The law says that contractors and employers must manage the danger by avoiding work on or near fragile surfaces and controlling any remaining risk by use of stagings, guard rails, and fall arrest systems.

On business premises contractors should work closely with the client and agree arrangements for managing the work.
Falls through fragile surfaces, particularly fibre-cement roofs and rooflights, account for 22% of all fall from height fatal injuries in the construction industry.
