A competent person conducting a job hazard analysis identifies a floor hole 2 inches in diameter. What is the OSHA-required protection for this opening?
Answer: A cover capable of supporting twice the intended load
OSHA requires floor hole covers regardless of size, and covers must support twice the maximum intended load of workers and equipment.
Under OSHA's fall protection standards for construction, which activity has a fall protection trigger height of 6 feet?
Answer: Leading edge work
Leading edge work falls under the general construction fall protection trigger of 6 feet per 29 CFR 1926.502.
What distinguishes a 'qualified person' from a 'competent person' in the context of OSHA fall protection?
Answer: A qualified person has recognized degree or professional knowledge; a competent person can identify hazards and has authority to correct them
OSHA defines a qualified person by specialized knowledge/credentials, while a competent person must be able to identify hazards and have authority to take corrective action.
A worker using a body harness notices the back D-ring is located on the small of the back rather than between the shoulder blades. What should the competent person conclude?
Answer: The harness is worn incorrectly and must be adjusted before use
The dorsal D-ring of a full-body harness must be positioned between the shoulder blades for proper fall arrest performance; improper placement requires adjustment before use.
Which of the following correctly describes the 'controlled access zone' (CAZ) method of fall protection?
Answer: A barricaded area accessible only to workers authorized by a competent person, eliminating the need for other fall protection
A CAZ is a work area for leading edge work, precast concrete, or residential construction where access is limited to authorized workers and conventional fall protection may not be required inside the zone.
During fall protection training, workers should be taught that the total fall distance in a PFAS includes which components?
Answer: Free fall distance plus deceleration distance plus the worker's height plus a safety margin
Total fall distance includes free fall, deceleration distance, and the worker's height (D-ring to feet), plus a safety factor to ensure the worker does not contact a lower level.
After a worker's personal fall arrest system has arrested a fall, what is the required action regarding the equipment?
Answer: Remove from service and retire or send to manufacturer for inspection before reuse
OSHA requires that all components of a PFAS that have been subjected to fall arrest forces be immediately removed from service and not reused unless inspected and deemed serviceable by the manufacturer.
