What this covers

Sample questions

Apart from an emergency stop, how many people should be signalling an operator at one time?

  1. Any two workers who agree
  2. Every worker near the machine
  3. One designated signal person
  4. One person on each side
Show the answer

C. One designated signal person

Signals from more than one person conflict and confuse, so a single designated signal person directs the machine. The only exception is a stop signal, which anyone can give.

Reference: NCCER Heavy Equipment Operations Level 1, Heavy Equipment Safety

What must an operator and a signal person do before starting work together?

  1. Agree on the signals that will be used
  2. Exchange phone numbers for texting each other
  3. Trade places to learn both jobs
  4. Sign the daily equipment log
Show the answer

A. Agree on the signals that will be used

Signals vary between crews and machines, so both people confirm the set of signals before the machine moves. A signal that means different things to each person is as dangerous as no signal.

Reference: NCCER Heavy Equipment Operations Level 1, Heavy Equipment Safety

Which describes the standard hand signal for an emergency stop?

  1. One arm straight up with the fist closed and held still
  2. Both hands clasped together in front of the body
  3. Both arms out to the sides, palms down, swung back and forth
  4. One forearm raised with the index finger circling above the head
Show the answer

C. Both arms out to the sides, palms down, swung back and forth

The emergency stop uses both arms extended horizontally with palms down, waved back and forth. Clasped hands is the signal to dog everything (hold all functions), and a circling raised finger means hoist.

Reference: 29 CFR 1926 Subpart CC, Appendix A (standard hand signals)
