Which source is commonly referenced for ventilation recommendations to reduce welder exposure to welding fume?

• A. The Occupational Health and Safety Act
• B. CSA Standard W117.2
• C. Company health and safety policies
• D. ISO 45001

Answer: (B)

Ventilation control for welding fumes relies on technical guidance that translates exposure limits into practical design and operating requirements. This standard is the one that specifically covers safety in welding, cutting, and allied processes and includes explicit provisions on ventilation design—when to use local exhaust ventilation, how to place hoods, and the airflow levels needed to capture or dilute fumes. Because it directly addresses welding environments, it’s widely used as the reference in safety programs, engineering controls, and inspection checklists to reduce welder exposure. The Occupational Health and Safety Act provides the legal framework, but not the detailed technical ventilation specs. Company policies are internal and can vary, and ISO 45001 focuses on management system structure for OH&S rather than giving the welding-specific ventilation guidance.
