Automatic Backup Inflation
Inflation will occur automatically within 5 seconds after the inflator
is immersed in water. The water-sensing element will disintegrate,
triggering a spring-loaded plunger, which punctures the CO
2
cylinder
inflating the Inflatable Vest with LIFT TM (Fig. 7).
NOTE: When inflated, the carbon dioxide (CO
2
gas) used to inflate
PFDs will slowly escape through the 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 prolonged immersion.
Oral Inflation
Properly armed and inspected Inflatable Vest with LIFT
TM PFDs will inflate
when manually or automatically activated. However, you can fully inflate
the PFD by mouth (Fig. 8) should inflation not occur, or if you are in a
non-emergency situation.
To orally inflate the PFD, first locate the oral inflation tube by opening
the wearer’s right front panel cover 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.
