How many standard hand signals are listed for directing the Aerial?

• A. 3
• B. 5
• C. 4
• D. 6

Answer: (C)

Clear, standardized hand signals are essential for coordinating aerial operations. There are four fundamental signals that cover the two ways the boom moves: vertically and horizontally. Directing the Aerial uses signals for raising the ladder, lowering the ladder, extending the boom, and retracting the boom. These four commands let the ground guide communicate precisely what the operator should do, reducing the chance of miscommunication in stressful, time-critical situations. If fewer than four signals were used, one essential movement wouldn’t have a clear directive, while more than four would complicate coordination and slow responses.
