HAZARDS
Chemical and physical health hazards

Chemical and physical hazards are materials that in
the event of exposure may result in serious health
problems, such as:
•
Burns to your skin or eyes (upon contact)
•
Allergic reactions
•
Kidney or lung damage
•
Biological diseases
•
Sterility
•
Cancer
WHMIS Hazard Symbols

There are 6 categories and 8 WHMIS hazard symbols used for
industrial products:
•
Compressed Gas
•
Flammable and Combustible Material
•
Oxidizing Material
•
Poisons and Toxic Materials
‐
Immediately Poisonous Material
‐
Material Causing Other Toxic Effects
‐
Bio-hazardous Infectious Material
•
Corrosive Material
•
Dangerously Reactive Material
Class A: Compressed Gas

Materials under Class A are held under pressure and can
explode if heated or subjected to physical shock.

Handling Tips:
•
The container must be secured and held up-right when
stored or moved.
•
The cap must be kept on when not in use.
•
If the container has a regulator, the regulator must be
disconnected before it is moved.
•
To avoid impact forces the container should never be
dropped, dragged, rolled or punctured.
•
Always keep containers away from heat and sparks.
•
Never use grease/oil on any valve on the container.
Examples
• Oxygen
• Fire Extinguisher
Class B: Flammable and Combustible
Material

Materials under Class B can burn and/or burst into flames very
easily and suddenly when exposed to spark or open flame.

Handling Tips:
•
Always keep containers away from heat and flames.
•
Always keep containers sealed tightly to avoid accidental release
into the environment.
•
Always clean up spills immediately and dispose of clean up
materials in a metal container.
•
Never store near oxidizing or reactive materials.
Examples
• Isopropyl Alcohol
• Formaldehyde
Class C: Oxidizing Material

Materials under Class C increase the risk of a fire and/or
explosion in the presence of flammable or combustible materials.

Handling Tips:
•
Always keep containers away from heat and flames.
•
Always keep containers sealed tightly to avoid accidental release
into the environment.
•

Class E: Corrosive Material

Materials under Class E have the potential to cause severe irritation
and/or tissue damage under the following circumstances: upon
contact with the skin or eyes, when inhaled, when ingested.

Some of the materials under Class E also have the ability to eat
through metal.

Handling Tips:
•
If exposed, immediately flush out the skin or eyes for at least 15
minutes and seek professional medical care if symptoms do not
resolve quickly.
•
Always use in a well ventilated area.

Class F: Dangerously Reactive Material

Materials under Class F are very unstable and have the potential
to self-react dangerously upon standing or if there is a change in
temperature, pressure, physical shock or exposure to air/water.

Handling Tips:
•
Always keep these materials away from any source of heat.
•
Always dispose of old chemicals as soon as possible.
•
Always handle with care, DO NOT DROP.
•
Never mix these materials with other chemicals.
Examples
•
Never mix these materials with water.

Consumer Product Warning Symbols

Consumer Warning Labels are used on products that can be
found on store shelves.

These symbols are similar to the WHMIS industrial symbols with
the exception of the outer boarder.

Each outer border designates the product’s level of danger

MEANS OF
EXPOSURE
Acute vs Chronic Effects


Acute Effect
•
Exposure causes immediate harm to your health (inside
and/or out).
•
The effects of exposure can occur within a few minutes, a
few hours or a few days.
Chronic Effect
•
Exposure causes harm to your health over a longer period
of time.
•
The effects of exposure can occur months or years after
the exposure occurred.
Measuring Acute Toxicity

Lethal Dose 50 (LD50)
•
The amount of material that causes death in 50% of the test
patients when it is introduced into their body by a specified route.
•
Usually method of exposure is ingestion or skin absorption
•
It is usually measured in mg/kg or mL/kg of body weight
•
Higher LD50 = Lower toxicity
•
Lower LD50 = Higher toxicity
Measuring Acute Toxicity

(continued)
Lethal Concentration 50 (LC50)
•
The airborne concentration of the substance that causes death in
50% of the test patients in a given time frame.
•
Usually expose patients for 4 hours.
•
It is usually measured in mg/kg or mL/kg of body weight
•
Higher LC50 = Lower toxicity
•
Lower LC50 = Higher toxicity

Material Safety Data Sheets (MSDS)

A Material Safety Data Sheet is a document that provides
detailed health and safety information specific to the
material.

The content of the MSDS is legislated by WHMIS and
includes 9 sections. Every section must be completed for
every hazardous material. If the information is unavailable
or inapplicable for a particular product, then it must be
stated in the MSDS.

The supplier must update the MSDS every 3 years or within
90 days of a change to the product.

Personal Protective Equipment (PPE)

PPE is necessary when engineering and/or administrative
controls cannot completely remove the hazard to workers.

The purpose of PPE Is to minimize the exposure to
hazardous materials in the workplace.

Employers are responsible for:
•
Supplying appropriate PPE
•
Ensuring PPE is in good working order
•
Providing training to all workers on when and how to use the
PPE

GHS
Globally Harmonized System (GHS)

The Globally Harmonized System of Classification and
Labelling of Chemicals (GHS) is an international initiative to
standardize chemical hazard classification and
communication globally. The GHS is anticipated to be
implemented in Canada in June 2015.

GHS will not replace WHMIS. WHMIS will be modified to
incorporate the GHS elements.
GHS

(continued)
Under GHS, there will be new standardized:
1.
Classification Rules
•
2.
3.
Provides guidance on classifying pure chemicals and mixtures
according to its criteria or rules
Label Requirements
•
Standardized hazard statements
•
Signal words
•
Symbols
•
Precautionary statements may also be required
Safety Data Sheet (SDS) Format
•
This document will replace the Material Safety Data Sheet
(MSDS) that are currently used under WHMIS
•
They will have 16 sections in a set order, and minimum
information prescribed
