Dielectric Boots
Electrically Insulating Boots for High Voltage Workers

Dielectric boots are electrically insulating and used where there is a risk of electric shock from high voltages. Without the the correct PPE a high voltage electric current can stop the heart or produce fatal burns. For this reason, every single pair of Workmaster™ Dielectric Boots undergoes a high voltage test before it leaves the factory.

Dielectric boots are used for working on live high-voltage power or in the area of live power, as current can jump large distances, especially in wet or damp conditions. Even when high voltage equipment has been switched off, there may be a residual charge on the equipment which could cause an injury. There have also been fatalities caused by digging in locations where power cables are buried underground and the cable has been inadvertently cut by a drill, shovel or mole.
