Safety – why bother? • Legal Duty • Moral Duty • ££££ • Reputation University Safety Office - New Researchers Talk
Legal Duties upon the University Duties towards employees AND people affected by undertaking (students/visitors): – – – Workplace – access, egress, circulation Equipment, tools, substances Procedures Training and supervision Welfare - toilets, washing facilities So far as is reasonably practicable University Safety Office - New Researchers Talk
A lot of legislation applies to research at the University – just a few examples…… n n n n General First aid Fire Noise Lead Asbestos Highly flammable liq Ionising Radiations n n n n COSHH Genetic modification Electricity Pressure systems Work equipment PPE Manual Handling (DSE) Computers University Safety Office - New Researchers Talk
University Organisation University Safety Office - New Researchers Talk

Chemistry, Uo. N - Incompatible Chemicals in Waste Solvent University Safety Office - New Researchers Talk
Postgraduates Incidents n Typically 30 - 40 accidents reported each year n 50% handling sharps Others n – – – chemical exposure slips and knocks hot/cold contact animals manual handling University Safety Office - New Researchers Talk
General Lab / Workshop Safety n n Risk Assessment Training Needs / Competency Specific Hazards Miscellaneous – – – Glassware Safety Housekeeping Late Working Unattended Experiments Emergency Procedures University Safety Office - New Researchers Talk
Risk Assessment Legal Requirement “Hi, I’m David and I’m Carried out before work starts invincible” n Identify hazards n Look at controls in place n Evaluate the risk (likelihood) n What improvements are needed? Incorporate precautions in SOPs See School Procedures University Safety Office - New Researchers Talk
Risk Assessment n HAZARD – the potential of something to cause harm n RISK – the likelihood of an event occurring which will allow the hazard to occur Think of an activity outside of the University 1. List the hazards 2. List the control measures that reduce the risk University Safety Office - New Researchers Talk
Training vs Competence n Attending training is one thing, being competent to carry out an activity is another. n You should have evidence of both training and achieving competence – Some schools use postgraduate supervisory requirements form (PSRF) personal to you and confirms what supervision you require – Keep a record of all • External courses • University courses • Lab-specific training (procedures and/or equipment) – Records should show who has trained you and when University Safety Office - New Researchers Talk
Accidents and First Aid n n Report all incidents whether injuries or illhealth (to your line manager/safety officer) Know how to call a first aider Know how to call for an ambulance – 8888 or 0115 9518888 It may be you, it may be a friend, it may be nothing to do with the work – know how to help University Safety Office - New Researchers Talk
Fire Safety – What you should know • Evacuation Procedure • Call point location • Escape route(s) • Assembly point University Safety Office - New Researchers Talk
Fire Procedure If you discover a fire – Raise the alarm – Dial 8888 (0115 951 8888) – Leave the building by nearest exit • Close doors and windows behind you • Report to assembly point – Only use extinguisher if: • Small, contained fire • Confident • Clear exit route University Safety Office - New Researchers Talk
Fire Procedure On hearing alarm - leave building by nearest exit - closing doors/widows - go to assembly n n Notify if known false alarm – 8888 (Mobile 0115 9518888) University Safety Office - New Researchers Talk
Fire Extinguishers Water – all red Foam – cream band Dry Powder – blue band CO 2 black band University Safety Office - New Researchers Talk
Typical Hazards in the Research Environment n n n substances – toxic/ carcinogens – flammable – biological material – allergens noise vibration radiation electricity machinery n n n n n pressure systems display screen equip manual handling mech. handling transport falls, falling objects slips, trips fire Lasers nanoparticles The following slides give a summary of the key precautions expected to be in place. Further detail, specific to your research, must be obtained locally University Safety Office - New Researchers Talk
Substances related hazards n n n Chemicals Flammables Carcinogens Nanoparticles Poisons University Safety Office - New Researchers Talk
Hazardous Substances n n n Chemicals Biological Agents Dusts Gases COSHH – Control of Substances Hazardous to Health University Safety Office - New Researchers Talk
COSHH Regulations n Look at the nature of hazard - harm that can be caused • • Properties [toxicity, flammability] Quantity to be used Form (solid, liquid, gas) Duration and frequency of use University Safety Office - New Researchers Talk
Routes of exposure n Exposure Routes - how can harm be caused – Inhalation – Ingestion – Skin Contact/penetration • Absorption, • Sharps • Defective skin barrier University Safety Office - New Researchers Talk
Hazardous property Example Irritant, Harmful, Ammonia, Sensitising Glutaraldehyde, isocyanates, animal allergens, latex Toxic/carcinogenic, Mutagenic, Acrylamide, MNU, Eth. Br, Teratogenic cytotoxic drugs Corrosive String acids & bases Infectious Bacteria, virus Flammable Alcohol, acetone Explosive Hexane, hydrogen Oxidising Potassium permanganate, Hydrogen peroxide Ecotoxic Mercury University Safety Office - New Researchers Talk

Workplace Exposure Limits • Set for some hazardous substances • Must not be exceeded • Limits given in ppm and mg/m 3 • Time averaged concentration in air • Long term (8 hours) • Short term (15 minutes) - STEL University Safety Office - New Researchers Talk
Examples of Substances with WELs [mg/m 3] 8 hr [mg/m 3] 15 mins Formaldehyde Acrylamide Benzene Bromine 2. 5 0. 3 1. 0 0. 66 2. 5 2 Methanol Toluene 574 Xylene 266 333 220 441 Acetone 1210 3620 191 If substance does not have WEL it does not mean it is safe - check MSDS/seek advice University Safety Office - New Researchers Talk
COSHH Assessment Decide on control measures – – – Eliminate or substitute, justify use. Engineering - contain, extract (FCs/MSCs) Personal protection Training, supervision Health surveillance/screening/vaccination Other considerations - Storage - Transport - Disposal - Emergencies – leaks, spills - Nanoparticles University Safety Office - New Researchers Talk
Nanoparticles One or more external dimensions in the order of 100 nm or less ie: < 0. 1 micrometre / micron MSDS for micron-sized particles of a substance does not necessarily apply to nanoparticles – we MUST take the precautionary approach and avoid exposure University Safety Office - New Researchers Talk
Fume Cupboards A means of containing or extracting hazardous fumes/vapours/aerosols away from the operator, to be safely discharged to the atmosphere. SAFE WORKING • Check it is working • Position of Equipment • Safe working area • Control air movement /external forces • Avoid heat sources • Minimise sash opening • Unattended experiments – leave information • Clean after use! • Animated demonstration (3 minutes): http: //www. youtube. com/watch? v=A 4 AHx.

THE UGLY University Safety Office - New Researchers Talk
Personal Protective Equipment (PPE) Last resort not first line of defense Lab Coats - must be worn in lab, remove before entering offices/clean areas Hand Protection - gloves - correct type for the work Eye/ face Protection - glasses, goggles, visors – depending on hazard Respiratory Protection - half masks, full masks, powered hoods - fit critical to protection Foot Protection - no open toe/canvas shoes in labs/risk areas. Safety footwear depending on hazards University Safety Office - New Researchers Talk
Flammable Liquids Flash Point – temp to form a flammable atmosphere Precautions – – – – avoid vapour release never store with acids/oxidising agent stoppered labelled containers minimum quantities on bench < 500 ml store in solvent cupboard [50 l max per room] enclosed carriers for Winchesters spark-proof fridges beware of - static build up on large scale decanting - flammable atmospheres /heavy vapours – know spillage procedure - clear up immediately University Safety Office - New Researchers Talk
