Question 1

What is the minimum approach distance (MAD) for a qualified lineman working on 15 kV lines without insulated tools?

Accepted Answer

2 feet 2 inches

Answer

OSHA Table R-6 specifies a minimum approach distance of 2 feet 2 inches for voltages between 15.1 and 17.5 kV.

Question 2

When performing CPR on an adult victim, what is the correct compression-to-ventilation ratio for a single rescuer?

Accepted Answer

30:2

Answer

Current American Heart Association guidelines specify a 30:2 compression-to-ventilation ratio for single-rescuer adult CPR.

Question 3

What type of glove must be worn when working on energized electrical conductors rated above 750 volts?

Accepted Answer

Rubber insulating gloves of the appropriate voltage class

Answer

OSHA 1910.137 requires rubber insulating gloves rated for the specific voltage class of the work being performed.

Question 4

A lineman is asked to work in an excavation that is 6 feet deep in Type C soil. What is required before entry?

Accepted Answer

Answer

OSHA 1926.652 requires excavations 5 feet or deeper in Type C soil to be protected by shoring, sloping to 1.5:1, or a trench box.

Question 5

What does the term 'equipotential zone' mean in lineman safety?

Accepted Answer

An area where all conductive objects are bonded to the same electrical potential

Answer

An equipotential zone bonds all conductive surfaces so no dangerous voltage difference exists between them, protecting workers from step and touch potential hazards.
