Which preflight requirement for the Containment Bag is not required?

• A. Vacuum seal is not required
• B. The bag must be present in one or two sealed plastic bags
• C. The bag must be in a sealed bag
• D. Vacuum seal is required

Answer: (A)

The essential idea is containment through a reliable barrier. For preflight, keeping the contents from leaking or escaping relies on sealing the packaging rather than removing air from it. The Containment Bag needs to be placed inside a sealed outer barrier, often one bag or two bags, to create a continuous barrier that protects people and the environment during handling and transport. This approach provides redundancy and reduces the chance of a leak even if one layer is compromised. Because the main requirement is a secure seal, vacuum sealing isn’t a mandated step. Sealing the bags is sufficient to meet the containment goal, so stating that a vacuum seal is not required aligns with the standard practice. Vacuum sealing is not necessary for the preflight requirements and could introduce unnecessary complications, whereas the sealed-bag requirement directly supports containment.
