Part 9 Confined Spaces

See what's new!

Personal Protective Equipment and Other Precautions

9.46 Personal protective equipment

Repealed. [B.C. Reg. 312/2003, effective October 29, 2003.]

9.47 Emergency escape respirator

Workers entering a confined space which contains a high hazard atmosphere must carry on their person or have within arm's reach an emergency escape respirator sufficient to permit them to leave the confined space without assistance.

9.48 Compressed gas cylinders

A cylinder of compressed gas is not permitted inside a confined space, except for a cylinder of compressed air supplied to a respirator, medical resuscitation equipment, handheld aerosol spray containers, fire extinguishers, or other equipment permitted by the Board.

[Enacted by B.C. Reg. 253/2001, effective January 28, 2002.]

9.49 Torches and hoses

When practicable, torches and hoses used for welding, brazing or cutting must be removed from a confined space when not in use and when the confined space is vacated.

[Amended by B.C. Reg. 253/2001, effective January 28, 2002.]

Note: It may be impracticable to remove hoses for some short duration breaks of 60 minutes or less, particularly where the confined space is large or where the removal of hoses may create some risk to workers, for example, when hoses are removed from scaffolding. If removal is impracticable, alternate measures must be adopted under sections 9.4 and 9.5. The preferred method in most cases is to disconnect at source with safe venting procedures together with procedures to ensure no inadvertent reconnection while workers are on the break or, if this is not practicable, closing and putting a tag on connections located outside the confined space. Other applicable requirements in Part 9 must also be followed including those on ventilation, standby persons and retesting prior to re-entry. For further information, see the OHS Guideline on section 9.49 at

9.50 Electrical equipment

(1) Electrical tools and equipment used in a confined space must be grounded or double-insulated and so marked, and if wet or damp conditions exist inside the space, must be protected by an approved ground fault circuit interrupter as required by Part 19 (Electrical Safety).

(2) Electrical tools and equipment used in a confined space where flammable vapours of explosive gases, or liquids are present must be CSA approved for hazardous locations classified under CSA Standard C22.1-94, Canadian Electrical Code Part 1, as Class 1, Division 2, Groups A, B and C.

9.51 Non-sparking tools

Only non-sparking tools may be used in a confined space where flammable or explosive gases, vapours or liquids are present.
