(c) into operating machinery or moving parts of the machinery;
(d) into water or another liquid;
(e) into or onto a hazardous substance or object;

14.3 Subject to section 14.6, an employer must ensure that a guardrail system is used where there is a risk of a worker falling in any of the circumstances set out in subsection 14.1 (1)
14.4
(1) An employer must ensure that a guardrail
(a) is at least 900 mm high and not more than 1,060 mm above the working surface, with an intermediate rail at between 450 and 530 mm above the working surface; and
(b) is constructed and secured to resist a static load of 900 N in any direction in which the load may be applied at any point on the top rail and on any intermediate rail.
(2) A guardrail must have a toe board securely fastened to the posts and extending from the surface of the working area to a height of at least 125 mm when there is a risk of falling objects.
(3) If a guardrail is made from wood, it must
(a) be free from splinters and protruding nails; and
(b) have a top and mid rail of at least 38 mm × 89 mm securely supported on posts of at least 38 mm × 89 mm and spaced at not more than 2.4 m.
14.5 An employer may temporarily remove a guardrail when it is necessary to do so to facilitate work in the immediate area. The employer must ensure that any worker in the area uses a fall protection system while the guardrail is removed.

14.14
(1) The owner of a building or structure must ensure that a permanent anchorage system used as the fixed support in a travel restraint system or fall arrest system for that building meets the following requirements:
(a) the anchor has an ultimate capacity of at least 22.2 kN in any direction in which the load may be applied for each worker attached;
(b) the anchorage system is certified by a professional engineer as having the required load capacity;
(c) where the anchorage system is used in conjunction with a suspended work platform, the system is designed, constructed and used in accordance with CAN/CSA Standard-Z91-02, Health and Safety Code for Suspended Equipment Operations and CAN/ CSA-Z271-10 (R15), Safety code for suspended platforms.
(2) When a permanent anchorage system cannot be used at a workplace, an employer must ensure that the temporary fixed support in a travel restraint system or fall arrest system meets the following requirements:
(a) when a fall arrest system without a shock absorber is used, a support used in a fall arrest system must be capable of supporting a static force of at least 8 kN without exceeding the allowable unit stress for each material used in the fabrication of the anchor point;
(b) when a shock absorber is used in a fall arrest system, the support must be capable of supporting a static force of at least 6 kN without exceeding the allowable unit stress for each material used in the fabrication of the anchor point;
(c) a support used in a travel restraint system must be capable of supporting a static force of at least 2 kN without exceeding the allowable unit stress for each material used in the fabrication of the anchor point.

14.22
(1) When a worker uses a horizontal lifeline system, an employer must ensure that the specifications for the system are kept at the worksite and are readily accessible by a worker.
(2) The specifications for a horizontal lifeline system must address the following issues:
(a) the arrangement of the system, including the anchorage or fixed support system;
(b) the components used;
(c) the number of workers that can safely be attached to it;
(d) the instructions for installation or erection;
(e) the maximum load capacity of the system.
(3) When a permanent horizontal lifeline system from a manufacturer is installed at a workplace, an employer must ensure that, before the system is put into use, the system is certified as being properly installed according to the manufacturer’s specifications by one of the following:
(a) the manufacturer;
(b) a person authorized by the manufacturer;
(c) a professional engineer.
(4) When a permanent horizontal lifeline system designed by a professional engineer is installed at a workplace, the employer must ensure that, before the system is put into use, the system is certified as being properly installed according to the engineer’s specifications by a professional engineer.
