Inflatable Life Jacket Regulations in the United States Inflatable life jackets are only permitted to be worn by those aged 16 and over. While aboard a boat, inflatables must be worn at all times (unless passengers are in an enclosed cabin and they must be readily available in this case). Inflatables are also required to have some sort of identification indicating that the wearer is legally allowed to wear the jacket. In addition to these regulations, state laws may also apply. For example, in New York City, people under 18 cannot wear an inflatable life jacket. The same goes for Washington, D.C. Also, wearing an inflatable life jacket on a vessel carrying hazardous materials is prohibited. People who wear inflatable life jackets enjoy increased safety because they can float away from a ship if it should sink. In addition, these jackets are easier to wear than traditional life vests and can provide better protection against heat-related injuries or violence. However, not everyone agrees that inflatable life jackets are a good idea. Some critics say they are too bulky and expensive and that they offer users less protection than traditional vests. In addition, some states do not allow children to wear inflatable life jackets because they suspect this will make them want to stay on board longer. Finally, some people believe that wearing an inflatable life jacket violates naval etiquette because it makes others feel uncomfortable.
