SECTION I — LEGISLATION, WHMIS/GHS & HAZARD COMMUNICATION Questions 1 – 10
1. The OHS Act is best defined as:
A. Detailed legal rules adopted by persons given authority by Parliament
B. The basic legal authority adopted and amended by legislation
C. A workplace-specific safety guideline with no legal force
D. An international hazard communication standard
CORRECT ANSWER B — The basic legal authority adopted and amended by legislation
RATIONALE The Occupational Health and Safety Act is the foundational piece of legislation that establishes the legal
framework for workplace health and safety. It is adopted and amended by the legislative body (Parliament or
provincial legislature). Regulations (A) are the detailed rules created under the authority of the Act.
2. Regulations under the OHS framework are best described as:
A. Voluntary guidelines that employers may choose to follow
B. Detailed legal rules amended and adopted by persons given authority by Parliament
C. Industry best practices with no enforcement mechanism
D. Recommendations from the Canadian Welding Bureau only
CORRECT ANSWER B — Detailed legal rules amended and adopted by persons given authority by Parliament
RATIONALE Regulations are subordinate legislation — they contain the specific, detailed requirements that give effect to
the general principles of the OHS Act. They carry the full force of law and are enforceable. They are created by
persons or bodies to whom Parliament has delegated regulatory authority.
, 3. Developing an effective welding health and safety program is important for all of the following reasons EXCEPT:
A. Prevent and reduce accidents in the workplace
B. Minimize the exposure of workers to hazardous situations and substances
C. Reduce the costs of fatalities and lost-time injuries
D. Maximize production speed regardless of worker safety
CORRECT ANSWER D — Maximize production speed regardless of worker safety
RATIONALE An effective health and safety program prioritizes worker protection — preventing accidents, minimizing
hazardous exposures, and reducing injury costs. Production speed should never come at the expense of
safety. The three legitimate purposes (A, B, C) are all core objectives of a comprehensive safety program.
4. WHMIS stands for:
A. Welding Hazardous Materials Information System
B. Workplace Hazardous Materials Information System
C. Workplace Health and Medical Information Service
D. Welding Health and Materials Inspection Standard
CORRECT ANSWER B — Workplace Hazardous Materials Information System
RATIONALE WHMIS is Canada's national hazard communication system. It ensures that information about hazardous
materials used in the workplace is available to all workers. It covers toxins and chemicals but not physical
agents. WHMIS has been updated to align with the Globally Harmonized System (GHS).
5. The Globally Harmonized System (GHS) is best described as:
A. A Canadian-only hazard identification system
B. An internationally recognized hazard identification and communication system
C. A welding-specific safety certification program
D. A provincial regulatory framework for Ontario only
CORRECT ANSWER B — An internationally recognized hazard identification and communication system
RATIONALE The GHS is a United Nations-developed system that standardizes how chemical hazards are classified and
communicated globally. WHMIS in Canada has been updated to align with GHS standards, ensuring
consistent hazard labels, safety data sheets, and hazard classification across international borders.
6. A supplier label on a controlled product must contain all of the following EXCEPT:
A. Signal word to alert the reader to a potential hazard
B. Hazard statements describing the nature of the hazard
C. Precautionary statements describing measures to minimize or prevent effects
D. The product's wholesale cost and supplier profit margin
CORRECT ANSWER D — The product's wholesale cost and supplier profit margin
RATIONALE GHS-compliant supplier labels require: a signal word (Danger/Warning), hazard statements (describing the
hazard), precautionary statements (how to minimize risk), product identifier, supplier information, and
pictograms. Cost and profit information is not a safety labeling requirement.
