1. WHMIS

2. Class A COMPRESSED GAS  Gases under high pressure  Could explode if dropped, bumped, punctured or heated  Examples: Oxygen, helium, carbon dioxide

3. Class B Flammable and Combustible Material  Flammable ignite & burn at low temperatures.  Combustible are capable of catching fire in the presence of a spark or open flame under normal working conditions.  Propane, gasoline

4. Class C Oxidizing Material  These materials increase the risk of fire if they come in contact with flammable or combustible materials.  Will feed a fire  Examples: Hydrogen Peroxide, nitrogen dioxide, chlorine

5. Class D-1 Poisonous and Infectious Material: Immediate and Serious Toxic Effects  These materials can cause death or immediate injury when a person is exposed to even small amounts & a single time.  Examples: Carbon Monoxide, Cyanide

6. Class D-2 Poisonous and Infectious Materials: Other Toxic Materials  These materials can cause life- threatening and serious long- term health problems as well as less severe but immediate reactions in a person who is repeatedly exposed to small amounts.  Examples: Lead, Nicotine, Agent Orange, Asbestos

7. Class D-3 Poisonous and Infectious Material: Biohazardous Infectious Materials  These materials contain an organism that has been shown to cause disease or to be a probable cause of disease in persons or animals.  Examples: Used Needles, any materials that have come in contact with fluids of living organisms

8. Class E Corrosive Materials  Materials that can destroy the skin and flesh and/or eat through metals  Examples: Hydrochloric Acid, sodium hydroxide, nitric acid, any strong acid or base

9. Class F Dangerously Reactive Materials  These products may self-react dangerously, i.e. may explode, upon standing or when exposed to physical shock or increased pressure or temperature, or they emit toxic gases when exposed to water.  Examples: Sodium, potassium

10. Four Types of Fire Extinguishers: 1.Water 2.Dry Chemical 3.Carbon Dioxide 4.Sand or Salt

11. Five Classes of Fires Class A: Ordinary Combustibles  Use: Water or Dry Chemical  Examples: Wood, paper, organic material anything that produces ash

12. Class B: Flammable Liquids  Use: Carbon Dioxide, Dry Chemical  Examples: Gasoline, lighter fluid

13. Class C: Electrical Fires  Use: Carbon Dioxide, Dry Chemical  Examples: Computers, Electrical Appliances, Wiring in houses

14. Class D: Burning Metals  Use: Sand or Salt  Examples: Sodium, Potassium, Magnesium

15. Class E: Radioactive Fires  Use: No Extinguisher works  Examples: Uranium, Plutonium  Need to do what?
