5Why do I need a risk assessment? It’s the LawHealth and Safety at Work etc. Act 1974The Management of Health and Safety at Work Regulations 1999Isn’t it the right thing to do?It could protect and save YOU and me
6Types of Risk Assessment Qualitative: Object probability estimate based upon known risk information applied to the circumstances being consideredQuantitative: This type is subjective, based upon personal judgment backed by generalised data risk. The two types of risk assessment (qualitative and quantitative) are not mutually exclusiveQualitative assessments are easier to make and are the ones required for legal purposesWe use Quantitative in every day activities.
8The difference… Hazard Risk Is the potential of a substance or process to cause harmRiskIs the probability of a hazard actually causing harm
9Example Hazard of Asbestos Risk of inhaling Asbestos fibre’s causes mesothelioma (lung cancer)Risk of inhaling Asbestos fibre’sminimal if asbestos board is in good condition. However, risk is greater if the asbestos board is in poor condition or is broken
10Hazards A Hazard is any substance or process which may cause harm In order to conduct a risk assessment it is necessary to consider any hazards that may be present in your workplaceFor exampleDo you use any hazardous substances…e.g. paints, solvents, acids?Is it a noisy environment?Do you work at height?Does your process generate any particles or gases?Do you use display screen equipment?

13Where to find information The person who may be affectedAccident Reports/HistoryMaterial Safety Data Sheets (MSDS)Container labelsTrade journalsRisk phrasesHSE
14Safety Data Sheets Materials Safety Data Sheets Includes details on: Name & Address of supplierChemical Composition/IngredientsPhysical DataExposure Controls & PPEFire Fighting InformationFirst Aid Advice
15Journals Container labels & trade journals Container labels will often list the “ingredients” in a productIndustry trade journals may provide useful information on various common hazards
16Risk PhrasesThese are definitions of chemicals – as detailed in CHIP 2 RegulationsExamples:R1 - explosive when dryR26 - very toxic by inhalationR35 - causes severe burnsR42 - may cause sensitisation by inhalationR43 - may cause sensitisation by skin contactR49 - may cause cancer by inhalation
17Risks A risk is the probability of a hazard actually causing harm The level of risk can be different for different workers, for exampleexpectant motherspeople with disabilitiesnew workersyoung workersFor respiratory and hearing hazards, the risk associated is usually assessed by the level of exposure experienced by an individual compared with occupational limits.
18AssessmentThe level of exposure to a hazard is critical when conducting a risk assessmentThis will determine whether the hazard is a threatMonitoring methods include; passive badge samplers, noise meters and personal pump monitoringThis can indicate a personal dose, which is the best assessment of the potential risk to an individualOther assessment methods also exist. E.g. HSG53, HSE Guide to Selecting RPE.
19COSHHWELs are occupational exposure limits set under CoSHH (Control of Substances Hazardous to Health)They are concentrations of hazardous substances in the air, averaged over a specified period of timeTwo time periods are used, short term (15 minutes) and long term (8 hours)Employers have a legal duty under CoSHH to control exposure to chemicals hazardous to health.
21Could you…Alter the work process in order to eliminate or reduce the risk of a hazard?Substitute a hazardous substance for a less hazardous chemical?Elimination/substitution should be your first consideration when aiming to reduce risk, but this may not always be a viable option.
22ControlsIf you are not able to eliminate the hazard, you might consider other controlscould better ventilation reduce exposure to a hazardous particle?could non-slip matting be fitted to reduce the risk of falls?could luminous tape be fitted to reduce the risk of tripping?Some cases, however, the hazard may still present a significant risk after these controls have been put in place. In this case you might consider PPE.
23Common ErrorsHazard lists are not kept up to date or people are unaware of the hazardsNo training is provided for those who need to be aware of and use the risk assessmentThe Risk Assessment is carried out by a person not deemed as competentThe Risk Assessment becomes out of dateThe person who is at risk of harm or injury has never seen the risk assessmentControl measures are by-passed
24Risk AssessmentA risk assessment is an information gathering exercise about:Hazards, Risks and ControlsRequires information on:SubstancesWork processes (location, duration, equipment)Assessments of the levels of exposureEvaluations of control measures
25Summary Employers must identify hazards Employers must assess the Risks – A Risk AssessmentA Risk is the probability of a Hazard actually causing harmA Risk Assessment shouldidentify hazardsconsider the riskscontrol the risksPPE is the last resort or used as a control measuresThe person(s) who might be harmed, or those expected to follow the risk assessment should be part of creating it, understand it, and/or be trained in/with it.
