Black Diamond Avalung Notice D'utilisation page 5

users of nose clips may significantly reduce the possibility of carbon dioxide
contaminated air in the facial area due to nasal exhalation; however, the
violent nature of many avalanches may make it impractical to get the nose
clips in place and potentially difficult to keep them on even if they are on
prior to being caught in the avalanche.
8. To ensure that the device will function effectively without the added
benefit of nose clips, Black Diamond has conducted controlled tests
of the AvaLung without nose clips, and had over 20 test burials which
lasted 60 minutes or longer. Without the AvaLung, test subjects typically
encounter serious medical problems within five to ten minutes. If you
become buried without the nose clips on, remain calm and focus on
exhaling only through the AvaLung.
9. Once in your mouth, the mouthpiece
the AvaLung system to function properly. In the case of an impending or
actual burial, keep the mouthpiece firmly in your mouth (holding it firmly
in your mouth with your teeth will improve your chances of keeping the
mouthpiece securely positioned in your mouth). Your mouth must remain
closed to prevent loss or displacement of the mouthpiece and to avoid snow
entering your mouth. Snow in your mouth could result in a blocked airway
and eliminate the effectiveness of the AvaLung system or your ability to insert
it in your mouth. If buried, keep your lips closed around the mouthpiece,
keeping it securely sealed and only breathe through your mouth. If jaw
muscles tire and you are stationary, you can move the mouthpiece from
between your teeth to the front of your gums but always keep your lips sealed
to prevent exhausted air from being expired in front of your face.
NotE: Failure to have a secure mouthpiece placement may result in your
failure to be able to properly use the AvaLung system.
10. When the Avalung system is not in direct use and there is no
avalanche related risk to the user, the mouthpiece may be stored in the
mouthpiece pocket. When anticipating the need to use the AvaLung,
the mouthpiece MUSt be either in your mouth or in the ready position.
When in the properly adjusted ready position, the mouthpiece should
be capable of being quickly inserted into your mouth.
11. The AvaLung system should be dried after each use. It should also be
cleaned regularly, before being stored and at the start of each season
before use (see Cleaning instructions).
