What is a Confined Space?


The Alberta Occupational Health and Safety Code defines a confined space as:

"A confined space means a restricted space which may become hazardous to a worker entering it because of:
(a) an atmosphere that is or may be injurious by reason of oxygen deficiency or enrichment, flammability, explosivity or toxicity,
(b) a condition or changing set of circumstances within the space that presents a potential for injury or illness, or
(c) the potential or inherent characteristics of an activity which can produce adverse or harmful consequences within the space.”

Confined spaces pose a significant risk of injury and death, in the workplace. 
Confined space incidents can happen suddenly, often without any warning that something is wrong.  Therefore, it's important that employers take the necessary steps to ensure worker safety around confined spaces. 
You, as the worker, must always follow the guidelines, set out by your employer, to ensure you are kept safe around confined spaces.
