Dear Friends,
Nice discussion.
Let me write a few points.
Color coding is not available any where internationally. Each company has its choice made on the recommendation of HSE/Security and Administration.
How ever from the point of ergonomics the following points are guidelines for selectors.
In the man-machine-environment system, we learn that man responds to a given stimulus.
For many situations, a generalized response is given. Most Indians, for example, expect a light switch to be turned by flipping the light switch “down” and off by a “up” movement. Whereas most Americans, expect a light switch to be turned by flipping the switch “up” and off by a “down” movement. A clockwise motion generally refers to an increase.
Such responses are called “population stereotypes,” a behavior response common to nearly everyone in the population.
In occupational safety population stereotypes are particularly important from the point of view of hazard identification and recognition through various warning systems. Ideally, a visual or auditory warning system should make use of known associations for words (Danger, Caution, and Warning) and colors (red, yellow, green, blue) in specifying the degree of hazard associated with a specific industrial condition. For example, research on accident prevention signs as specified in American National Standard Specifications for Accident Prevention signs Z35.1 has demonstrated that workers do associate different degrees of hazard with various visual hazard alert cues. Thus danger signs (color coded red) elicit higher amount of hazard association than with Caution signs (color coded yellow). Likewise THINK signs (color coded green) elicit higher amount of hazard association than NOTICE signs (color coded blue).
It can be very useful to have different colours or helmet shape to identify the category of personnel on the site (construction site, plants, etc.). It can also be important for the security and/or for the internal organization to easily make the difference between :
- Production workers and operators
- Supervisors
- Plant / department managers
- Security officers
- Maintenance technicians Etc.
- Emergency personnel Etc.
Helmets can additionally be customized with logos or stickers for an even easier identification.
The clue:
1. Fire extinguishers, Fire warnings etc are red. What color helmet you will have to choose for fire fighter’s helmet ?.
2. Green cross, Green triangle etc for Safety logos internationally. What color you will prefer for helmets to safety staff ?
It is only up to your company to choose, based on recommendations received from respective departments. Have you got a say in it as a safetyman ?
