Confined Space Awareness Course 2026

This course is for workers in Canada, including security guards and site staff, who work near tanks, pits, vaults, sewers and similar spaces. It explains what a confined space is, its hazards, air testing, entry permits, attendants and rescue. It is awareness only: it does not train you to enter a confined space, act as an attendant or take part in a rescue, which require training from your employer.

Najczęściej zadawane pytania

Can I enter a confined space after this course?

No. Only workers trained by their employer and authorized under the site's plan and entry permit may enter. Ontario, for example, requires adequate training for entrants, attendants and rescuers. This course is awareness only.

What should I do if someone collapses inside a confined space?

Do not go in. Raise the alarm, call the trained rescue team and 911 as your site plan says, and keep others out.

Why do so many rescuers die?

People rush in to help without testing the air or wearing supplied air, and are overcome by the same hazard. CCOHS reports more than 60% of confined space deaths are would-be rescuers.
