What color seal indicates that the EMK must not have been opened and meets FAA requirements?

The green seal indicates that the Emergency Medical Kit (EMK) has not been opened and meets the Federal Aviation Administration (FAA) requirements. This color coding is crucial for ensuring the integrity of the medical supplies within the kit. When the EMK is sealed with a green seal, it signifies that all contents are accounted for and that the kit is ready for potential use in case of an emergency onboard.

The presence of a green seal allows crew members to quickly verify the kit's status without needing to open it, thus ensuring that it has not been tampered with or used prior to an emergency. This process of color-coding seals is a part of maintaining operational safety and compliance with regulatory standards.
