The degree of electricity-induced injury is dependent on the following:
- AMOUNT: This refers to the amount of electrical energy that is delivered. The risk of severe injury increases when there is contact with a higher electrical voltage or current.
- RESISTANCE: The resistance encountered will vary, depending on where the electrical current passes through the body.
- TYPE: There are two types of current, known as alternating current (AC) and direct current (DC).
- PATHWAY: There are certain tissues/body sites that, if located in the pathway of the current, will greatly increase the severity of the injury received.
- DURATION: The risk of severe injury is greater the longer the length of time the body remains in contact with the electrical current.
