Read the first 7 Signals and Communication Standards flashcards as text

  1. When two signal persons are needed on a job site, how should crane operator instructions be managed?

    Answer: A lead signal person must be designated, and only that person gives signals to the operator

    Only one designated lead signal person may give signals to the crane operator at any given time to prevent conflicting instructions.

  2. What is the correct hand signal for 'Retract Telescoping Boom'?

    Answer: Both fists together, thumbs pointing toward each other, moving hands inward

    Retract telescoping boom is signaled by both fists with thumbs pointing inward, moving the hands toward each other.

  3. If a crane operator loses radio contact with the signal person mid-lift, what is the correct immediate action?

    Answer: Stop all crane movement immediately and re-establish communication before continuing

    Loss of radio communication mid-lift requires an immediate stop of all crane movement until communication is re-established.

  4. What does a signal person indicate when they hold one hand up with all fingers extended and then drop the hand quickly?

    Answer: 'Emergency stop — stop all movement immediately'

    A hand raised with all fingers extended and then rapidly dropped signals Emergency Stop, requiring all crane movement to halt immediately.

  5. Which statement about voice communication via radio for crane operations is correct according to OSHA 1926.1419?

    Answer: Voice commands must use the same terminology as standard hand signals

    OSHA requires that voice commands over radio use the same standard terminology as hand signals to ensure clarity and consistency.

  6. What does the hand signal of pointing index finger held up with a circular wrist rotation indicate?

    Answer: Engage the whip line (auxiliary hoist)

    An index finger pointing up with a circular wrist rotation signals the operator to use the whip line (auxiliary/secondary hoist).

  7. Which condition would legally disqualify a person from acting as a signal person under OSHA 1926.1428?

    Answer: Lacking demonstrated understanding of the signals to be used

    OSHA 1926.1428 requires that a signal person demonstrate understanding of the signals used; failure to demonstrate this disqualifies them.
