| How Electrical Shock Happens |
Electrical current travels along circuits of wires. A circuit is a closed loop that allows electricity to flow. Electrical shock occurs when a person’s body contacts an electrical circuit and provides a path for electricity to leave the circuit and travel to the ground. On the job site, this can happen when: |
| • |
You contact one wire of an energized circuit and the ground at the same time.
|
|
| • |
You touch equipment that’s in contact with an energized wire while you’re also in contact with the ground.
|
|
|
| What Happens When You Get Shocked? |
Lower voltages (and lower amperages) can cause muscle spasms that inhibit your ability to “let go” of the energized object you’re touching. The degree of injury increases with every second your body is conducting electricity. |
Higher voltages (and higher amperages) can throw you clear of the circuit; however, injury or death may result from the electrical shock or fall. |
| Keep Your Distance |
Distance is your best defense against electrical shock. Always keep yourself, your tools and your equipment far away from power lines and electrical components. |
