Burns and Other Injuries
| Shock-related injuries include burns, internal injuries, and injuries due to involuntary muscle
contractions. |
Burns
The most common shock-related injury is a burn. Burns suffered in electrical incidents may be one or
more of the following three types:
- Electrical burns cause tissue damage, and are the result of heat generated by the flow of electric current through
the body. Electrical burns are one of the most serious injuries you can receive and should be given immediate
attention.

- High temperatures near the body produced by an electric arc or explosion cause
arc or flash burns. They should also
be attended to promptly.

- Thermal contact burns occur when skin comes in contact with overheated electric equipment, or when clothing is
ignited in an electrical incident.

Internal Injuries
|
Excessive electricity flowing through the human body can cause serious damage to internal organs.
Resulting medical problems include hemorrhage (or internal bleeding), tissue destruction, and nerve or muscle damage.
These internal injuries may not be immediately apparent to the victim or observers; however, left untreated, they can
result in death.

Involuntary Muscle Contraction
|
Normal muscle contraction is caused by very small amounts of electricity that are created within our bodies. Muscles
violently contract when stimulated by excessive amounts of electricity. These involuntary contractions can damage
muscles, tendons, and ligaments, and may even cause broken bones. If the victim is holding an electrocuting object, hand
muscles may contract, making it impossible to drop the object and prolonging contact with the current. Also, injury or
death may result when violent muscle contractions cause workers to fall from ladders and scaffolds or inadvertently
strike other objects. |
