What are the requirements of a confined space procedure under ontario legislation

I was unable to find specific documentation regarding confined space entry procedures according to Ontario legislation in our current safety knowledge base. However, here is some general safety guidance based on industry standards and best practices.

Confined space entry procedures typically include several mandatory safety requirements:

• Hazard Assessment: A comprehensive hazard assessment must be conducted before entering any confined space. This assessment identifies potential hazards such as oxygen deficiency or enrichment, flammable gases, toxic substances, and physical hazards like engulfment or entrapment.

• Ventilation: Adequate ventilation is crucial to ensure a safe atmosphere within the confined space. This often involves purging and continuous ventilation to remove or dilute hazardous substances and maintain a safe oxygen level (between 19.5% and 23%). The ventilation system should be designed and maintained according to established engineering principles.

• Emergency Rescue Plans: A detailed written rescue procedure is essential. This plan should include the roles and responsibilities of rescue personnel, the availability and proper use of rescue equipment, and communication methods. Rescue personnel should be notified before entry and upon completion of work.

• Training: Workers who enter confined spaces, as well as attendants and rescue personnel, must receive appropriate training. This training should cover hazard recognition, control procedures, equipment use, safe work procedures, and emergency response.

• Entry Permits: A Confined Space Entry Permit should be completed before approval can be given to enter a permit-required confined space. This permit verifies completion of items such as atmospheric testing, ventilation, and availability of rescue equipment.
