Final answer:
The three types of burns caused by exposure to electricity are electrical burns, arc burns, and flash burns.
Step-by-step explanation:
Electricity presents two known hazards: thermal and shock. A thermal hazard is one in which an excessive electric current causes undesired thermal effects, such as starting a fire in the wall of a house. A shock hazard occurs when an electric current passes through a person. Shocks range in severity from painful, but otherwise harmless, to heart-stopping lethality.
In terms of burns caused by exposure to electricity, there are three types: electrical burns, arc burns, and flash burns.
- Electrical burns: These burns occur when electric current passes through the body, causing damage to internal organs. The entry and exit points of the current may result in deep, tissue-damaging burns.
- Arc burns: Arc burns are caused by an electric arc, which is a discharge of electric current that jumps across a gap between conductors. These burns can be caused by an electrical explosion or contact with high-voltage equipment.
- Flash burns: Flash burns are caused by an intense burst of heat and light generated by an electrical explosion. These burns often affect the face and hands.
