Electrical Shock

Electric shock is the most obvious hazard associated with working around energized components and machinery. An electric shock may cause a miner's muscles to contract and adhere to an electrical component. A miner must never attempt to remove another miner who appears to be receiving a shock. Instead, he or she must de-energize the electrical components before removal of the victim. If this is not possible, the miner attempting to help must use an insulated device, such as a rubberized glove or baton, to attempt to remove the victim from the source of the power.

As an electrical current travels through the body, it can cause damage to the nervous system and burn tissue in patches along the way. This can leave the victim with symptoms anywhere on the body, and may lead to a complex regional pain syndrome.
