Definition
Work at height is any work where a person could fall a distance liable to cause injury, on scaffolds, roofs, ladders or ropes, and it needs planning, a permit and fall protection.
Why it matters on a project
The order of control is clear: avoid work at height where possible, then prevent falls with barriers, then reduce the consequences with harnesses and nets.
Common mistake
Clipping a harness to an anchor point not designed to take a fall load.
Frequently asked questions
What height counts as work at height?
Any height from which a fall could cause injury; regulations and site rules set the detailed requirements.
Is a harness enough on its own?
No. It needs a suitable anchor, a suitable lanyard, a rescue plan and training.
