OSHA Crane Regulations 29 CFR 1926 Flashcards

Under 29 CFR 1926.1416, when an equipment deficiency is identified that does not meet the 'remove from service' criteria but still affects safe operation, what is the OSHA-required course of action?

Answer: The deficiency must be corrected before the equipment is used again unless the employer can demonstrate that the deficiency does not affect safe operation

Under 29 CFR 1926.1416(d)(2), if a deficiency is identified that does not meet the criteria for immediately removing equipment from service, the employer must ensure the deficiency is corrected before using the equipment, unless the employer can demonstrate that correcting the deficiency is not necessary for the equipment to be operated safely. Simply reducing capacity or getting operator agreement is not a compliant alternative.

A crane operator holds a valid NCCCO certification for a Lattice Boom Crawler crane. Under 29 CFR 1926.1427, which of the following tasks would NOT be permitted without additional qualification?

Answer: Operating a hydraulic telescoping boom truck crane of equivalent capacity on the same jobsite

Under 29 CFR 1926.1427, operator certification is crane-type specific. A certification for a Lattice Boom Crawler does not automatically authorize operation of a Hydraulic Telescoping Boom Truck Crane — these are separate crane types requiring separate certification. Capacity differences within the same crane type are generally covered, and functional tests and rigging assistance do not require operator certification.

Under 29 CFR 1926.1408, an existing power line is presumed to be energized at what voltage when the utility owner/operator cannot be reached to confirm the line's status?

Answer: The line must be treated as if it carries the maximum voltage shown in Table A (350 kV or above)

Per 29 CFR 1926.1408(a)(1), when the utility owner/operator cannot be contacted to determine the voltage of a power line, the employer must treat the line as if it is energized at the highest voltage level shown in Table A — effectively 350 kV or above — requiring the maximum clearance distance of 20 feet. This is a deliberately conservative default to maximize worker safety.

Under 29 CFR 1926.1415, the pre-shift inspection requirement applies to which of the following scenarios?

Answer: Each day the equipment is used, regardless of whether it was inspected the previous shift

Under 29 CFR 1926.1415(a), the pre-shift inspection must be conducted each day before the equipment is used. This requirement is not waived based on who operated the crane previously, whether it was inspected recently, or where it is located. The daily frequency is absolute — every shift of use requires its own inspection.

A signal person is being used on a construction site under 29 CFR 1926.1419. The crane operator loses sight of the signal person mid-lift due to an obstruction. Under OSHA regulations, the operator must:

Answer: Stop all crane movement and remain stopped until communication with the signal person is re-established or a new signal person with line-of-sight is designated

Under 29 CFR 1926.1419(b), when the operator loses sight of the signal person, the operator must stop all crane movement. Movement may only resume when the signal person is again visible to the operator, or a new signal person with clear line-of-sight is in position. Proceeding at reduced speed, using relayed signals, or switching to radio without stopping first are all non-compliant responses.

Under 29 CFR 1926.1412, after a crane has been involved in an accident or a near-miss involving a significant loss of structural integrity or unexpected free fall, what is the required sequence before it may be returned to service?

Answer: The equipment must be inspected by a qualified person, and any deficiencies identified must be corrected before the equipment is returned to service

Under 29 CFR 1926.1412(f), after a crane is involved in an accident or near-miss involving a significant loss of structural integrity or an unexpected free fall, the equipment must be inspected by a qualified person prior to being returned to service, and all identified deficiencies must be corrected before resumption of use. OSHA does not require manufacturer authorization or OSHA Area Director clearance as preconditions — the qualified person inspection and deficiency correction are the controlling requirements.
