Occupational Health and Safety, Legislation, and Regulatory Compliance
What this domain tests
This domain checks whether you can locate and apply the OHS duties, crane-specific rules, and certification requirements that govern mobile crane work in Canada. Most occupational health and safety law is provincial or territorial; federal rules apply in federally regulated workplaces. The Red Seal exam expects you to know the internal responsibility system, the three worker rights, and the role of a competent person.
Core rules and concepts
- Employer: provide safe equipment, training, supervision, and maintain records.
- Supervisor: ensure work is done safely, correct unsafe acts, and know the hazards.
- Worker: follow procedures, use PPE, report defects, and refuse work you reasonably believe is unsafe.
- "Competent" means trained, experienced, and qualified to perform the task; "certified" means holding the required provincial credential.
- CSA Z150 is a common technical standard for mobile cranes, but it is not itself a statute; regulations may adopt it by reference.
- Power-line approach limits, annual inspection, load charts, log books, and signal-person requirements are typically set by provincial crane regulations.
- Report incidents, near misses, and equipment defects as required; never alter a scene except to rescue or prevent further harm.
Worked example
A crew asks you to set an outrigger pad beside an unprotected trench because the lift is quick. The soil is disturbed and the pad would sit within the trench's zone of influence. You stop and request a competent ground assessment and repositioning. Reason: the employer must provide a safe work area, and the operator must not set up where stability is compromised. "Quick" does not override the hazard.
Traps that cost marks
- Assuming one national OHS law applies everywhere.
- Treating CSA Z150 as law without checking the local regulation.
- Confusing "competent" with "certified."
- Believing a supervisor's instruction removes your right to refuse unsafe work.
- Forgetting documentation duties after an incident.
