Access at Heights (Section 125)

125. (1) Where work cannot be done on or from the ground or from a building or other permanent structure without hazard to workers, a worker shall be provided with a scaffold, a suspended work platform, a boatswain’s chair or a multi-point suspended work platform that meets the requirements of this Regulation. O. Reg. 242/16, s. 9.
(2) A worker who is on or under a scaffold, a suspended work platform system or a multi-point suspended work platform while it is being erected, altered or dismantled shall be on a part of the scaffold, suspended work platform system or multi-point suspended work platform that meets the requirements of this Regulation. O. Reg. 242/16, s. 9.
• Suspended Work Platforms and Boatswain’s Chairs (Sections: 126-136.0.1)
R.R.O 1990, Reg. 851: Industrial Establishments

(a) the worker shall wear a serviceable safety belt or harness and lifeline that is adequately secured to a fixed support and so arranged that the worker cannot fall freely for a vertical distance of more than 1.5 metres; and
(b) the fall arrest system described in clause (a) shall,
(i) have sufficient capacity to absorb twice the energy and twice the load that under the circumstances of its use may be transmitted to it, and
(ii) be equipped with a shock absorber or other devices to limit the maximum arresting force to 8.0 kilonewtons to the worker. R.R.O. 1990, Reg. 851, s. 85; O. Reg. 420/10, s. 14.
