PART 6Levels of Lighting

Application

 This Part does not apply to the lighting of the bridge of a mobile offshore drilling unit, or of the bridge of any ship used for construction, production or diving or for geotechnical or seismic work.

  • (2) If it is not reasonably practicable to comply with subsection (1), the employer must provide portable lighting that gives the prescribed levels of lighting.

Measurement of Average Levels of Lighting

 For the purposes of this Part, the average level of lighting at a work position or in an area must be determined by taking four or more measurements at different places at the work position or in the area and by dividing the total of the results of the measurements by the number of measurements at the level at which the work is performed, in the case of the work is performed at a level higher than the floor or, at 1 m above the floor, in any other case.

Minimum Average Levels of Lighting

 The average level of lighting at a work position or in an area referred to in column 1 of an item of Schedule 1 must be not less than the average level set out in column 2 of that item.

Emergency Lighting Systems

  •  (1) If a failure in the lighting system in an area through which an employee passes in carrying out emergency procedures referred to in subsection 293(1) will cause the level of lighting to be reduced to less than 3 dalx, an emergency lighting system must be installed in the area.

  • (2) The emergency lighting system must

    • (a) operate automatically in the event of a failure of the lighting system; and

    • (b) provide an average level of lighting of 3 dalx.
