Demarcating safe areas
“Where work is not done at the edge, demarcation barriers can be provided at a safe distance from the edge (usually at least 2 metres). e.g. work on an air-conditioning unit in the middle of a roof. Barriers should be visible and obvious “
L24; Health and Safety in Construction: HSG 150 (3rd edition); Health and Safety in Roof work: HSG33.
Schedule 2 of the (WAHR) covers the requirements for guardrails, toe boards or other similar barriers.
“Full edge protection may not be necessary if limited work on a larger roof involves no body going any closer than 2m to an open edge. In such cases demarcated areas can be set up, outside which nobody goes during the work or access to it. Demarcated areas should be:
• Limited to areas from which nobody can fall
• Indicated by an obvious physical barrier (full edge protection is not necessary but a painted line or bunting is not acceptable)”

The Working at Height Regulations 2005 (WAHR) Part 3 Legal Requirements p34
Shows the use of a system of demarcation located away from a fall hazard as an “example of other additional, suitable and sufficient means to prevent a fall”
