In the operating state of the equipment, the green signal flash indicates that the equipment is in a state of readiness for operation, the red signal light indicates that the equipment is being put into operation, to remind the staff to concentrate and pay attention to safe operation. Electricity Safety Regulations" (power plants and substations electrical part) clearly stipulates the use of hanging signs and installing cover rails on different occasions: (1) in the once closed to send power to the place of work of the switch and the knife gate operating handle, should be hung in red letters on a white background, "prohibit closing the gate, someone is working," signage.

Signage.
"STOP, HIGH VOLTAGE DANGER" signage is in the form of a white background with red edges and red arrows
No climbing, high voltage danger!
Practice has proved that the safety color is very important in the work of the substation production, in order to your safety and the safety of others, please keep in mind the meaning of these safety colors, and in the actual work of the correct application.
In the safety color code with red to indicate prohibited, stop or fire
Safety colors for electric power work are the colors that indicate the meaning of safety information. The use of safety color can make the human sensory adaptability in the long-term life formed and fixed for life and work, the purpose is to make people through the bright colors can quickly find and distinguish the safety signs, remind people to pay attention to prevent accidents.
