What is the primary purpose of an Energized Electrical Work Permit (EEWP)?
Answer: To document justification, hazard analysis, and PPE requirements when energized work is unavoidable
An EEWP formally documents why energized work cannot be avoided, identifies the arc flash hazard level, and specifies the PPE and procedures required.
When using voltage-rated gloves for electrical work, what additional protection must always be worn over them?
Answer: Leather protector gloves
Leather protector gloves must be worn over rubber insulating gloves to protect the rubber from punctures, cuts, and abrasions that would compromise their insulating properties.
A qualified electrician is about to verify that a circuit is de-energized. In what order should the steps be performed?
Answer: Test the meter on a known live source, test the suspect circuit, test the meter on a live source again
The test-before-touch procedure requires verifying meter functionality on a known live source both before and after testing the de-energized circuit to confirm the meter is working correctly.
Under OSHA standards, what minimum approach distance applies to unqualified workers near overhead power lines operating at 50 kV or below?
Answer: 10 feet
OSHA 29 CFR 1926.1408 requires unqualified workers to maintain a minimum 10-foot clearance from overhead power lines operating at 50 kV or below.
Which action is prohibited when using portable ladders near energized electrical equipment?
Answer: Using metal or conductive ladders within the limited approach boundary
Conductive (metal) ladders must never be used near energized electrical equipment because they create a path for electrical current to flow through the worker.
What does 'arc flash boundary' specifically define?
Answer: The distance at which a person could receive a second-degree burn from an arc flash incident
The arc flash boundary is the distance from an arc source at which an unprotected person could receive a second-degree burn (1.2 cal/cm²) from incident energy.
A contractor is working on equipment with multiple energy sources including electrical, pneumatic, and hydraulic. Which LOTO procedure applies?
Answer: A complex (multi-energy) lockout procedure addressing all energy sources
When equipment has multiple energy sources, a complex lockout procedure must identify, isolate, and lock out every energy source—electrical, pneumatic, hydraulic, thermal, gravity, and stored energy.
