1 Date: Lab Safety WHMIS stands for: W: H: M: I: S: A Canada-wide system designed to give & information about hazardous materials used in the workplace WHMIS deals with Any substance or material which meets any of the criteria for inclusion in one of the WHMIS Hazard Classes Was created in response to the Canadian workers' right to know about the and that may be associated with the materials or chemicals they use at work Was created to help stop the, illnesses,,, and fires caused by hazardous materials This applies to all of Canada Became law effective October 31, 1988 Updated in 2015 Page 1 of 11

2 Employer Duties Employers are required to establish for workers exposed to in the workplace Employers must also make sure that the products are and that an is present for each product and that they are readily available to workers Worker Duties Workers are required to in the training programs and to use this information to help them work safely with hazardous materials They may also when on containers have been accidentally or no longer Main Components of WHMIS WHMIS Hazard Classes Page 2 of 11

3 WHMIS does not apply to: Nuclear Safety & Control Act Explosives Act Food & Drugs Act Flame Classifying material that will and continue to in air if exposed to a source of ignition This class includes gases, aerosols, liquids and solids Includes materials Flammable: Flashpoint is Combustible: Flashpoint is between and Flashpoint: the lowest temperature at which a liquid produces enough vapour to Fire hazard will burn if ignited Could ignite spontaneously Could ignite upon mixing with or other chemicals Avoid contact with flames, heat, & ignition sources Cap tightly for storage, are flammable Store in flammable Store separate from Page 3 of 11

4 Flame over Circle This symbol identifies material that or other substances and thereby contributing to the combustion of other flammable materials May cause combustibles to explode or react Many are & Store away from sources of Store separately from Store in non-corroding containers Gas Cylinder Classifying material which is a gas at normal and, packaged under pressure in a cylinder or other container Many of our laboratories and work areas use cylinders of various sizes and contents hazard cylinder to the wall standing upright with when not in use Avoid sources Transport using specialized cart Store in cool ventilated area Page 4 of 11

5 Corrosion Corrosive material can attack and other substances and can cause permanent damage to and Fumes from these materials can also damage our Will burn human including skin, eyes, nose, mouth, throat & lungs Will many materials particularly metals Wear appropriate (gloves, goggles) Work in a well When diluting acids, always add to Store in non-corroding containers, on non-corroding trays Exploding Bomb This symbol identifies dangerously explosive or reactive materials These materials may react under certain conditions Few of our work areas use or store these materials May be unstable or vigorously May when shocked or heated Highly reactive with incompatible materials Wear appropriate (gloves, goggles) Store away from Keep away from Page 5 of 11

6 Skull and Crossbones The skull and cross bones identify acutely toxic material These materials can our health in a Small quantities may be May be toxic not only if but also if or through skin Wear appropriate (gloves, goggles) Do not or inhale, avoid skin contact Avoid creating Handle the exterior of containers as though it is Health Hazard This symbol is used to identify health hazards Hazards include allergic reactions,,, Also can damage organs like, Materials which have harmful effects after exposures Can also be an risk Wear appropriate (gloves, goggles) Do not or inhale, avoid skin contact Avoid creating Handle the exterior of containers as though it is Page 6 of 11

7 Exclamation Mark This symbol is used to identify health hazards Hazards cover a wide range of dangers Wear appropriate (gloves, goggles) Do not or inhale, avoid skin contact Avoid creating Handle the exterior of containers as though it is Biohazardous Infectious Material This distinctive symbol identifies material that presents the risk or danger of infection on contact Containers for biomedical waste and used, and are marked with this symbol Infectious materials which may cause or Wear appropriate (gloves, goggles) Do not or inhale, avoid skin contact Be careful of Handle the exterior of containers as though it is Page 7 of 11

8 Label Types Supplier Labels Workplace Labels Are required when: the product is the product is to new container from a stock bottle the supplier label becomes Page 8 of 11

9 Safety Data Sheets (SDS) Summary documents that provide information about the of a product and advice about Provide more detailed hazard information about the product than the How to use the product What to do if occur Section Hazardous Products Regulations Heading 1 Identification 2 Hazard identification (including classification and label text) 3 Composition/information on ingredients 4 First-aid measures 5 Fire-fighting measures 6 Accidental release measures 7 Handling and storage 8 Exposure controls/personal protection 9 Physical and chemical properties 10 Stability and reactivity 11 Toxicological information Ecological, transport and regulatory information, disposal considerations 16 Other information Page 9 of 11

10 Hazardous Waste Disposal Hazardous wastes will be placed in The OCDSB has a contractor pick-up and process hazardous chemicals on a regular basis No hazardous waste goes down the Spill Clean Up Consult teacher for spill cleaned up If a spill occurs that poses an immediate risk to people, or if someone is injured, it is an EMERGENCY call the main office and ask for EMS (emergency medical services) The best time to learn about cleaning up a spill is it happens read the SDS Hazardous Household Products Symbols Were developed for people buying and using materials around the Most household products and pesticides sold in Canada have warning labels Canadian laws for hazardous household chemicals are regulated by Laws for are different Page 10 of 11

11 National Fire Prevention Association Diamond The National Fire Protection Association (NFPA) in the United States uses a standard called NFPA 704 as a chemical hazard label NFPA 704 is called the because the diamond-shaped sign indicates flammability of a substance Also communicates essential information about how emergency response teams Page 11 of 11
