3.The PFD could inflate when you are in an awkward place or position.
Owners of inflatable PFDs must understand the unique characteristics of these products so that they can use them safely.
You must learn how to properly arm the PFD.
Why: An improperly armed mechanism may not inflate the chamber. This PFD will not float you without being inflated.
You must check the status of the mechanism and the CO2 cylinder before each outing. If the cylinder cap is punctured there will be no gas to inflate the PFD. Also, if the cylinder is deformed in any way, there may not be gas to inflate the PFD.
Why: This PFD will not float you unless it can be inflated.
Why: Are you sure that no one else inflated the PFD recently and did not replace the cylinder?
Why: Premature inflations that occur on a stored product may go unnoticed since the CO2 gas will permeate the chamber fabric within a few days, leaving a deflated chamber.
Why: U.S. Coast Guard studies have shown high percentages of unserviceable inflatable PFDs with used cylinders in them when used by recreational boaters.
In addition to inspecting the mechanism and cylinder before each outing you must periodically check the other components of the PFD. This would include the chamber, webbing, buckles and thread.
Why: The chamber may get punctured, or abraded to the point where it will not stay inflated.
Why: Over time these components can wear out and not be strong enough to perform their intended function when needed.
Premature or unexpected inflation of automatic devices may occur in high heat and humidity storage conditions or when exposed to severe conditions such as being innundated by water from waves breaking on deck. Premature inflation creates risks you must address.
Why: Inflation when stored in a tight space could damage the PFD.
