What is indicated if the rocket motor's arm/fire device (AFD) is in the safe condition?

When the rocket motor's arm/fire device (AFD) is in the safe condition, it is indicated by a white "S" on a green background. This signaling system helps ensure that everyone is aware of the status of the arm/fire device, which is critical for safety during munitions handling. The use of a specific color and symbol—white "S" on green—provides clear communication that the device is in a safe state, minimizing risk and potential hazards in a munitions environment.

In the context of munitions operations, proper identification and understanding of safety signals are paramount, as they play a vital role in maintaining safe practices during munitions handling and prevention of accidental activation.
