Lifejackets - inflatables
Just wondered what others views are about the following and whether anyone knows the answer:
The definition of a lifejacket (as opposed to a buoyancy aid) is that it will turn an unconcious casualty onto their back allowing them the chance to breath. How is it therefore that a manual inflation lifejacket is just that - a lifejacket - as by definition if the user cannot inflate it, it cannot turn them over.
Sorry, but was posed this question by a student at the weekend on a level 2 course and didn't have a credible answer (was pleased to be using auto inflation lifejackets though!)
