From the study guide
Maintaining a safe work environment is the foundational responsibility of a Red Seal plumber, governed primarily by the Occupational Health and Safety (OHS) regulations and the Workplace Hazardous Materials Information System (WHMIS). A safe site requires proactive hazard identification, including the assessment of confined spaces, trenching stability, and the presence of combustible gases. By adhering to these standards, plumbers prevent workplace injuries, avoid costly project delays, and ensure compliance with provincial and federal labor laws.
