  • ProgrammeSafety Why bother - LegislationOrganisationCostsGeneral PrecautionsSpecific HazardsBiological agents - Working to the Code


  • Health and Safety at Work etc Act 1974Section 2 & 3 -Duties towards employees & others Ensure, 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 proceduresuse, handling, storage and transport of articles and substances information, instruction, training and supervisionsafe place of work and access/egresswelfare facilities - toilets, washing facilities

  • LegislationGeneralFirst aidFireNoiseLeadAsbestosHighly flammable liqIonising RadiationsCoshhGenetic modificationElectricityPressure systemsWork equipmentPPEManual HandlingDisplay Screen Equip

  • ResponsibilitiesAcademic SupervisorsIdentify hazards & risksWritten proceduresEnsure effective supervision & training to full competencyDemonstrators [employees]Understand the practical Know the hazards/precautionsBe ready to interveneAction in case of accidents

  • RESPONSIBILITIES [S. 7 & 8 HSAWA]INDIVIDUALS - THAT MEANS YOU- Work safely- Follow instructions & rules- Dont endanger others- Dont misuse safety equipment- Report problems /unsafe situations

  • General Lab SafetyRisk AssessmentTraining Needs/Records (Personal Dev Folder)FireAccidents & First AidGlassware SafetyHousekeepingLate WorkingUnattended Experiments

  • Risk AssessmentLegal RequirementBefore work startsIdentify hazardsLook at controls in placeWhat improvements are needed?Incorporate precautions in protocolsSee School Procedures

  • Training Records

    Training log/Personal Dev Folder [RCOP]Personal to youCourses, procedures, equipment Records who has trained you in theseConfirms attainment of competence to work unsupervised

  • VideoPracticing Safe Science

  • COSHH Risk assessmentNature of hazard - harm that can be caused Properties [toxicity, flammability]quantity to be usedformduration and frequency of use

  • Hazardous propertyExampleIrritant, Harmful,Ammonia, SensitisingGlutaraldehyde, isocyanates, animal allergens, latexToxic/carcinogenic, Mutagenic, TeratogenicAcrylamide, MNU, EthBr, cytotoxic drugsCorrosiveString acids & basesInfectiousBacteria, virusFlammableAlcohol, acetoneExplosiveHexane, hydrogenOxidisingPotassium permanganate, Hydrogen peroxideEcotoxicMercury

  • Exposure RoutesExposure Routes how can harm be caused?

    InhalationIngestionSkin Contact/penetration- absorption, cuts

  • Decide on control measuresEliminate or substitute, justify use.Engineering - contain, extract [ FCs/MSCs]Handling controls - e.g.avoiding aerosolsPersonal protectionInformation Training, supervisionHealth surveillance/screening/vaccination

    Other considerations StorageTransportDisposalEmergencies - spills, first aid

  • PERSONAL PROTECTIVE EQUIPMENT [PPE]Last resort not first line of defenceLab Coats- must be worn in lab, fastened, remove before entering offices/clean areasType- side fastening with cuffs - biological workGloves - correct type for work- latex vs nitrile, - powder free- worker vs product protectionEye/ face- mandatory in certain areas, or subject to RAprotection- personal - if not cleaning regime- suitable for purposeRPE- half masks, full masks, powered hoods- fit critical to protectionFootware- no open toe/canvas shoes in labs/risk areas

  • Workplace Exposure Limits Where there is exposure to a substance hazardous to health, control of thatexposure 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 airLong term (8 hours)Short term (15 minutes) - STEL

  • EXAMPLES OF SUBSTANCE WITH WEL [mg/m3] [mg/m3] 8hr 15mins

    If substance does not have WEL it does not mean it is safe - check MSDS/seek advice

  • Regulated Chemicals/substancesSchedule One PoisonsVery Toxic/carcinogensLocked cabinet and restricted accessChemical/Biological Warfare Materials sarin, soman, tabun, VXSulphur & Nitrogen MustardsLewisitesSaxitoxin, Ricin,Schedule 5 pathogens [ e.g Vibrio Cholera]Toxins e.g. Botox, Tetrodotoxin, Verotoxin, Staphlococcal toxins, Conotoxin

  • Flammable LiquidsFlashpoint - temp. to form a flammable atmosphereFlammableFP < 55CHighly FlammableFP < 32 CExtremely FlammableFP < 21 CFlammability range - 1 to 15 % in air

  • Flammable LiquidsPrecautionsavoid vapour releasestore in solvent bin [ 50l max per room]never store with acids/oxidising agentstoppered labelled containersminimum quantities on bench < 500ml enclosed carriers for Winchestersspark-proof fridgesbeware of - static build up on large scale decanting - Flammable atmospheres /heavy vapoursknow spillage procedure - clear up immediately

  • Latex Allergylatex can cause skin/respiratory sensitation.1% of population may react.history of asthma, dermatitis, eczema, hayfeverImmediate 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 blistersSeek advice from Occ Health if skin/resp symptomsLatex alternatives & powder free gloves

  • Explosion in a Microwave OvenHeating 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 Doseexposure = intensity x duration3 dB = twice intensity thus half durationControl Levels90 dB(A) - high risk - control at source compulsory HP audiometry [OHD via SSO]

  • Pressure SystemsStored energySteamGas or vapours > 0.5 barBoilers, autoclaves, air receivers, reactors250 bar/litre for systemRequirementsDesign/constructionsafe operating limitsWritten scheme for examinationsWritten operating instructionsNotify Estate Office

  • Lasers/Ionising RadiationSeparate IntroductionsLocal rules for safe useHealth/medical checks

  • LABORATORY U.V SOURCES [280nm - 400nm]Examples:Transilluminators, gel docs, hand held lampsBiocidal lamps, Mercury vapour lamps [uv spec]Health Effects:Sunburn, cancer, eye damage

    Safety precautionsInterlocks/enclosureUV opaque shieldingUV opaque visorCover exposed skinRestrict access to areaAssociated hazards : Ethidium Bromide Mercury

  • Electricity50 V AC can KILLElectricity at Work Regulationsdesign, construction, maintenanceearthing, fusing, isolation, insulationlive working [special precautions]University Code of PracticePeriodic inspection/testing - usually annual - sticker?User visual checks plugs, cable & socket, evidence of overheating, casingReport all defects All repairs by workshopsAvoid - overloading sockets/ [max 3kW/multiboard] - long extension leads [trips /heating ]

  • Cryogenic LiquidsAsphyxiation 143ml LN/m3 : 1:700)confined spaces, DO NOT TRAVEL IN LIFTCold Burns eye protection - goggles/visors/specshands - non absorbent insulated gloves eg leather. Sleeves over ends/securely banded.Feet - closed shoes, trousers overtongs/forcepsIce Plug formationOxygen enrichmentExploding vialsTransport by road- DONT - very hazardousUse 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 AccidentsReport all accidents, health issues and near missesBe aware of how to summon a first aiderBe aware of how to summon the emergency services

  • Fire ProcedureRaise the alarmDial 8888 [0115 951 8888]Leave the building by nearest exitClose doors and windows behind youReport to assembly pointOnly use extinguisher if:Small, contained fireConfidentClear exit route

  • Fire ProceduresOn hearing alarm - leave building by nearest exit - closing doors/widows - go to assemblyFire TokensSmall searchable areaConfirm to Evacuation Co-ordinatorNotify if known false alarm - 8888
