2.10.15. Anchorage system:
The fall arrest connecting device of a safety harness must be secured to (1) a single point of anchorage with one of the following characteristics:
(a) a breaking strength of at least 18 kN; or
(b) designed and installed in accordance with an engineer’s plan in compliance with CSA Standard Z259.16 Design of Active Fall-Protection Systems, and having one of the following characteristics:
i. a strength equal to twice the maximum fall arrest force as certified by an engineer; or
ii. certified in accordance with EN 795 Personal Protective Equipment against Falls - Anchor devices - published by the European Committee for Standardization or with CAN/CSA Standard Z259.15 Anchorage Connectors;
(2) a flexible continuous anchorage system (horizontal life line) with one of the following characteristics: (a) in compliance with the following minimum standards:
i. a steel cable of a minimum diameter of 12 mm slackened to a minimum angle of 1 vertical to 12 horizontal, or 5 ° from horizontal;
ii. a maximum distance of 12 m between the end anchors;
iii. end anchors with a breaking strength of at least 90 kN;
iv. not to be used by more than 2 workers at a time;
(b) designed and installed in accordance with an engineer’s plan in compliance with CSA Standard Z259.13 Flexible Horizontal Lifeline Systems and CSA Standard Z259.16 Design of Active Fall-Protection Systems;
(3) a rigid continuous anchorage system designed and installed in accordance with an engineer’s plan in compliance with CSA Standard Z259.16 Design of Active Fall-Protection Systems.
An anchorage system:
(1) must be designed so that the D-ring of the suspension point of a worker’s safety harness cannot be moved horizontally by more than 3 m or an angle of 22 °;
(2) cannot be used by more than 1 person at a time, except in the case of a continuous anchorage system, such as a horizontal life line, or a rigid anchorage system, such as a rail; and
(3) must be designed so that properly attached personal protective equipment cannot be detached involuntarily.
The structure on which the anchorage system is installed must be able to withstand the effort exerted by the anchorage system in addition to the other efforts that it must ordinarily withstand.
An anchorage system with the characteristics described in subparagraph b of subparagraph 1 or 2 of the first paragraph, or in subparagraph 3 of that paragraph, must, before it is first brought into service, be inspected and tested by an engineer or a qualified person acting under the supervision of an engineer, to ensure that the system is in compliance with the design and installation plans.
