14. General Lab / Workshop Safety • Risk Assessment • Training Needs / Competency • Specific Hazards • Miscellaneous • Glassware Safety • Housekeeping • Late Working • Unattended Experiments • Emergency Procedures University Safety Office - New Researchers Talk

15. Risk Assessment Legal Requirement Carried out before work starts • Identify hazards • Look at controls in place • Evaluate the risk (likelihood) • What improvements are needed? Incorporate precautions in SOPs See School Procedures “Hi, I’m David and I’m invincible” University Safety Office - New Researchers Talk

16. Risk Assessment • HAZARD • the potential of something to cause harm • RISK • the likelihood of an event occurring which will allow the hazard to occur Think of an activity outside of the University • List the hazards • List the control measures that reduce the risk University Safety Office - New Researchers Talk

17. Training vs Competence • Attending training is one thing, being competent to carry out an activity is another. • 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

18. Accidents and First Aid • Report all incidents whether injuries or ill-health (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

19. Fire Safety – What you should know • Evacuation Procedure • Call point location • Escape route(s) • Assembly point University Safety Office - New Researchers Talk

20. 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

21. Fire Procedure On hearing alarm - leave building by nearest exit - closing doors/widows - go to assembly • Notify if known false alarm – 8888 • (Mobile 0115 9518888) University Safety Office - New Researchers Talk

22. Fire Extinguishers Water – all red Foam – cream band Dry Powder – blue band CO 2 black band University Safety Office - New Researchers Talk

23. Typical Hazards in the Research Environment • substances • toxic/ carcinogens • flammable • biological material • allergens • noise • vibration • radiation • electricity • machinery • 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

24. Substances related hazards • Chemicals • Flammables • Carcinogens • Nanoparticles • Poisons University Safety Office - New Researchers Talk

25. Hazardous Substances • Chemicals • Biological Agents • Dusts • Gases • COSHH – Control of Substances Hazardous to Health University Safety Office - New Researchers Talk

26. COSHH Regulations • 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

27. Routes of exposure • Exposure Routes - how can harm be caused • Inhalation • Ingestion • Skin Contact/penetration- • Absorption, • Sharps • Defective skin barrier University Safety Office - New Researchers Talk

30. Workplace Exposure Limits • Set for some hazardous substances • Must not be exceeded • Limits given in ppm and mg/m3 • Time averaged concentration in air • Long term (8 hours) • Short term (15 minutes) - STEL University Safety Office - New Researchers Talk

31. Examples of Substances with WELs [mg/m3] [mg/m3] 8hr 15mins Formaldehyde 2.5 2.5 Acrylamide 0.3 - Benzene 1.0 - Bromine 0.66 2 Methanol 266 333 Toluene 191 574 Xylene 220 441 Acetone 1210 3620 If substance does not have WEL it does not mean it is safe - check MSDS/seek advice University Safety Office - New Researchers Talk

32. 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

33. NanoparticlesOne 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

34. 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=A4AHxLnByts University Safety Office - New Researchers Talk
