Personal flotation device - Wikipedia, the free encyclopedia |
 | | Life jackets for large commercial transport in potentially dangerous waters, such as coastal cruises and airlines, are often a sealed suit of heavy vinyl with an inflatable air chamber, and usually provides more buoyancy than its foam counterpart. |
 | | The life jackets suited for this purpose are often also equipped with survival kits, usually containing signalling devices, first-aid kits, food, water, and shark repellent. |
 | | Life preservers are usually torus shaped when mounted at the ready on the deck of a ship, but also are made in the shape of a vest which can be worn by passengers during an evacuation. |
