Path of Current

Amount of Current

• 10 mA can paralyze or “freeze” muscles.

• 75 mA can cause a rapid, ineffective heartbeat -- death will occur in a few minutes unless a defibrillator is used

• 75 mA is not much current (a small power drill uses 30 times as much)

Burns

• Most common shock-related injury

• Occurs when you touch electrical wiring or equipment that is improperly used or maintained

• Typically occurs on hands• Very serious injury that

needs immediate attention

Fall

• Electric shock can also cause indirect injuries

• Workers in elevated locations who experience a shock may fall, resulting in serious injury or death
