Colour Coding
Clear identification of hazardous machine parts, obstructions, pipes and services enables speedy recognition and, where necessary, immediate warning of danger.
- A defined system of colour coding can be used to indicate hazardous and non-hazardous piping, designated areas, first aid and fire-fighting facilities and equipment, processing and storage areas, walkways, and can also include specific colouring of containers and drums, etc.
- Remember though that the marking of a physical hazard by a standard colour warning is not a substitute for complete elimination of the hazard. But it can supplement the proper guarding of machinery and other methods of eliminating hazardous conditions. A legend is needed to identify colours. This should be prominently displayed at strategic positions and all crew made aware of the meaning of the different colours used.
Labelling
It is important that critical valves, switches, isolators, etc are fully identified and labelled, so that only the correct equipment or process is operated in an emergency.
- Comprehensive, but easily understood labelling is also critically important so that emergency responders unfamiliar with a specific operation can clearly understand what to do – such as starting an emergency generator for instance. Instructions must be clear, and the relevant switches, valves, etc.so clearly marked that system operation is easily and safely affected.
- Labelling should be straight-forward and practical.
- Photo luminescent signs and labels make the task of providing information in the dark very much easier.
