SNC2P Safety Symbols

Science Science is a way of gaining knowledge and understanding of our world. It is the desire to understand how and why things work. Science, in its purest form, is done out of simple curiosity. It is concerned with knowledge and ideas.

Technology Technology is applying knowledge to make products that will improve the quality of our lives. It answers human needs. Technology is concerned with the production of things.

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.

Hazardous Household Product Symbols

Containers labeled with this symbol are explosive. They may produce deadly fumes or vapors when exposed to air Keep away from heat.

Any product with this symbol is flammable. Keep away from sources of spark or flame.

Hazardous Household Product Symbols Products with this symbol are poisonous or lethal if swallowed, inhaled, or absorbed

A product with this symbol is corrosive and can cause burns to your skin and eyes and can eat away at other material.

Degree of Danger The degree of danger of hazardous household products is indicated by the shape outlining the symbol. Danger – Warning – Caution –

Workplace Hazardous Materials Information System

WHMIS Workplace Hazardous Materials Information System was implemented in 1988 as a national system to provide information on hazardous materials used in the workplace. The key elements of the system are the material safety data sheets (msds), the simple labeling system, and the workers education program.

The WHMIS Board contains all the symbols with explanations. There is also a binder with the data sheets for each chemical in the facility.

This is a container of toluene. You can see the WHMIS label clearly by the dashed border and the hazard symbols.

WHMIS Symbols Compressed Gas – materials that are normally gaseous and kept under pressure. These may explode if dropped or exposed to pressure or heat. Flammables and Combustibles – materials which ignite easily and will continue to burn after being exposed to flame or spark.

WHMIS Symbols Continued Oxidizing Material – materials which can cause other materials to burn. Will cause combustibles to react violently Can cause skin and eyes to burn. Toxic, immediate and severe effects – poisonous and potentially fatal materials that will cause severe harm if inhaled, ingested, or absorbed (even in small amounts).

WHMIS Symbols Continued Toxic, long term effects – materials which may have harmful effects after repeated exposure. May cause death or permanent injury, birth defects, sterility, cancer, or even allergies. Biohazardous infectious – Infectious agents or biological toxins causing serious disease or death. Includes viruses, yeasts, molds, bacteria, parasites.

WHMIS Symbols Continued Corrosive Materials – materials that react and cause skin irritation, severe burns and tissue damage, lung damage, eye irritation or blindness, as well as environmental damage from fumes. Dangerously reactive material – these have unexpected reactions. They may react with water. They may be unstable in air. They may explode if exposed to shock or heat. May release toxic fumes or burn unexpectedly.
