Marine accidents involving fishing boats, etc. at sea in cold waters, etc.
In preparation for accidents such as falls into the sea during fishing operations and other disasters, workers are required to wear work uniform-type cold-resistant, waterproof life jackets even during fishing operations. This type of cold-resistant waterproof life jacket is particularly effective when the jacket is made inflatable to provide buoyancy and the air chamber is divided into several parts.
Each air chamber can be expanded evenly with a minimum of expansion devices, and the gas that enters each air chamber does not flow backwards.
Maintaining internal pressure requires a gas passage that can maintain buoyancy even if one air chamber is damaged due to some influence.
