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 at the bottom or a fixed point in the pool.
• It is recommended that you carry a spare mask.
Emergency Procedures
First, know the location of the alternate air supply, then remove the
Spectrum FFM. This is best done by grasping the bottom of the mask
and placing the thumbs on the lower buckle tabs. Pull out on these tabs,
loosening and rotating the mask forward and back over the head. Exhale
slowly, do not hold breath. Obtain the alternate air source, clear the
regulator, and breathe normally. Don a spare mask, or terminate the dive
without one.
This skill takes practice and preparation! Keep working on the bailout
technique until mastering this skill.
Another important skill is donning the mask while underwater. Begin by
setting up the mask in the same way as donning it on the surface (extending
the straps, pulling any communications to the rear, etc.). Prepare to be
without air for the short time it takes to perform this exercise. Remove the
spare mask, if applicable, as well as the alternate air source. Again, do
not hold breath. Slightly exhale continuously. Drop the mask over the
head and press the mask to the face.
To clear the mask of water, if you have sufficient air in your lungs, 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 halfway. This will clear the majority of
the water from the mask.
If there is not sufficient air in the diver’s lungs, push the purge button of the
diver’s regulator until the mask is cleared of water.
Take a cautious breath to ensure the mask has cleared and to prevent
inspiring any residual water. After the first inhalation, pull down on the
drain tab, look down and exhale forcefully to clear any remaining water.
Repeat this forceful exhalation a few more times. Again, ensure this skill
is mastered.
