Black Diamond Avalung II Instrucciones De Uso página 9

If you are rendered unconscious, you may not be able to properly utilize
the AvaLung II even if the mouthpiece is in your mouth.
The AvaLung II will not clear debris should you vomit into it.
The AvaLung II will not work underwater.
Respiration through the AvaLung II in cold air can cause ice to form inside
the device's tubing and housing. Ice buildup could potentially restrict
airflow or impede proper function of the valves. As a general rule, do not
use the AvaLung II at temperatures colder than –20°C (-4° F). If you see
or suspect ice inside the AvaLung II, clear the device by shaking most of
the ice out of the mouthpiece or by thawing the ice and shaking the water
out of each end of the unit. If the AvaLung becomes blocked by ice or the
valves do not function due to icing, it must be warmed and cleared before
it can be effective. If the user becomes buried by snow, temperatures
within the snowpack will be warmer than the air temperature especially
once heat from the user warms the surrounding snow. This may help
reduce additional icing problems and potentially even thaw the device,
but only an AvaLung which is functioning before burial can be relied on
during a burial.
Since the AvaLung II is a breathing assistance device, there is always the
remote possibility that respiratory diseases could be transmitted if you
share or lend your AvaLung II. Your AvaLung II is personal and should not
be shared without being properly disinfected between users.
People having chronic respiratory diseases may have difficulty using the
AvaLung.
InspectIon And retIreMent
Thoroughly inspect the AvaLung II monthly during each season of use,
whenever you remove the AvaLung from the harness for cleaning and
whenever you suspect physical damage to the device. Inspect the AvaLung II
mouthpiece and exposed tubing and self-test the device by breathing
through it before and after each use. Retire it immediately if:
There are cracks, holes, distortion or breaks of any kind in a plastic
◆
component.
The mesh material covering the valve housing is ripped, thread-bare,
◆
or excessively worn.
There is significant crushing or discoloration of any of the tubing.
