What is the consequence of not removing ordnance after 108 hours in an operating building?

The correct choice highlights the critical safety considerations associated with munitions handling and storage. Failure to remove ordnance after a specified period, such as 108 hours, significantly elevates the risk of accidents. This is particularly due to the potential for mishandling or deterioration of the ordnance in an operational environment, which may not be adequately designed for long-term storage.

Extended periods of storage in such environments may lead to unforeseen complications, including but not limited to the degradation of the ordnance's condition and the increased possibility of accidents involving explosions or other safety hazards. Recognizing that safety is paramount in munitions operations, protocols are in place to mitigate these risks, which include timely removal of ordnance from active areas. This decision directly ties into overall workplace safety and the prevention of incidents that could result in injury or damage to personnel and property.

Contextually, while equipment failure, legal penalties, and higher maintenance costs are relevant to ordnance management, the immediate and direct consequence of not adhering to proper storage durations relates most closely to the increased risk of accidents.
