When to choose demarcation
A good fit when
- Work stays well away from the edge
- You need a safe zone marked quickly
- The layout changes between jobs
- Budget or timescale rules out fixed guardrail
Consider instead
- Rooftop Guardrail (Kee Guard®) Work happens at or near the edge
- Narrow-space guardrail A tight margin that needs a full barrier
- Rooftop lifeline Workers need to reach the edge itself
FAQs
Questions about pathway guidance system
How far from the edge demarcation sits, how it differs from a guardrail, and indoor use.
How far from the edge should demarcation be?
At least 2 m from the edge of a roof or other hazard.
Is demarcation the same as a guardrail?
No. Demarcation marks the boundary of a safe working area and gives a physical and visual warning. Where people need to work at the edge, a guardrail or lifeline is needed.
Can it be used indoors?
Yes. Kee Mark suits interior and exterior use, such as warehouse mezzanines and plant areas.
