Question 1

Under OSHA 29 CFR 1926, what is the maximum free-fall distance allowed when using a personal fall arrest system?

Accepted Answer

6 feet

Answer

OSHA limits free fall to 6 feet when using a personal fall arrest system on construction sites.

Question 2

A worker is installing roofing on a low-slope roof with a 4:12 pitch. What fall protection method is acceptable under OSHA 1926.502?

Accepted Answer

Guardrail, safety net, or personal fall arrest system

Answer

On low-slope roofs, OSHA requires conventional fall protection (guardrails, safety nets, or PFAS) or a warning line system combined with other measures.

Question 3

What is the minimum breaking strength required for a safety net used as fall protection under OSHA standards?

Accepted Answer

2,500 pounds

Answer

OSHA 1926.502(c) requires safety nets to have a minimum breaking strength of 5,000 pounds — but the mesh must withstand a 400-pound drop test; nets must meet specific installation and drop-test criteria.

Question 4

When must debris and tools that fall into a safety net be removed?

Accepted Answer

Within 24 hours of falling into the net

Answer

OSHA 1926.502(c)(15) requires that materials, scrap, and equipment that fall into safety nets be removed as soon as possible, and at least before the next work shift.

Question 5

A supervisor notices a snap hook on a worker's lanyard is connected to another snap hook (gate-to-gate). What is the hazard?

Accepted Answer

Roll-out can cause accidental disengagement under load

Answer

Connecting snap hook to snap hook (or other connectors not designed for it) creates roll-out risk, where the gate can open and disengage under a side-loading force.
