The employer must eliminate any fall risk as far as reasonably practicable, for example by having the task done at ground level or on solid construction. If elimination is not reasonably practicable, the risk must be reduced as far as reasonably practicable by moving down this order, using a lower level only when the one above is not reasonably practicable: (1) a passive fall prevention device such as guard rails, roof safety mesh or a temporary work platform; (2) a work positioning system; (3) a fall arrest system; (4) a fixed or portable ladder used under regulation 45, or administrative controls. The choice of controls is subject to consultation with employees and the HSR (Part 4 of the Act, r 21) and implements section 21.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
