What action should be taken if the timer knob of a LUU-2/B flare is accidentally pulled during ground handling?

When the timer knob of a LUU-2/B flare is accidentally pulled during ground handling, the appropriate course of action is to hold the mechanism to prevent ejection and secure it with tape. This is crucial because pulling the timer can activate the flare, creating a potentially hazardous situation. By holding the mechanism, you are directly preventing any unintended ignition or ejection that could occur if the device is not secured. Taping it ensures that this action remains effective until the flare can be safely managed or disposed of following the appropriate protocols.

This response prioritizes safety and controls the situation effectively, preventing further risk or injury that could arise from a flare in an active state. Proper handling methods and safety protocols in munitions management are essential to maintain safety during operations.
