The University of Leeds Health and Safety Policy [4] sets out • the University’s aims and objectives for the management of health and safety; • outlines the organisation and arrangements for putting it into effect; and • also outlines the arrangements for monitoring the policy. The University Health and Safety Services website [3] provides detailed information on specific topics. For individual groups, students, senior managers, specialists, staff, principal investigators, there are separate lists of the most relevant topics. While parts of this handbook reproduce University Health and Safety Services information this handbook aims to • describe the health and safety management functions and responsibilities which are delegated to departmental staff; • define and explain the safety procedures and rules which do exist within the School; • to provide the health and safety information which is specific to the School of Physics and Astronomy. 1 2 CHAPTER 1.

Undergraduate students (UG), postgraduates (PG), postdocs (PDRA). 1.2 Functions and Responsibilities (Prof Bryan Hickey) 1.2.1 Students The University Safety Policy [4] draws the attention of all students of the University of Leeds to their legal responsibility, under section 8 of the Health and Safety at Work etc. Act 1974, not to interfere with or misuse anything, any objects, structures or systems of work, provided by the University of Leeds in the interests of health and safety. Students should • report any accident at work which results in personal injury or ill health, however minor, and every dangerous occurrence, including fire, using the approved reporting mechanisms; • report ”near miss” incidents which have the potential to cause injury or ill health, using the approved form; • notify the Head of Health and Safety Services when suffering from a disease or medical condition which may be caused by, or made worse by, work activities (this information will be treated as confidential); • not proceed with any activity if they feel it poses a threat to their health and safety, or to that of others; • report any unsafe or unhealthy working conditions, or suspected faults in buildings, building fabric, or in any equipment, to the Head of School, without delay; • assist any visitors who may not be familiar with University procedures, to the best of their abilities. 1.2. FUNCTIONS AND RESPONSIBILITIES (PROF BRYAN HICKEY) 3 Any member of staff or any student may contact Health and Safety Services for advice and guidance. 1.2.2 Staff All staff are responsible for their own health and safety, and the health and safety of others who may be affected by their acts and omissions. All staff must ensure that they conduct their duties in a safe manner and in accordance with • the University Health and Safety Policy • any Faculty/School/Service Safety Policy or Guidance Notes • any specific codes of practice relating to particular activities • any relevant safety legislation and guidance. Staff must ensure that they • take reasonable care of themselves and have due regard for others • where necessary help the University meet the duties imposed on it • don not interfere with or misuse anything provided for health and safety • bring any breaches of the safety policy to the employer’s attention via their Line Manager or Health and Safety Manager • report any accident at work which results in personal injury or ill health, however minor, and every dangerous occurrence, including fire, using the approved reporting mechanisms • report ”near miss” incidents which have the potential to cause injury or ill health, using the approved form • notify the Head of Health and Safety Services when suffering from a disease or medical condition which may be caused by, or made worse by, work activities (this information will be treated as confidential) • not proceed with any activity if they feel it poses a threat to their health and safety, or to that of others • report any unsafe or unhealthy working conditions, or suspected faults in buildings, building fabric, or in any equipment, to the Head of School or Service, without delay • assist any visitors who may not be familiar with University procedures, to the best of their abilities. 1.2.3 Academic Supervisors (including Principal Investigators) The health and safety management of research projects and other related academic activities is usually delegated to research supervisors and group leaders. This is assumed unless an alternative arrangement is agreed with the Head of School and written down as part of the research documentation. Their duties include 4 CHAPTER 1. SAFETY MANAGEMENT • ensuring that risk assessments take place at the planning stage of any research proposal, and that the costs of implementing suitable risk control measures, and disposing of any hazardous substances or materials, are included in the funding arrangements; • ensuring that risk assessments are reviewed and kept up to date as the research proceeds, and that everybody involved in the work activity has read and understood the risk assessment; • ensuring local inductions into the work area are carried out and recorded; • ensuring that control measures such as guarding of moving parts; provision of protective equipment, are implemented and continue to be effective; • leading on the performance of risk assessments and, where appropriate, working with competent people to carry out the risk assessments for their work, ensuring those people remain competent and receive appropriate training, resource, advice and support; • ensuring that risk assessments are regularly reviewed. In the event of an incident, accident or process change, the risk assessment must be reviewed immediately; • understanding the University’s health and safety policy statement, codes and guidance, how they are applied within the school, and within the working space of the research team; • maintaining suitable records of exposure to substances hazardous to health, in accordance with University policies and guidance; • arranging for any necessary and appropriate health and safety training, including training identified in the risk assessment; • liaising with specialist advisers, and providing information on request about the risks and control measures; and • ensuring that all research group members respond to, and cooperate with any requests for them to attend for health surveillance and advice. The health and safety management with respect to teaching is usually delegated to programme leaders and course/module leaders. The following duties are included in addition to the duties set out above • ensuring that class teachers, whether University employees or not, are fully informed of all risks and controls required as an outcome of any risk assessments; • monitoring that work-based teaching in partner organisations is undertaken safely and without risk to health. To enable the Academic Supervisors to effectively carry out these responsibilities and, hence, ensure compliance with statutory requirements, the University will provide essential training and development which Academic Supervisors are expected to attend. This will be supported by the production of appropriate standards and guidance. 1.2. FUNCTIONS AND RESPONSIBILITIES (PROF BRYAN HICKEY) 1.2.4 5 Staff with Line Management responsibilities All staff with line management responsibilities including first line supervisors and unit/section leaders have an important role in setting performance standards for their specific area of responsibility and monitoring for standards in these on an on-going basis. They will ensure that risk assessments in their area are completed, that staff are aware of them and that staff are aware of and adhere to all relevant safety policies and arrangements. To enable the Line Managers to effectively carry out these responsibilities and, hence, ensure compliance with statutory requirements; the University will provide essential training and development which Line Managers are expected to attend. This will be supported by the production of appropriate standards and guidance. 1.2.5 Head of School The University Safety Policy [4] describes the responsibilities of Heads of Schools: • To have overall responsibility for ensuring effective health and safety management in your faculty, school or service • To ensure compliance with both legal and University health and safety requirements • To ensure adequate time and resources are allocated for all the requirements to be carried out • To provide leadership for health and safety • To ensure all staff are involved by promoting two-way communication • To establish effective local health and safety procedures and communicate them with staff • To monitor and review health and safety performance within your faculty, school or service • To take appropriate action when procedures have not been complied with • To be involved with accident and incident investigations • To ensure staff are competent to undertake tasks safely 1.2.6 Health and Safety Working Group Day to day safety matters are dealt with by the members of the Health and Safety Working Group. The members of the group are listed in table 1.1 on page 6. The members of the Health and Safety Working Group, the Health and Safety Officer and the Health and Safety Coordinator act as contact points and focal points for the issues that arise. The School Health and Safety Officer , the School Health and Safety Coordinator, the School Laser Safety Supervisor, the School Radiation Protection Supervisor and the Fire Wardens have specific tasks within their area or expertise. An appendix to University Health and Safety Policy gives guidelines regarding the ”Roles of Faculty or School Health and Safety Co-ordinators”. Any health and safety issues which cannot be resolved by a supervisor or line manager should be raised with a Health and Safety Working Group member, with the Health and Safety Officer or with the Health and Safety Coordinator in the first instance. 6 CHAPTER 1.

The members of the Health and Safety Working Group have the authority to stop any work in any laboratory, workshop or elsewhere in the School should the activity or the facilities not meet safety standards. 1.3 Safety inspections (Dr Joachim Rose) There are safety inspections annually for each individual research group, teaching lab and workshop. The inspections are carried out by members of the Health and Safety Working Group together with trade union representatives. Collectively, the inspection team should have sufficient expertise to be effective in spotting potential problems. For example, when inspecting a research group using lasers the laser safety supervisor should be present or a member of the team should have laser safety training. No member of the inspection team should in effect review their own activities; there should be independent expertise present from another member of the inspection team. The head of the research group (or the equivalent for non-research spaces) takes part in the inspection. The inspection team produces an inspection report which contains a list of actions items. The report indicates the severity of a possible accident that may result from the identified problem. The report also indicates the likelihood of an accident. The entries of low, medium, or high are used to decide which deadline to set. During the inspection the deadlines for remedial action are agreed with the head of group, to whom the report is sent promptly after the inspection. It is the responsibility of the head of group to assign a group member for each action items or to find other ways of meeting the deadline. The inspection reports are available to all staff on the share computer system file space. The head of group reports to the School Health and Safety Officer or the Health and Safety Coordinator that the remedial work is complete by returning the signed inspection report. If any problems in meeting a deadline arise the head of group contacts the Health and Safety Officer or the Health and Safety Coordinator to discuss which measures to take. After receiving the signed inspection report the School Health and Safety Officer or the Health and Safety Coordinator (or another member of the safety committee) checks 1.4. RISK ASSESSMENT (DR JOACHIM ROSE) 7 that the identified safety problems have been dealt with. Finally the Health and Safety Officer or the Health and Safety Coordinator sign the inspection report to indicate that all action items have been completed and sends a copy of the reports to the Head of School. If there are still outstanding issues the Health and Safety Officer or the Health and Safety Coordinator takes appropriate action. While the issue is being resolved the Health and Safety Officer or the Health and Safety Coordinator or the Health and Safety Working Group may impose restrictions, shutdown some activities entirely or close down whole laboratories or rooms. 1.4 1.4.1 Risk assessment (Dr Joachim Rose) Legal requirement for risk assessment The Health and Safety at Work etc Act 1974 [1] introduced the concept of reasonable practicability which implies the need for employers to protect persons affected by their work and to provide a degree of control commensurate with the level of risk. The Management of Health and Safety at Work Regulations [10] take this one stage further by explicitly requiring employers to carry out a suitable and sufficient risk assessment. Health and safety risk assessment is the systematic identification of the hazards associated with an organisations work activities and premises; and the evaluation of the risks associated with those hazards: it then involves the identification of the measures necessary to control these risks. The advice in this School Safety Handbook outlines the standards to be achieved for various hazards. It also outlines the control measures which ensure that the risks arising from these hazards are adequately controlled. If however there are additional hazards or specific activities in the school which are not adequately addressed in the School Safety Handbook then the onus is on the school to develop and set standards for the hazard or activity. 1.4.2 Risk assessment procedure The principal responsibility for risk assessment rests with the research group leaders, with the module leaders of laboratory based modules, and with the heads of the school workshops. They have the responsibility to ensure that the risk assessments are carried out for new activities, that the assessments cover all significant risks, that the existing risk assessments are kept up-to-date and that the assessments are of a sufficiently good quality. Ideally the risk assessment is carried out by the person, for example the researcher preparing a new activity, who will later carry out the activity. Each laboratory or workshop should be assessed in a one or more risk assessment documents. Where the assessment of the significant risks becomes too complex, for example because there are several different workplaces or different procedures to consider, a number of individual assessment documents should be prepared. The complete risk assessment is signed by the group leader and forwarded to the School Health and Safety Coordinatorto be approved. Where reasonably practicable all risk assessments should be displayed in the laboratory or workshop. Ideally the risk assessment should be displayed together with the School Safety Notice and a copy of the School Safety Handbook. If this is not practicable then all safety information for a laboratory or workshop should be collected in a file which is visible and easily available to everyone in the laboratory or workshop. The University has introduced software, RIVO, for risk assessment and COSHH assessment. Potential user are encouraged to try RIVO. The Faculty Health and Safety Manager can assist in getting started with the new procedure. 8 CHAPTER 1. SAFETY MANAGEMENT 1.4.3 Guidelines for Risk assessment The Health and Safety at Work Act requires that employers make a suitable and sufficient assessment of the risks to the health and safety of their employees and nonemployees affected by their work. While the requirement to do risk assessments stems from the law, the underlying objective of this is to ensure that risks arising from work activities are controlled and that as a consequence of this no one engaged on work activities gets hurt or becomes ill. 1.4.3.1 Definitions Hazard means ”anything that can, or has a potential to cause harm” (e.g. chemicals, electricity, machinery, etc). Risk is the chance that someone will be harmed by the hazard. How to assess the risks in your laboratory/area. 1. Identify the hazards 2. Determine the people at risk 3. Evaluate the risks and decide whether existing precautions are adequate 4. Record the findings 5. Review the assessment and revise if necessary 1.4.3.2 Risk Assessment: Risk Ranking The Health and Safety Executive use the simple equation: RISK RANKING = HAZARD SEVERITY x LIKELIHOOD OF OCCURRENCE Both the hazard severity and the likelihood of occurrence are categorised, or assessed, on the basis of a for example three point scale. For each category outline guidelines are given to define that category. For Hazard Severity, (i.e. potential for loss), the three categories are: 3 - High: Loss of life / permanent disability / Major injury; Extensive loss of plant or building infrastructure; Prohibition notice served by HSE / Prosecution 2 - MEDIUM: Serious Injury or Illness / Temporary disability; Some damage to plant, equipment; Improvement Notice served by HSE. 1 - LOW: Minor/ non-disabling injury or illness; Minor disruption to plant, equipment For Likelihood of Occurrence, i.e. probability that loss or harm will result from hazard, the three example categories are: 3 - HIGH : once or several times per day/ or per activity 2 - MEDIUM : once or several times per month/ or per activity 1 - LOW : once or a few times per year/ or over lifetime of project The product of the two values is used as the basis to determine the Risk Ranking for each item. As a rough guide, a HIGH Hazard Severity, a HIGH Likelihood of Occurrence or a HIGH RISK RANKING is undesirable and effort should be made to eliminate or reduce these as far as is reasonably practicable. 1.4. RISK ASSESSMENT (DR JOACHIM ROSE) 9 Professional judgement is required to categorise items which represent a breach of a specific statutory provision. Indeed such breaches are difficult to categorise in terms of hazard severity and likelihood of occurrence and the assessors have to decide on whether a specific breach represents a significant issue of non-compliance, in particular whether it would lead to internal or external enforcement action, and from this consideration, decide on whether risk is HIGH, MEDIUM or LOW. This is why it is important for the assessor(s) to have an understanding of the significance of any statutory breach which might arise from an activity. If the assessor is uncertain as to the significance of any breach then he/she can discuss this with the School Safety Supervisor, or other ”competent person”, before signing the risk assessment. 1.4.4 Hierarchy of Risk Control Where an aspect of the activity is ranked as HIGH RISK then the assessor/s should consider whether they have done all that is reasonably practicable to reduce risk taking into account the following risk control hierarchy namely: 1. avoidance /elimination (of risks) e.g. contracting out to specialists with appropriate facilities 2. substitution e.g. using a less hazardous substance or better guarded machine or again subcontracting a dangerous activity 3. controlling risks at source reviewing engineering controls 4. safe systems of work reviewing system of work for activity 5. use of personal protective equipment (PPE) as a last resort to consider whether PPE, as a complementary aspect to the above, could help to reduce risk. e.g. fume cupboard for expelling noxious vapours Similarly when an aspect of the activity is ranked as MEDIUM RISK then the research/assessment team should again consider whether risks could be reduced further by going through the above risk control hierarchy. There is no need to do the above for LOW RISK issues but there is still an obligation to reduce risks to the lowest level reasonably practicable. 1.4.5 Documenting the Risk Assessment The Physics and Astronomy Risk Assessment template is available on the shared internal file space within the /safety top level directory. The risk assessment proforma and any other relevant information e.g. Safe Operating Procedures, Method Statements operators manuals etc. must be communicated to all persons involved with the work. Therefore on an additional sheet those engaged on the activity will be required to “sign up” to the fact that they have had the activity and risks associated with that activity explained to them, and that they have read and understood the risk assessment. Copies of the risk assessment and other documentation such as method statements should be displayed next to fixed equipment/processes or stored in the immediate vicinity so that it is available for consultation or for inspection. 1.4.6 Monitoring, risk assessment and safety inspections To ensure that the risk assessment procedures are operating satisfactorily the regular safety inspections of workshops and laboratories examine the risk assessments. 10 CHAPTER 1. SAFETY MANAGEMENT Both positive examples of good practice and any action items arising from problems are identified in the inspection report. Even though there are regular safety inspections, all group leaders are still responsible to ensure a complete and accurate set of risk assessments is maintained. Whenever there is a significant change, for example, if a new potentially hazardous experimental procedure is introduced, then a new or modified risk assessment is needed. 1.5 Authorisation of laboratory work (Dr Joachim Rose) Prior to the start of any laboratory work the students, staff or visitors involved need to first become authorised as users of the laboratory. The head of group, a direct supervisor or the laboratory manager can authorise users. In each case a decision is made on whether the person is competent to safely work in the lab and has received all relevant information and any necessary training. The lab user authorisation form also indicates whether any out of hours work can take place. The from is displayed in the lab together with the relevant risk assessments. Where there is a change in the laboratory activities with a significant hazard a new risk assessment of the activity is needed. For a person to become a user of equipment or the user of a laboratory the relevant safety training must be complete and documented. The new user must either complete risk assessments for new activities or follow the induction for established procedures. In either case there must be evidence that this process has been completed. 1.6 Authorisation of work by technical staff (Dr Joachim Rose) All requests for workshop time must include the relevant health and safety information from the originator of the request. Before carrying out a task this information, which may in effect be a full risk assessment, is discussed between the technician and the head of workshop, who authorises that the work is carried out. The request form is also used to feed back safety information - new issues may have come to light - to the head of workshop after completion of the task. Minor technical work without completion of a job request and a subsequent discussion of the safety issues should - if at all - only take place if there are very clearly no significant hazards. 1.7 Accident Reporting (Dr Joachim Rose) The University of Leeds Safety Services operate the accident reporting system (Sentinel). The Health and Safety Coordinator and other members of staff are trained in the use of the accident reporting system. A list of trained staff can be found on the School of Physics and Astronomy web pages. The advice from the University of Leeds Safety Services is to record all accidents, however trivial (let common sense prevail) and also all Dangerous Occurrences (’near misses’). The guiding rule is: If in doubt report it. Accidents reports - even of very minor incidents - are a valuable source of information, as they can reveal a hazard that has so far escaped the effort to eliminate or control risks. Chapter 2 Specific Hazards and Procedures 2.1 Fire (Mr Stuart Weston) The University of Leeds Safety Services web page provide Fire Safety information on their web site, http://www.leeds.ac.uk/safety/fire. You should know the location of your assembly point outside the building and the designated emergency escape routes from the building. The emergency escape route and the assembly point depend on where you are in the building. Anyone working in the School should also know the location of the nearest fire extinguisher and of the nearest fire alarm point. 2.1.1 Fire Alarm procedure Circumstances must dictate whether attacking a fire with portable fire-fighting equipment should take priority over summoning the fire service and raising the alarm. Clearly it is undesirable to allow a small fire to take hold through waiting for outside help but it can be dangerous to delay calling for assistance in dealing with any outbreak which may not be quickly extinguished by prompt action. Only use fire fighting equipment if the full extent of the fire can be ascertained and you are confident that the fire can be easily extinguished. In all other cases the alarm should be raised by breaking the nearest break glass call point. If your efforts to extinguish the fire are unsuccessful raise the alarm. Security will be alerted automatically but if there is time contact the Security Office on Ext 32222 with details (i.e. building, room number). Every case of fire must be reported to the School Health and Safety Officer or the Health and Safety Coordinator. 2.1.2 The Fire Alarm System and evacuation of the building As well as manual break glass call points located on emergency escape routes there is an automatic fire alarm system utilising smoke detectors. When either is activated electronic sirens will sound throughout the School. On hearing the fire alarm siren • you must leave at once and make for the official assembly points. Do not wait to be asked to leave. • if at all possible make safe any potentially dangerous equipment or experiments first. • do not congregate around the exits and in particular keep the area around the building clear for emergency services to gain access and park. • do not leave the assembly area or re-enter the building until given permission to do so by the Fire Officer or Fire Wardens even if the alarm has ceased to sound. 11 12 CHAPTER 2. SPECIFIC HAZARDS AND PROCEDURES • never use lifts after the fire alarm has sounded. The only circumstance in which people may remain in the building is during a brief equipment test which use a different sound and which has been announced. 2.1.3 Fire protection equipment • Fire Extinguishers: Fire extinguishers are available in all laboratories, each with a security tag. Every worker must know the position of these fire extinguishers, type and method of operation. It is too late to learn this when a fire starts! If you use a fire extinguisher or note the loss of the security tag this must also be reported to the School Safety Supervisor or a Fire Warden to obtain a prompt replacement. Remember a colleague’s life may depend on it. • Fire Blankets: These are provided in red containers fastened to the wall at various points in the building. They are primarily intended for use when clothing catches fire and may be quickly removed from their containers by a downward pull on the tape attached to the blanket. Wrap the victim in the blanket and make them roll on the floor. The use (or unpacking) of a fire blanket must be reported to the School Safety Supervisor. • Fire Doors: Fire resistant doors are strategically placed in corridors and at the entrance to laboratories to limit the spread of fire and smoke throughout the building. Never leave such doors wedged open. Please be vigilant to make sure they are closed at all times. The School has appointed Fire Wardens whose main duties are to assist in the evacuation of the building in the event of fire. On these occasions they normally wear an identifying arm band or a high visibility vest. The Fire Wardens regularly check the fire protection equipment. Fire precautions and other related activities are coordinated by Mr Stuart Weston. 2.1.4 Fire Wardens A list of fire wardens can be found on the School Health and Safety web pages. The duties of School Fire Wardens include: 1. monthly check of the alternative exit routes. 2. ensure that all staff and post graduate students are familiar with the alternative routes. 3. check that corridors and staircase enclosures are not used for the storage of combustible materials. 4. check that fire resistant and self-closing doors are not wedged open or fastened back. 5. carry out a monthly check of fire fighting equipment. As part of fire drills fire wardens ensure that staff and post graduate students are aware of the procedures to adopt when: 1. a fire is discovered 2. on hearing the fire alarm 2.2. ELECTRICAL SAFETY (MR RICHARD OLIVER) 13 3. ensure that the area is evacuated. 4. assist Security to prevent any persons re-entering. 5. liaise with the Safety Officers and or Security regarding any local knowledge which may be of assistance to the Fire Authority. Re-Entry Procedure: 1. at small incidents liaise with Security regarding the re-entry. 2. at prolonged incidents or where contamination is suspected liaise with the Safety Officer, the assistant Safety Officer or in their absence the representative from the Division of Works and Services. 3. if requested to do so assist the Safety Officer or the representative from the Division of Works and Services to carry out any safety tasks prior to the general re-entry. Evacuation Drills: 1. where practicable arrange for evacuation drills to be carried out annually. 2. where a full evacuation drill is impracticable an evacuation exercise should be arranged annually. General Fire Precautions: 1. give advice and approval on the use of naked flame and the heating of combustible materials. 2. ensure that LPG and open element electrical fires are not used. 3. inform the Safety Service on any change which may effect the means of escape or other fire precautions. 2.2 Electrical Safety (Mr Richard Oliver) Follow this code of behaviour: 1. All incoming new electrical equipment should be channelled through the School Stores, so that it is recorded on the School Register for a PX Number to be allocated, after which it must be tested for electrical safety (using a Portable Appliance Tester (PAT)). The details of the tests are then downloaded onto a database. In this way the frequency of the tests for particular electrical equipment can be controlled. There should be regular visual inspection of items particularly prone to wear or abuse e.g. flex and cable, at reasonable intervals. 2. Do not interfere with any electrical apparatus or equipment or attempt to repair it unless you are an electrician and authorised to do the work. 3. All plugs must be in good condition. Any damaged plugs or plugs which get hot when in use must be changed. Whenever possible, 3-core cable should be used to permit proper earthing of apparatus. 4. Do not change fuse ratings arbitrarily, Electricians are the right people to determine and set the fuse ratings. All 13 amp three pin plugs must be fitted with a fuse rated for the equipment concerned. 14 CHAPTER 2. SPECIFIC HAZARDS AND PROCEDURES 5. Keep distribution boards and similar installations clear of obstruction and water spillage at all times. Do not overload distribution boards or adapters. Heaters and Electric Kettles should always be connected directly to the wall outlet and not to a distribution board. If in doubt, contact the Electronics Workshop for advice. 6. Where extension multi-sockets are used, care must be taken to ensure the total loading does not exceed 13 amps. Extension multi-sockets should not be daisychained together. 7. Do not improvise with electrical equipment, this means: (a) Never jam wires into sockets with matchsticks or nails. (b) Never run power tools from lighting sockets. (c) Never hang flexible cables over nails, leave them where they can get damaged or wet, or frozen if liquid Nitrogen is likely to be spilled. Do not use them to lift or pull the equipment to which they are connected. (d) Where possible, cables should be strapped into a neat bundle and secured. (e) Cables crossing open floor areas should be covered with cable protectors. (f) The interchanging of cabling between appliances should be avoided. This will ensure correct fuse ratings for the appliance. 8. Large items of metal equipment (e.g. laser tables, lathes, vacuum line frames etc.) should be separately earthed. Accidents have resulted when such apparatus has become live. 9. Report details of any ineffective or damaged electrical equipment to the Electronics Workshop Supervisor. Do not use it until it has been repaired. 10. It is illegal under workplace law to intentionally or recklessly interfere with or misuse any electrical equipment. Never override any safety interlocks. 11. The Electronics Workshop run courses in the use of the PAT tester so that groups can then carry out their own electrical safety checks using the PAT tester. This normally records the Earth bonding, Insulation resistance and load current. Mains leads should be PVC coated, colour coded Brown (live), Blue (neutral) and GreenYellow (earth) and be of the correct current rating for the equipment concerned. Serious accidents to personnel and damage to apparatus can result from failure to observe this wiring rule. Some equipment of foreign manufacture may not comply with this colour code. In cases where foreign colour codes are used a member of Electronics Workshop staff should be consulted. Visitors from overseas please note that the British system of colour coding is different from that used in certain other countries. The use of private electrical equipment must be reported to a member of Electronics Workshop staff who will arrange for it to be tested. If any electrical equipment is disposed of the Electronics Workshop need to be informed of its appliance number. Further details on PAT testing are available in appendix C 2.3 2.3.1 High Pressures (Mr Stuart Weston) Pressure Vessels Pressure vessels (operating above 1.5 bar or 22.5 psi), or when the product of pressure (in bars) and the volume in litres exceeds 250 bar litres, officially require annual 2.4. MANUAL HANDLING (MR STUART WESTON) 15 inspection and certification and should only be used if they have a valid current certificate. Before ordering pressure vessels or starting to operate any pressure vessel the School Health and Safety Coordinator (Mr Stuart Weston) should be contacted. 2.3.1.1 Gas Cylinders Cylinders must not be moved with the regulators attached. Cylinder trolleys must not be used to store cylinders. A cylinder must never be left free-standing but be securely clamped or held in a proper stand. Cylinders must be fitted with regulators appropriate to the type of gas and cylinder pressure. Oxygen cylinders, in particular, should only be used with oxygen gas regulators. Regulators must not be greased and normal PTFE tape must not be used to help seal cylinder regulator connections. Grease and normal PTFE tape (which is highly plasticised) can spontaneously combust/explode in contact with compressed oxygen. A more expensive grade of safe PTFE tape (from Manchester Valve and Fitting) can be used. Whilst this is mainly intended for use in connection with oxygen lines, since confusion can easily occur, it is recommended as the only grade for all uses. Return faulty regulators and report leaking cylinders to Stores. Diaphragm valves have a useful life of about five years and should have either a date of issue or retest date label and should not be used after this date. It is good practice to fit cylinders of flammable gas with an appropriate flash arrestor and for some applications this is required as for example when the mixture formed downstream is inflammable or potentially explosive (e.g. hydrogen/ air-oxygen or hydrocarbon/air oxygen). For further details consult the HSE website http://www.hse.gov.cdg/pdf/safusgc.pdf 2.4 Manual Handling (Mr Stuart Weston) The Manual Handling Regulations 1992, in principle, require generic risk assessments to be made for all lifting, carrying, moving tasks, etc. In practice this only becomes a regular problem for a few members of staff but there are obviously some jobs and some circumstances (e.g. for new or expectant mothers) where the risks are real and need to be considered very carefully. Never try to move very heavy equipment on your own. Remember that manpower can be provided at both University and School level and that lifting equipment suitable for some difficult jobs is kept by the Mechanical Workshop. The HSE publication Guidance on Manual Handling Regulations is useful or and manual handing web pages ar http://www.leeds.ac.uk/safety. 2.5 Office Safety (Dr Joachim Rose) The University has produced detailed training material and protocols for office safety which those working principally in an office environment need to read. In particular everyone regularly working with Display Station Equipment must carry out an online risk assessment of their workplace. This includes a training element in the safe use of DSE. See the web pages at http://www.leeds.ac.uk/safety. A common cause of overheating of office equipment and sometimes of fires is the obstruction of the ventilation, particularly with thoughtlessly placed sheets of paper. Unless closed on sides electric radiators including fan units should not be used. Office equipment must carry a valid Portable Appliance Test (PAT) label or not be used. 16 2.6 CHAPTER 2. SPECIFIC HAZARDS AND PROCEDURES Flood, gas leaks and electrical breakdown (Mr Stuart Weston) During the working day cases of floods, gas leaks or electrical breakdown should be reported directly to Works and Services (tel. 35555 ) and the School Safety Supervisor should also informed. After normal working hours University personnel are at home but on stand-by. They can be contacted through the Security office. Contact University Security Ext. 32222 and report the incident. You must give your extension number. The Security Officer will telephone the appropriate person on stand-by. In some cases it will be possible for you to talk directly to the person concerned. Otherwise the Security Officer will relay your report. 2.7 Out of Hours Working and Working Alone (Dr Joachim Rose) Working out of normal hours, before 8:00 or after 18:00, or working alone can increase the severity of an incident or accident. For example, the person involved can become incapacitated and therefore not able to summon help. Even if an alarm is raised there may be no trained or knowledgeable staff present to help (first aiders, co-workers, technical staff). Experimental work out of normal hours or alone therefore requires a risk assessment that addresses the additional hazards and the increased severity of incidents that may arise. The risk assessment must be approved prior to authorising any out of hours laboratory work. Additional risk assessment guidelines apply: • Laboratory work alone or out of normal working hours should only be considered if it is unavoidable. • Any risk of the person(s) involved becoming incapacitated and thus unable to get assistance is not acceptable. Any such activity is forbidden while working alone or out of normal hours. • The risk assessment must detail the measures to either eliminate or else to substantially reduce the impact of incidents while working alone or out of normal hours. • An emergency plan, attached to the assessment and posted at the workplace, must detail how to respond to the situation and especially how to raise the alarm and how to obtain any necessary assistance (security, fire brigade, first aider, technical help). • In case of an unrelated incident, for example a building fire, Security (first contact for fire brigade and ambulance services) need to know who is present in the building and where. The risk assessment must therefore outline a procedure to guarantee that the information is available to Security and that it is correct. In future a swipe card system at every laboratory door may provide information to Security. Until then other arrangements must be operated to inform Security. Records should be kept to monitor that the arrangements are working. Out of normal hours office work alone or computing work alone in a low hazard environment is discouraged. Where available a swipe card system or an internet login system must be used to ensure the presence and location of the person in the building is known. There are procedures for the use of the School telescopes at night. Before the first night of unsupervised observing with the one of the School telescopes, first contact 2.8. UNATTENDED OVERNIGHT EXPERIMENTS (DR JOACHIM ROSE) 17 Prof M G Hoare to discuss how to get access to the telescopes and which precautions and safety rules to follow while observing. The list of rules is posted on the telescope web site, in the telescope warm room, and paper copies of the list are given out. 2.8 Unattended Overnight Experiments (Dr Joachim Rose) Minimise overnight running of experiments to the absolutely necessary minimum. If any experiment or equipment is left on overnight it is your responsibility to make sure that it is safe and fail-safe. The required risk assessment for an overnight experiment or processes needs to address the increased hazard and the describe the specific measures to eliminate or reduce the hazard. 2.9 2.9.1 Teaching labs and project work (Dr Peter Hine) Laboratory safety tours All students working in one of the teaching laboratories for the first time or starting project work are required to take part in a safety tour of the laboratory. This safety tour informs the students about the location of safety equipment, such as fire extinguishers or first aid boxes, and of the safety procedures, for example in the event of a fire. The attendance of students is recorded to make sure all students do take part. 2.9.2 Laboratory experiments The handbooks for undergraduate laboratory modules include information on general laboratory safety and on the general safety procedures. In addition both the University Health and Safety Handbook and the School Health and Safety Handbook are available in teaching laboratories. For undergraduate laboratory experiments which are not covered by the general safety information and the safety procedures in the handbook extra more detailed safety information is provided. This is done either by including the safety information in the description of the experiment in the laboratory handbook or by displaying a safety note at the workplace. Additional detailed information, for example risk assessments, COSHH assessments or rules for working with radioactive sources, should be referred to and should be attached in appendices. Like any other possibly hazardous activity undergraduate laboratory work requires a prior risk assessment. Some experimental activities may require their own detailed risk assessment, while other experiments may be included in a generic risk assessment covering the activities in the lab. The risk assessment are displayed in the laboratory and should be discussed by the demonstrators with the students before allowing students to start on a new experiment. Demonstrators and staff will ask a student to leave the laboratory, if they have reason to think that the student is insufficiently prepared to work safely or that the student is not following the health and safety procedures and rules. 2.9.3 Project work Dissertation type projects, which may include some computer work, do not require the completion of a project safety note. For experimental projects a safety note is required and is drafted by the project supervisor. The note is then discussed and signed by both the project supervisor and the project students before the start of the project work. A copy of the safety note is kept by the students and is displayed at their workplace. A further copy is held by Dr Hugo Christenson(level 3) or Dr Stuart Lumsden(level 4). Any safety issues should first be discussed with the project supervisor. If uncertainties 18 CHAPTER 2. SPECIFIC HAZARDS AND PROCEDURES remain then students and staff are encouraged to contact the module leader, the School Safety Supervisor or any member of the School Safety Committee. 2.9.4 Teaching laboratory safety management The safety of laboratory experiments and of project work is the responsibility of the module leaders in close contact with the School Safety Supervisor. The members of the school safety committee assist in the assessment of potential risks such as lasers, radiation sources, or the use of chemicals. The school safety committee carries out regular inspections of the health and safety arrangements in teaching laboratories. 2.10 Non-ionising radiation (Dr Ben Johnson) 2.10.1 Laser safety procedures 2.10.2 What is required Every new laser user in the school is required to register with the School Laser Safety Supervisor and with the University Radiation Protection Service. Registrations forms are available from the School Laser Safety Supervisor. New laser users are also required to attend the University laser safety course, where notes on protection against non-ionising radiation’ [3] will be issued and a certificate of attendance will be provided. This certificate is a requirement for all researchers working in the University with lasers, class 3b or above. It is both the user’s and the research supervisor’s responsibility to ensure that the registration and any relevant training is completed before work commences. Every laser user in the school is required to adhere to the operational and safety procedures outlined the Universities "Local Rules for the Safe Use of Lasers" - a copy of which can be obtained from the Laser Safety Officer. [7]. N.B. The whole area of Laser Safety is currently being reviewed at the University Level, with new guidance and procedures due to be implemented towards the end of 2011. 2.10.3 School Laser Safety Supervisor The School Laser Safety Supervisor conducts an annual laser safety inspection in the context of the risk assessment made by the laser user. The School Laser Safety Supervisor provides advice on laser safety procedures and sources of supply for laser safety equipment. 2.10.4 Procedure in case of an accident Depending on the seriousness of the accident the priority is to obtain medical attention for the injured party. A list of School First Aiders is displayed in all laboratory areas. The accident should be reported (see the section on accident reporting on page 10) and the School Laser Safety Supervisor informed. The School Laser Safety Supervisor will assess the cause of the accident and will require that precautions are taken to prevent a repetition. The user will be required to assist in this follow up procedure. 2.10.5 Microwaves and UV Radiation All persons intending to work with microwaves at high power (e.g. microwave ovens) or ultra-violet radiation must discuss their work with the Radiation Protection Supervisor of the School. Long term exposure to bright light, particularly in the ultra violet, can lead to premature ageing of the eye and cataract formation in later life. 2.11. IONISING RADIATION (DR PETER HINE) 2.11 2.11.1 19 Ionising Radiation (Dr Peter Hine) Local Rules (University of Leeds, Part 2) It is the responsibility of all members of the School who wish to carry out experiments involving the use of ionizing radiations to be aware of: 1. the statutory regulations governing the use of ionizing radiations 2. the University regulations relating to the use of ionizing radiations 3. the School Rules governing the detailed application of the regulations in 1 and 2. A copy of the Local Rules, Part 1, is issued to prospective ionising radiation workers by the University Radiation Protection and Safety. The School Rules are set out below and all radiation workers are given a copy of this document before they start work. 2.11.2 Registration A risk analysis carried out by University Radiation Protection Service has concluded that the four research grade x-ray diffractometers situated in room 8.237 and the student x-ray experiments situated in the undergraduate labs are inherently safe in design. It has therefore been deemed by the University Radiation Protection Service and Safety Service that only members of the school who are directly involved in maintenance /or live alignment of the x-ray optics should be registered with University Radiation Protection Service (http://rsid.leeds.ac.uk/). Note that all users must still register with the School Radiation Protection Supervisor (SRPS). All prospective new users must first contact the SRPS (Dr Peter Hine for undergraduates or Dr Mannan Ali) who will arrange training and ensure that all safety aspects have been highlighted. Short term visitors to the School who wish to use any radiation facilities should contact the SRPS before starting work in order to obtain temporary clearance and local registration. 2.11.3 Purchase of Radioactive Sources or Radiation Generators Any new proposal to use or purchase a radioactive source or an X-ray generator must, in the first instance, be discussed with the SRPS. Orders for radioactive materials or sources must be countersigned by the SRPS(Dr Peter Hine) or, in his absence, by the School Safety Supervisor. All radioactive materials or sources must be purchased via University Radiation Protection Service in conjuction with Dr Peter Hine. 2.11.4 Location of Radioactive Sources Radioactive sources are under the control of Dr Peter Hine. Sources may not be removed from the designated rooms, transferred from one location in the School to another or removed from the School without notifying either Dr Peter Hine(SRPS) or University Radiation Protection Service. 2.11.5 Return of Radioactive Sources after Use Radioactive sources no longer needed for a particular piece of work must be returned to Dr Peter Hineeither for storage or, if applicable, disposal via the University Radiation Protection Service. 2.11.6 Dosimeters Dosimeters are no longer used in the school for day to day users. 20 2.11.7 CHAPTER 2. SPECIFIC HAZARDS AND PROCEDURES Controlled Areas Certain areas in the School are designated as “Controlled Areas” (Appendix B.2) . These areas may only be entered by persons who are working to an appropriate scheme of work. For the purposes of the rules a “Controlled Area” may be a small volume forming part of a piece of experimental equipment. Such areas will be clearly labelled and identifiable. “Entering a Controlled Area” does not necessarily mean entering it with the whole body. 2.11.8 Cleaning of Rooms The only relevant rooms are room 8.237 where the Polymer X-ray generators are housed and the teaching laboratories. The cleaners come in daily to sweep the floor. No special precautions or warnings are issued since the X-ray tube heads and associated equipment in room 8.237 are housed in 100% radiation proof enclosures and there is no radiation background in the rooms over the normal environmental background which is common to all rooms. The equipment in the teaching laboratories is switched off outside normal laboratory hours. 2.11.9 2.11.9.1 Summary of Sources of Ionising Radiation in the School Radio nuclides All sources are sealed and of comparatively low activity. Holdings have been allocated to the School under the Radioactive Substances Act 1993. A current list of actual sources held and their location is maintained by the School Radiation Protection Supervisor (Dr Peter Hine) and is mirrored on the University Radioactive Source Database. At the beginning of each academic year the Radiation Protection Services audits the sources and wipes for leaks. A copy of the report is sent to the SRPS. The closed SPUCRS registration certificate is displayed with the sources and on a notice board. Each month these sources are checked in their storage cupboard located in room 8.10j. Whenever these sources are used in the second year teaching laboratory they are kept in a temporary, lead protected storage area. New additions to the stock of sources and any movement from the School are reported to the Radiation Protection Services when they occur. A current copy of the Registration Certificate is displayed on a School Safety Notice Board in the Small Common Room. 2.11.9.2 Machine Sources All machine sources are X-ray Generators used for X-ray crystallography. There are four research grade x-ray diffractometers situated in Room 8.237 (x-ray Lab). Four Rontgengerat Leybold didactic generator 55481 capable of 1 microsievert per hour situated room 8.10 (UG Lab) along with five miniature generator/goniometers -Tel-X-Ometer situated room 8.30(UG Lab). 2.11.10 Regular Testing of X-ray Generators The superstructures of the three DG2 generators in room 8-237 are all surrounded by interlocked enclosures. These are checked for radiation leakage by the SRPS or by an appointed person every six months using an appropriate monitor (Provdied by University Radiation Protection Service) and the results are recorded in a book which is kept in the laboratory and the SRPS (Dr Peter Hine) is informed of the results. Any problems are dealt with and the leakage rectified before the generators are used. The Tel-X-Ometer and Leybold didactic generators in room 8.30/8.10 are tested (Dr Peter Hine) for leakage at the start of each term when they are to be used and a written 2.12. FIRST AID (MR STUART WESTON) 21 record is kept of the results. 2.12 First Aid (Mr Stuart Weston) Before beginning any work the location of the nearest qualified First Aider and of the nearest first aid box should be established. A list of qualified first aid personnel, their locations and phone numbers, and a list giving the location of all first aid equipment in the school should be displayed in all laboratory areas. Any use of a First Aid box should be reported to a first-aider who will arrange replenishment of any items used. Before ordering new First Aid supplies please contact the School Health and Safety Coordinatorfor advice. Even when no First Aider is called then accidents and incidents should still be reported. See the section of accident reporting 1.7. Arrangements for First Aid in the school are co-ordinated by Mr S Weston (phone 33819), who can give advice on becoming a First Aider, training, and on first aid equipment. The Student Medical Practice are prepared to provide on-campus assistance in emergencies but recommend that injured personnel or students are taken directly to Leeds General Infirmary (LGI) Casualty school. The Student Medical Practice can be contacted on telephones with an outside line on 9 295 4488 or on internal telephones via the Security Office 32222 . The School aims to train all first year postgraduates in first aid. This training is part of the generic skills training. The qualification as a First Aider remains valid for three years. 2.13 Undergraduate project safety (Dr Peter Hine) At the start of any undergraduate project work a project safety note should be drafted by the supervisor and is then discussed with the project students. The project safety note includes: 1. Module code and module title: 2. Project title: 3. Project supervisor(s): 4. Project student(s): 5. Before start of project: 6. Each student should consult the School Safety Handbook and know where to find copies of the handbook. A laboratory safety tour of all relevant laboratory areas takes place. The safety risks and the safety procedures for the project are: 1. Manual handling: 2. Electrical hazards: 3. Chemical substances: 4. Lasers or ionizing radiation: 5. Other risks and procedures: 22 CHAPTER 2. SPECIFIC HAZARDS AND PROCEDURES 6. Arrangements for working unsupervised, alone, or out-of-hours: 7. The safety risks and relevant safety procedures for the project have been discussed between supervisor(s) and project student(s). All safety questions arising have been answered. The information in this safety form is complete and correct. Any safety actions required before the start of the project work have been taken. 8. Signature(s) of project supervisor(s), date: 9. Signature(s) of project student(s), date: Project students are encouraged to immediately contact Dr Hugo Christenson(level 3 projects) or Dr Stuart Lumsden(level 4 projects) or the School Health and Safety Officer about any safety concerns that still remain after discussion with the project supervisor. 2.14 Chemical Safety (Dr Ben Johnson) 2.14.1 Chemistry Procedures 2.14.1.1 General Much experimental research involves the use of hazardous chemicals particularly for the preparation of samples, from simple cleaning with common solvents to complex organic synthesis. The COSHH regulations (Control of Substances Hazardous to Health) require that all activities involving the use of hazardous chemicals must be assessed by the person concerned before the procedure is carried out and checked by a responsible person (see below). Most laboratories have their own local procedures. For the Main BioPhysChem Lab (8.331) and the Satellite BioPhysChem Lab (8.312), the essential rules that everyone (including those not intending to use the lab) needs to know are: Access is strictly controlled (through an electronic system) and will only be granted once a full lab induction has been given by Ben Johnson. 1. Special local rules apply (read notices on the door) especially including (a) There is CCTV in use for the purpose of safety management and security. (b) Lab Coats and safety specs must be worn at all times. (c) Laboratory hours are 8.30 am to 5.30 pm unless an out of hours risk assesment has been completed and fully authorised and the control measures implemented. 2. Any chemical process must have a completed COSHH form associated with it in the red folder in the lab. Even if the process has been deemed non-hazardous, the COSHH form shows that the chemicals and the process has been assessed and been designated as non-hazardous 3. All stock chemicals must be on the inventory database. Any items found not on the database will be disposed of, without notice. All chemicals must be left in a clean and safe state and be clearly and correctly labelled: What, Who, When, Hazard. The labs are communal facilities and good housekeeping is to be observed at all times. 2.14. CHEMICAL SAFETY (DR BEN JOHNSON) 2.14.2 23 COSHH The essential purpose of the COSHH regulations (Control of Substances Hazardous to Health) is 1. to know the hazard of the chemicals involved (both initial and reaction products) and 2. to minimize the risk of people being exposed to that hazard. The COSHH regulations require that all experiments etc. involving the use of chemicals must be assessed by the person concerned according to hazard and risk before the procedure is carried out. Normally this involves filling in a COSHH form which can be downloaded from the School of Physics website (under Safety) and filled in electronically. It is then scrutinized, checked and the experimenter cross-examined about their procedure by a responsible person familiar with COSHH and who then signs the form. (At the time of writing, COSHH authorisers are Ben Johnson and Hugo Christenson). The signed COSHH form must be clearly displayed adjacent to the experiment being undertaken (red file near door for the Chemistry Lab). It should be clear, concise and readable by anyone. In the event of an accident etc., the COSHH form provides information for any rescuer of the hazard and risk of the experiment. The COSHH form contains a number of sections: 1. Personnel involved: 2. Workplace: laboratory no etc. 3. Brief description of experiment: it is useful to include here the amounts of the substances involved. 4. Substances involved: clear and precise name. 5. Hazards identified: simple readable descriptions, e.g. corrosive, flammable, irritant etc. 6. Sources of information: all chemical suppliers are required to provide safety sheets on the chemicals they supply. This is usually too much information, provided to cover the supplier’s back and is not always very helpful. Other information is available in suppliers catalogues and in the library. 7. Precautions to be taken: (a) under normal conditions (storage, handling, etc) e.g. wear specs, gloves, handle in fume cupboard etc. (b) in an emergency: e.g. how to deal with spillage. 8. Procedure for disposal of waste material: when the experiment is complete how is the waste to be disposed of. If it cannot be thrown away or flushed down the sink, it can be disposed of formally via the waste management procedure. 2.14.3 Advice on how to assess risk The COSHH forms and advice on the assessment of risk may be obtained from Ben Johnson who also has the relevant literature. If the substances involved are particularly hazardous then the assessor should seek sustained and professional advice, possibly from several sources. It maybe necessary to undertake the experiment in specially controlled premises outside the School of Physics. 24 CHAPTER 2. SPECIFIC HAZARDS AND PROCEDURES 2.14.4 Waste Disposal Anything which could be seen by the general public as offensive (e.g. gloves, plastic tubes, petri dishes etc) must be disposed of in an Offensive Waste Bin. These are available from Ben Johnson, who will also arrange their emptying and disposal when full. Only certain chemicals can be thrown in the bin or poured down the drain. The rest need to be disposed through Ben Johnson in a controlled and specified manner. Ben needs to be informed of what the material is, its likely hazard, the quantity, whose it is (or contact name), the origin (radioactive or hazardous materials must be negotiated in advance) and where it is presently located. Materials left for waste disposal must not be left in a hazardous state, and must be clearly labelled what, hazard, who. Ben will then arrange for the items to be safely stored in a designated area until collection by an outside company. 2.15 Working at Height (Mr Stuart Weston) The Work at Height Regulations 2005 apply to all work at height where there is a risk of a fall liable to cause personal injury. They place duties on employers, the selfemployed, and any person that controls the work of others (for example a workshop manager, a principal investigator or a module leader who may direct others to work at height). The Work at Height (Amendment) Regulations 2007 which came into force on 6 April 2007 apply to those who work at height providing instruction or leadership to one or more people engaged in caving or climbing by way of sport, recreation, team building or similar activities in Great Britain. As part of the Regulations, duty holders must ensure: • all work at height is properly planned and organised; • those involved in work at height are competent; • the risks from work at height are assessed and appropriate work equipment is selected and used; • the risks from fragile surfaces are properly controlled; and • equipment for work at height is properly inspected and maintained. There is a simple hierarchy for managing and selecting equipment for work at height. Duty holders must: • avoid work at height where they can; • use work equipment or other measures to prevent falls where they cannot avoid working at height; and • where they cannot eliminate the risk of a fall, use work equipment or other measures to minimise the distance and consequences of a fall should one occur. The Regulations include schedules giving requirements for existing places of work and means of access for work at height, collective fall prevention (eg guardrails and working platforms), collective fall arrest (e.g. nets, airbags etc), personal fall protection (e.g. work restraints, fall arrest and rope access) and ladders. See the Health and Safety Executive web site [5] for more information. The site gives Work at Height Solutions to provide good practice advice for people planning a task that involves work at height. There is a list of solutions and a Frequently Asked Questions section. 1 1 The text of this section is adapted from the HSE web site pages. 2.16. OFF-CAMPUS WORK (DR JOACHIM ROSE) 2.16 25 Off-campus work (Dr Joachim Rose) Postgraduate students or staff within the School of Physics and Astronomy may have to work off-campus for some time period. For example to attend a conference or to use an external research facility. The health and safety rules and regulations still apply as they would on campus. • The off-campus work and the travel to and from the off-campus site may not significantly increase the risk. For example a conference trip within Europe, travelling by train or with a major airline. In such cases postgraduates or staff should indicate this on the Application for Approval for Leave of Absence Form 2 . • If either the proposed off-campus work itself or the necessary travel do lead to a significant increase in risk then a prior risk assessment is required. In this case the Application for Approval for Leave of Absence Form should reference an approved risk assessment for the trip. For repeat visits, provided there have been no significant changes, it can be reasonable to refer to an earlier existing risk assessment. • There may be occasional cases where it is not reasonably practicable to carry out an advance detailed analysis of each hazard. In such cases the risk assessment should then describe the potential hazards as far as they are known, together with the steps that will be taken to reduce the risks. For example, the person travelling may be sufficiently competent to respond appropriately to an unforeseen situation or he or she will receive suitable training by the external organisation prior to starting the off-campus work. Undergraduates need to discuss the safety arrangements for off-campus work with the project supervisor or module leader. The safety arrangements are then recorded in a form which is handed into the undergraduate office prior to the trip. 2.17 Software controlled systems (Dr Joachim Rose) The data acquisition systems and instrument control systems in research labs and workshops often contain processors and associated software. In the worst case even a simple malfunction, such as a false reading, may not only result in damage to equipment but also in major injury. Changes to either the operating system or the application software can have unintended or unforeseen consequences. For example a well intended overnight remote modification of the operating system aimed at saving energy by letting idle computers go to sleep can disable a vital control system thus leading to a major incident. Hardware and software in research labs and workshop should therefore be under the direct and full control of local staff who understand the potential impact of configuration changes, who can carry out tests for correct behaviour and who are able to handle and contain the impact of failure situations. • Modifications to laboratory equipment, including any related related software, must only be carried out by the laboratory staff or the workshop staff unless by prior agreement or in response to a request by the laboratory manager or the head of the workshop to involve staff (or contractors) which are external to the laboratory or workshop. 2 http://www.physics.leeds.ac.uk/forms/index/absence-form 26 CHAPTER 2. SPECIFIC HAZARDS AND PROCEDURES • Within research labs and workshops any mechanism for remote or automatic operating system modification or application software upgrades should be disabled, unless the laboratory manager or head of workshop decides that it is desirable and safe to enable automatic or remote modification. • Physical access to the equipment in a laboratory or workshop (as a supervised visitor) requires the prior permission of the laboratory manager or the head of the workshop. A procedure for the activity must be agreed and the safety implications need to be discussed. A record of the authorisation by the laboratory of workshop should be kept. • If there is a possible hazard then a prior risk assessment of the activity is needed, which then requires approval before the modifications are carried out. • Any agreed work by IT support staff (or any other persons external to the laboratory or workshop) needs to be monitored and supervised by laboratory staff or workshop staff. Laboratory and workshop staff must be actively involved at a level that allows them to maintain a detailed understanding of the state of the system and of the potential impact of any changes. • As far as practical safety critical systems should be isolated from any network or protected against incoming connections, unless the lab manager or head of workshop decides that it is desirable and safe to enable network access. • If there is no other practical alternative then accounts for persons external to the laboratory or workshop, for example IT support staff, can be created. These accounts must never used to circumvent or disable the access restrictions for laboratory or workshop equipment. Similar arrangements apply to systems and software outside the laboratory or workshop, for example in office environments, if they are used to develop safety critical software, are used as an external monitor or as a remote control station or if they are in some other way safety critical. Appendices 27 Appendix A Chemistry Laboratories The two chemistry laboratories (8.331 and 8.312) have over 50 combined registered users - from simple sample cleaning to complex organic synthesis. It is essential that all users are aware of what they and other users are doing. All users must undergo an induction into the lab, before use is authorised. The Laboratories are run by Dr Ben Johnson, who is responsible for the day-to-day running of the laboratories and is empowered to ensure that users follow the correct procedures. Training about the correct procedures is given during the lab induction. Regular laboratory users may be required to undertake additional general laboratory duties. A.1 Undergraduate Physicists doing Chemistry (Dr Ben Johnson) Undergraduates are not permitted to work alone in the chemistry labs. Any process being undertaken by undergraduates in the lab must have a COSHH assessment and be limited to low hazard processes. Further guidance must be sought from the lab manager prior to work commencing. A.2 Implementation of COSHH in the Chemistry Lab (Dr Ben Johnson) In both Chemistry Labs, COSHH forms are not kept adjacent to the experiment in progress where pieces of paper could constitute a fire risk! Instead the COSHH forms referring to experiments currently in progress are to be kept in the marked red file clearly displayed near the laboratory door. A.3 Lab Usage Guidelines (Dr Ben Johnson) Usage guidelines, recommendations etc. for the lab are constantly evolving, so please check the lab’s website to keep up to date with these: http://www.mnp.leeds.ac.uk/ biophyschemlab. 29 30 APPENDIX A. CHEMISTRY LABORATORIES Appendix B Radiation safety B.1 Radiation Protection Supervisor (Dr Peter Hine) The School Radiation Protection Supervisors are: Dr Peter Hine, Ext:36648(Radiation Sources and X-rays). In his absence Dr Mannan Ali, Ext:33833should be consulted. B.2 Controlled areas (Dr Mannan Ali) The following areas in the School are designated as controlled areas, access to which is restricted to workers operating under a written system of work. Most of the controlled areas are regions of space in the vicinity of X-ray Generators and are not to be considered as controlled areas when the generators are switched off or if the high voltage supply to the appropriate X-ray tube is clearly off. Room 8.237 - X-ray Laboratory The interiors of each of the three enclosures mounted on the X-ray generators. These enclosures contain the X-ray tube, tube shield and associated equipment and the doors are interlocked with the generator and shutter controller. Rooms 8.10, 8.30 - First and Second Year Laboratory The interiors of the clear Perspex housing which serve as safety shields for the Telx-ometer X-ray generators in the First Year Laboratory. When the mains supply to these units is interrupted the interior of the enclosure is no longer a Controlled Area. B.3 Rules for undergraduate work with ionising radiation (Dr Peter Hine) For the attention of undergraduate students carrying out experiments with ionising radiation All workers with ionising radiations have the obligation:1. to be aware of the hazards associated with such radiation 2. to follow rigorously any procedures and practices specified in the manuscript for the conduct of a particular experiment Accompanying the experiment which you have been given to perform you will find listed certain procedures which have been devised for the safe handling of radio nuclides or for the safe operation of machine sources of radiation. You MUST NOT deviate from these procedures. If any problem arises in connection with the procedures you MUST consult a demonstrator or the laboratory technician before proceeding. B.4 Rules for X-ray generators in room 8-237 (Dr Mannan Ali) For the attention of users of the X-ray generators in room 8.237. 31 32 APPENDIX B. RADIATION SAFETY New users and anybody who is unfamiliar with a particular piece of equipment or technique involving use of one of the X-ray generators must consult one of the two persons named below in order to obtain appropriate instruction. “Second hand” instruction is potentially hazardous and must not be sought. The enclosures on the X-ray generators are interlocked to prevent access to the beam. No attempt should be made to defeat these interlocks at any time. If any problems arise which require access to the X-ray beam or if the equipment malfunctions or if instruction is required Dr Mannan Ali, Ext:33833, should be approached: B.4.1 Work inside interlocked enclosures General Protocol for working inside the interlocked enclosures mounted on the X-ray generators in Room 8.237, Personnel: These procedures may only be carried out by Dr Mannan Ali. 1. Before commencing work possible hazards should first be considered. If there is any doubt then one of the above persons should be consulted at an early stage. 2. Use the override key to disable the interlocks and warn other persons in the room that you are doing so. 3. Install as much temporary shielding as you can around the beam in the area in which you are working. 4. Switch on the generator at minimum power and open the shutter. 5. Check the radiation field in the area where your hands will be. If the radiation is significantly above general background close the shutter and check/increase/reposition the temporary shielding. Open the shutter again and check the radiation field. 6. If the radiation field is now satisfactory increase the beam power to the working power which should be the minimum consistent with being able to carry out the work. 7. Check the radiation field again. If it is satisfactory proceed with the work. If it is not satisfactory rearrange the temporary shielding until it is. 8. Remove the override key to a safe place as soon as the procedure is completed. B.4.2 Protocol for diffractometers adjustment Protocol for making adjustments to one of the diffractometers on generator C in room 8.237 when the other diffractometer is in use Personnel: All radiation workers Normally the diffractometers are used with all of the interlocked doors closed. It is permissible, however, to make adjustments to the superstructures on one of the diffractometers whilst the other is in use. Care should be taken to avoid radiation exposure in these circumstances. 1. Make sure that the shutter on the equipment you are working on is clearly closed. 2. Open the appropriate interlocked door. 3. Mount a freestanding shield immediately in front of the beam exit aperture. 4. Check, using the minimonitor, the radiation field at all points where you will put your hands inside the half of the enclosure in which you are working. B.4. RULES FOR X-RAY GENERATORS IN ROOM 8-237 (DR MANNAN ALI) 33 5. If the radiation level is significantly higher than background level either (a) consult SRPS or Dr Mannan Ali or (b) wait until the other diffractometer is not in use and proceed with the generator switched off. 6. If the radiation is only slightly above background levels outside the enclosure you can proceed. 7. If you can proceed, carry out any operations as swiftly as possible. 8. When you have finished make a positive check that the shutter is still closed before you remove any temporary shielding. 9. Close the interlocked door. B.4.3 Protocol for the Wide Angle Camera Protocol for the Alignment of the Wide Angle Camera on Generator B in Room 8-237 Personnel: These procedures may only be carried out by Dr Mannan Ali. 1. Appropriate personal dosimeters must always be worn during this operation. 2. Use the override key to disable the interlocks and warn other persons in the room that you are doing so. 3. Switch on the generator at minimum power and open the shutter. 4. Check the radiation field in the area where your hands will be. If the radiation is significantly above general background, place temporary shielding in position to reduce it. 5. Mount a mirror behind the fluorescent screen so that the rear of the screen can be seen clearly from outside the enclosure. 6. Using just sufficient beam power to observe the beam spot observe the spot on the screen and adjust the camera mount using the two positioning screws on the tube shield mounting block. to maximise the beam intensity. Be very careful not to move your hand towards the film holder. Keep it as far as possible from the collimator exit in order to prevent inadvertent exposure. If any movement of the camera other than a slight realignment is required switch off the generator and check the whole assembly for correct mechanical alignment. 7. Remove the override key to a safe place as soon as the procedure is completed. B.4.4 Protocol for the Pole Figure Goniometer Protocol for the Alignment of the Pole Figure Goniometer on Generator B in Room 8.237. Personnel: These procedures may only be carried out by Dr Mannan Ali. 1. Use the override key to disable the interlocks and warn other persons in the room that you are doing so. 2. Before switching on the generator mount a fluorescent screen in the sample holder position. 3. Switch on the generator at minimum power and open the shutter. 34 APPENDIX B. RADIATION SAFETY 4. Check the radiation field in the area where your hands will be. If the radiation is significantly above general background, place temporary shielding in position to reduce it. 5. Using just sufficient beam power to observe the beam spot watch the spot on the screen and adjust the tube shield position using the two socket head adjusting screws on the base of the tube shield mounting column to maximise the beam intensity. Be very careful only to position your hands in the vicinity of the adjusting screws and do not lean into the cabinet. If any adjustment other than a slight realignment is required switch off the generator and check the whole assembly for correct mechanical alignment. 6. Remove the override key to a safe place as soon as the procedure is completed. N.B. A plastic divider panel should always be positioned between Airedale and Wharfedale. Interlock key must not be on display Dr Mannan Ali to keep it in a safe place. Red light to be positioned centrally at back. Appendix C Portable appliance test guidelines C.1 Testing of new or existing portable equipment (Mr Richard Oliver) All portable electrical equipment needs to be tested for electrical safety. 1. All new electrical or electronic items powered from the mains MUST be taken to Electronics Workshop before first use to be electrical safety tested. At this point each item receives an unique appliance number. 2. When the new item is brought for PAT testing a job request form should be filled in including the owner’s name and the location where it is used - Testing all items as they enter the department in Electronics Workshop maintains that all items have at least been tested once before being used. An appropriate test interval can be allocated to that item and the serial numbers of the items can be recorded for audit purposes on the database. 3. Existing items in the department (many of which have been through the PAT testing procedure several times from the early 1990s) will be tested according to the policy outlined below and merged into the new system. C.2 Policy for repeat tests of existing portable equipment (Mr Richard Oliver) Detachable power cords should have their own appliance number, consisting of the appliance number of the item it connects to + C and should be tested separately. The test sticker being placed on the plug face for ease of checking. Review of items that have passed PAT test several times, obtained from PATS database to allow for an increased test interval. Analysing the PATS database indicates that no new PCs failed PAT test and they did not fail subsequent tests. As these items are not really ’portable’ and most of the monitors are now LCD without the internal high voltage of a CRT screen, a 5-year interval would be most appropriate. The analysis shows a very low failure rate for instruments and general electrical equipment. There should be a sliding scale of test intervals as the test results mount for that equipment. A 2-year interval applied for new instruments, moving to 4 years for successive passes. The analysis shows that items of heavy usage, e.g. heaters, kettles, distribution boards, soldering irons etc., should be tested every year, as cables become damaged sockets become damaged and strain relief fail. These should remain at a 1-year interval. The teaching lab areas currently operates a sliding scale test interval up to 2 years for test instruments. As this equipment is operated by undergraduates it is suggested 35 36 APPENDIX C. PORTABLE APPLIANCE TEST GUIDELINES Colour Instrument Status Test Interval Red Failed or items not used Do Not Use (Label) Green Heavy use and regularly moved items e.g. heater, distribution leads, Lamps Moderate use and less frequently moved items Items that have gained several test passes at more frequent intervals e.g. Test instruments Light use or hardly ever moved items e.g. PC and IT items. 1 year Green Green 2 - 4 years 5 years Table C.1: Testing intervals and colour coding that a 2-year interval be the maximum interval for safety reasons. The PCs can have an extended interval. Attended two PAT testing courses run by different companies neither highlighted and problems with our testing strategy. The testing intervals and colour coding would be as outlined below in Table C.1. The Pass sticker contains the appliance number, initials of test person, date tested and next test date. These proposals require approval by faculty and university safety officers. Two new PAT testing kits have been purchased (tester and accessories) to provide 4 modern and 2 old testers for general use. Nominated persons from each group, along with technical staff have attend training courses. Nominated persons from each group to assist the students in ensuring rooms are fully tested. The ’Duty Officer’ regarding any issues from the test results and visual inspections, should be a member of Electronics Workshop. To make it easier for the user of the PAT tester, to know the most appropriate test for a given item and to carry out additional tests the names and settings of some of the standard pre installed tests have been changed. Appendix D Risk Assessment Form The risk assessment form, shown on page 39, is available as a Word document on the departmental web pages. The form shown here had to be modified and reduced in size to fit into the page. Changes to the form may have occurred since the printing of this book. Therefore please obtain an up to date copy of the Word document before starting a new risk assessment. As an alternative University of Leeds Safety Services provide software to record and maintain risk risk assessments (RIVO). 37 APPENDIX D.
