3) Oral Inflation
Properly armed and
inspected Inflatable PFDs
will inflate when manually
or automatically activated.
However, you can fully inflate
the Inflatable PFD by mouth
(Fig. 4) should inflation not
occur, or if you are in a non-
emergency situation. To orally
inflate the Inflatable PFD, first
locate the oral inflation tube
by opening the wearer ’s left
front panel of the Inflatable
PFD. Remove the dust cap from the end of the oral tube and blow into
the tube until the Inflatable PFD is fully inflated.
Place the oral inflator dust cap back in the stowed position (Fig. 6).
WARNING: Avoid double inflation (CO
2
cylinder inflation
after full oral inflation) as it could damage the PFD.
SPECIAL CONSIDERATIONS FOR
AUTOMATIC DEVICES (MD2016)
The Inflatable PFD might not be armed when needed, either knowingly
or unknowingly. Premature automatic inflation causes several risks
that you must address to avoid drowning. Much less common but also
important are:
WARNING: Avoid double inflation (CO
2
cylinder
inflation after full oral inflation) as it could damage the
PFD.
1) Inflation when stored in a tight space could damage the PFD, and
2) The PFD could inflate when you are in an awkward place or position.
Premature inflation may occur in certain conditions, including
when the device is subjected to: heavy splashing, high humidity,
heavy fog, and heavy rain.
