Introduction to Safe Working for Scientific Research Workers and Post Graduate Studentsat Sutton Bonington SARAH WATSON Assistant Safety Officer University Safety Office, ext 13301
Programme • Safety Why bother - Legislation Organisation Costs • General Precautions • Specific Hazards • Biological agents - Working to the Code
SAFETY - WHY BOTHER? • LEGAL DUTY • MORAL DUTY • ££££££££
Health and Safety at Work etc Act 1974 • Section 2 & 3 - Duties towards employees & othersEnsure, so far as is reasonably practicable, health, safety and welfare at work
Duties towards employees & people affected by undertaking [visitors/students] • provide and maintain equipment and procedures • use, handling, storage and transport of articles and substances • information, instruction, training and supervision • safe place of work and access/egress • welfare facilities - toilets, washing facilities

COST OF ACCIDENTS & WORK RELATED Ill HEALTH IN EDUCATION SECTOR ILL HEALTH £110 - 170 M ] INJURY £50M ] total £220 - 480M Non Injury Accidents £70-260 M ]
Postgraduates at Risk • 30 - 40 accidents per year • 50% handling sharps • Others • chemical exposure • slips and knocks • hot/cold contact • animals • manual handling
substances toxic/ carcinogens flammable Biological material Allergens noise vibration radiation[ ion/non-ion] electricity machinery pressure systems display screen equip manual handling mech. handling transport falls, falling objects slips, trips Typical Hazards
General Lab Safety • Risk Assessment • Training Needs/Records (Personal Dev Folder) • Fire • Accidents & First Aid • Glassware Safety • Housekeeping • Late Working • Unattended Experiments
Risk Assessment • Legal Requirement • Before work starts • Identify hazards • Look at controls in place • What improvements are needed? • Incorporate precautions in protocols See School Procedures
Training Records • Training log/Personal Dev Folder [RCOP] • Personal to you • Courses, procedures, equipment • Records who has trained you in these • Confirms attainment of competence to work unsupervised
Video • Practicing Safe Science
COSHH Risk assessment • Nature of hazard - harm that can be caused • Properties [toxicity, flammability] • quantity to be used • form • duration and frequency of use
Exposure Routes Exposure Routes – how can harm be caused? • Inhalation • Ingestion • Skin Contact/penetration- absorption, cuts
Decide on control measures • Eliminate or substitute, justify use. • Engineering - contain, extract [ FCs/MSCs] • Handling controls - e.g.avoiding aerosols • Personal protection • Information Training, supervision • Health surveillance/screening/vaccination Other considerations Storage Transport Disposal Emergencies - spills, first aid
PERSONAL PROTECTIVE EQUIPMENT [PPE] Last resort not first line of defence Lab Coats - must be worn in lab, fastened, remove before entering offices/clean areas Type - side fastening with cuffs - biological work Gloves - correct type for work - latex vs nitrile, - powder free - worker vs product protection Eye/ face - mandatory in certain areas, or subject to RA protection - personal - if not cleaning regime - suitable for purpose RPE - half masks, full masks, powered hoods - fit critical to protection Footware - no open toe/canvas shoes in labs/risk areas
Workplace Exposure Limits • Where there is exposure to a substance hazardous to health, control of that • exposure shall only be treated as adequate if • the principles of good practice for the control of exposure to substances hazardous to health are applied; • any workplace exposure limit approved for that substance is not exceeded • Given in ppm and mg/m3 • Time averaged concentration in air • Long term (8 hours) • Short term (15 minutes) - STEL
EXAMPLES OF SUBSTANCE WITH WEL [mg/m3] [mg/m3] 8hr 15mins Formaldehyde 2.5 2.5 Acrylamide 0.3 - Benzene 1.0 - Acetone 1210 3620 Bromine 0.66 2 Methanol 266 333 Toluene 191 574 Xylene 220 441 HW dust 5 - Grain dust 10 - If substance does not have WEL it does not mean it is safe - check MSDS/seek advice
Regulated Chemicals/substances • Schedule One Poisons • Very Toxic/carcinogens • Locked cabinet and restricted access • 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
Flammable Liquids • Flashpoint - temp. to form a flammable atmosphere • Flammable FP < 55C • Highly Flammable FP < 32 C • Extremely Flammable FP < 21 C • Flammability range - 1 to 15 % in air
Flammable Liquids • Precautions • avoid vapour release • store in solvent bin [ 50l max per room] • never store with acids/oxidising agent • stoppered labelled containers • minimum quantities on bench < 500ml • 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
Latex Allergy • latex can cause skin/respiratory sensitation. • 1% of population may react. • history of asthma, dermatitis, eczema, hayfever • Immediate • local or generalised spots and swelling (5-30 mins) • Delayed (peaks 24-48 hours then subsides) • red rash on back of hands / between the fingers • skin may become leathery and develop blisters • Seek advice from Occ Health if skin/resp symptoms • Latex alternatives & powder free gloves
Explosion in a Microwave Oven • Heating 300 ml media in 1 litre Duran bottle. • Cap swelled and sealed bottle which then exploded. • Debris hurled 3m across lab - unoccupied!!! • Use foam or Kim Wipe neck inserts.
Noise [Noise at Work Regs 1989] • Daily Noise Dose • exposure = intensity x duration • 3 dB = twice intensity thus half duration • Control Levels • <85 dB(A) - negligible risk • 85 - 90 dB(A) - small risk • inform of risk & HP available on request • >90 dB(A) - high risk - control at source compulsory HP audiometry [OHD via SSO]
Pressure Systems • Stored energy • Steam • Gas or vapours > 0.5 bar • Boilers, autoclaves, air receivers, reactors • 250 bar/litre for system • Requirements • Design/construction • safe operating limits • Written scheme for examinations • Written operating instructions • Notify Estate Office
Lasers/Ionising Radiation • Separate Introductions • Local rules for safe use • Health/medical checks
LABORATORY U.V SOURCES [280nm - 400nm] Examples: Transilluminators, gel docs, hand held lamps Biocidal lamps, Mercury vapour lamps [uv spec] Health Effects: Sunburn, cancer, eye damage Safety precautions Interlocks/enclosure UV opaque shielding UV opaque visor Cover exposed skin Restrict access to area Associated hazards : Ethidium Bromide Mercury
Electricity • 50 V AC can KILL • Electricity at Work Regulations • design, construction, maintenance • earthing, fusing, isolation, insulation • live working [special precautions] • University Code of Practice • Periodic inspection/testing - usually annual - sticker? • User visual checks plugs, cable & socket, evidence of overheating, casing • Report all defects • All repairs by workshops • Avoid - overloading sockets/ [max 3kW/multiboard] - long extension leads[trips /heating ]
Cryogenic Liquids • Asphyxiation • <18% O2 (spills > 143ml LN/m3 : 1:700) • confined spaces, DO NOT TRAVEL IN LIFT • Cold Burns • eye protection - goggles/visors/specs • hands - non absorbent insulated gloves eg leather. Sleeves over ends/securely banded. • Feet - closed shoes, trousers over • tongs/forceps • Ice Plug formation • Oxygen enrichment • Exploding vials • Transport by road- DON’T - very hazardous • Use cardice
FIRE - WHAT YOU NEED TO KNOW! • Procedure • Call point location • Escape route(s) • Assemply point • Appliances • fire warden/monitor • Token system
First Aid and Accidents • Report all accidents, health issues and near misses • Be aware of how to summon a first aider • Be aware of how to summon the emergency services
Fire Procedure • 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
Fire Procedures • On hearing alarm - leave building by nearest exit - closing doors/widows - go to assembly • Fire Tokens • Small searchable area • Confirm to Evacuation Co-ordinator • Notify if known false alarm - 8888
