LIFE JACKET & LIFE BUOY RING
The different types of life jackets (also referred to as PFDs personal Flotation Devices) can help you decide which are appropriate for your crew members. Inflatable PFDs have manual or automatic inflation with oral inflation as a back-up. Manual system are the simplest to maintain and less susceptible to unwanted or inadvertent inflation, but rely entirely on wearer activation. The user activates the manual system usually by pulling a lanyard, which inflates the device with a carbon dioxide cartridge.
