INFLATING YOUR
INFLATABLE PFD
Practice inflating the device.
It is recommended that the
following procedures are
followed to inflate your
inflatable PFD:
1. Manual inflation
Actuate the inflation
system by jerking firmly
downward on the pull tab.
The PFD should fully inflate
within 5 seconds (Fig. 11 for
the MD2010, Fig. 12 for the MD2012)
2. Oral inflation
Properly armed and inspected, manual Inflatable
PFD models will inflate. However, should inflation
not occur, or in a non-emergency situation, you can
fully inflate the PFD by mouth (Fig. 13). To orally
inflate the PFD, first locate the oral inflation tube
by opening the wearer’s left front panel of the
PFD. Then remove the dust cap from the end of
the oral tube and blow into the tube until the PFD
is fully inflated.
3. Automatic backup inflation (MD2012 only)
Inflation will occur automatically within seconds
after the inflator is immersed in water. The
water-sensing bobbin will disintegrate, triggering
a spring-loaded plunger, which punctures the CO2
cylinder to inflate the cell (Fig. 4).
Information for both models: The carbon dioxide
used to inflate PFDs will slowly permeate through
the fabric cell 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.
