Confined space training introduces workers to the hazards, risk assessment processes and safety procedures associated with confined spaces. It typically covers hazard recognition, control measures, entry procedures and emergency planning. The exact training and workplace requirements can vary across Canadian jurisdictions.

A confined space is generally an enclosed or partially enclosed area that is not designed for continuous human occupancy and has restricted entry or exit, while potentially presenting health or safety risks. Examples can include tanks, silos, manholes, vaults, pipes and sewers.

Confined spaces can involve atmospheric hazards such as oxygen deficiency, toxic gases and flammable atmospheres. Other risks can include fire, engulfment, electrical hazards, moving equipment, falls and difficult evacuation. Conditions can also change while a worker is inside the space.

Risk assessment helps identify hazards before workers enter a confined space and supports decisions about appropriate control measures. Canadian guidance recommends assessing the space, considering hazards that may develop during work and establishing procedures before entry.

Confined space requirements exist across Canadian jurisdictions, but the specific rules, training requirements and procedures can differ by province, territory or federal jurisdiction. Workers and employers should follow the legislation and workplace procedures that apply to their location and type of work.

Yes. OTA’s confined space course is delivered online and is designed for self-paced learning. Learners can study from a compatible computer, tablet or mobile device and retain lifetime access to the course. However, online theory should not be assumed to replace any workplace-specific, equipment-based or rescue training required for a particular role.
