Safety Labels: British Pipe Marking Standards
Written by Steve Hudgik
Color coding helps to identify the danger levels of pipes and valves
The British Standard BS 1710 outlines how pipes, conduits, and ducts must be labeled so that they are easily identifiable.
The Health and Safety Regulations for Safety Signs & Signals require visible pipes that contain or transport dangerous substances be labeled. Using col our to identify the contents of pipes, conduits, and ducts should follow the British Standard BS 1710. Standardization of pipe marking will avoid possible confusion, injury, and other hazardous incidents.
Pipe Markers must be applied to the following locations:
- Pipework leading into and away from a manifold system.
- Within one metre of pipework passing through a wall.
- On all pipework in a loading gantry, adjacent to the flow-meter for each pipe.
- Within one metre of hose connection points.
- Get a free pipe marker guide for the full list.
Col ours to use to identify pipelines and services in accordance with BS1710: 1984
