Safety-WHMIS Symbols Chart

Symbol	Name	Example	Safety Considerations
	Compressed Gas	Propane	Make sure all the materials are clean and not broken when working with compressed gas. Also make sure the lid is tuck tight when you use the compressed gas. Avoid all direct skin contact with extremely cold liquids or compressed gases escaping from the cylinder. Never wear watches, rings, or bracelets because they can freeze to exposed skin if splashed by an ultra cold gas. Wear insulated gloves to protect against the cold.
	Flammable and Combustible Material	Gasoline	Don’t heat containers or distribution systems containing flammable or combustible liquids. Don’t use flammable or combustible liquids for anything other than their intended uses.
	Oxidizing Material	Nitric Acid	Don’t use corks or rubber stoppers to seal containers. Don’t return any used or unused oxidizers to the original container. Traced amounts of contaminant might start a dangerous reaction. Don’t clump or grind lumps of oxidizers to break them up, as they may be shock sensitive. If crystals have formed in containers, contact your supervisor about safe handling and disposal. Don’t slide on heavy metal drums across floors. Don’t reuse empty containers as they may contain oxidizer residue. Don’t use sawdust or other combustible materials to clean up spills of oxidizing materials.
	Materials Causing Immediate and Serious Toxic Effects	Carbon monoxide	Use only in well-ventilated areas. Wear the appropriate personal protective equipment that your employer specifies for the job. This equipment may include respiratory protection, goggles, face shield, and chemical protective clothing, such as an apron and gloves made from materials that protect against the chemicals being handled. Be aware of the typical symptoms of an overexposure and appropriate first aid procedures. Any signs of illness should be reported immediately to your supervisor. Practice emergency procedures so that you know what to do in case of a spill or other emergency. Report any ventilation failures, leaks or spills to your supervisor immediately. Also have no pregnant women near and trying out any type of these materials.
	Materials Causing Other Toxic Effects	Acetone	Same as Materials Causing Immediate and Serious Toxic Effects.
	Biohazardous Infectious Materials	Hepatitis B	Always wash your hands, do not breath in enemy horrible flumes, wear non-permeable gloves, a face mask and cover any skin so you do not get any skin infected.
	Corrosive Material	Hydrochloric Acid	Use corrosion-resistant equipment such as pumps, scoops or shovels to handle corrosive materials. Flush your contaminated eyes or skin with water for at least 20-30 minutes, sometimes longer, in case of accidental contact. Call immediately for emergency medical assistance. Never handle drums that appear to be swollen. Drums may need to be vented periodically by trained personnel in order to release pressure buildup. The MSDS will indicate if, and how often, this procedure is required. Do not add water to corrosive materials, because this can cause a violent reaction. If it is absolutely necessary to mix a corrosive with water, do so slowly adding the corrosive to cold water, in small amounts, and stir frequently. Do not return unused material to the original container. It may contain traces of contamination and could cause a chemical reaction to occur, possibly leading to container rupture. Do not reuse empty containers.
	Dangerously Reactive Material	Aluminum Chloride	Use the smallest amounts possible. Eliminate ignition sources (sparks, open flames). Keep containers away from heat and out of direct sunlight. Avoid sudden temperature changes. Keep away from all incompatible materials. Consult the MSDS for specific details. Store container according to manufacturer’s recommendations, including temperature range. Store in the shipping container or other approved, labeled container. Label containers with date opened and disposal date. Avoid prolonged storage. Inspect containers regularly for signs of bulging, corrosion, colour change, etc. Check stabilizer/inhibitor levels regularly and replenish as necessary or as specified by the manufacturer. Do not use material if physical characteristics and appearance do not match the MSDS or if material is of unknown age. Do not return any used or unused material to the original container. Trace amounts of a contaminant might start a dangerous reaction. Do not reuse empty containers as they may contain hazardous residue.
