CONFINED SPACE HAZARDS CANADA ONLINE COURSE OVERVIEW
If one of your co-workers were to pass out in a confined space, are you equipped to rescue him? Can you tell if the air in the space is safe? This course will help you understand the risks associated with confined spaces and the procedures your employer has in place to protect you and those around you.
Every year, people are injured or killed as a result of improperly entering or working in a confined space. Potential hazards in confined spaces include explosions, toxins, and oxygen-deficient atmospheres. An average of 20 people a year die from confined space hazards, and more than half of the fatality victims are would-be rescuers.
Because confined spaces may be encountered frequently in construction work, construction workers must be able to recognize confined spaces and understand their hazards. Designed for anyone who works in or around confined spaces, this course and the information it contains might be the difference between life and death.
This online Confined Space Hazards Canada course covers the following topics:
- Recognizing confined spaces
- Confined space hazards
- Understanding the risks of confined spaces
- Employer responsibilities regarding confined spaces
- The responsibilities of confined space authorized entrants, attendants, and entry supervisors
- The differences in flammable, toxic, irritant or corrosive, and asphyxiating atmospheres
- Procedures for dealing with confined spaces
- How to deal with oxygen-deficient atmospheres
- How to protect yourself and others

Additional Safety Knowledge
What Alberta OHS Defines as a Confined Space
Alberta OHS Code Part 5 defines a confined space as an enclosed or partially enclosed space that is not designed for continuous human occupancy, has limited or restricted entry, and could contain a hazardous atmosphere, engulfment hazard, entrapment hazard, or any other recognised serious safety or health hazard. Examples include storage tanks, sewers, silos, pipelines, boilers, vaults, tunnels, manholes, pits, and process vessels.
Atmospheric Testing Before Entry
Before any entry, a competent worker must test the atmosphere in this order: oxygen, flammability, then toxicity. Acceptable atmospheric parameters:
- Oxygen: 19.5–23.0% by volume. Below 19.5% is oxygen-deficient; above 23% is oxygen-enriched (fire risk).
- Flammable gas/vapour: less than 10% of the lower explosive limit (LEL).
- Toxic substances: below the applicable occupational exposure limit (H2S below 10 ppm, CO below 25 ppm in Alberta).
Continuous monitoring is required for the duration of the entry. Any change in reading requires immediate evacuation and re-assessment.
Entry Roles: Entrant, Attendant, Supervisor
Every confined space entry needs three defined roles. The entrant performs the work inside. The attendant stays outside, maintains constant visual or communication contact, monitors atmospheric readings, and initiates rescue — but never enters. The entry supervisor authorises the entry, verifies all controls are in place, and terminates the entry when conditions change. In Alberta, the attendant cannot leave the post while any worker is inside.
Confined Space Hazards For Canada — Rescue Planning
OSHA data shows more than 60% of confined space fatalities are would-be rescuers who entered without proper training or equipment. Non-entry rescue (retrieval systems, tripods, winches) must be planned wherever practical. If entry rescue is required, a trained rescue team with SCBA, communications, and defined rescue procedures must be on-site or immediately available before entry begins.
