4 Safety – why bother? University Safety Office - New Researchers Talk Legal Duty Moral Duty ££££££££ Reputation

5 Health and Safety at Work etc Act 1974 n Section 2 & 3 - Duties towards employees & others n Ensure, so far as is reasonably practicable, health, safety and welfare at work University Safety Office - New Researchers Talk

6 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

15 Accidents cost money COST OF ACCIDENTS & WORK RELATED Ill HEALTH IN EDUCATION SECTOR ILL HEALTH £ M] INJURY £50M]total £ M Non Injury Accidents £ M] University Safety Office - New Researchers Talk

16 Postgraduates Incidents n Typically accidents reported each year n 50% handling sharps n Others –chemical exposure –slips and knocks –hot/cold contact –animals –manual handling University Safety Office - New Researchers Talk

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

18 Risk Assessment Legal Requirement Carried out before work starts 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 Hi, Im David and Im invincible

19 Risk Assessment University Safety Office - New Researchers Talk 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

20 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

21 Accidents and First Aid n Report all incidents whether injuries or ill- health (to your line manager/safety officer) n Know how to call a first aider n Know how to call for an ambulance –8888 or n 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

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

23 Fire Procedure If you discover a fire –Raise the alarm –Dial 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

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

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

26 Video n Practicing Safe Science University Safety Office - New Researchers Talk

27 Typical Hazards in the Research Environment n substances –toxic/ carcinogens –flammable –biological material –allergens n noise n vibration n radiation n electricity n machinery n pressure systems n display screen equip n manual handling n mech. handling n transport n falls, falling objects n slips, trips n fire n Lasers n nanoparticles University Safety Office - New Researchers Talk 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

28 Substances related hazards n Chemicals n Flammables n Carcinogens n Nanoparticles n Poisons University Safety Office - New Researchers Talk

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

30 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

31 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

32 Hazardous propertyExample Irritant, Harmful,Ammonia, SensitisingGlutaraldehyde, isocyanates, animal allergens, latex Toxic/carcinogenic, Mutagenic, Teratogenic Acrylamide, MNU, EthBr, cytotoxic drugs CorrosiveString acids & bases InfectiousBacteria, virus FlammableAlcohol, acetone ExplosiveHexane, hydrogen Oxidising Potassium permanganate, Hydrogen peroxide Ecotoxic Mercury University Safety Office - New Researchers Talk

33

34 Workplace Exposure Limits University Safety Office - New Researchers Talk 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

35 Examples of Substances with WELs [mg/m 3 ] [mg/m 3 ] 8hr 15mins Formaldehyde Acrylamide0.3 - Benzene1.0 - Bromine Methanol Toluene Xylene Acetone If substance does not have WEL it does not mean it is safe - check MSDS/seek advice University Safety Office - New Researchers Talk

36 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

37 Nanoparticles One or more external dimensions in the order of 100 nm or less ie: < 0.1 micrometre / micron University Safety Office - New Researchers Talk MSDS for micron-sized particles of a substance does not necessarily apply to nanoparticles – we MUST take the precautionary approach and avoid exposure

38 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): Fume Cupboards University Safety Office - New Researchers Talk

39 THE GOOD University Safety Office - New Researchers Talk

41 THE UGLY

42 Is this good practice??? University Safety Office - New Researchers Talk

43 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 - gloves - correct type for the work Protection Eye/ face- glasses, goggles, visors – depending Protectionon hazard Respiratory - half masks, full masks, powered Protectionhoods - fit critical to protection Foot- no open toe/canvas shoes in Protectionlabs/risk areas. Safety footwear depending on hazards University Safety Office - New Researchers Talk

44 Regulated Chemicals/Substances n Schedule One Poisons –Very Toxic/carcinogens –Locked cabinet and restricted access n Chemical/Biological Warfare Materials –Sarin, Soman, Tabun, VX –Sulphur & Nitrogen Mustards –Lewisites –Saxitoxin, Ricin, –Schedule 5 pathogens [ e.g Vibrio Cholera] –Toxins e.g. Botox, Tetrodotoxin, Verotoxin, Staphlococcal Toxins, Conotoxin University Safety Office - New Researchers Talk
