NSC Fall Protection 5

Question 1

What is the maximum gap allowed between a safety net and the work surface it protects below according to OSHA?

Accepted Answer

Answer

OSHA requires safety nets to be installed as close as practicable below the work surface and no more than 30 feet below it.

Question 2

A horizontal lifeline system must be designed by a qualified person and should have a safety factor of at least:

Accepted Answer

2

Answer

OSHA requires horizontal lifeline systems to be designed, installed, and used under the supervision of a qualified person with a minimum safety factor of 2.

Question 3

Which leading edge work scenario triggers OSHA's requirement for fall protection in construction at 6 feet?

Accepted Answer

Working near an unprotected leading edge where the surface is being constructed

Answer

Leading edge work involves advancing the working surface (e.g., decking installation), and OSHA requires fall protection when that edge is 6 feet or more above a lower level.

Question 4

Per NSC recommendations, what is the first step in a fall protection hierarchy before selecting equipment?

Accepted Answer

Eliminate the fall hazard entirely

Answer

The hierarchy of controls places hazard elimination first — redesigning tasks or structures so the fall hazard no longer exists — before any protective measures.

Question 5

Which type of anchorage must be used when a single worker is attached and requires the anchorage to support fall arrest forces?

Accepted Answer

An anchorage capable of supporting 5,000 lbs per attached worker

Answer

OSHA requires fall arrest anchorages to support at least 5,000 pounds per worker attached, or be designed with a safety factor of 2 by a qualified engineer.
