WHMIS Workplace Hazardous Materials Information System (You must know what WHMIS STANDS FOR)  GHS – Globally Harmonized System First created(you must know in 1992 what United by the GHS stands for) Nations An internationally consistent approach to classifying chemical and hazardous material using labels and data sheets. Provides consistency between countries Allows hazards to be instantly recognizable Provides accurate information WHMIS (you must know this slide) WHMIS is Canada’s national workplace hazard communication standard. In 2015, Canada adopted the GHS for classifying and labelling chemicals (WHMIS 2015) WHMIS 2015 provides information on the safe use of hazardous materials in the workplace. WHMIS stands for: -Workplace Hazardous Materials Information System The Key Elements of WHMIS: 1.Product classification – based on their hazardous properties 2.Labels – give basic information to safely use the product 3.Safety data sheets (SDSs) – give more detailed information about the product than that found on the label 4.Worker education – make sure workers understand the You must know this slide 1. Product Classification: Labelling of containers containing hazardous materials Pictograms are graphic images that immediately show the user of a hazardous product what type of hazard is present. 2. Labels: You must know this slide: Types of Labels on Chemicals: a. Supplier labels Must be in English and French b. Workplace labels The labelling of materials that have been removed from their supplier container, have lost their label or were created in the workplace Both types of labels may contain Supplier Label Workplace label Safety Data Sheets (SDSs): The SDS summarizes the health and safety information available about a hazardous product. The SDS contains much more information than the label. You must know the yellow Identify the product (Name) Identify physical and health hazards (ex. Fire or cancer causing) Identify safe handling (ex. Wear gloves), storage instructions Identify the appropriate response in case of emergency (exposure or accidental release of a material). 9. Physical and chemical properties The SDS has 16 sections with the following headings and corresponding 10. Stability and reactivity numbers. 11. Toxicological information 1. Identification 12. Ecological information 2. Hazard identification 13. Disposal considerations 3. Composition/Information on ingredients 14. Transport information 4. First aid measures 15. Regulatory information 5. Fire-fighting measures 16. Other information 6. Accidental release measures 7. Handling and storage 8. Exposure controls/Personal protection 4. Worker Education and training You!!! (Science, Technology, Arts) Most jobs require WHMIS WHMIS Symbols Revisited: WHMIS groups chemicals with similar properties or hazards into 12 categories of health hazards and 9 categories of physical hazards. Two environmental hazard classes have not been adopted by Canada but may be seen on SDS arriving from other countries. Symbols are used to help people recognize the hazard quickly. You must know this: The WHMIS Symbols are pictograms in a red square tilted 45⁰ on a point. 16 Hazard Classes  You must know everything highlighted in yellow for the rest of the slides plus the  Gas Cylinder - For gases under pressure s Under Pressure – may explode if heated rigerated liquified gases may cause severe cryogenic (cold) Oxygen tank, propane tank, fire extinguisher  Flame - For fire hazards - Materials that can catch fire easily, are self heating or react with water. - Ex. Gasoline, spray paint, alcohol Flammable – ability to ignite (catch fire) easily Self-Reactive – react on their own to cause fire or react when heated Pyrophoric – catch fire quickly if exposed to air Self-Heating – catch fire if exposed to air over a longer period of time or in large amounts In Contact with Water, Emits Flammable Gases Organic Peroxide – unstable products that may cause fire if heated  Flame over circle - For oxidizing hazards Oxidizers – May intensify a fire or cause a fire or explosion (produce oxygen) (The ‘O’ stands for oxygen!) Ex. Oxygen, chlorine bleach, hydrogen peroxide, Potassium Chlorate (KClO 3)  Exploding Bomb - For explosion or reactivity hazards - Materials that could react on their own or cause a fire or explosion Ex. Aerosol cans, nitroglycerin Explosive (not required but may be used) Self-Reactive (severe) - react on their own to cause fire or react when heated Organic Peroxide (severe) - unstable products that may cause fire if heated  Skull and Crossbones - Harmful or fatal. Can cause death or toxicity with short exposure to small (inhaled, skin contact, swallowed) to small amounts or short periods of time Ex. Carbon monoxide, arsenic Acute Toxicity (fatal or toxic) - harmful if breathed in, injected or contacted by skin  Health Hazard - May cause or suspected of causing serious health effects. May cause long term health problems especially with repeated exposure (respiratory problems, skin reactions, damage to internal organs, carcinogenic (cancer causing) Ex. paints, radiation, asbestos, mercury, lead Carcinogenicity – cancer causing Respiratory Sensitization – allergy, asthma or breathing difficulties Reproductive Toxicity – may damage fertility, embryo, fetus or offspring Specific Target Organ Toxicity - eg. may damage liver, blood or kidney after a single exposure Germ Cell Mutagenicity – causes genetic defects that can be passed on to future generations Aspiration Hazard – may be fatal if swallowed and enter airways  Corrosion - For corrosive damage to metals as well as to skin and eyes Ex. Hydrochloric acid, sulfuric acid Serious Eye Damage Skin Corrosion - burns Corrosive to Metals  Explanation Mark - May cause less serious health effects(irritant to skin or eyes, difficulty with respiration) - Also used for damage to the ozone layer (not adopted in Canada) Ex. Sulfuric acid (car battery), cleaners and detergents, coolant fluid Irritation (of skin or eyes) Skin Sensitization – allergic skin reaction Acute Toxicity - harmful if breathed in, injected or contacted by skin Specific Target Organ Toxicity – eg. May damage liver, blood or kidney after a single exposure May cause drowsiness or dizziness, or respiratory irritation  Biohazardous Infectious Material - For organisms or toxins that cause diseases or infections in people or These materials animals are microorganisms (eg. Bacteria, viruses, fungi), nucleic acids or proteins that causes cause disease or illness in humans or animals. Ex. Infected Blood and blood products, human and animal waste, bacteria, viruses. Environment - May cause damage to the aquatic environment - This is an optional category in Canada but is widely used in other countries. Ex: Drano, Bleach What Label would you use? What Label would you use? What Label would you use? What Label would you use? Hazardous Household Product Symbols (HHPS) Safety symbols found on common products in our home. 1. Picture – tells you the type of danger 2. Frame - The shape of the frame around the hazard symbol tells you what part of the product is dangerous. Triangle – BE CAUTIOUS AROUND THIS AND USING THIS Square on Point- Be Extra Cautious, likely risks Octagon – DANGEROUS 3. Signal words – tell you the degree of risk (caution, danger, Warning) 4. Sometimes the Frame has a colour associated with it (Danger Red, Warning Orange, or Triangle Yellow Caution) What Label would you use?
