Hazardous Household Waste Household hazardous waste (hhw) is any substance that may be harmful to you, animals, or the environment when not properly handled. Hhw can be in the form of solids, liquids, or gases. Misuse of hhw can lead to pollution of groundwater, lakes, rivers, and soil. An easy way to identify hhw is to look at the label and read disposal instructions.

Workplace Hazardous Materials Information System WHMIS Workplace Hazardous Materials Information System

WHMIS is an information based system. Implemented by the Canadian government in 1988. Educates people on identifying, handling and storage of hazardous materials in the workplace and at school. In 1986, the costs of accidents and ill health to Canadian workers was in the range of $600 million. Exposure to hazardous materials may result in various health effects including burns, rashes, cancer and kidney and lung damage. Improper handling and storage of certain materials could cause an explosion or a fire. There are 6 classes of hazardous materials.

WHMIS Training

Class A: Compressed Gas This class includes compressed gases, dissolved gases and gases liquefied by compression or refrigeration. Examples: helium tank, oxygen tank, fire extinguisher, hairspray, gas cylinders for oxyacetylene welding or water disinfection.

Class B: Flammable and Combustible Material Solids, liquids and gases capable of catching fire or exploding in the presence of a source of ignition. Examples: methane, propane, butane, gasoline, turpentine, ethanol, white phosphorus, and acetone.

Class C: Oxidizing Material Materials which provide oxygen or similar substances and which increase the risk of fire if they come into contact with flammable or combustible materials. Examples: sodium hypochlorite, perchloric acid, inorganic peroxides, sulfuric acid, hydrogen peroxide, fertilizer.

Class D: Poisonous & Infectious Materials - Division 1 Materials causing immediate and serious toxic effects. This division covers materials which can cause the death of a person exposed to small amounts. Examples: sodium cyanide, hydrogen sulphide, carbon monoxide, formaldehyde.

Class D: Poisonous & Infectious Materials - Division 2 Materials causing other toxic effects. This division covers materials which cause immediate eye or skin irritation and or those which can cause long-term effects with repeated exposure to small amounts. Examples: acetone (irritant), asbestos (carcinogen), toluene. Lead, mercury.

Class D: Poisonous & Infectious Materials - Division 3 Biohazardous infectious material. This division applies to materials which contain harmful microorganisms. Examples: cultures or diagnostic specimens containing salmonella bacteria or the hepatitis B virus, blood, anthrax.

Class E: Corrosive Material Acidic or Basic materials which can destroy the skin or eat through metals. Examples: Sodium hydroxide, battery acid, photographic chemicals, some household cleaners.

Class F: Dangerously Reactive Material Products which can undergo dangerous reaction if subjected to heat, pressure, shock or allowed to contact water. Examples: plastic monomers such as butadiene and some cyanides, sodium metal, nitroglycerine.

Lab Safety Always be safety conscious. Move around the laboratory in a safe and slow manner. Never perform unauthorized experiments. Follow all instructions, verbal and written. Plan ahead. Become familiar with all the heath and safety hazards of the equipment and chemicals to be used. If you are not comfortable, inform the teacher.

Know the location of the safety equipment and fire exits Know the location of the safety equipment and fire exits. Use this equipment only in emergencies. Report all accidents – no accident is too small to report Do not attempt to clean up a spill until checking with the teacher. Broken glassware must be dealt with immediately. Inform teacher of all broken glassware.

Safety glasses must be worn while working with any chemical Safety glasses must be worn while working with any chemical. It is recommended that you do not wear contact lenses during labs where chemicals will be used. If you get chemical in your eye, do not wait for the teacher, have a peer take you straight to the eyewash station and flush eyes for 5 minutes.

If you get chemical splashed or spilled on your skin, flush it with water at one of the sinks around the room. If irritation or pain develops, see a physician. Wash hands thoroughly before leaving the laboratory. If you get chemicals on your clothes, wash the clothes, but not with good clothing. You should not wear loose clothing in the lab, nor should you wear good clothing.

Handle all chemicals as if they were dangerous. Tie back long hair. Do not consume food or drink while in the lab. Never taste the chemicals. Keep workstations clear of all books, bags, and clothing. Workstations should have only the materials needed for the lab. Do not sit on the workstation counter.

Clean all equipment thoroughly and put it back where you found it. Follow all directions regarding the disposal of chemicals and solutions. Not everything goes down the sink. Do not put used chemicals or solutions back into the original container. Clean your lab station before leaving the classroom.
