Being hit by high voltage may cause skin damage, disability and death and other hazards, but the specific damage needs to be judged according to the degree of high voltage electric shock. 1. skin damage: when the human body is high-voltage electric shock, if the contact time is relatively short and the current is relatively low, only part of the limb burns, resulting in skin damage, but can not be completely excluded from the visceral damage, need to carry out the relevant examination, and in 72 hours after the re-examination, and to clarify the damage to the body in a timely manner and to take targeted intervention measures. 2. Disability: If the current of the high voltage electric shock is relatively large, and some of the limbs of the patient have more serious burns, it may need to be amputated, resulting in lifelong disability. 3. death: some people may suffer cardiac arrest after being shocked by high voltage electricity, which may seriously affect the safety of life. High-voltage electricity on the human body is more harmful, must be careful attention, in the necessary circumstances need to do a good job of safety measures, if subjected to high-voltage electric shock should be carried out in a timely manner after a comprehensive examination to minimize the damage to the body to avoid causing serious impact.
