What does the signal 'Close up/open up or extend' look like?

• A. Both arms extended laterally bringing toward midline, hands together and opening up all the way
• B. Extend one arm overhead, wave hand and arm front, left, right, rear
• C. Palm to the front, thrust hand upward and extend and hold until understood
• D. Make a fist with hand and do not move

Answer: (B)

Extending a single arm overhead and waving it toward the front, then left, right, and rear is how you signal to “open up” or “extend.” The raised arm gives a clear, high-visibility cue, and sweeping it in all directions shows the action applies in every direction, so everyone nearby can understand the intent even from different angles or distances. The other motions either imply closing up (pulling arms toward the midline), are just an upward thrust without indicating extension, or are a static fist, which don’t communicate extending/opening.
