A transceiver does not protect you against
As a winter outdoor enthusiast, you must consider all
possible avalanche prevention measures and plan
your trips carefully. Companion rescue – the worst
case – must be practiced frequently. Under the stress
of an accident, this is the only way you will be able to
locate and dig out a companion quickly and efficiently. Despite practice and all the technological
advancements, by far not all of the completely buried
avalanche victims are rescued! An avalanche burial is
always life threatening.

Handling the Barryvox
As all transceivers, the Barryvox contains shock-sensitive ferrite antennas. Therefore, you should handle it
with utmost care!
Store the device and the carrying system in a dry
spot that is protected from extreme cold or heat and
direct sunshine.
It is recommended that you have the functionality
tested at regular intervals (see chapter «Periodic
As a matter of principle, avoid having other electronic
devices (e.g. mobile phones, radios, headlamps),
metal objects (pocket knives, magnetic buttons), or
other transceivers close to your running avalanche
transceiver. The PULSE Barryvox® contains a magnetic compass. You should not wear clothing with
magnetic buttons! Users of pacemakers are
advised to carry the device on their right side
(adjust the length of the carrying straps). Consult
the manufacturer’s instructions with regard to the
impact on pacemakers.
When searching, hold the device at a minimum of
50 cm away from these objects and turn off any electronic devices, if possible. It is highly recommended
to turn off mobile phones!
The Application Safety Guide of the Barryvox contains
an exhaustive list of allowed equipment as well as a
detailed list of possible limitations.
( or
When the main switch is moved from the OFF to the
SEND or SEARCH positions, the transceiver is turned on.
While starting, the device conducts a self-test.
The microprocessor, the antennas, the sensors, and
the display are checked. If the battery level is low,
the self-test will not run.
If the self-test is completed successfully, the display
will show «OK» and the transceiver will beep three
The remaining battery level is displayed as a percentage.
If the self-test fails, an error message is displayed for
20 seconds along with an acoustic warning.
The meanings of the different error messages are
described in the chapter «Troubleshooting».
Carrying Positions
Regardless of the carrying position, the display
should always face your body!
The detection of vital data is only possible if you
carry the device in the carrying system.
(Chapter «Triage Criteria an Vital Data»)
Before you use the device for the first time in the outdoors, or when you decide to carry the transceiver in
a different manner, we recommend that you test the
vital data sensor (Chapter «Vital Sensor Test»).
2.4.1 Carrying System
(Recommended Carrying Position)
The carrying system has to be put on your innermost
layer of clothing prior to beginning the trip (see illustration) and has to be worn on your body for the duration of the trip. The transceiver shall always
remain covered by one layer of clothing. The
device itself is inserted into the carrying system
according to the illustration. It should always remain
anchored to the base plate of the carrying system
using the red hook on the wrist loop.
Turning the Device On
2.4.2 Carrying the Transceiver in a Pocket
(without vital data
If you carry the Barryvox
in a pant pocket, the zipper must remain closed
for the duration of the trip.
Always use a secured
pocket (see illustration). If
possible, attach the wrist
loop to your pants or
secure it around your belt.
Test your Barryvox at home prior to your trip. Turn the
transceiver on and monitor the self-test and the battery level. This gives you the opportunity to replace
low batteries and have an eventual defect repaired
Battery Level Indicator
The following table gives you average values for the
battery levels.

Group Check
Before a party takes off, the transceivers of all the
party members must be checked. To conduct this
test, the function group check is activated on a single
transceiver within the party. Activate the group check
by switching the device from OFF to SEND and pressing either of the keys within the first 5 seconds. After
a few seconds, the device will automatically activate
the group check. Make sure all the other transceivers
of the party are in SEND mode.
The test is successful if all the members of the party
can clearly hear beeps within the range indicated on
the display. The members of the party must be spread
out appropriately to avoid mutual interference. If the
individuals are too close to each other, the group
check’s results become increasingly unreliable.
If no tone is heard within the indicated range, the
device may not be used, and the device or its batteries must be inspected further, as needed.
After 5 minutes in the group check, the transceiver
automatically switches to the SEND mode. The user is
warned ahead of time by an acoustic alarm. This
automatic switching can be prevented by pressing
any button within 20 seconds. After the group check,
the transceiver must be switched to the SEND mode
by pressing any button.
Two-Way Group Check
We recommend you perform a two-way group check
in which the SEND and the SEARCH functionality are
checked individually!
The members of the party activate the group check
on their transceivers or set them to a low receive volume. The leader switches his or her transceiver to
the SEND mode and ensures that all party members
can receive. Subsequently, the party members switch
their transceivers to SEND, and the leader activates
the group check or sets the transceiver to a low
receive volume. The SEND mode of all transceivers is
checked, and ultimately the leader switches his or
her transceiver to SEND.

The SEND mode is the normal operating mode outdoors or in all other situations in which there is a risk
of avalanches.
Each individual signal pulse is tested. If the test is
successful, this is confirmed by a blink of the red
SEND-Control LED.
The LCD display is automatically deactivated in the
SEND mode, but can be activated any time by pressing either of the keys.
In case of a burial (or whenever the transceiver stops
moving), the device records the burial duration and
detects vital data. These are displayed on the buried
device and transmitted via W-Link to all other transceivers capable of receiving vital data. See chapter
«Burial and Vital Duration».
Electronic devices and metal objects can interfere
with the search or make it impossible.
See chapter «Interferences».
Although the avalanche transceiver is easy to use,
its effective use requires proper training. We recommend that you practice transceiver searches
Search Phases
In an avalanche search, the following phases are distinguished:
Primary search phase
Secondary search phase
search phase
search phase
Coarse search
4.1.1 Primary Search Phase
From the start of the search until you clearly hear the
first tone, you are in the primary search phase.
During the primary search, the avalanche surface is
searched systematically until you pick up a signal.
The objective of the primary search phase is to detect
a signal.
The PULSE Barryvox® uses the symbol
as a
generic instruction to apply one of the following
search patterns for new signals!
Regardless of the operating mode, the following
search strategies apply:
Search strategy if the
last seen point is
known. The primary
search strip extends
downhill from the last
seen point in the direction of the slide.
Last seen point
To optimize the range, rotate the transceiver
around all axes.
Once a signal is received, maintain the device orientation and continue walking until the signal can be
heard clearly. The primary search phase is concluded.
4.1.2 Secondary Search Phase
The basic pattern of the primary search is suspended
and the signal is followed to the buried subject.
Just as in traditional analog transceivers, the analog
tone is just received by one antenna. The change in the
distance indication can therefore deviate from the
change in tone volume. Depending on the relative orientation of the transmitter to the receiver, the tone volume
and the distance indication may both decrease while
approaching the buried subject.
Search strategy if the last seen point is unknown.
Single rescuer
Multiple rescuers
Optimization of the range
Coarse Search: From where the signal is first
detected to the approximate location of the
buried subject.
Pinpointing Phase: Pinpointing occurs in the
immediate proximity of the buried subject using
the transceiver together with a probe pole.
Auto-Revert to SEND
Analog Search Tone
Standard Mode
As soon as the device is switched to SEARCH, it is
operating in standard mode. This mode enormously
facilitates a rapid location of a buried subject.
Auto-revert to SEND automatically switches the
transceiver from the SEARCH mode to the SEND
mode if no user interaction or movement occurs during a certain amount of time (default 8 minutes).
Prior to reverting, the device will sound an audible
alarm. Reverting can be avoided if either of the keys
is pressed within 20 seconds of the alarm.
This setting automatically reverts a transceiver, which
was unintentionally left in SEARCH mode (after a
search or an exercise), back to the SEND mode.
In case rescuers are buried in a second avalanche,
this function allows them to be located using transceivers.

Below 3 meters:
Pinpointing with
cross bracketing
The analog tone is the first signal that is received at
long distance.
If the distance to the buried subject is less than
approx. 60 meters, the distance and direction are displayed. The sensitivity (volume) of the receiver is
adjusted automatically to optimize the processing of
the signal. The distance can never be determined
exactly. The numbers must be interpreted as relative
distances. Whether the numbers are increasing or
decreasing is more important than the absolute numbers. The closer you are to the transmitting device,
the more precise the indicated distance is.
Above 3 meters:
Secondary search with
distance and direction
Hold the transceiver horizontally in front of you
and proceed in the direction indicated by the
arrow. If the distance increases, you are moving
away from the victim. Continue the search in the
opposite direction. The transceiver will lead you to
the buried subject quickly and reliably.
Do not move backwards, otherwise the direction
indication will be incorrect.
Above approx. 60 meters:
Primary search with analog tones
Start the search at a high speed and reduce this
speed as you close in on the buried subject. Operate
the transceiver in a quiet and concentrated manner avoid rapid movements. This way, you will reach the
objective in the quickest and easiest manner!
At this point, you must hold the transceiver just
above the snow surface and determine the point
with the smallest distance reading by bracketing.
Within the pinpointing range, i.e. within the immediate proximity of the buried subject (< 3 meters), the
Barryvox provides you with a digital distancedependent tone while pinpointing.
Use the avalanche probe to complete locating the
buried subject (See chapter «Companion Rescue»).
A located subject should only be marked using the
✓-Mark function after his or her location has been
verified using a probe pole!
Do not place the Barryvox on the snow surface again
for this purpose!
Hold the transceiver
directly above the snow
surface while pinpointing!
Erase Mark
A mark can be removed by selecting the buried subject with the -key and selecting «Erase mark» with
the -key. You can only remove the mark if you are
in the immediate vicinity (< 6 m) of the buried subject.
Deep Burials
Exact pinpointing with
the avalanche probe
Don’t mark the location of
a buried subject until the
location has been confirmed using a probe pole!
Do not place the Barryvox
on the snow surface
again for this purpose!
After marking a subject’s location, the Barryvox
searches for other possible burials, displaying the primary search symbol
and advising you to search
the rest of the avalanche (See chapter «Primary
Search Phase»).
If a buried subject is marked with a distance reading
above 3 m, an additional safety dialog appears asking
you to confirm the successful location of the subject.
Marking a buried subject in more the 6 meters depth
is not possible.
Search for further buried
Flux line search
4.4.3 Search for Multiple Buried Subjects
Using the Standard Mode
In standard mode, the transceiver attempts to analyze
all the detectable signals and to determine the number of buried subjects. This is possible, because all
the signals from one transmitter display characteristics, which are distinguishable from the signals from
other transmitters. The more unique the signal characteristics are, the more accurately the signals can
be distinguished and located (pattern recognition). By
automatically associating the signals with their
respective sources, multiple burial situations can be
solved without applying specific search tactics.
List of Buried Subjects
The buried subjects are listed based on the distances.
The device favors the closest subject first. Locate the
various buried subjects using the transceiver and
probe pole (Chapter «Search for a Single Buried Subject using the Standard Mode»).
As soon as you mark an individual subject, the transceiver takes you to the nearest, unmarked buried
Continue this procedure until all subjects are located
and marked.
The rescuer now searches for additional buried subjects while the display shows the symbol for the primary search phase
to indicate that the rest of the
avalanche surface must be searched (Chapter
«Primary Search Phase»).
Procedure for multiple burials
Vital Data Display
Search Suspension
If it is not possible to locate and dig out all buried
subjects at the same time, the buried subjects with
higher chances of survival, indicated by the
symbol, should be located and excavated first.
During the search for multiple subjects, signals may
overlap making it impossible to analyze the signal of
a single buried subject. If the signal overlap lasts
several seconds, the rescuer has to interrupt the
process temporarily to avoid deviating from the optimal search path. The PULSE Barryvox® will indicate
the necessity to suspend the search by displaying the
word «Stop». Stand still, and do not move until the
word «Stop» disappears, at which time you can continue to search.
You can find more information on triage criteria and
vital data in the chapter «Triage Criteria and Vital
Data». The actual prioritization of certain buried subjects over others is up to the rescuer.
4.4.4 Limitations
Analog Tone
The larger the number of buried subjects is, the more
difficult and time-consuming the exact analysis of the
situation gets, because of overlapping signals. The
more signals there are, the longer the signal overlaps
can last. The capability to automatically detect and
isolate signals from multiple buried subjects is therefore limited.
Outside of the pinpointing range, the Barryvox always
provides the analog tone allowing the rescuer to verify
the number of signals detected by the device. Counting the number of different tones provides the number
of buried subjects.
If the + sign appears for an extended period of time,
this indicates that not all the buried subjects can be
located using the standard mode. In this case, it is
advised to switch to the analog mode.
Analog Mode
In the analog mode, the transceiver shows distance
and direction to the subject with the strongest signal
and provides an analog tone. The analog mode is
mostly used when a clear distinction of multiple
burials is no longer possible in standard mode.
Switching from standard mode to analog mode is
achieved by pressing and holding both keys at the
same time for three seconds.
4.5.1 Multiple Buried Subjects in Analog Mode
If multiple burials are detected in analog mode, an
icon symbolizing multiple burials is shown on the display
. Additionally, you can also hear the analog
tones. These are helpful in distinguishing the signals
acoustically. The device favors the closest subject.
The detection of multiple burials may vary based on
the subject’s orientation and distance relative to the
Turn off the transceivers of the excavated subjects to
facilitate the further search. If you don’t know the
number of buried subjects, you must search the
entire avalanche path using the search patterns
described in the chapter «Primary Search Phase».
In analog mode, the direction indication always points
forward, never backwards. Monitor the distance indication to ensure you are approaching the buried subject!
Analog Mode
Number of Burials
The calculated number of burials is displayed below
the list of buried subjects. If the transceiver detects
more signals than buried subjects in the list, a + sign
is added behind the number.
If the rescuer detects problems with the analysis of a
multiple burial situation, he or she can always switch
to the analog mode (see chapter «Analog Mode»).
The list of buried subjects is deleted at this time.
4.5.2 Search Tactics with Multiple, Widely
Scattered Burials
Continue to search for other buried subjects by
returning to the previously marked point.
Mark the location on the avalanche where the «multiple burial» icon
appeared on the display or where
you left the primary search pattern.
Strictly adhere to the primary search pattern and
continue down the avalanche path until you are led to
the next subject. Initially, the transceiver will want to
take you to the previously located subject, because
he or she is still the closest. Ignore these indicators
until you notice that the transceiver is pursuing a new
Search for the first buried subject using the information on the display along with the analog tones. Once
this subject is located, you or other rescuers should
dig him or her out immediately.
Search tactics with multiple, widely scattered burials in analog mode
4.5.3 Search Tactics with Multiple Burials
in Close Proximity
The interpretation of the acoustic signals is extremely
important in this situation. These must be interpreted
in connection with the distance readings.
You hear three beeps and the distance reading jumps
between 3.5 and 4.8 m. Therefore, three buried subjects can be expected within a radius of 5 m.
Maintain the orientation of the transceiver during this
phase and concentrate on the increase or decrease of
the distance indication as well as the volume of the
analog tones.
At the point with the lowest distance reading, you
leave the micro search strip pattern to pinpoint the
buried subject through bracketing. Once the subject
is located, you return to the location where you left
off in order to continue the pattern.
Search Using Micro Search Strips
If you have multiple burials within less than 10 to
15 meters, you search using micro search strips.
Locate and dig out the first buried subject.
Back up until the display shows 15 and search the
area in front of you in parallel search strips.
As soon as the distance indication reads 15, you have
reached the side of the search strip. Advance 2 to 5
meters and return on the next parallel search strip
until this search strip ends as well (distance indication > 15).
The more buried subjects there are and the closer
these are, the tighter the micro search strip grid on
the potential search area should be. As a rule of
thumb, the search strip width should be between 2
and 5 meters.
Continue the pattern, until the distance reading in an
entire strip never drops below 15. Then revert to the
primary search pattern and search the rest of the
The avalanche probe is very helpful in locating multiple buried subjects in close proximity.
There are at least three buried
subjects within 15 meters.

Advanced Features
4.5.4 Further Search Methods
Advanced Features
There are further methods to search for multiple
buried subjects in close proximity.
One method uses concentric, circular search strips
with radiuses of three, six, and nine meters around
the first located subject. As with the micro search
strips, the locations with the strongest signal strength
are of interest. From there the subjects are located
using a traditional bracketing method.
Manual Volume Control in Analog Mode
(Analog Mode = Manual)
In the analog mode (with activated manual volume
control), the receiver sensitivity (volume) can be set
manually. This makes acoustic searches possible, as
conducted with traditional transceivers.
Buried subjects are located based on the acoustic
change in intensity of the received signal. The use of
this mode requires intensive training.
In order to be able to use the manual volume control
in analog mode, you must enable it in the «Settings»
by choosing «Manual» in the setting «Analog mode».
When using the manual volume control in analog
mode, the display can be disabled, in order to
significantly increase the range. By pressing the
- key for + on volume level 8, the display is
deactivated; subsequently pressing the
- key
for – activates the display again.
By activating the manual volume control in analog
mode, an analog tone is used for the group check,
as well.

Advanced Features
5.3.1 Language
5.3.5 Auto-Revert to SEND
5.3.7 Owner
This setting allows you to select the language of your
transceiver’s user interface.
Auto-revert to SEND switches the transceiver from
SEARCH mode to SEND mode if there is no user interaction or major motion for a specific amount of time.
The default setting of 4 minutes is appropriate for
most users. Only change this setting if you have an
important reason to do so. The setting is critical for
your personal safety! If you disable this setting, you
will always see the warning symbol
The Barryvox allows you to enter your name, address,
and other information, such as your phone number or
email address. This information is displayed every
time the transceiver is turned on, so that the owner
can be identified immediately anytime. We recommend that you enter this information.
5.3.2 Analog Mode
The analog mode allows the rescuer to solve even
most complex multiple burial situations and makes
the PULSE Barryvox® a full-fledged avalanche transceiver. If the analog mode is set to «Manual», the
experienced rescuer can adjust the volume manually,
which can be very advantageous in certain situations.
5.3.3 Audio Support During Pinpointing
(< 3 Meters)
During the pinpointing phase, the search can be supported with an acoustic tone, which leads you in the
right direction. Rescuers who prefer always to hear
the analog tone can disable this feature.
5.3.4 Pinpoint View (< 3 Meters)
Within pinpointing range, the Barryvox supports you
with a cross symbol for bracketing, which allows for
user-friendly pinpointing. Users who are very familiar
with the flux line pattern in close proximity of the
transmitter and prefer to see the direction arrow can
disable this feature.
5.3.6 Vital Data
Your PULSE Barryvox® detects your vital data while
you are buried and transmits these via the W-Link
radio connection to the rescuers (default setting). In
SEARCH mode, the Barryvox displays the vital status,
provided the sender has enabled the W-Link and the
ability to transmit vital data.
If you do not wish to have these data transmitted, you
can disable this feature. Only change this setting if
you have an important reason to do so. This setting
can affect your chances of survival in a complete
burial situation as well as those of buried subjects
you are searching for.

The PULSE Barryvox® uses a W-Link radio transmission.
Different countries have varying frequency regulations.
The following world map shows the frequencies used in
the individual countries. Note that specific frequencies
may not be used in certain countries. The frequency
is factory set depending on the country of sale. The
manufacturer declines all liability in the case of
after-sale frequency modifications.
The electronic compass provides a rapid adjustment
of the direction indicator and extends the display
range to 360 degrees. To function properly, the compass must be calibrated. The need to calibrate the
compass is automatically detected when the batteries
are replaced. This is, however, not the case if you
travel a long distance.
The function «Reset device» allows you to restore all
the default factory settings. All modified settings as
well as owner data are lost.
Tone-only Mode (TOM)
Rotate the horizontal transceiver slowly and with constant speed around its axis until the message «Compass calibrated» appears.
If the display is defect, you have to search using the
tone-only mode. Turn the transceiver off. Press both
keys while turning the transceiver back on. The sensitivity of the receiver can be manually adjusted by using
- key= + and
- key = –. The analog tone is
used to locate buried subjects.
The use of earphones in avalanche rescue is especially advantageous in high-noise environments
(wind, helicopters, etc.).
Standard (Walkman) earphones can be used. As soon
as earphones are plugged in, the internal speaker is
muted so that other rescuers are not disturbed.

Periodic Checks
There are various test and configuration adapters
available for the PULSE Barryvox®, which allow
advanced functions to be configured or restricted.
Test, configuration, and update capabilities via the WLink make the PULSE Barryvox® the ideal choice for
fleet use.
To ensure the proper functionality of the transceiver,
it is highly recommended that you send your device
to a service center listed on the inside of the cover
once every three years for a functional test. There is
a service charge involved. This functional test is far
more comprehensive than the self-test or group
check. Preferably, you will have the periodic check
conducted during the summer months, so that your
Barryvox is ready at the beginning of the winter season. The recommended date of the next check can be
viewed under «Maintenance».

Companion Rescue
Companion Rescue
Companion rescue means that buried subjects are
located and excavated by members of their party
immediately after the avalanche slide. Avalanche rescue is a race against time! While most buried subjects can be rescued within the first 15 minutes, the
chances of survival decrease rapidly afterwards.
Companion rescue, therefore, provides the greatest
chances of survival for a buried subject.

Triage Criteria and Vital Data
7.4.1 Triage
With limited resources (few rescuers) it is not possible
to locate and dig out all the buried subjects at the
same time. The question arises in which order the
buried subjects shall be rescued. Subjects with higher chances of survival should be located and dug
out first. Besides simple terrain factors, e.g. drop
over a cliff, the burial depth and vital data are an
important triage criteria.
7.4.2 Vital Data Detection
The PULSE Barryvox® contains highly sensitive sensors (g-sensor) that can detect slight motion of the
body, such as a pumping heart or breathing lungs.
Any motion within a certain maximum lag time is
interpreted as vital data. The buried subject belongs
to the category
with high chances of survival. It
can be assumed that buried subjects, which have
survived the first 35 min, are still able to breathe (air
pocket), and therefore have increased chances of
survival. At the same time, the detectability of vital
data decreases due to hypothermia. Therefore, buried
subjects who have transmitted vital data for the first
35 min are considered to belong to the category
with high chances of survival for the rest of their burial duration.
All the buried subjects, whose transceivers are
technically not capable of detecting vital data or
cannot detect any for whatever reason, belong to
the category
with unknown chances of survival.
The data are displayed on the buried subject’s transceiver and also sent across the W-Link radio connection to the transceivers of the rescuers. Based on the
list of buried subjects, the rescuer decides in which
order he or she will locate and dig them out. Using
vital data as a triage criteria shortens the burial duration for those subjects having
higher chances of
survival. This improves the overall rescue efficiency.
The vital data do not provide an assessment of
the health of the buried subject. They do not substitute an assessment by medically trained personnel (physician).
Only rescuers using a transceiver with a W-Link
radio connection are able to receive vital data.
The range of the W-Link depends on terrain and body
interference, on the physical characteristics of the
avalanche debris as well as on the orientation and
distance to the buried subject. The range of the WLink is therefore limited.
If you carry the transceiver in a trouser’s pocket,
the detection of vital data is not possible due to
the almost non-existent movements.
Companion Rescue
Pinpointing with Transceiver and Probe Pole
Pinpointing the location of a buried subject is not
possible with a transceiver alone. The burial depth
and the orientation of the subject can be determined
easily and quickly with a probe pole. Starting at the
point with the lowest distance reading or loudest
tone, apply a spiral search pattern. Always probe at a
right angle to the snow surface.
If the buried subject is hit with the probe pole, the
pole is left in the snow. It serves as a guide while
excavating the buried subject.
The burial depth is also a triage criterion. In situations with limited resources deep burials are located
Rescue – Excavating the Buried Subject
Size the area to be dug out generously. Pay attention
to the presence of an air pocket and avoid trampling
on top of the buried subject. Access the buried subject laterally. Digging must be practiced as well. It
takes by far the most time.
Cut out blocks of snow with the shovel. The lead shoveler of the group should be relieved from time to time.
Rotating clockwise at given intervals is easiest.
Companion Rescue
Burial and Vital Duration
In case of a burial, the transceiver records the burial
duration and detects vital data.
By pressing any key in the SEND mode, you can recall
the burial data of the five last resting periods of the
transceiver. The resting periods are numbered:
most recent resting period
second last resting period
third last resting period
fourth last resting period

The Barryvox automatically displays the burial duration
as soon as the transceiver stops being moved. The
burial duration is displayed in hours and minutes along
with the time during which vital data was detected.
The display of the burial duration is also activated, if
the Barryvox stops moving outside of an avalanche.
In multiple burial situations, the transceiver of a rescued subject should be turned off as soon as possible.
It is not possible to provide a complete list of all
mountain and helicopter rescue services in this
manual. Please inform yourself prior to your trip
about the local rescue services and their phone numbers and radio frequencies.

Introduction to Avalanche Theor y
Introduction to Avalanche Theory
We would like to provide you with some basics on
this complex topic and recommend thorough initial
and ongoing advanced avalanche training.
The Slab Avalanche: The Set Trap
Most winter outdoor travelers trigger their own avalanches. The snowpack is fragile. Slab avalanches
resemble set traps: If we trigger it, the trap snaps.
Remember that a small slab of 100 m3 weighs about
25 tons!
Hazard identification
Very critical weather situations
The avalanche danger increases rapidly after storms
with new snow, wind, and cold temperatures. Slopes
with wind-drifted snow are especially dangerous!
Snow can also be moved by wind during nice weather. The first nice day after a snow event is particularly
dangerous. Most accidents occur when a cold front
with strong winds and snow moves in after days of
blue skies and cold temperatures! In this situation,
new snow amounts of 10 – 20 cm can constitute a
critical situation that can last several days.
Rapid and strong warming (downslope wind, rain) can
also cause an increase in avalanche danger, which
decreases again with falling temperatures. If the
snowpack is uneven and weak, the danger is hard to
perceive. This is often the case with shallow snow
packs in the beginning of winter or during periods of
little precipitation. In spring, the danger usually
increases as the day progresses: from low in the
morning following a clear night to considerable in the
8. 2 Risk Assessment
Critical amounts of new snow
With the following amounts of new snowfall within
1 – 3 days, the danger level is at least
10–20 cm with adverse conditions
20–30 cm with average conditions
30–50 cm with favorable conditions
Humans as Trigger of the Trap
The steeper and more shaded the slope is, the
greater the likelihood of releasing a slab avalanche.
The likelihood increases with large groups without
spacing, frequent turns, and especially with falls or
jumps over cornices or other shock loading. Remote
triggering is possible starting with the danger level
CONSIDERABLE, i.e. the person triggering the avalanche can be standing dozens of meters outside of
the fracture zone. This is fatal at the bottom of a
slope, because the entire slope above can be
8.3.1 Standard Safety Precautions
Note: Light forest (with trees far apart enough to ski
or ride through) will not protect you from slab avalanches. Even rock outcroppings will not prevent the
release of slab avalanches.
The following standard safety precautions should
always be taken regardless of the danger level:
Avalanche transceiver on SEND,
along with a probe pole and shovel
Avoid fresh wind-deposited snow
Consider daily fluctuations in temperature,
especially in the spring
Constantly assess the conditions
throughout the trip
Adverse conditions
Strong wind (> 50 km/h)
Low temperatures (< -8° C)
Slope seldom traveled
Favorable conditions
Light wind
Temperatures little below 0° C
Slope traveled frequently
Introduction to Avalanche Theor y
8.3.2 Minimize Stress on the Snowpack
Adequate spacing is an effective method to minimize
stress on the snowpack. Ascending, the spacing
should be approximately 10 meters; descending
approximately 30 – 50 meters, due to the additional
stress. Danger zones should be traveled one person
at a time. Minimize the stress on the snowpack by
making long turns. Avoid jumping!
