Guideline for working in confined spaces

Read this guideline to learn about employer and worker requirements when preparing to work in confined spaces safely.

As of July 1, 2011, the confined space requirements that were found in four sector-specific regulations under the Occupational Health and Safety Act (OHSA) have been consolidated into the Confined Spaces Regulation (O. Reg. 632/05).

The employer is responsible for ensuring that the requirements of OHSA and its regulations are complied with in the workplace. The employer must ensure that workers are protected, whether or not the confined space provisions apply.

Contravention of any of the requirements of the OHSA and its regulations is an offence which carries a maximum fine of $25,000 or imprisonment for a term of not more than twelve months, or both, for a person. The maximum fine for a corporation is $500,000 per offence.
