1 An Introduction to CoSHH (Control of Substances Hazardous to Health Regulations,2004)
2 What is a hazardous substance under the Regulations? Substances & mixtures classified as dangerous under CHIP – (Chemicals (Hazard Information and Packaging for Supply) Regulations 2008 )Substances with WELs (Workplace exposure limits)Biological agentsSome dusts, especially in high concentrationsOther substances of comparable hazard
3 What are NOT hazardous substances under CoSHH? Lead and Asbestos (separate regulations)Substances only hazardous due to:Radio-activitySimple asphyxiantsHigh pressure or extremes of temperatureBiological agents not connected with workEg Swine flu or catching a cold from a colleagueLabels are a good guide!
4 What must an employer do? Eliminate or reduce risks from hazardous substancesThis is achieved by:Risk assessmentControl measuresMonitoring health & exposure if necessaryInformation, training and supervision
5 What must an employee do? Take reasonable care of our own safety and not endanger othersCooperate with our employerMake full and proper use of control measureJust reiterating our duties under HSAW
6 Step 1 : Risk Assessment for CoSHH Identify the hazardous substance(s) egChemicalsBiological materialsMixturesProprietary productsReaction products and intermediates
7 Step 1 : Risk Assessment for CoSHH New International Hazard Symbols Danger Flammable Oxidiser
8 Step 1 : Risk Assessment for CoSHH New International Hazard SymbolsExplosive Corrosive Compressed orliquefied gas
9 Step 1 : Risk Assessment for CoSHH New International Hazard SymbolsAquatic Warning Sensitiser, carcinogen,Toxicity mutagen or teratogen
10 OTHER SYMBOLS YOU MIGHT SEE – WHAT DO THEY MEAN?

12 Step 1: Other sources of information Use available data eg.Data sheets & labelsWorkplace exposure limits (WELs) – see Safety Services web siteOn-line databasesPrevious experience & publications(Especially for novel products)
13 Step 1 Decide who is at risk and how StaffStudentsOthersConsider their current training (if any) and their background
14 Step 1: Decide who is at risk and how InhalationSkin or eye contaminationIngestionInjection
15 Step 1: Evaluate the Risk Factors to Consider:ToxicityForm (gas, spray, dust, liquid, solid)SolubilityAmount (weight &/or volume)Nature of the operationLength of exposureNumber of people involvedOR
16 Step 2: Decide on Control Measures Control exposure in proportion to risk by using the hierarchy of controls.Personal protective equipment should be a last resort as the prime means of control?
17 Step 3: Use of Control Measures (1) Replace substance with a safer alternativeEg use a lower hazard disinfectant rather than bleach (irritant) if it will do the job adequately
18 Step 3: Use of Control Measures (2) Use the material in a safer form eg:Use water-based paint instead of solvent-based paintBuy hazardous materials in pre-weighed sachets rather than having to measure & make-up from bulk quantities
19 Step 3: Use of Control Measures (3) Control the operation egIsolate the workControl at sourceFume cupboardLocal exhaust ventilationReduce the number of workersReduce the frequency
20 Step 3: Use of Control Measures (4) Personal protective equipment as a last resort:Protects only the worker & not others in the roomTraining & maintenance requiredOften not very comfortable
21 Step 3: Use of Control Measures (5) Good laboratory techniques is vital eg.LabellingCorrect substance storageWarning signs where appropriateCleanliness & tidinessCorrect waste disposal
22 Step 4: Maintenance of control measures Must be kept in good repair & working properlyRegular simple checks on airflowLEV & fume cupboards must have engineering checks every 14 monthsRecords kept for 5 years
23 Step 5: Monitor Exposure Measure concentrations where assessment concludes that:There is a serious risk if controls failExposure limits may be exceededControl measures may not be working properlyEmployees are involved in certain specific work in Schedule 5 (unlikely in the University apart from possibly use of vinyl chloride monomer)Records must be kept for 5 years
24 Step 6: Health Surveillance Only required if:Significant exposure of Schedule 6 processes (apart from vinyl chloride use, these are all manufacturing processes)Likelihood of exposure to substances linked to specific diseases but only if:There is a reasonable likelihood that this will occurIt is actually possible to detect the disease or effectRecords to be kept for 40 years
25 Step 7: Derive safe working procedures Preparation phase(eg weighing out)The process itselfSafe waste disposalEmergency proceduresSpillageFireFirst aid
26 Step 8: Workers must have adequate: InformationInstructionTrainingSupervisionThis will include the procedures themselves and what to do in an emergency
27 Step 9: Check and review: Are the control measures adequate?Are they working correctly?Is everyone aware of how to use them?Have you the necessary equipment to deal with an emergency or malfunction?
