Which of the following is a complete set of four communication methods you can use on site?

• A. Verbal
• B. Verbal, Written, Signs, Hand Signals
• C. Signs and Hand Signals
• D. Verbal, Signs, and Written

Answer: (B)

On-site safety relies on multiple ways to communicate so messages get through in different situations. The complete set includes verbal, written, signs, and hand signals. Verbal helps give immediate instructions, but noise or distance can hide speech. Written communication provides formal instructions and records. Signs offer constant, visible warnings and directions, visible regardless of who’s speaking. Hand signals are essential when you can’t rely on voice, such as when a forklift is moving and signaling from a distance or around noise.

So the four-method set—verbal, written, signs, and hand signals—covers real-time talk, documented guidance, visible warnings, and non-verbal direction. The other options miss one of these methods, so they aren’t a complete set.
