Danger - High Voltage Labels - Safety Signs by Caledonia Signs

“Danger – High Voltage” labels are critical safety warnings used to identify electrical equipment or areas where dangerous levels of voltage are present. These labels are designed to alert individuals to the risk of electric shock, burns, or even fatal injury if they come into contact with high-voltage systems. By providing a clear and immediate warning, they help prevent accidents and reinforce safe working practices.

The primary reason to use these labels is to protect personnel from electrical hazards and ensure compliance with workplace safety regulations and standards. High voltage systems require special precautions, and these labels help ensure that only qualified and authorised personnel approach or handle the equipment. The label acts as both a deterrent and a reminder to follow lockout/tagout procedures and wear appropriate personal protective equipment (PPE).

These labels are typically placed on or near switchgear, transformers, circuit breakers, control panels, high-voltage machinery, and fenced-off electrical areas. They are common in industrial facilities, power plants, substations, commercial buildings, and construction sites—anywhere high-voltage electricity is in use.

Using “Danger – High Voltage” labels promotes a culture of safety, reduces the risk of injury, and supports compliance with occupational health and safety regulations such as OSHA or IEC standards. They are an essential component of an effective electrical hazard communication program and help ensure a safer working environment for everyone.
