Q1: What does the acronym WHMIS stand for?
A. Workplace Hazardous Materials Inspection System
B. Worker Health Management Information Standard
C. Workplace Hazardous Materials Information System [CORRECT]
D. Workplace Hazard Management and Inspection Service
Correct Answer: C
Rationale: WHMIS is the Workplace Hazardous Materials Information System, Canada's
national hazard communication standard. The other options use incorrect wording that does
not match the official name or purpose of ensuring workers' right to know about hazardous
products.
Q2: What is the primary purpose of WHMIS?
A. To regulate the transport of dangerous goods across Canada
B. To ensure workers have the right to know about hazardous products in their workplace
[CORRECT]
C. To set maximum exposure limits for all chemicals
D. To replace all provincial occupational health and safety laws
Correct Answer: B
Rationale: WHMIS exists to give workers the right to know about hazardous products through
labels, safety data sheets, and education/training. It does not regulate transport (covered by
TDG) or replace provincial OHS legislation.
Q3: Which federal legislation places duties on suppliers regarding hazardous products under
WHMIS 2015?
A. Occupational Health and Safety Act
B. Hazardous Products Act [CORRECT]
C. Controlled Products Regulation only
,D. Canada Labour Code exclusively
Correct Answer: B
Rationale: The Hazardous Products Act places duties on suppliers (manufacturers, importers,
distributors). Provincial or territorial occupational health and safety legislation places duties
on employers. The Controlled Products Regulation was replaced under WHMIS 2015.
Q4: True or False: The transition to WHMIS 2015 was fully completed across Canada by
December 1, 2018.
Correct Answer: True
Rationale: The phased transition from WHMIS 1988 to WHMIS 2015 ended on December 1,
2018. After that date, all suppliers and employers were required to be fully compliant with
WHMIS 2015 requirements for classification, labels, and safety data sheets.
Q5: Which of the following was a major change introduced by WHMIS 2015 compared to
WHMIS 1988?
A. Elimination of all pictograms
B. Replacement of the hatched border symbols with red diamond-bordered pictograms and
adoption of a standardized 16-section SDS format [CORRECT]
C. Requirement that all SDSs expire every three years
D. Removal of worker education and training requirements
Correct Answer: B
Rationale: WHMIS 2015 aligned with GHS, introducing new hazard classes, red-diamond
pictograms (replacing the old hatched-border symbols), new label formats, and a
standardized 16-section SDS (formerly MSDS). SDSs no longer have a fixed three-year expiry,
and education/training remains a core requirement.
Q6: Under WHMIS 2015, what term replaced “Controlled Products”?
A. Dangerous Goods
B. Hazardous Products [CORRECT]
C. Regulated Substances
D. Workplace Chemicals
Correct Answer: B
, Rationale: WHMIS 2015 changed the terminology from “Controlled Products” to “Hazardous
Products” to align with GHS language. Dangerous goods refer primarily to transport
regulations.
Q7: What are the three key components of WHMIS?
A. Labels, Safety Data Sheets, and Worker Education/Training [CORRECT]
B. Labels, Transport Documents, and PPE
C. SDSs, Fire Codes, and First-Aid Kits
D. Pictograms, Signal Words, and Hazard Statements only
Correct Answer: A
Rationale: The three pillars of WHMIS are supplier/workplace labels, safety data sheets, and
worker education and training. The other options mix elements from different regulatory
systems or list only label components.
Q8: Which level of government is primarily responsible for enforcing employer duties under
WHMIS (such as providing training and workplace labels)?
A. Federal government only
B. Provincial and territorial governments through occupational health and safety legislation
[CORRECT]
C. Municipal bylaws exclusively
D. International GHS secretariat
Correct Answer: B
Rationale: While the federal Hazardous Products Act governs suppliers, provincial and
territorial OHS legislation places duties on employers regarding workplace labels, SDSs, and
worker training.
Q9: True or False: WHMIS 2015 requires suppliers to update safety data sheets every three
years regardless of whether new information is available.
Correct Answer: False
Rationale: Unlike the former system, WHMIS 2015 does not impose a fixed three-year update
cycle. Suppliers must update an SDS when significant new hazard information becomes
available.
