What is the first indication that munitions items may not be safe?

The first indication that munitions items may not be safe is damaged seals. Seals are critical for maintaining the integrity and safety of munitions. They protect the contents from environmental factors such as moisture and contaminants that could lead to deterioration or unsafe conditions. When seals are damaged, it raises immediate concerns about the condition of the item inside and whether it remains safe for use.

While rust on the exterior, defective markings, and improper storage can also signal potential issues with munitions safety, they are secondary indicators. Rust may not affect the functionality immediately, defective markings can often be rectified or corrected, and improper storage might indicate a lack of care but does not guarantee immediate safety risks. In contrast, damaged seals signify a direct compromise, suggesting that the contents may have been exposed to harmful conditions, making them the primary concern for safety.
