The National Occupational Health and Safety Commission released the Kerr Report in 1996. This report estimates 2300 Australian workers a year die as a result of exposure to workplace hazardous substances. Many others become sick, debilitated or disfigured.Working with Chemicals This session covers: Working with Chemicals This session covers Philosophy Legislative Context Content ApplicationPhilosophy: Philosophy Identify the HAZARD Assess the RISK Institute Appropriate CONTROLSHazard or Risk?: Hazard or Risk? This is a HAZARD Hazards may cause a Risk to health or safety: Hazards may cause a Risk to health or safety This is a RISKSlide7: Hazard means the potential to cause injury or illness and can apply to substances, methods or machines. Risk means the probability and consequences of occurrence of injury or illness. Risk will depend on such factors as the nature of the hazard, the degree of exposure and individual characteristics.Eliminate the Hazard at its Source: Eliminate the Hazard at its Source When you know that you are dealing with a hazard, you can take action to reduce the risk.Substitute for something less hazardous: Substitute for something less hazardous If it is not possible to eliminate the hazard, it may be possible to substitute it for something less hazardousEngineering: Engineering It may be possible to bring in engineering controls such as exhaust ventilation hoods or isolation methods.How effective do you think this is?: How effective do you think this is? This approach does not improve safety by much, but it does let you know what the sudden pain is and why you are about to die.How effective would this be?: How effective would this be? Look Out serpent in the dunesInformation Provision: Information Provision Providing information in itself will not improve safety, it must be accompanied by actions. If the information cannot be understood (the previous slide says “look out serpent in the dunes”) it cannot be acted on. MSDS are complicated and the average person may be confused by much of the content.

The question that needs to be answered is : “What is the substance and are you exposed?”Identify the Hazard: Identify the Hazard Which one of these is a workplace snake? The legislation is framed to help us find out.Legislative Framework: Legislative Framework Act Regulations Approved Codes of Practice Australian Standards Guidance Notes Reducing obligationSlide20: Legislative Context Blue and yellow are mandatory requirements.

Very Toxic Toxic Harmful Corrosive Irritant Sensitising Carcinogenic Mutagenic Toxic to reproduction Is it on the Worksafe list? Does it fit the Worksafe Criteria? (Suppliers only) Does it say so on the label? Does the MSDS give cause for concern? Is there other information that gives cause for concern?Information Provision: Information Provision The Hazardous Substances Legislation requires suppliers to provide material safety data sheets (MSDS) to employers. These MSDS contain information on the nature of the substance, how to use it safely and its health effects. The label and the MSDS will let you know if there is a hazard.Information Provision: Information Provision Some employers are using Third Party electronic data bases. This action sits outside of the legislation. Good management of chemicals is to be encouraged. However, these third party sources do not replace the legal requirement to have the original MSDSLabels: Labels Suppliers Manufacturers, Importers, Wholesalers Distributors (Not Retailers) must label containers of hazardous substances in accordance with the Worksafe standard format (found in the Approved Code of Practice) Employers to ensure that: containers remain correctly labelled any container into which the hazardous substance is decanted is appropriately labelled identify contents of pipes/enclosed systems (found in the Approved Code of Practice)What is a Label: What is a Label Outside face of the container English language Durable print Legible lettering size and style Firmly secured and printed in a contrasting colour to the background Remain labelled until container no longer contains the substance Not to be removed, defaced, modified or alteredMSDS: MSDS MANUFACTURERS AND IMPORTERS: Produce, Revise, Review, Provide to National Repository MANUFACTURERS IMPORTERS, WHOLESALERS & DISTRIBUTORS: Ensure supply on first purchase (unless going to a retailer for sale in packages less than 30kg or 30L) Ensure supply on request EMPLOYERS: Obtain on or before first supply Ensure one held for each haz substance Ensure they are readily accessible Ensure they are not altered except to reformat overseas versionContent of an MSDS: Content of an MSDS Statement of whether this is a hazardous substance Supplier Details including emergency phone Clearly Identify the Substance Recommended Uses Describe its Physical and Chemical Properties Disclose Ingredients Health Hazard Information Precautions for Safe Use and HandlingElements of effective OHS Management Systems: Elements of effective OHS Management Systems top level management involvement and commitment line managers and supervisors assigned responsibilities and held accountable written statements of policies and procedures effective employee consultation hazard identification, risk assessment and control induction and training of management and employeesApplication - Hazardous Substances Risk Assessment: Application - Hazardous Substances Risk Assessment We are now well informed about the nature of the hazardous substance. The next step is to assess the risk arising from the use of this substance.

Inspect workplace and evaluate exposure : are workers being exposed? how much; how long; how often are they exposed? is it fumes, dusts, mists? what is route of exposure? are there SOPs? efficacy of control measures? Assessment of main plant reactionAssessment Steps: Assessment Steps Step 7 - Assess the health risk the choices are: no significant risk significant risk but well controlled significant risk that needs to be controlled unsure about risk, need more information on the substance, work or degree of exposure A hit and miss approach to assessment is no good.
