In Saskatchewan, a confined space is defined as an enclosed or partially enclosed space that is not primarily designed for continuous human occupancy, but may be used for work, and has restricted means of entry and exit.  Confined spaces can pose various risks, including oxygen deficiency, flammable or explosive atmospheres, toxic substances, and the potential for someone to become trapped. Employers must conduct risk assessments, implement control measures, and provide training for workers before entering a confined space.
