AEP Tools & Equipment Operation 3

Question 1

When operating a digger derrick near overhead energized lines, the minimum approach distance for the boom must comply with which standard?

Accepted Answer

OSHA 29 CFR 1926.1408 and NESC approach tables

Answer

OSHA 1926.1408 governs crane/derrick operations near power lines and references NESC minimum approach distances for qualified workers.

Question 2

A strap wrench is preferred over a pipe wrench when working on certain transformer bushings because it:

Accepted Answer

Grips without leaving jaw marks on porcelain or polished fittings

Answer

A strap wrench's fabric strap distributes force evenly, preventing damage to porcelain bushings or chrome-plated fittings that pipe jaws would scar.

Question 3

Before using a chain saw for vegetation management on a right-of-way, AEP safety procedures require the operator to:

Accepted Answer

Inspect the chain tension, bar lubrication, and all safety guards

Answer

Pre-use inspection of chain tension, bar oil level, and operational guards ensures the saw functions safely and reduces kickback risk.

Question 4

What type of fire extinguisher is approved for use on energized electrical equipment at an AEP substation?

Accepted Answer

Class B CO2 or dry chemical (Class C rated)

Answer

Class C ratings on CO2 or dry chemical extinguishers indicate the agent is non-conductive and safe for energized electrical fires.

Question 5

A cable puller's tension gauge reads 8,000 lbs while pulling a cable rated for 5,000 lbs maximum pulling tension. The lineman should:

Accepted Answer

Stop immediately, release tension, and reassess the pull setup
