You must ensure that no one working under your control goes onto or near a fragile surface unless that is the only reasonably practicable way for the worker to carry out the work safely, having regard to the demands of the task, equipment or working environment.
If anyone does work on or near a fragile surface, you must:
- ensure (SFAIRP) that suitable platforms, coverings, guard rails, etc. are provided (and used) to minimise the risk; and
- do all that is reasonably practicable, if any risk of a fall remains, to minimise the distance and effect of a fall.
If anyone working under your control may go near a fragile surface, you must do all that is reasonably practicable to make them aware of the danger, preferably by prominent warning notices fixed at the approaches to the danger zone.
