1. Which of the following parameters does not play a role An outdoors application
in the severity of current passing through the human
body?
2. Which of the following best describes the primary To reduce severity of
purpose of overcurrent protective devices (OCDs) con- arc-flash events
cerning arc-flash and arc-blast hazards?
3. Energized electrical conductors and circuit parts oper- 50v
ating at voltages equal to or greater than ? shall be
put into an electrically safe work condition before an
employee performs work if any of the two stated con-
ditions exist. An exception to this requirement states
that energized work shall be permitted where the em-
ployer can demonstrate that de-energizing introduces
additional hazards or increased risk.
4. Which of the following is the electrical shock voltage 50 VAC / 50 VDC
threshold?
5. In the context of incident energy, why is regular main- To minimize the risk of arc

ed injuries
6. An are energy reduction system impacts safety Reduces severity of an arc

on and the arcing current
is in the operating region
7. What role does regular maintenance play in prevent- It identifies and rectifies
