dry, place Remove top and clean and dry, place into lab plastics recycling bin into lab plastics recycling bin Vent container in fume cupboard to Remove any residual chemical(s) remove any residual chemical(s) Rinse and dry container Rinse and dry container Remove/disfigure label Remove/disfigure label Place into waste glass bin Place into waste glass bin If>2.5l store until sufficient quantity If>2.5l store until sufficient quantity accumulated and request removal by accumulated and request removal by Laboratory Staff Laboratory Staff If <1l place into waste glass container If <1l place into waste glass container When bin full request removal by Laboratory Staff IF HEAVILY CONTAMINATED SEEK ADVICE FROM LABORATORY TECHNICAL STAFF PRIOR TO DISPOSAL 30 Health and Safety Handbook School of Chemical Engineering and Advanced Materials WASTE LABORATORY PLASTIC Chemical Containers Organic (solvents) cuvettes General Laboratory Waste Inorganic (solutions) Inorganic/Organic Solids Any other waste e.g. Place into plastic recycling bin Vent container in Remove any residual chemical(s) Remove any residual chemical(s) (see photo of contaminated waste) fume cupboard to remove any residual chemical(s) Rinse and dry container + Lid Rinse and dry container + Lid Rinse and dry container + Lid Remove/disfigure label Remove/disfigure label Place into plastic recycling bin Place into plastic recycling bin Remove/disfigure label Place into plastic recycling bin When bin full request removal by Laboratory Staff IF HEAVILY CONTAMINATED SEEK ADVICE FROM LABORATORY TECHNICAL STAFF PRIOR TO DISPOSAL 31 Health and Safety Handbook School of Chemical Engineering and Advanced Materials SHARPS WASTE Syringes Hypodermic needles Cutting blades e.g. scalpel blades Tips from automatic pipettes Biological waste (do not close lid prior to autoclaving) Do not fill above the line indicated on the bin.
