The employer must review, and revise if needed, its manual handling controls: before any change to a thing, process or work system that involves hazardous manual handling (relocating that work included); when new or extra information becomes available; when an employee, or someone for them, reports an MSD; after any incident under Part 5 of the Act involving hazardous manual handling; whenever controls are not adequate; and when the HSR asks. The HSR may ask if they reasonably believe any of those triggers exists or the employer failed to review properly or ignored a trigger.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
