General protection

139

(1) An employer and a supervisor must ensure that a worker is protected from falling if a worker may fall,

(a) at a temporary or permanent work area, a vertical distance of 3 metres or more,
(b) at a temporary or permanent work area, a vertical distance of less than 3 metres if there is an unusual possibility of injury,
(c) at a temporary or permanent work area, into or onto a hazardous substance or object, or through an opening in a work surface, or
(d) at a permanent work area, a vertical distance of more than 1.2 metres and less than 3 metres.

(2) For the purposes of this section, there is an unusual possibility of injury if the injury may be worse than an injury from landing on a solid, flat surface.

(3) Subject to subsection (5), an employer must install a guardrail.

(4) Repealed.

(5) Subject to subsection (6), if the use of a guardrail is not reasonably practicable, an employer and a supervisor must ensure that a worker uses a travel restraint system that meets the requirements of this Part.

(6) Subject to subsection (7), if the use of a travel restraint system is not reasonably practicable, an employer and a supervisor must ensure that a worker uses a personal fall arrest system that meets the requirements of this Part.

(7) If the use of a personal fall arrest system is not reasonably practicable, an employer and a supervisor must ensure that a worker uses equally effective controls.

(8) A worker must use a fall protection system as required by this section.

Covering openings

(1) An employer must ensure that an opening or hole through which a worker can fall is protected by

(a) a securely attached cover designed to support an anticipated load, or
(b) guardrails and toe boards.

(2) If a person removes a cover, guardrail or toe board, or any part thereof, protecting an opening or hole for any reason, an employer must ensure a temporary cover or other means of protection replaces it immediately.

(3) If a temporary cover is used to protect an opening or hole, an employer must ensure a warning sign or marking clearly indicating the nature of the hazard

(a) is posted near or fixed on the cover, and
(b) is not removed unless another effective means of protection is immediately provided.

Guardrails

315

(1) An employer must ensure that a guardrail required by this Code

(a) has a horizontal top member installed between 920 millimetres and 1070 millimetres above the base of the guardrail,
(b) has a horizontal, intermediate member spaced mid way between the top member and the base,
(c) has vertical members at both ends of the horizontal members with intermediate vertical supports that are not more than 3 metres apart at their centres, and
(d) is constructed of lumber that is 38 millimetres by 89 millimetres or of material with properties the same as or better than those of lumber.

(2) Despite subsection (1), a temporary guardrail does not require a horizontal intermediate member if it has a substantial barrier positioned within the space bounded by the horizontal top member, toe board and vertical members that prevents a worker from falling through the space.

(3) An employer must ensure that a guardrail is secured so that it cannot move in any direction if it is struck or if any point on it comes into contact with a worker, materials or equipment.
