2023-06-08

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.
