Information
When inflated, the carbon dioxide (CO
2
gas) used to inflate the PFD
will slowly escape through the fabric over time. A slight reduction
of pressure will be observed after several hours of inflation. Topping
up by oral inflation may be required in the event of very prolonged
immersion.
IMPORTANT: See Special Considerations for Inflatable Devices

Properly armed and inspected

NOTE: Oral inflation may cause the Inflatable PFD to break-out

inflated.

full oral inflation) as it could damage the PFD.
