The Workplace Hazardous Materials
Information System (WHMIS) is
Canada's national hazard communication
standard.
The key elements of the system are
cautionary labelling of containers of WHMIS
"controlled products", the provision of
material safety data sheets (MSDSs) and
worker education programs


CLASS A: COMPRESSED GAS
This class includes compressed gases,
dissolved gases, and gases liquefied by
compression or refrigeration.


CLASS B: FLAMMABLE AND COMBUSTIBLE
MATERIAL
This class includes solids, liquids, and gases
capable of catching fire in the presence of a
spark or open flame under normal working
conditions.


CLASS C: OXIDIZING MATERIAL
These materials increase the risk of fire if
they come in contact with flammable or
combustible materials.



CLASS D: POISONOUS AND INFECTIOUS
MATERIAL
Division 1: Materials Causing Immediate and
Serious Toxic Effects
These materials can cause death or
immediate injury when a person is exposed
to small amounts. Examples: sodium cyanide,
hydrogen sulphide


CLASS D: POISONOUS AND INFECTIOUS
MATERIAL
Division 2: Materials Causing Other Toxic
EFFECTS
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.


CLASS D: POISONOUS AND INFECTIOUS
MATERIAL
Division 3: Biohazardous Infectious MATERIAL
These materials contain harmful microorganisms that have been classified into Risk
Groups 2, 3, and 4 as determined by the
World Health Organization (WHO) or the
Medical Research Council of Canada.


CLASS E: CORROSIVE MATERIAL
This class includes caustic and acid materials
that can destroy the skin or eat through
metals. Examples: sodium hydroxide,
hydrochloric acid, nitric acid


CLASS F: DANGEROUSLY REACTIVE MATERIAL
These products may self-react dangerously
(for example, they may explode) upon
standing or when exposed to physical shock
or to increased pressure or temperature, or
they emit toxic gases when exposed to water.
WHMIS labels include first aid information and
details about storage, handling, and disposal.
There are two types of WHMIS labels:
- Supplier labels
- Workplace labels


Supplier labels are used by the people who
make each chemical.
Supplier labels have a strict format.

Hashed marked identifier label
Written in English and French
Supplier Name
Precautionary measures
Risk Phrases
First Aid Treatment
Name of product
Hazard Symbols
Statement referring to MSDS


After chemicals are rebottled, a workplace
label my replace the Supplier label. Workplace
labels are allowed to have different formats.
A Workplace label contains less information
than the Supplier label, but it still has enough
information to help you use the chemical
safely.

WHMIS hazard symbols (optional)


Each chemical found in your home has a
special purpose. The properties of the
chemical determine what it will react with. In
general we do not want products in our
homes to react with each other.
On the other hand there are products that we
do want to react with other materials. These
are normally cleaners that contain materials
such as bleach and ammonia, which are very
reactive chemicals


In order to notify users which chemicals are
dangerous and in what ways they are
dangerous we use Hazardous Household
Product Symbols.
The HHPS has four categories of Hazardous
materials as well as three levels of severity.
The HHPS has four categories of Hazardous
Chemicals
flammable
toxic
corrosive
explosive
The symbols are similar to that of WHMIS with the
exception of the Explosive symbol.


The HHPS has three levels of severity
Caution is the least sever of the three symbols,
warning is more severe and danger is the most
severe.

Household chemicals can be categorized
according to where they are used: kitchen
and bathroom, the garage, the walls, and the
garden.



Many cleaners contain substances that
dissolve or interact with dirt and grease, but
may also contain hazardous chemicals.
There are many environmentally friendly
products that are alternatives to the
hazardous chemicals.
When using chemicals try to avoid using more
than is needed.

Many hazardous solvents are used on
automobiles. Proper handling and disposal is
essential to avoid contamination of soil and
ground water.



Paints and solvents contain hazardous
chemicals.
When painting try to use latex water based
paints that are low in Volatile Organic
Compounds (VOCs)
Recycling unused paint and paint tins




Chemicals used for lawns and gardens include
fertilizers and pesticides.
Fertilizers are fine as long as they are used properly.
Pesticides on the other hand can be incredibly
poisonous. New regulations were passed last year limit
the use of such products to registered users. Fines can
be issued to those using the products without
legitimate registrations.
Alternatives to chemical pesticides
◦ Predator insects
◦ Insect traps
◦ Remove trash and waste from gardens
