Therefore, for the safety helmets used in general technical jobs, milky white, light yellow, and light green are suitable. For mining safety helmets, the coal mining industry habitually chooses black colors. This should be because the dust is black and the pollution safety helmets cannot be seen , while other colors are easily detectable.
However, the mining safety helmet is gray-black, which obviously does not meet the safety ergonomics standards. Due to the weak lighting in the mine, when the gray-black mining helmet is inconspicuous in color contrast, it is very easy to cause safety accidents due to blurred vision. Therefore, soft tones should be used, which is conducive to detection and alertness. Now mining hats have other colors besides black, and reflective materials or optical materials are attached to the helmets so that they can attract public attention under dark lights.
Some units use safety helmets of different colors to distinguish their positions. For example, security personnel wear safety helmets with a white background marked with emerald green crosses, and maintenance personnel wear orange safety helmets. In forest harvesting workplaces, bright red or orange-red safety helmets are conspicuous and easy to be discovered. For radioactive material construction environments, blue-purple and coffee-colored safety helmets are generally used. For flammable and explosive materials, bright red safety helmets are commonly used.
