What is a key requirement for the first aid kit before departure?

A key requirement for the first aid kit before departure is that one seal must be present. This indicates that the kit has not been tampered with and is in a condition ready for use in case of an emergency. The presence of a seal ensures that the contents are intact and have not been accessed or used, which is crucial for the safety protocols on board. In an emergency, it is vital that flight attendants can trust that the first aid supplies are available and fully stocked.

The other options do not meet the necessary criteria for a first aid kit. For instance, a kit that is packed with three seals may indicate it has not been opened, but it is not a standard requirement; the important factor is that at least one seal maintains its integrity. Leaving the kit unsealed does not comply with safety regulations, as it could lead to potential unauthorized access or use of its contents. Storing the kit in the galley is also not typically aligned with regulations; first aid kits are usually located in accessible areas for crew readiness throughout the cabin.
