Safety Symbols
1
Have you ever seen one of these symbols?
2
Canada uses two standard sets of symbols to identify hazardous materials.
The Hazardous Household Product Symbols (HHPS) • developed for common products used around the home. • the shape and picture shows what and the degree of danger.
The Workplace Hazardous Materials Information System (WHMIS) • developed for products found in work places or science laboratories. • Many workers must undergo WHMIS training every year.
• Includes symbols, labels and MSDS sheets (Material Safety Data Sheet)
Both sets of symbols provide warnings about the hazards of using such products, and precautions to take while using such products.

Did you know that the warning symbols are based on
shape? The more corners a symbol has, the greater
the risk. Read the label to find out how to use the
product safely and what precautions to take.

Compressed Gas
Any material that is normally a gas, but has been chilled and put under pressure inside a container, is a compressed gas.
Warning!
­ if you break the container it will rocket across the room
­ if you heat it, it may explode
­ if it leaks you could get frostbite
Precautions:
­ store in a safe location
­ tie it down during transport
­ handle with care
9
Flammable and Combustible Material
Flammable ­ catches on fire easily at room temperature
Combustible ­ catch on fire if heated
Precautions:
­ Keep away from open flames
­ don’t heat it (room temperature only)
10
Oxidizer
Any material that can cause other materials to burn by supplying oxygen. No spark will be necessary.
Precautions:
­ store in a location away from flammable and combustible materials.
11
Poisonous and Infectious Materials
Division 1: Poison
Immediate serious health risks (coma, death).
Precautions:
­ label containers
­ don’t eat or drink anything
­ use gloves
­ dispose safely
12
Poisonous and Infectious Materials
Division 2: Toxin
Materials that do not have immediate effects, however, may still have very serious consequences.
For example: cancer, reproductive problems (harm to the baby), changes to your genes, or irritation.
Precautions:
­ label containers
­ don’t eat or drink anything
­ use gloves
­ dispose safely
13
Poisonous and Infectious Materials
Division 3: Biohazard
Materials that cause diseases in people or animals. Examples: bacteria, viruses, fungi and parasites.
Precautions:
­ label containers
­ don’t eat or drink anything
­ use gloves
­ dispose safely
14
Corrosive
Warning
Can cause permanent burns to skin, eyes, etc.
Precautions:
­ Handle with gloves
­ Don’t place on high shelves
­ Put cover back immediately
­ Rinse out used bottles
15
Dangerously Reactive
Very unstable!
1) React quickly with water to make a toxic gas.
2) React with itself when bumped or dropped.
3) React with itself (join together or break down).
Precautions:
­ Handle with care
­ Don’t change temperature
