Section 26.3, subsection (3) states,
“The guardrail system or protective covering required under subsection (1) or (2) may be removed temporarily to perform work in or around the opening if a worker is adequately protected and signs are posted in accordance with subsections 44(1) and (2).”
Section 44 states,
“Signs meeting the requirements of subsection (2) shall be posted in prominent locations and in sufficient numbers to warn workers of a hazard on a project and any sign shall contain the word “DANGER” written in legible letters, 150 millimetres in height and shall state that entry by any unauthorized person to the area where the hazard exists is forbidden.”
Section 26.3, subsection 4 states,
“The following are the specifications for a guardrail system:
1. It shall have a top rail, an immediate rail and a toe board.
2. The intermediate rail may be replaced by material that can withstand a point load of 450 newtons applied in a lateral or vertical downward direction.
3. Subject to subsection 116 (8) the top of the guardrail system shall be located at least 0.9 metres but not more than 1.1 metres above the surface on which the system is installed.
4. The intermediate rail shall be located midway between the top rail and the toe board.
5. If the guardrail system is located at the perimeter of a work surface, the distance between the edge of the surface and the guardrail system shall not be greater than 300 millimetres.”
Guardrail systems must meet certain stress requirements. The intermediate rail must be able to withstand forces around the 100 foot pound area. There is even an additional requirement to remove a guardrail temporarily. One must attach signs in large quantities and in conspicuous locations to prevent any other persons from entering the hazard area. The signs must meet certain standards when being made up, large enough to get everyone’s attention.
The Ontario government and the MOL, they do attempt to think of everything.
As a reminder, if it needs to be removed, temporarily, ensure that the enough signs are posted at key critical areas to prevent any other employees from entering the hazardous area. Do not forget that the MOL expects all employers to protect their workers every step of the way.
Remember — In Ontario, “ALL Accidents are Preventable”
‘Work’ and ‘Play’ safe.
