Confined spaces can appear harmless, yet they often contain hidden hazards such as toxic gases, oxygen-deficient atmospheres, or explosive conditions. Each year, workers are injured or killed after entering confined spaces without proper training. An average of 20 people lose their lives annually to confined space incidents, and over half of those fatalities involve untrained individuals attempting rescue.

This Confined Space Hazards Canada course helps workers recognize confined spaces, understand the risks they pose, and follow the procedures their employer has in place to keep everyone safe. Learners explore the conditions that make confined spaces dangerous, how hazardous atmospheres develop, and what responsibilities employers and workers share when planning or performing confined space work.

The course also explains the roles of entrants, attendants, and entry supervisors, and clarifies when a confined space requires a permit. By the end, participants will understand how to identify hazardous conditions, use protective measures, and avoid unsafe rescue attempts that could place additional lives at risk.

Confined spaces are common across construction and industrial workplaces, and understanding their hazards is essential for preventing serious incidents. Whether a worker is entering a tank, pit, vault, bin, crawl space, or similar structure, they must know how to recognize dangerous conditions, test the atmosphere, and follow required entry procedures. This course gives learners the foundational knowledge needed to navigate confined space hazards safely and confidently.
