What does the Signals code refer to?

• A. System of verbal communication using the letters of the alphabet only
• B. System of communication that combines numbers and letters of the alphabet, or the combination of some or all of the above to transmit messages
• C. System of communication using numbers followed by the word signal
• D. System of communication by which 10 precedes numbers that stand for specific activities

Answer: (C)

Signals code is a way to send messages quickly and clearly by using numeric codes followed by the word signal. Each number stands for a specific instruction or status, and adding the word signal signals that this is an instruction to be understood and acted on as a signal. This format—numbers plus the word signal—helps reduce ambiguity and speeds up communication in busy or noisy environments, such as coordinating shift actions or safety procedures. The other options describe systems that don’t match this exact pattern: using only letters, combining letters and numbers without the signaling keyword, or a particular rule about the number 10, none of which captures the general structure of numbers followed by the word signal.
