State Grid's Requirements for Color Weakness

State Grid has relatively strict requirements for the weak in recruitment, because color is of great significance in the power industry, such as identification and labeling of lines and equipment, drawing and analysis of graphics, etc. It is difficult for people with weak colors to correctly identify and understand different colors, which is easy to cause misoperation, misjudgment and safety accidents. Therefore, the State Grid generally requires that the personnel in the recruitment position need to pass a specific color vision test and have certain color vision standards.

Specifically, the state grid generally requires that the color vision test results of weak colors should not exceed a certain range. For example, the recruitment standard of red-green color blindness is that the color vision evaluation value is between 0.5 and 1. But for some non-special positions, such as administration and logistics, the weakness may be relaxed. It should be noted that different recruitment positions may have different requirements for the weak, and the specific requirements shall be subject to the announcement and recruitment information issued by the State Grid.
