Question 1
Which of the following is not a duty of a supervisor?
A. Take every precaution reasonable in the circumstances to protect the workers
B. Provide workers with written instructions for the measures and procedures to be
taken to protect the workers
C. Ensure that workers use or wear the equipment, protective devices or clothing

pg. 1
,Rationale: The preparation and implementation of a written health and safety
program is the responsibility of the employer, not the supervisor. Supervisors are
responsible for ensuring worker safety, providing instructions, and ensuring PPE
compliance, but developing the full health and safety program is an employer-level
duty.
Question 2
To create a safe working environment, the employer must inform workers about
the hazards and provide a safe working environment and the worker must use the
required protective equipment and follow safety procedures.
A. True
B. False
Answer: A
Rationale: This statement is true. Both employers and workers have shared
responsibilities for workplace safety. Employers must provide information and a
safe environment, while workers must use protective equipment and follow safety
procedures. This is a fundamental principle of occupational health and safety
legislation.
Question 3
Which level of government created the Workplace Hazardous Materials
Information System (WHMIS)?
A. Local
B. Federal
C. Provincial/Territorial
D. Municipal
Answer: B
Rationale: WHMIS was created at the federal level and is implemented through
federal legislation (Hazardous Products Act). It establishes national standards for
hazard classification, labeling, and Safety Data Sheets.
pg. 2
,Question 4
What is the name for WHMIS symbols?
A. Danger Symbol
B. Warning Symbol
C. Hazard Symbol
D. Safety Symbol
Answer: C
Rationale: WHMIS symbols are called Hazard Symbols. These pictograms
communicate specific hazards associated with hazardous products, helping workers
identify risks at a glance.
Question 5
What welding-related materials may be covered under WHMIS? (Select all that
apply)
A. Gases for cutting and welding
B. Radiography sources
C. Materials to be welded
D. Welding consumables
Answer: A, C, D
Rationale: WHMIS covers hazardous materials used in the workplace, including:
welding gases (compressed gases), materials to be welded (which may contain
hazardous substances), and welding consumables (electrodes, fluxes). Radiography
sources are covered under other safety regulations (radiation protection), not
WHMIS.
Question 6
What are the three methods used to provide WHMIS information?
A. Product labels, workplace labels and training
B. Product labels, material safety data sheets and training
C. Product labels, laboratory labels and workplace labels
D. Workplace labels, training and Safety Data Sheets
pg. 3
, Answer: B
Rationale: The three methods used to provide WHMIS information are: Product
labels (on containers), Safety Data Sheets (SDS) providing detailed hazard
information, and worker training to ensure understanding of hazards and safe
handling practices.
Question 7
How is the following information made accessible to workers: hazardous
ingredients, preparation, product information, physical data, fire or explosion
hazards, reactivity data, toxicological properties, preventive measures and first aid
measures?
A. On workplace labels
B. On material safety data sheets (Safety Data Sheets)
C. On product labels
D. Through training only
Answer: B
Rationale: Safety Data Sheets (SDS) contain all the detailed information listed in
the question. These documents provide comprehensive hazard and safety
information for hazardous products and must be readily accessible to workers.
Question 8
True or False? The first step towards creating a safe workplace is to make certain
that all machine guards are in place.
A. True
B. False
Answer: A
Rationale: The statement is true. Machine guards are essential safety devices that
protect workers from moving parts and other mechanical hazards. Ensuring all
guards are in place is a fundamental step in workplace safety.
