  1. Under OSHA 1926.1412, what must a crane operator do before beginning any lifting operations?

    Answer: Conduct a pre-shift visual inspection of the crane, including controls, safety devices, wire rope, and operational aids

    OSHA 1926.1412(d) requires the operator to conduct a visual inspection of the crane at the beginning of each shift to check all systems, controls, wire ropes, hooks, and safety devices before any lifting operations begin.

  2. What is the required minimum clearance between a crane and an energized power line rated between 50 kV and 200 kV under OSHA 1926.1408?

    Answer: 15 feet

    For power lines rated over 50 kV up to 200 kV, OSHA 1926.1408 Table A requires a minimum clearance of 15 feet between any part of the crane (including load line and load) and the energized line.

  3. What does a crane's 'load chart' specify, and why must it be accessible to the operator at all times?

    Answer: The maximum loads the crane can safely lift at various radii, boom lengths, and configurations — it must be accessible so the operator can verify any proposed lift is within rated capacity

    A crane load chart provides the rated capacity for the crane at varying radii, boom lengths, boom angles, and configurations, allowing the operator to determine whether a proposed lift is within the crane's safe working load.

  4. Under OSHA 1926.1425, when are tag lines required during crane lift operations?

    Answer: When the load must be controlled to prevent rotation, swinging, or uncontrolled movement that could endanger workers

    Tag lines are required when the load might rotate, swing, or otherwise move in an uncontrolled manner that could endanger employees — not based on a fixed weight or height threshold.

  5. What does OSHA 1926.1412 prohibit regarding crane rated capacity during normal lifting operations?

    Answer: Operating a crane in excess of its rated capacity under any normal operational conditions

    OSHA 1926.1412(a) states that cranes must not be loaded beyond their rated capacity. The only exception is during manufacturer-approved load testing performed per the manufacturer's procedures.

  6. Under OSHA 1926.1404, which of the following is a recognized pathway for crane operator qualification?

    Answer: Certification by an accredited crane operator testing organization such as NCCCO

    OSHA 1926.1404(a) requires crane operators to be certified by an accredited testing organization (such as NCCCO), licensed by a state or local government, or qualified through an employer's qualifying program meeting OSHA criteria.
