What should be checked for the crew life vest?

The correct choice highlights the importance of ensuring that crew life vests are secured in a manner that protects them from damage and maintains their functionality. Sealable storage can safeguard the life vest from environmental factors like moisture, dirt, or wear that could impede its effectiveness in an emergency situation.

Maintaining crew life vests in a sealed condition ensures they are in optimal condition when needed. However, a well-designed life vest is typically stored in a way that allows easy access, as crew members must be able to quickly retrieve and don the vests in the event of an emergency. Moreover, visibility and accessibility are also crucial for effective emergency management, allowing crew members to locate and use the vests rapidly. Thus, while a life vest being sealed is an important aspect, it must also strike a balance with the need for quick access and usability in emergencies.
