The decision to use electrical gloves should be made with extreme caution; they should only be used when dealing with low-voltage electricity supplies. Low voltage is defined as voltage up to 1000V AC or 1500V DC.
Where it is necessary to come into contact with low-voltage electricity, electrical gloves should be worn, for example, when removing people from contact with electricity.
Where there is high-voltage electricity (greater than 1000V AC or 1500V DC), or it is not possible to verify the actual voltage, the only safe course of action is to ensure that the supply is cut off and declared safe by a competent person.
