Objective: Respond to a simulated BCD low-pressure inflator (LPI) failure by disconnecting and reconnecting the BCD feed while you are underwater.
Value: If your inflator hose should malfunction or leak and let air uncontrollably into the BCD causing it to inflate, you can easily disconnect the hose and dump the excess volume in the BCD to establish neutral buoyancy.
How It’s Done:
- Pull the BCD connector backward to release the LPI hose from the BCD inflator.
- Establish neutral buoyancy.
- Let your buddy know what is happening, and prepare to simulate an ascent.
- If directed to do so by your instructor, orally inflate the BCD as a response to disconnecting the LPI.
- Reattach the LPI hose.
