What does a Type I life jacket do for unconscious wearers?

A Type I life jacket is specifically designed to provide the highest level of buoyancy and to turn most unconscious wearers face up in the water. This capability is crucial because it ensures that the wearer's airways remain above the water, thereby reducing the risk of drowning. The design and construction of a Type I life jacket take into consideration the need for quick response in emergency situations, making it an essential safety device for individuals who may be incapacitated due to various reasons while in the water.

In contrast, other types of life jackets might be made for comfort, lack the capacity to turn wearers face up, or be size-specific, such as those intended only for children. However, the primary purpose of a Type I life jacket is to maximize safety for all users, particularly in situations where they may be unable to help themselves.
