Question 1

Which knot is most commonly recommended for securing a safety rope to an anchor during roof sailing operations?

Accepted Answer

Bowline knot

Answer

The bowline knot creates a secure, non-slipping loop that is easy to untie after loading, making it the preferred choice for life-safety rope anchoring.

Question 2

A roofer notices that the existing decking has soft spots. What is the safest course of action?

Accepted Answer

Stop work and replace the damaged decking before proceeding

Answer

Soft spots indicate rotted or structurally compromised decking, which poses a fall-through risk and must be replaced before any work continues.

Question 3

When is a personal fall arrest system (PFAS) required on a residential roof?

Accepted Answer

Whenever a worker is at a height of 6 feet or more above a lower level

Answer

OSHA 1926.502 mandates a PFAS or other fall protection when any worker is exposed to a fall of 6 feet or more on a residential construction site.

Question 4

What is the maximum free-fall distance allowed by OSHA when using a personal fall arrest system?

Accepted Answer

6 feet

Answer

OSHA requires that a PFAS limit free-fall to no more than 6 feet and arrest a fall before the worker contacts a lower level.

Question 5

Which roofing material requires the steepest minimum pitch to prevent water infiltration?

Accepted Answer

Wood shingles

Answer

Wood shingles typically require a minimum pitch of 3:12 to 4:12 because they rely on rapid water runoff and do not seal as tightly as other materials.
