When should primary, spare, and control keys to munitions facilities be inventoried?

Inventorying primary, spare, and control keys to munitions facilities at the end of each shift is crucial for maintaining security and accountability. This practice ensures that all keys are accounted for and that any discrepancies are identified immediately after the shift ends. Regular checks help prevent unauthorized access to munitions and other sensitive areas. By conducting this inventory at the end of each shift, personnel can ensure that keys are returned correctly and that any lost or misplaced keys can be reported and addressed promptly. This procedure enhances the overall security protocol of the facility, allowing for immediate audit trails and accountability at the close of each operational period.
