Part 9 Fall Protection

Section 152.1 Anchor strength – temporary

Subsection 152.1(1) Temporary travel restraint anchor

In temporary applications, travel restraint anchors must be designed to have a minimum breaking strength of 3.5 kN (800 lbs) and be installed, used and removed according to the manufacturer’s specifications or specifications certified by a professional engineer.

To prevent a worker from confusing a travel restraint anchor with an anchor intended for fall arrest, the temporary anchor must be permanently marked as being for travel restraint only. Upon completion of the work project or within the time period specified by the manufacturer or professional engineer, the anchor must be removed so it is not forgotten and, over time, permitted to deteriorate to the point that it is unable to provide the expected degree of protection.

Subsection 152.1(2) Temporary fall arrest anchor

Temporary fall arrest anchors such as wire rope slings, synthetic webbing slings, I-beams sliders, I-beam clamps, etc. must have a minimum breaking strength of

(a) at least 16 kN (3600 lbs) per worker attached, in any direction required to resist a fall, or
(b) two times the maximum arresting force per worker attached, in any direction required to resist a fall.

Temporary fall arrest anchors must be installed, used and removed according to the manufacturer’s specifications or specifications certified by a professional engineer. Upon completion of the work project or within the time period specified by the manufacturer or professional engineer, the anchor must be removed so it is not forgotten and, over time, permitted to deteriorate to the point that it is unable to provide the expected degree of protection.
