What must the AvSax contamination bag be before use?

The AvSax contamination bag must be vacuum sealed before use to ensure it remains sterile and effective for its intended purpose. The vacuum sealing process removes air from the bag, which helps to prevent contamination from external sources. This is crucial because the bag is designed to contain hazardous materials safely, and any exposure or compromise could lead to safety risks for both crew and passengers. Using the bag in a vacuum-sealed state guarantees that it is clean and prepared for immediate deployment when needed, ensuring compliance with safety protocols for handling contaminated items. Other states, such as being open, partially filled, or activated, do not offer the same level of sterility and safety that vacuum sealing provides.
