NCCCO - National Commission for the Certification of Crane Operators OSHA Crane Regulations 29 CFR 1 — Questions and Answers
Question 1: Under OSHA 29 CFR 1926.1416, how frequently must the crane operator perform a visual inspection of the equipment before beginning work?
- Once per week, at the start of each work week
- Before each shift (Correct answer)
- Once per month, documented in a logbook
- Before every individual lift
Correct answer: Before each shift
29 CFR 1926.1416(d)(1) requires the operator to perform a visual inspection before each shift to identify any visible defects or conditions that could create a hazard. This ensures equipment integrity is confirmed at the start of every work period.
Question 2: Under OSHA 29 CFR 1926.1431, what percentage of a personnel platform's rated capacity must be used as the proof test load before hoisting personnel?
- 100%
- 110%
- 125% (Correct answer)
- 150%
Correct answer: 125%
29 CFR 1926.1431(f)(1) requires proof testing at 125% of the personnel platform's rated capacity using test weights prior to hoisting personnel. This overload test verifies that sufficient safety margin exists before workers are placed in the platform.
Question 3: Under OSHA 29 CFR 1926.1415, which safety device is required on ALL equipment covered by Subpart CC to prevent the hook block from contacting the boom tip?
- Load moment indicator (LMI)
- Anti-two-block device (Correct answer)
- Boom angle indicator
- Rated capacity limiter
Correct answer: Anti-two-block device
29 CFR 1926.1415(a)(1) mandates an anti-two-block device on all covered equipment. Two-blocking occurs when the hook block contacts the boom tip or sheave, which can cause the load line to part and drop the load. This device prevents that condition.
Question 4: Under OSHA 29 CFR 1926.1404, who is required to direct crane assembly and disassembly (A/D) operations?
- The crane operator assigned to the equipment
- A competent person designated by the employer
- A qualified person serving as A/D director (Correct answer)
- The general contractor's site superintendent
Correct answer: A qualified person serving as A/D director
29 CFR 1926.1404(a) requires that assembly and disassembly operations be directed by a qualified person acting as the A/D director. A qualified person has the specialized knowledge and training to recognize and address hazards specific to assembly and disassembly.
Question 5: Under OSHA 29 CFR 1926.1412, how frequently must a comprehensive inspection of covered crane equipment be conducted by a qualified person?
- Every 6 months
- Every 12 months (Correct answer)
- Every 24 months
- Every 3 years
Correct answer: Every 12 months
29 CFR 1926.1412(f)(1) requires a comprehensive inspection at intervals not exceeding 12 months. This inspection covers all components not examined in more frequent inspections and must be performed by a qualified person, with findings documented.
Question 6: Under OSHA 29 CFR 1926.1417, what action must a crane operator take if continuing a lift would exceed the equipment's rated capacity?
- Proceed at a reduced hoisting speed to minimize dynamic loading
- Obtain verbal authorization from the site safety officer before continuing
- Stop the operation and refuse to proceed until the concern is resolved (Correct answer)
- Reduce the boom radius to compensate for the excess load weight
Correct answer: Stop the operation and refuse to proceed until the concern is resolved
29 CFR 1926.1417(b) gives operators the authority and responsibility to stop operations when a safety concern arises, including when the rated capacity would be exceeded. Operators must not proceed until the issue is corrected — exceeding rated capacity is never permissible.
