Within how many hours must transactions for security risk category I and II items be completed?

Transactions for security risk category I and II items must be completed within 24 hours to ensure compliance with regulations concerning the storage, handling, and accountability of these sensitive materials. This timeframe is established to maintain a high level of security and control over potentially hazardous explosives and related items, mitigating the risks associated with their management on board an aircraft carrier. The 24-hour window allows for timely processing and oversight, which is critical in an environment where safety is paramount and rapid response is often necessary. This requirement reflects an understanding that swift action is essential to address potential security issues or inventory discrepancies.
