As part of your basic familiarization with the Guardian, bailout procedures
are a
required
skill. In the event of an OOA situation, you must have
an available source of back-up air. Whether it’s a pony bottle or your
dive buddy, it needs to be close by. A practice session should start in the
shallow end of a swimming pool or similar environment, working either
at the bottom or a fixed point so you do not lose control of your depth or
position in the water column.
FOR BAILOUT PROCEDURES:
• ALWAYS have an available source of back-up air (pony bottle,
dive buddy, etc.) and know its location.
•
Do NOT hold your breath!
•
Start practice sessions in shallow end of swimming pool or similar
environment.
• During practice, work either at the bottom or a fixed point in the
pool.
•
It is recommended that you carry a spare visor-type mask.
First, know the location of your air supply, then start by removing the
Guardian FFM. This is best done by grasping the bottom of the mask
and placing your thumbs on the lower buckle tabs. Pull out on these tabs,
loosening and rotating the mask forward and back over your head. Exhale
slowly, do not hold your breath. Obtain your alternate air source, clear
the regulator, and breathe normally. You can now don a spare mask, or
terminate the dive without one.
This skill takes practice and preparation! Keep working on your
bailout technique until you are comfortable and it becomes second
nature.
Another important skill is donning the mask while underwater. Begin by
setting up the mask as you would donning it on the surface (extending the
straps, pulling any communications to the rear, etc.). Prepare yourself to
be without air for the short time it takes to perform this exercise. Remove
your spare mask, if you have donned one, as well as your alternate air
source. Again,
do not hold your breath
. Slightly exhale continuously.
Drop the mask over your head and press the mask to your face.
There are a couple of ways to clear the mask. If you have sufficient air in
your lungs, you can start to exhale as this will displace the water and clear
the mask. At the same time, look up at about a 45° angle, pull out slightly
on the bottom of the mask, then push the purge on the regulator. This will
clear the mask of the majority of the water.
