3.9.8. Platforms: The components of the platforms shall be laid in such a way as to prevent any toppling or sliding. In addition, scaffolding platforms shall:(1) have a uniform surface between two fulcrum points;
(2) have a minimum free width of 470 mm;
(3) if made of lumber, be constructed of planking:(a) stamped by a body certified by the Canadian Lumber Standards Association as being of quality equivalent to No. 1 spruce;
(b) measuring at least 50 mm × 250 mm;
(c) long enough to extend at least 150 mm but not more than 300 mm beyond the end supports; if they are fixed end to end, their extremities shall rest on individual fulcrum points;
(d) laid in such a way as the span between 2 fulcrum points does not exceed:i. 3.0 m if they are tested and stamped in accordance with Division 11 of CAN/CSA Standard S269.2-M87 Access Scaffolding for Construction Purposes;
ii. 2.1 m in any other case;
(e) whose deflection in the middle of the span does not exceed L/80 where L is the distance between 2 fulcrum points;
(4) if made of manufactured products, be:(a) built in accordance with CAN/CSA Standard S269.2-M87 Access Scaffolding for Construction Purposes;
(b) worked so as to avoid slipping;
(c) maintained to avoid corrosion and deterioration;
(5) before each use, be visually inspected in order to detect any alteration that may affect its solidity;
(6) have a slope of less than 1:5 (11º from the horizontal plane); and
(7) be located less than 350 mm from a wall or other platform if there is no guardrail.
