1. Which of the following is the most important factor when climbing a
utility pole?
A. Speed
B. Wearing comfortable clothing
C. Proper use of climbing equipment and PPE
D. Pole height
Rationale: Proper use of climbing equipment and personal protective
equipment (PPE) is essential to prevent falls and ensure safety while
working on poles.
2. What is the minimum approach distance to a 7.2 kV energized line
according to OSHA standards?
A. 1 foot
, B. 2 feet 4 inches
C. 3 feet
D. 4 feet
Rationale: OSHA specifies minimum approach distances to prevent
