The NHS recommends the following:
Electrical burns may not look serious, but they can be very damaging. Someone who has an electrical burn should seek immediate medical attention at an A&E department.
If the person has been injured by a low-voltage source (up to 220 to 240 volts) such as a domestic electricity supply, safely switch off the power supply or remove the person from the electrical source using a material that doesn't conduct electricity, such as a wooden stick or a wooden chair.
Do not approach a person who's connected to a high-voltage source (1,000 volts or more).
