What do the different colors of safety helmets represent, and what is their meaning? Why aren’t there green helmets?

Refining and chemical enterprises: Red represents personnel in on-site operational service roles, yellow represents safety management personnel, white represents personnel in charge of process equipment and other management tasks, and blue represents personnel from maintenance and repair units

Our LNG: Red represents on-site safety managers, yellow represents operators, white represents process equipment and other managers, and blue represents personnel from maintenance and repair units

{:3_50:} Is there a standard for this? Yellow for operators, blue for maintenance personnel, red for leaders, white for security personnel. @Guan Gongyu @Fish in the Desert

We are yellow for operators, blue for maintenance personnel, red for middle-level managers, and white for senior managers and safety personnel

**Relevant standards do not provide guidelines regarding the colors to be used for safety helmets; different industries, systems, and companies have their own rules. Here are some examples of typical color codes: In the construction industry, burgundy is used for supervisors, red for technical staff, white for safety inspectors, blue for electricians or supervisors, and yellow for other construction workers. In the state power sector, white is used for supervisors, blue for management staff, yellow for construction workers, and red for outsiders. In the oil industry, white is used for management staff, yellow for safety inspectors, and red for operators. Safety helmets play a crucial role for maintenance and operational personnel, as they directly affect the life safety of those working on the front lines – this is by no means an exaggeration, especially when it comes to maintenance workers. The requirements for safety helmets include not only a reasonable structure, comfort, but also a striking color.

In the past, sanitation workers wore green hats, but due to cultural taboos among the local population, that practice has ceased. In the Middle East, security personnel wear green hats, while fire trucks are yellow-green in color

I have an idea: how about holding an event on “common construction problems”?~

Our factory: Yellow: regular operators; Red: managers; White: senior executives
