What is arc flash? Arc flash is the visual electrical light and heat that occur during an arc fault
What's the minimum voltage at which serious electric 50 volts
shock can occur?
What determines the severity of injury in arc flash? The available current and duration of the arc flash
What injuries are associated with electric shock? A. Electrocution
B. Suffocation
C. Tissue and organ damage
D. All of the above - Correct Answer
How are arc flash and electric shock protection Qualified workers use NFPA 70E boundary tables or the employer's safe work
boundaries determined? practices tables to determine arc flash and shock protection boundaries.
What is an arc flash protection boundary? The distance from energized equipment at which a worker, unprotected by
proper PPE, would sustain burns less than those from a mild sunburn
What constitutes an "electrically safe condition"? Equipment is locked and tagged in a de-energized position and then tested to
ensure there is no stored or protentional energy
Who can enter limited and restricted boundaries? Electrically-qualified workers and those undergoing on-the-job training with
demonstrated ability to safely perform the required task
