Safety Procedures & PPE Flashcards

What is the purpose of a 'hot stick' (live-line tool) when working on energized lines?

Answer: To maintain safe working distance between the worker and energized parts

Hot sticks provide insulation and safe reach distance, allowing workers to operate energized equipment without direct contact.

PPE Category 4 (formerly HRC 4) requires arc-rated clothing and equipment with a minimum arc rating of 40 cal/cm².

When using personal protective grounds at AEP, the ground should be attached in which order?

Answer: Ground end first, then hot end

Grounding procedure requires connecting the ground end first to provide a fault current path before the hot end is connected to the conductor.

What hazard does FR (flame-resistant) clothing protect against that standard PPE does not?

Answer: Arc flash and flash fire thermal hazards

FR clothing is designed to self-extinguish and resist ignition, protecting workers from burns caused by arc flash and flash fire events.

What does a 'two-call' or 'two-challenge' rule require in AEP safety culture?

Answer: A worker must speak up twice if a safety concern is not addressed

The two-challenge rule requires a worker to raise a safety concern at least twice to ensure it is heard and addressed before proceeding.

Which atmospheric hazard is most commonly tested for before entering electrical manholes or vaults?
