Caution High Voltage Keep Out No Entry Signs
Caution High Voltage Keep Out No Entry Signs warn workers and visitors of dangerous electrical equipment and clearly restrict access to hazardous areas. The multi-message design combines a high voltage warning with keep out and no entry instructions, helping prevent unauthorised entry into electrical rooms, substations and industrial workplaces.
Where & How to Use
Install this high voltage warning sign at entrances to electrical rooms, substations, switchgear areas and plant equipment zones where dangerous voltage is present. Position near access points, control panels or fenced electrical areas so workers and visitors clearly see the warning and understand that entry is restricted.
