NCCCO Hand Signals & Communication Protocols 5

Question 1

In low-visibility or noisy environments where hand signals and radio are both impractical, what backup communication method is NCCCO-recognized?

Accepted Answer

Using a pre-agreed whistle or air horn code

Answer

NCCCO and ASME B30.5 recognize audible signals (horn or whistle codes) as an acceptable backup when standard methods are impractical.

Question 2

What is the correct hand signal for 'Extend Boom' (telescoping)?

Accepted Answer

Both fists together, thumbs pointing outward

Answer

To signal 'Extend Boom,' both fists are held together with thumbs pointing outward, mimicking the boom telescoping out.

Question 3

A newly assigned signalperson arrives on a job site. Before they direct any crane operation, what NCCCO requirement must be met?

Accepted Answer

They must be verified as qualified and acknowledged by the operator before work begins

Answer

NCCCO and OSHA require the signalperson to be qualified (trained and evaluated) and the crane operator must acknowledge them before any signals are given.

Question 4

During a pick-and-carry operation, who has primary authority over travel direction signals?

Accepted Answer

The appointed signalperson designated before the operation began

Answer

Only the pre-designated signalperson has authority to direct the operator during pick-and-carry; random workers along the path cannot override this.

Question 5

What does it mean when a signalperson taps the top of their helmet with an open palm?

Accepted Answer

This is a crane operator signal only — not a standard ASME hand signal

Answer

Tapping the helmet is not an ASME B30.5 standardized hand signal; only the defined set of signals should be used to avoid misinterpretation.
