Which class of hard hat provides protection against electrical hazards up to 20,000 volts and is recommended for aerial lift operators working near overhead power lines?

Accepted Answer

Class B

Answer

Class B hard hats are rated to protect against electrical hazards up to 20,000 volts (phase-to-ground) and are appropriate for work near energized lines.

Question 2

How frequently must fall protection equipment be formally inspected by a competent person, in addition to the operator's pre-use check?

Accepted Answer

At least annually

Answer

ANSI Z359.2 and OSHA guidance require a competent person to conduct a formal inspection of all fall protection equipment at least once a year.

Question 3

An operator discovers a hairline crack in the shell of their hard hat during a pre-use inspection. What is the correct action?

Any crack, dent, or penetration in a hard hat shell compromises its structural integrity and requires immediate removal from service.

Question 4

When working in aerial lifts near energized electrical components, which type of gloves should an operator select?

Accepted Answer

Rubber insulating gloves rated for the voltage level present

Answer

Rubber insulating gloves (dielectric gloves) rated to the voltage level present are required for protection against electrical shock when working near energized parts.

Question 5

What is the primary purpose of a shock-absorbing (deceleration) lanyard?

Accepted Answer

To reduce the peak arrest force transmitted to the worker's body during a fall
