Individual flotation devices on the B737-300 are called?

• A. Double chamber life vest
• B. Single chamber & infant life vest
• C. Quartet life vest
• D. Triple chamber vest

Answer: (B)

The naming reflects the two standard forms of passenger flotation gear on a B737-300: an adult life vest with a single buoyant chamber and a separate infant life vest for children. The single-chamber design refers to one buoyant section that provides flotation when worn, which is the common configuration for adults. Infants require a smaller, specifically sized life vest designed for them. Terms like double, triple, or quartet chamber vests aren’t used for this aircraft’s cabin equipment, so the combination of a single-chamber adult vest and an infant vest best matches what’s provided.
