Section 33 Disposition versions

33. Operating conditions: Scaffolds shall be designed for the type of work to be performed and the probable risks. They shall meet the following conditions:

(1)  be so designed, constructed, trussed, braced and maintained as to support any loads and stresses they may be subjected to, and resist wind action;

(2)  have a safety factor of at least 4 for each constituent element;

(3)  rest on firm ground or foundations;

(4)  be provided with guardrails when the workers are at risk of falling

(a)  into a liquid or dangerous substance;

(b)  from a height of 1,5 m or more in a well, a basin, a tank, a reservoir, a vat, a container for the storing or mixing of substances, or where the workers are handling a load; or

(c)  from a height greater than 3 m in other cases.

Despite subparagraph 4, a guardrail is not required for each of the sides of a scaffold floor located less than 350 mm from a wall or another floor.

The guardrails of the scaffolds may be temporarily removed if they prevent the carrying out of work that cannot reasonably be performed otherwise. In this case, the wearing of a full body harness secured to an anchorage system by a fall arrest connecting device is mandatary for the worker, in accordance with section 347.
