Construction Fall Protection practice questions for the CHST exam

A concrete crew is tying rebar mats on the face of a vertical wall form. The workers will be about 9 feet above the lower level. The competent person must select protection that complies with the standard. Which choice is compliant?

1. A.Guardrail systems with toeboards only
2. B.Personal fall arrest systems, safety net systems, or positioning device systems
3. C.A controlled access zone with no other fall protection
4. D.A warning line system placed 6 feet from the form face

A drywall crew will work on a flat roof edge with no parapet wall. Guardrails with the top rail 44 inches above the roof surface are already installed. A foreman then has two workers do the edge work on stilts that add 8 inches to their height. The foreman says the 44-inch rails are within the normal range, so no changes are needed. What is the correct determination?

1. A.The guardrail is compliant because 44 inches is within 42 inches plus or minus 3 inches, and stilts do not affect the rule.
2. B.The guardrail is compliant as long as a midrail is installed midway between the top rail and the roof surface.
3. C.The guardrail is not compliant for stilt use; the top edge height must be increased by an amount equal to the height of the stilts.
4. D.The guardrail is not compliant because any top rail above 42 inches must be lowered to exactly 42 inches when stilts are used.

On an elevated slab, a crew covers a floor hole with a sheet of plywood. The hole is in an interior work area where only workers and a small hand-propelled material cart travel. No vehicles use the area. A foreman inspects the cover and finds that it is strong enough to carry well over twice the combined weight of the workers, cart, and materials that could be on it at once. The cover sits loosely in place over the hole and is marked with the word "HOLE." Which statement best describes the cover's compliance?

1. A.It is compliant, because strength at twice the expected load plus the "HOLE" marking satisfies the cover requirements.
2. B.It is not compliant, because covers must be capable of supporting twice the maximum axle load of the largest vehicle expected, regardless of location.
3. C.It is not compliant, because covers must be color coded rather than marked with the word "HOLE" or "COVER."
4. D.It is not compliant, because the cover is not secured against accidental displacement by wind, equipment, or employees when installed.
