What term is used to clearly indicate previously opened hermetically sealed containers?

The term utilized to clearly indicate previously opened hermetically sealed containers is "Not Hermetically Sealed." This terminology is essential because it communicates a critical condition of the container that affects the safety and usability of its contents. Hermetically sealed containers are designed to maintain an airtight environment, protecting the contents from moisture, air, and contaminants. If a container has been opened, it is no longer hermetically sealed, and acknowledging this change in status is vital for inventory control, safety protocols, and handling procedures associated with munitions. Using terms like "Not Hermetically Sealed" ensures that anyone handling the container is aware of its previous state and can take appropriate actions to manage the contents safely. This clarity helps prevent accidents or mishandling that could occur if the previous state is not communicated effectively.
