Danger - 400 Volts - Labels - Safety Signs by Caledonia Signs

These labels are safety warnings used to clearly identify electrical equipment or circuits operating at 400 volts, a level of voltage that poses a serious risk of electric shock, burns, or even fatal injury if not handled correctly. These labels serve as an essential visual alert to ensure that anyone working near the equipment is aware of the electrical hazard present.

The primary reason to use these labels is to promote electrical safety and prevent accidents in environments where high-voltage equipment is used. Clearly marking areas or devices with “Danger - 400 Volts” helps ensure that only qualified and authorised personnel handle or maintain the equipment, and that they do so following strict safety protocols, such as using personal protective equipment and following lockout/tagout procedures.

These labels are typically applied to electrical panels, distribution boards, switchgear, industrial machinery, motor control centres, and any other equipment or installations operating at 400 volts. They are commonly found in industrial settings, large commercial buildings, and facilities where three-phase power systems are standard.

Using “Danger - 400 Volts” labels helps organisations comply with electrical safety regulations, minimises the risk of accidental contact, and supports a safe working environment. By clearly identifying voltage hazards, these labels contribute to injury prevention and overall workplace safety.
