Read the first 7 Rigging Fundamentals & Material Handling flashcards as text

  1. What hand signal is used to instruct a crane operator to raise the load?

    Answer: Finger pointing up with a circular motion of the forearm and hand

    The ASME-standard 'hoist' signal is made by pointing the index finger upward and rotating the forearm and hand in a circle to indicate raising the load.

  2. What is the correct action when you discover defective rigging equipment on a job site?

    Answer: Tag it out and remove it from service immediately

    Defective rigging equipment must be immediately tagged out and removed from service to prevent use that could cause equipment failure and serious injury.

  3. What is 'blocking' or 'cribbing' used for in material handling and rigging?

    Answer: Supporting and stabilizing loads when they are set down

    Blocking or cribbing consists of wood or composite materials placed under a lowered load to support it stably and allow rigging to be removed safely.

  4. OSHA standards require that workers remain outside the swing radius of a crane's counterweight to prevent:

    Answer: Being struck by the rotating counterweight

    The rotating counterweight on a crane can strike and kill workers who enter its swing radius, making it a recognized crush and strike hazard zone.

  5. When stacking materials on a job site, the general rule for maximum stack height is based on:

    Answer: The stability and weight of the material to prevent tipping

    Material stacking height is limited by the stability and weight characteristics of the materials to ensure stacks do not tip over, which could injure workers.

  6. What is the primary reason to never stand or walk under a suspended load?

    Answer: Rigging failure or dropped load can cause fatal crush injuries

    Standing under a suspended load is prohibited because a rigging failure or dropped load can result in catastrophic and fatal crush injuries.

  7. When manually lifting a heavy object, which technique best protects the worker's back?

    Answer: Position the load close to the body, bend the knees, and lift with the leg muscles

    Keeping the load close, bending the knees, and using the stronger leg muscles reduces spinal stress and is the accepted technique for safe manual lifting.
