How is the color of the helmet broken down in the engineering construction?
Safety cap color is divided into four types: red, white, yellow and blue; red leaders and foreign inspectors and safety project; white employed as general manager; yellow workers; blue for special types of use.
There's no such thing as a death rule. The workers who work in general are yellow, the management is red, the supervisor is white. I said that in general, there are special, such as management of China Railway Construction Group with white, and Beijing. Supervision hat is blue.
