what is a confined space in bc

In British Columbia, confined space entry, hazards, and safety procedures are regulated under Part 9 of the Occupational Health and Safety Regulation (B.C. Reg. 296/97). These regulations outline the requirements for employers to ensure worker safety when entering and working in confined spaces. [1]

Key aspects of the regulations include:

• Confined Space Entry Program: Employers must establish and implement a written confined space entry program that includes assigning responsibilities, hazard assessments for each confined space, and written safe work procedures.
• Hazard Assessment: A qualified person must conduct a hazard assessment for each confined space or group of similar spaces, and for each work activity to be performed inside a confined space. The assessment must consider potential conditions and hazards such as oxygen deficiency or enrichment, flammable gases, toxic substances, engulfment, and other dangerous conditions.
• Written Procedures: Based on the hazard assessment, written procedures must be developed to eliminate or minimize all likely hazards.
• Entry Permits: An entry permit is required before a worker enters a confined space with a high hazard atmosphere, that requires lockout or isolation procedures, or in which there is a hazard of entrapment or engulfment. The permit must identify the confined space, work activities, workers inside the space, required precautions, and the permit's expiration time.
• Atmospheric Testing: Before entry, the atmosphere in the confined space must be tested by a qualified person to ensure it contains clean respirable air. Continuous monitoring is required in moderate or high hazard atmospheres.
• Ventilation: Confined spaces must be continuously ventilated while a worker is inside, except in specific circumstances such as intentionally inerted atmospheres or during emergency rescue.
• Standby Persons: Depending on the hazard level, standby persons must be assigned to monitor the well-being of workers inside the confined space and be capable of summoning rescue personnel or performing rescue duties.
• Rescue Procedures: Employers must provide for rescue services, and rescue personnel must be properly equipped and adequately trained. Practice drills must be conducted at least annually.
• Lockout and Isolation: Before entry, any material conveyance equipment must be free of material, and adjacent piping containing harmful substances must be disconnected or isolated using blanks, blinds, or a double block and bleed system.
