What type of PFD are the anti-exposure coveralls classified as?

Anti-exposure coveralls are classified as a Type I personal flotation device (PFD). This classification is primarily due to the coveralls’ design, which is intended to provide maximum floatation and thermal protection in cold water environments.

Type I PFDs are specifically designed for use in open water and are very buoyant, allowing for effective flotation even in rough conditions. They offer the best chance of survival for individuals who may be incapacitated or unable to swim. In the case of anti-exposure coveralls, they incorporate buoyancy elements that help keep the wearer afloat while also minimizing the risks posed by hypothermia when exposed to cold water.

Other types of PFDs serve different purposes. For example, Type II devices are primarily intended for near-shore activities where quick rescue is likely, and Type III devices are designed for comfort during activities where continuous wear is expected, such as sailing or kayaking. Type IV devices, such as throwable cushions or rings, are meant as a supplementary aid and are not designed to be worn. Understanding these classifications helps ensure the appropriate PFD is selected based on the specific water conditions and the activity being undertaken.
