What is a Type 1 life jacket?
Keeping this in view, what is a PFD Type 1?
However, recent changes to the Australian Standard rely on a description of buoyancy rather than type. PFD Type 1. A PFD Type 1, or 'lifejacket', is intended to maintain the wearer in a safe floating, 'face up' position whether conscious or unconscious, with sufficient floatation to support the body and head.
Considering this, what is Type 2 life jacket?
Type II: Near-shore Vests: Calm inland waters, where a quick rescue is likely, is the intent of these PFDs. They will turn some unconscious wearers to the face-up position but not all of them. Foam Type II's are 'bulky' and not generally comfortable to wear while sailing, but less 'bulky' than foam Type I's.
The outer shell of a life jacket is usually made of nylon or vinyl with material that keeps the life jacket afloat sewn inside. There are three classifications for the substance inside a life jacket: inherently buoyant, inflatable and hybrid. These life jackets have cartridges of carbon dioxide gas sewn into them.
