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.

  1. Fråga 1 av 25

    Which of these is part of the general definition of a confined space?
    Visa svar

    Svar: A. It is not built for people to stay in

    A confined space is not designed for continuous human occupancy, has limited entry or exit, and can be hazardous.

  2. Fråga 2 av 25

    Is a confined space always small?
    Visa svar

    Svar: D. No, it can be large, like a silo

    CCOHS notes that a confined space, despite its name, is not necessarily small. Silos and tanks can be very large.

  3. Fråga 3 av 25

    Which of these is most likely to be a confined space?
    Visa svar

    Svar: B. A storage tank

    Storage tanks are confined spaces. Ontario's guideline says offices, shops and walk-in freezers are designed for occupancy.

  4. Fråga 4 av 25

    Normal air contains about how much oxygen?
    Visa svar

    Svar: B. 21%

    Normal air is about 21% oxygen. Lower levels can cause collapse and death.

  5. Fråga 5 av 25

    Under Ontario's confined spaces rules, oxygen outside which range is an atmospheric hazard?
    Visa svar

    Svar: B. 19.5% to 23%

    Ontario treats oxygen below 19.5% or above 23% by volume as an atmospheric hazard.

  6. Fråga 6 av 25

    Why should you never use pure oxygen to freshen the air in a confined space?
    Visa svar

    Svar: D. Extra oxygen makes fires far more likely

    Too much oxygen greatly increases the risk of fire and explosion. CCOHS says never substitute oxygen for fresh air.

  7. Fråga 7 av 25

    Nitrogen, argon and carbon dioxide can be deadly in a confined space. Why?
    Visa svar

    Svar: A. They push out oxygen

    These simple asphyxiants displace oxygen. Unconsciousness or death can follow within minutes.

    Why is a problem inside a confined space more dangerous than the same problem in an open room?
    Visa svar

    Svar: C. Escape and rescue are much harder

    There is less margin for error, rescue and self-rescue are harder, ventilation is poor and conditions can change quickly.

  11. Fråga 11 av 25

    Svar: A. From outside, before anyone enters

    Air should be tested from outside the space before anyone enters.

Vanliga frågor

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.
