Danger - High Voltage - Safety Signs by Caledonia Signs

A critical safety warning used to alert people to the presence of electrical equipment or areas where dangerously high voltages exist. High voltage electricity can cause severe injury, electric shock, burns, or even death if proper precautions are not taken. The sign serves to clearly communicate this risk and to keep unauthorised or untrained individuals away from hazardous electrical installations.

You’ll often see this sign on electrical substations, transformer enclosures, switchgear rooms, power distribution panels, or near overhead and underground power lines. Its presence reminds workers, visitors, and the general public that the area contains potentially lethal electrical energy and that strict safety protocols must be followed. This includes not touching electrical equipment, obeying lockout/tagout procedures, and using appropriate personal protective equipment.

In addition to protecting human safety, the “Danger – High Voltage” sign helps organisations comply with health and safety regulations, which require clear identification of electrical hazards to minimise accidents and liability. By prominently displaying the warning, businesses demonstrate their commitment to safety and encourage a culture of awareness and caution around electricity.

Overall, the “Danger – High Voltage” sign plays an essential role in preventing electrical accidents by making the invisible hazard visible. It informs and warns everyone in the vicinity to take necessary precautions, ensuring that high-voltage areas are approached with respect and care to maintain a safe environment for all.
