WHMIS Flashcards
What does WHMIS stand for?
workplace hazardous materials information system
____ health effects happen quickly, usually a short time after exposure
acute
_____ health effects happen slowly over time
chronic
WHMIS legislation defines that there are typically three primary parties
which are required to adhere to particular duties and responsibilities
pertaining to WHMIS.
What are the 3 parties?
1) Supplier
2) Employer
3) Workers
What are supplier duties?
provide labels and safety data sheets for all hazardous products that they import or manufacture
What are employer duties?
- make sure that safety data sheets are easy for workers to find and read
- make sure that containers in the workplace are labelled
- provide WHMIS training to employees/workers
What are worker duties?
- participate in training
- use their knowledge of WHMIS to work as safely as possible
Do workers have the right to refuse work that they believe is dangerous?
yes
What are 4 primary routes of entry for chemicals to enter the body?
1) Inhalation
2) Ingestion
3) Absorption
4) Injection
Select which route of entry matches the following statement:
_____ may be the most common way in which hazardous materials
can enter your body.
Dust, mist, fumes and vapors can be inhaled through your nose or mouth
and travel into your lungs, where they can begin to cause damage and
even enter into your blood stream.
Inhalation
Select which route of entry matches the following statement:
Some hazardous materials can also enter your body by passing through
your skin.
The severity of the harm also varies drastically depending on what type of
chemical has come into contact with you.
Some hazardous materials will cause your skin to become very sensitive,
while others may pass directly through the skin and into the blood
stream.
Absorption
Select which route of entry matches the following statement:
Chemicals can easily be absorbed through your digestive system.
This can occur if you have hazardous materials on your hands while
eating or smoking.
It’s also possible to swallow chemicals if food is left uncovered in areas
where there is a risk of exposure to the chemicals.
Ingestion
Select which route of entry matches the following statement:
Chemicals can enter the body and particularly the bloodstream through
lacerations, punctures, or syringe needles.
Injection
List 3 types of hazard groups
physical hazards
health hazards
environmental hazards
_____ hazards are classified according to their physical or chemical properties such as reactivity, flammability, compressed gases or corrosiveness
physical
_____ hazards are classified in this group based on their ability to cause adverse health effects such as toxicity, respiratory sensitization, eye irritation or carcinogenicity
health
_____ hazards exists in the GHS (global harmonized system) but has not been adopted into WHMIS 2015
environmental
MSDS stands for?
material safety data sheet
______ = the product can burn your skin or eyes. If swallowed it will damage your throat and stomach
corrosive
_______ = the product or it’s fumes will catch fire easily if near heat, flames or sparks. Rags used with this product may begin to burn on their own
flammable
_______=the container can explode if heated or punctured. flying pieces of metal or plastic from the container can cause serious injury, especially to eyes.
explosive
______=if you swallow, lick or in some cases, breathe in the chemical, you could become very sick or die
poison
Octagon frame means what?
the contents inside are dangerous
Triangle frame means what?

- WHMIS has aligned with the worldwide hazard communication
system known as GHS – the Globally Harmonized System of
Classification and Labeling of Chemicals.
True or False
True
- The Globally Harmonized System (GHS) is an internationally
consistent approach to classifying chemicals and communicating
hazard information through labels and Safety Data Sheets?
True or False
True
- GHS is based on the same 4 building blocks of WHMIS and will
provide improved protection for workers when handling hazardous
material?
True or False
True
- Material Safety Data Sheet Requirements (MSDS) require 4 pieces of
information whereas Safety Data Sheets (SDS) have 14 requirements?
True or False
False

- A simple asphyxiate hazard is defined as?
a. A finely divided solid material that can catch fire or explode
b. A substance or mixture that displaces oxygen in the
atmosphere
c) A gas that spontaneously ignites in the air
