WHMIS TEST BANK QUESTIONS WITH
VERIFIED ANSWERS FULL REVIEW
●● WHMIS is meant to
Answer: reduce risk, illness, or injury in the workplace due to hazardous
materials when using, storing, or handling them
three components: education and training, proper labeling, and providing
up to date safety data sheets (SDS)
●● GHS
Answer: Globally Harmonized System of Classification and Labeling of
Chemicals-- developed by the UN to classify hazardous materials using
consistent and standardized labeling of chemicals
●● Physical Hazards
Answer: This classification includes materials with physical or chemical
properties that could cause physical harm or destruction. Some examples
include materials that are corrosive, flammable, oxidizing or reactive in
nature.
12 classes
●● Health Hazards
,Answer: This classification includes materials that cause negative effects
on human health. Some examples include materials that cause allergies,
asthma, carcinogenicity (i.e. cancer causing), eye and skin irritation and
mutagenicity (i.e. non-cancerous cell mutations).
12 classes
●● Environmental Hazards
Answer: not focused here, but about the harm it may cause the
environment such as the ozone layer or aquaculture
●● Hazard Classes
Answer: These are more specific and are very important when
considering the classification of a hazardous material
●● Hazard Categories
Answer: Indicates how hazardous a material is. The lower the category
number, the more hazardous a product is. On occasion, categories are
subdivided further using letters of the alphabets. In these situations,
letters earlier in the alphabet are more hazardous than those later in the
alphabet.
2 more hazardous than 3, 1a more hazardous that 1b.
●● Flammables
, Answer: Physical Hazard
This class includes flammable gases, liquids, solids and aerosols. These
materials can ignite easily or explode.
Categories 1-3
Pictogram: Red diamond with a fire inside
●● Oxidizers
Answer: Physical Hazard
This class includes oxidizing gases, liquids and solids. These materials
undergo a chemical reaction where one or more electron is removed
from another chemical. As a result, these reactions may cause or
intensify a fire, or cause an explosion.
Categories 1-3
