Your auto-inflating PFD will possible be equipped that has a Hammar inflator. These are generally purported to inflate only when they're exposed to enough force, at which issue the inflator “will open their hydrostatic valve, letting the drinking water to meet the water-sensitive ingredient and begin the activation,�?writes Hammar. Picture courtesy of Hammar. Lately, I’ve heard about device failures from security experts who direct PFD demonstrations across the state.
