Congratulations on the purchase of your newELEMENT Barryvox®

This reference manual explains the functionality anduse of the ELEMENT Barryvox® .

A transceiver does not protect you against avalanches!

As a winter outdoor enthusiast, you must considerall possible avalanche prevention measures andplan your trips carefully. Companion rescue – theworst case – must be practiced frequently. Underthe stress of an accident, this is the only way youwill be able to locate and dig out a companionquickly and efficiently. Despite practice and all thetechnological advancements, by far not all of thecompletely buried avalanche victims are rescued!An avalanche burial is always life threatening.

Important information on these topics can be foundin the chapters on companion rescue and avalanchetheory.

2.4 Handling the Barryvox

As all transceivers, the Barryvox contains shock-sensitive ferrite antennas. Therefore, you shouldhandle it with utmost care!

Store the device and the carrying system in a dryspot that is protected from extreme cold or heatand direct sunshine.

It is recommended that you have the functionalitytested at regular intervals (see chapter «PeriodicChecks»).

2.5 Interferences

As a matter of principle, avoid having other elec-tronic devices (e.g. mobile phones, radios, head-lamps), metal objects (pocket knives, magnetic but-tons), or other transceivers close to (20 cm inSEND; 50 cm in SEARCH) your running avalanchetransceiver. Users of pacemakers are advised tocarry the device in a pant pocket, the zippermust remain closed for the duration of the trip(without vital data detection). Consult the manu-facturer’s instructions with regard to the impact onpacemakers.For professional and institutional use, it is highlyrecommended to consult the Barryvox ApplicationSafety Guide (www.mammut.ch/BarryvoxManual).

When searching, hold the device at a minimum of50cm away from these objects and turn off anyelectronic devices, if possible. Be aware that electronic devices used by other res-cuers may disturb the search. This is equally validfor mobile phones, therefore it is highly recommen-ded to switch off phones which are not absolutelyrequired.

The Application Safety Guide of the Barryvox con-tains an exhaustive list of allowed equipment aswell as a detailed list of possible limitations.(www.mammut.ch/BarryvoxManual)

SETUP

2. Setup

2.1 Initial Setup

Before you use the device for the first time, removethe protective foil on the front side and stick theemergency plan on the back of the battery com-partment lid.

2.2 Insert / Replace Batteries

Only use alkaline (LR03/AAA) batteries of the sametype. Always insert 3 new batteries of the sametype. In case these batteries need to be removed,the same 3 batteries or 3 new batteries need to bereinserted. Never use rechargeable batteries andalways replace all the batteries at the same time.

Make sure the lid is properly closed and that thedevice and the batteries stay dry. Periodicallyinspect the battery compartment. Clean or dry it, ifneeded, since moisture can cause corrosion. Avoidtouching the contacts with your hands.

A reliable power supply is crucial for the safe oper-ation. Please refer to the detailed instructions in theApplication Safety Guide.(www.mammut.ch/BarryvoxManual)

2.2.1 Important Points When Using Alkaline Batteries Type LR03/AAA

When storing or not using the transceiver for anextended period of time (i.e. in the summer),remove the batteries and leave the battery com-partment open. The warranty becomes void if bat-teries have leaked! When reinserting the batteries,use the same 3 batteries or 3 new batteries.

2.3 Adjusting the carrying system

Adjust the carrying system to fit your body. (Chapter «Carrying positions»).

Setup

2.7 Turning the Device On

When the main switch is moved from the OFF to theSEND or SEARCH positions, the transceiver is turnedon. To slide the main switch from OFF to SEND orSEARCH, unlock the main switch by pressing down thebutton at the top. While starting, the device conducts a self-test.The microprocessor, the antennas and the displayare checked.If the self-test is completed successfully, the dis-play will show «OK».

The remaining battery level is displayed as a percent-age.If the self-test fails, an error message is displayedfor 20 seconds along with an acoustic warning.The meanings of the different error messages aredescribed in the chapter «Troubleshooting».

Test your Barryvox at home prior to your trip. Turnthe transceiver on and monitor the self-test and thebattery level. This gives you the opportunity toreplace low batteries and have an eventual defectrepaired beforehand.

2.8 Battery Level Indicator

The following table gives you average values for thebattery levels.The remaining battery level can only be displayedcorrectly if batteries are used according to thechapter «Insert / Replace Batteries». Low tempera-tures, age, and brand can have a negative impacton the battery life and the accuracy of the batterylevel indication.

100%: Normative Requirement (=minimum requirement) min 200hrs SEND at 10°C followed by 1hr SEARCH at -10°C

Typical values for the ELEMENT Barryvox® with alkaline batteries: 250hrs SEND at 10°C Measured with Duracell ULTRA (initial set of batteries)

less than The batteries must be 20% replaced as soon asor 0% possible! Emergency reserve at 20%: Max. 20hrs in SEND mode and max. 1 hr in SEARCH mode left.

The transceiver sounds a warning if the batterylevel is below 20% or unknown at startup.

SETUP

2.6 Carrying Positions

Regardless of the carrying position, the displayshould always face your body!

2.6.1 Carrying System (Recommended Carrying Position)

The carrying system has to be put on your inner-most layer of clothing prior to beginning the trip(see illustration) and has to be worn on your bodyfor the duration of the trip. The transceiver shallalways remain covered by one layer of clothing.The device itself is inserted into the carrying sys-tem according to the illustration. It should alwaysremain anchored to the base plate of the carryingsystem using the red hook on the wrist loop.

2.6.2 Carrying the Transceiver in a Pocket

If you carry the Barryvoxin a pant pocket, the zip-per must remain closedfor the duration of the trip.Always use a securedpocket (see illustration). Ifpossible, attach the wristloop to your pants orsecure it around your belt.

Double Group Check

We recommend to perform a double group checkones a week and in general when a new group getstogether.The double group check individually tests the SENDand SEARCH function of all devices.The members of the party activate the group checkon their transceivers or set them to a low receivevolume. The leader switches his or her transceiverto the SEND mode and ensures that all party mem-bers can receive. Subsequently, the party membersswitch their transceivers to SEND, and the leaderactivates the group check or sets the transceiver toa low receive volume. The SEND mode of all trans-ceivers is checked, and ultimately the leaderswitches his or her transceiver to SEND.

MEMBERSLEADER

SETUP

2.9 Group Check

Single Group CheckBefore a party takes off, the transceivers of all partymembers must be checked. To conduct this test,the function group check is activated on a singletransceiver within the party. Activate the groupcheck by switching the device from OFF to SENDand pressing either of the keys within the first 5seconds. After a few seconds, the device will auto-matically activate the group check. Make sure allthe other transceivers of the party are in SENDmode.The test is successful if you can clearly hear beepsounds from each participant's transceiver withinthe range indicated on the display. The members ofthe party must be spread out appropriately to avoidmutual interference. The indicated test distancemust not be shortened, as otherwise the groupcheck becomes very unreliable. If no tone is heard within the indicated range,the device may not be used.

How to solve the problem:

1.Check if the device is switched to SEND.

2.Replace the batteries.

3.Have the device checked by the manufacturer. (chapter «Maintenance and Repair»)

After 5 minutes in group check, the transceiverautomatically switches to the SEND mode. The useris warned ahead of time by an acoustic alarm. Thisautomatic switching can be prevented by pressingany button within 20 seconds. After the groupcheck, the transceiver must be switched to theSEND mode by pressing the lateral key.

If your ELEMENT Barryvox® detects that the trans-mit frequency of the tested device is not within thenormative regulations, an «E6» warning messagewill be shown. In this case, repeat the test with 5mdistance between the participants to identify thedefective transmitter. Such devices must bechecked/repaired by the manufacturer.

4.1 Search Phases

In an avalanche search, the following phases aredistinguished:

l Signal searchl Coarse searchl Fine searchl Pinpointing

Signal search:

Search area to the pointwhere the first signal canbe detected.

Coarse search:

Search area starting fromthe reception of the firstsignal until the immediatevicinity of the buried sub-ject. In this phase the signalsearch pattern is abandonedin order to follow the sig-nals leading to the buriedsubject.

Fine search:

Search area in the immedi-ate vicinity of the buriedsubject.

Pinpointing:

First use of the probe untilprobe hit.

using transceiver

using probe

4. SEARCH Mode

Although the avalanche transceiver is easy touse, its effective use requires proper training.We recommend that you practice transceiversearches regularly.Electronic devices and metal objects can inter-fere with the search or make it impossible.See chapter «Interferences».

Be aware that electronic devices used by other res-cuers may disturb the search. This is equally validfor mobile phones, therefore it is highly recommen-ded to switch off phones with are not absolutelyrequired.

At the beginning and during the search, pay closeattention that the rescuer’s transceivers are nottransmitting and do not switch to SEND unintentio-nally.

It does not make sense to remove the backpack andmount the shovel and probe already at the boarderof the avalanche. Keep the backpack with all theequipment on you! The assembled shovel and probeis only a hindrance during signal and coursesearch. Only remove your pack to assemble probeand shovel ones you have successfully concludedthe fine search.

SEND MODE

3. SEND Mode

The SEND mode is the normal operating mode out-doors or in all other situations in which there is arisk of avalanches.Each time the SEND mode has been activated, thisis confirmed by a triple beep sound.Each individual signal element is tested. If the testis successful, this is confirmed by a blink of the redSEND-Control LED. The LCD display is automatically deactivated in theSEND mode, but can be activated any time by pres-sing either of the keys.

4.2 Auto-Revert to SEND

Auto-revert to SEND automatically switches thetransceiver from the SEARCH mode to the SENDmode if no user interaction occurs during 8 min-utes. Prior to reverting, the device will sound an audiblealarm. Reverting can be avoided if either of thekeys is pressed within 30 seconds of the alarm.

In case rescuers are buried in a second avalanche,this function allows them to be located using trans-ceivers.

Elementary understanding of transceiver search

The 457kHz transmitter of the transceiver has a spa-cial, kidney shaped transmit distribution, which isvisualized with field lines in the illustration below.The searching transceiver leads the rescuer alongthe field lines and therefore usually not in a straightline to the buried subject.

Search Along the Field Line: Flux line search

SEARCH MODE

4.1.1 Signal Search

From the start of the search until you hear the firsttone, you are in signal search. The avalanche surface is searched systematicallyuntil you pick up a signal. During the acoustic sig-nal search, the rescuer has the visual focus on thesurface of the debris in order to be able to see bodyparts or objects protruding the snow surface.

The ELEMENT Barryvox® uses the symbol asa generic instruction to apply one of the follow-ing search patterns for new signals!

Optimization of Range

To optimize the range, rotate the transceiver slowlyaround all axes. Hold the device with the loudspeakerfacing your ear sidewise of your head.

If your Barryvox® detects that the signal searchstrip width needs to be reduced due to a devicetransmitting far apart from the normative regula-tion, the reduced search strip width will be indicat-ed.

Regardless of the operating mode, the followingsearch strategies apply:

Search strategy if the last seen point is unknown.

4.3.1 Search for a Single Buried Subject Using the Search Mode

Coarse Search

If the distance to the buried subject is less thanapprox. 60 meters, the distance and direction aredisplayed.

Interpretation of the Distance Indication

The distance indication shows the longest possibledistance to the buried subject in meters. The buriedsubject may be much closer, but never ever furtherapart from the rescuer. The distance can never be determined exactly. It isimportant whether the numbers are increasing ordecreasing. The closer you are to the transmittingdevice, the more precise the indicated distance is.

Practical Search Instructions

Hold the transceiver horizontally in front of youand proceed in the direction indicated by thearrow. If the distance increases, you are movingaway from the victim. Continue the search in theopposite direction. The transceiver will lead you tothe buried subject quickly and reliably. Do not move backwards, otherwise the directionindication will be incorrect.Start the search at a high speed and reduce yourspeed as you close in on the buried subject. Oper-ate the transceiver in a quiet and concentratedmanner - avoid rapid movements. This way, you willreach the objective in the quickest and easiestmanner!

2928

Deep Burials

Marking a buried subject in more than 3 metersdepth is not possible. For further information,please see chapter «No Probe Hit».

SEARCH MODE

Fine search

During fine search hold the transceiver directlyabove the snow surface! Proceed in a straightline until you reach the point of the smallestdistance reading and use the shovel to markthis spot as a visual reference for the probingspiral.

Use the avalanche probe to complete locating theburied subject (See chapter «Companion Rescue»).

A located subject should only be marked using the 3-Mark function after his or her location has beenverified using a probe pole! Do not place the Bar-ryvox on the snow surface again for this purpose!

After marking a subject’s location, the Barryvoxsearches for other possible burials. The transceiverleads you directly to the next buried subject or thesignal search symbol is displayed and advisingyou to search the rest of the avalanche (See chap-ter «Signal Search»).

Procedure for multiple burialsProcedure

1. The device favorsthe closest subjectfirst. Locate the vari-ous buried subjectsusing the transceiverand probe pole(Chapter «Search fora Single Buried Sub-ject using the SearchMode»).

2. As soon as you markan individual subject,the transceiver takesyou to the nearest,unmarked buriedsubject.

3. Continue this proce-dure until all sub-jects are located andmarked.

4. The rescuer nowsearches for addi-tional buried sub-jects while the dis-play shows the sym-bol for the signalsearch phase toindicate that the restof the avalanche sur-face must besearched (Chapter«Signal Search»).

SEARCH MODE

4.3.2 Search for Multiple Buried Subjects Using the Search Mode

In search mode, the transceiver attempts to analyzeall the detectable signals and to determine the num-ber of buried subjects. This is possible, because allthe signals from one transmitter display characteris-tics, which are distinguishable from the signals fromother transmitters. The more unique the signal char-acteristics are, the more accurately the signals canbe distinguished and located (pattern recognition).By automatically associating the signals with theirrespective sources, multiple burial situations can besolved without applying specific search tactics.Transceivers which additionally transmit W-Linkinformation can be detected particularly fast andreliable.

List of Buried Subjects

The buried subjects whose transmit patterns can beidentified are inserted in the list of buried subjectsbased on their signal strength. The closest buriedsubject on the avalanche is shown at the bottom, thefurthest at the top of the list.

The list of buried subjects can show no more than 3 buried subjects at the time. In case the amount ofrecognized buried subjects is greater, arrow symbolsindicate that the list contains further down or furtherup in the list additional entries. Usually, the deviceguides you so that the list is processed from bottomto top. The lower, already hidden part of the list ofburied subjects (symbol ). contains thereforethe buried subjects which have already been markedas found, and the upper, not yet visible part of thelist (symbol ), the buried subjects which arenot found yet and still ahead of you on the avalan-che. Independently of the position of a buried subjectin the list, the device will always try to guide you asquickly as possible until all recognized buried sub-jects are found.

3332

4.3.3 Limitations

The larger the number of buried subjects, the moredifficult and time-consuming the exact analysis ofthe situation gets, because of overlapping signals.The more signals there are, the longer the signaloverlaps can last. The capability to automaticallydetect and isolate signals from multiple buried sub-jects is therefore limited.

+Symbol

The +symbol indicates that signals are received fromadditional buried subjects that cannot be isolatedand entered in the list of buried subjects yet. Turn offthe transceivers of the buried subjects already foundas soon as possible to simplify the isolation of theremaining signals.

Search Suspension / “Stand still!”

During the search for multiple subjects, signals mayoverlap making it impossible to analyze the signalof a single buried subject. If the signal overlap lastsseveral seconds, the rescuer has to interrupt theprocess temporarily to avoid deviating from theoptimal search path. The Barryvox® will indicatethe necessity to suspend (max. 15 seconds) thesearch by displaying the word «Stop». Stand still,and do not move until the word «Stop» disappears,at which time you can continue to search.

SEARCH MODE

Search With Multiple Rescuers

When the search is conducted with multiple res-cues searching at the same time, it should beavoided that several rescuers search for the sameburied subject.

Situation 1: Two rescuers receive two buried sub-jects. One rescuer continues the search for theburied subject closest to him, the other rescuershould directly search for the second buried sub-ject, without having to mark the first one. Thesearch is therefore continued on the current signalsearch pattern until the transceiver obviously leadsto a different buried subject.

Situation 2: The two rescuers only receive oneburied subject. One rescuer continues the searchfor the buried subject closest to him, the other res-cuer should search the remaining of the avalanchefor more buried subjects. The search is thereforecontinued on the current signal search pattern untilthe transceiver obviously leads to a different buriedsubject.

5.5 Periodic check by a Barryvox Service Point

To check the proper function of the device, is highlyrecommended to send the device every 3 years, orwhen reaching 3000 hours of operation, to a Barry-vox service center or have it checked by a Barryvoxservice point (service charge will apply).The functional test is much more comprehensiveand precise than the self and group check. As partof this service the electronics and the mechanicalcomponents such as the case, the main switch andthe lateral key, the battery contacts, the batterycompartment and cover as well as the wrist strapwill be checked. In case the check shows abnormalwear and tear due to incorrect or long, very intenseuse, the service center may recommend you to pur-chase an exchange device.

We recommend that you have your device checkedduring the summer months so that your Barryvox istested and ready to use at the start of the next win-ter season. In the “Maintenance” tab in the startmenu, you can see when the next check is due.

For further information concerning maintenanceand testing of Barryvox transceivers, please consultthe Barryvox Application Safety Guide. (www.mammut.ch/BarryvoxManual)

3534

5.4 Frequent, self-responsible check

Always check the result of the self- and battery test(chapter “Turning the Device On” and “Battery LevelIndicator”) and pay attention to alert messages(chapter “Troubleshooting”). Regularly carry out thegroup checks as indicated in chapter “GroupCheck”. Furthermore, we recommend that you takeself-responsibility by frequently checking your devi-ce for mechanical damage of the casing, properfunction of the main switch, battery compartmentcover as well as cleanness of the battery contacts.In case you detect problems, it is mandatory tohave the device checked by one of the service cen-ters listed under “Registration and Service”

COMPANION RESCUE

6. Companion Rescue

Companion rescue means that buried subjects arelocated and excavated by members of their partyimmediately after the avalanche slide. Avalancherescue is a race against time! While most buriedsubjects can be rescued within the first 8 minutes,the chances of survival decrease rapidly after-wards. Companion rescue, therefore, provides thegreatest chances of survival for a buried subject.

6.1 If an Avalanche Occurs

As a Victim:

• Escape to the side• Discard skis, snowboards, and poles ➜ anchor effect• Try to stay on top• Close your mouth; place your hands in front of your face ➜ clear airway when the avalanche stops

Separate instructions apply for the use of special-ized safety equipment, such as the highly efficientflotation devices.

As a Witness:

• Memorize the last seen point as well as the direction of the avalanche ➜ primary search strip (See chapter «Signal Search»).

6.2 Personal Rescue Equipment

Carrying the proper personal safety equipment iscritical for effective companion rescue. A transceiv-er, a shovel, and a probe pole are necessary tolocalize and excavate a buried subject quickly andefficiently.Mammut offers a variety of suitable probe polesand shovels.

The use of a flotation device (airbag system) signifi-cantly reduces the risk to be completely buried andtherefore leads to considerably higher survivalchances.

Carrying a radio or a mobile phone to call for help ishighly recommended.

The use of the transceiver precedes the use of theprobe pole and the use of the probe pole precedes theuse of the shovel.

6.5.1 Multiple Rescuers in the Fine- and Pinpoint Search

If several rescuers are present while you are in thefine or pinpoint search phase, place a probe 1 meterbelow the expected burial location. Now, you havethe required space to conclude the fine and pinpointsearch while the remaining rescuers already startwith the excavation of the buried subject. When youhave confirmed the find with a probe hit, removethe pilot probe so that the V-shaped snow conveyorbelt can be extended.

6.5.2 No Probe Hit

If the buried subject cannot be found by the probe,place the probe approx. 1 meter above the pointwith the lowest distance indication. While digging,enough space is now made available to allow a fur-ther fine and pinpoint search within the excavationsite.

COMPANION RESCUE

6.4 Triage Criteria and Vital Data

6.4.1 Triage

With limited resources (few rescuers) it is not possi-ble to locate and dig out all the buried subjects atthe same time. The question arises in which orderthe buried subjects shall be rescued. Subjects withhigher chances of survival should be located anddug out first. Besides simple terrain factors, e.g.drop over a cliff, in seracs or crevasses, collisionwith trees etc., the burial depth is an importanttriage criteria.

6.5 Pinpointing with Transceiver and Probe Pole

Pinpointing the location of a buried subject is notpossible with a transceiver alone. The burial depthand the orientation of the subject can be deter-mined easily and quickly with a probe pole. Use theshovel to mark the point with the lowest distancereading or loudest tone as a visual reference for theprobing spiral. Always probe at a right angle to thesnow surface. If the buried subject is hit with the probe pole, thepole is left in the snow. It serves as a guide whileexcavating the buried subject.The burial depth is also a triage criterion. In situa-tions with limited resources deep burials are locat-ed later.

C CirculationPerform CPR as necessary

Basic Life Support

➜ Depending on ABCs, continue rescue breathsor CPR on patient.

➜ For a patient in an avalanche accident, spe-cial attention need to be paid to the imme-diate clearance of the airway and rescuebreaths.

➜ Prevent further heat loss.

➜ If patient is responsive and can control his/herairway, administer warm fluids

➜ Handle patient very gently.

➜ Evacuate by helicopter whenever possible.

6.6 Rescue – Excavating the Buried Subject

Size the area to be dug out generously. Pay atten-tion to the presence of an air pocket and avoidtrampling on top of the buried subject. Access theburied subject laterally. Digging must be practicedas well. It takes by far the most time.

The V-Shaped Snow Conveyor Belt

➜ Position diggers in a «V» formation

➜ The first two rescuers are in a distance of oneshovel length from each other, all additionalrescuers are in a distance of two shovel lengthfrom each other.

➜ Length of «V»:• Flat terrain: 2x burial depth• Steep terrain: 1x burial depth

➜ Amount of rescuers: 1 per 80 cm length of «V»

➜ Rescuer in the tip of the “V” directly digs fol-lowing the probe to the buried subject

➜ Diggers rotate frequently (approx. every 4 min)clockwise on command of the rescue at the tipof the «V»

➜ Cut out blocks of snow with the shovel by step-ping on the shovel blade which is held perpen-dicular to the surface. Apply a half-moonshaped cutting pattern. Position yourself facingthe open end of the “V”, cut the first half-moonwithout pulling back on the shovel shaft. Whencutting the second and subsequent half-moons,pull the shovel shaft gently backwards after youhave cut the block so that it pops out. To cut thenext half-moon, step backwards toward theprobe, like this, you do not step on the pre-cutblocks.

7. 2 Risk Assessment

Critical amounts of new snowWith the following amounts of new snowfall within1 – 3 days, the danger level is at least CONSIDERABLE:10–20 cm with adverse conditions20–30 cm with average conditions30–50 cm with favorable conditions

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

Humans as Trigger of the Trap

The steeper and more shaded the slope is, thegreater the likelihood of releasing a slab avalanche.The likelihood increases with large groups withoutspacing, frequent turns, and especially with falls orjumps over cornices or other shock loading. Remotetriggering is possible starting with the danger levelCONSIDERABLE, i.e. the person triggering the ava-lanche can be standing dozens of meters outside ofthe fracture zone. This is fatal at the bottom of aslope, because the entire slope above can bereleased!

Note: Light forest (trees far enough apart to ski orride through) will not protect you from slab ava-lanches. Even rock outcroppings will not preventthe release of slab avalanches.

7.3 Precautions

7.3.1 Standard Safety Precautions

The following standard safety precautions shouldalways 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

Pay attention to avalanche hazard even duringthe summer, in particular after recent snowfall.Apply the safety precautions if required.

INTRODUCTION TO AVALANCHE THEORY

7. Introduction to Avalanche Theory

We would like to provide you with some basics onthis complex topic and recommend thorough initialand ongoing advanced avalanche training.

The Slab Avalanche: The Set Trap

Most winter outdoor travelers trigger their own ava-lanches. The snowpack is fragile. Slab avalanchesresemble set traps: If we trigger it, the trap snaps.Remember that a small slab of 100m3 weighs about25 tons!

7.1 Hazard identification

Very critical weather situations

The avalanche danger increases rapidly afterstorms with new snow, wind, and cold tempera-tures. Slopes with wind-drifted snow are especiallydangerous! Snow can also be moved by wind dur-ing nice weather. The first nice day after a snowevent is particularly dangerous. Most accidentsoccur when a cold front with strong winds andsnow moves in after days of blue skies and coldtemperatures! In this situation, new snow amountsof 10 – 20 cm can constitute a critical situation thatcan last several days.

Rapid and strong warming (downslope wind, rain)can also cause an increase in avalanche danger,which decreases again with falling temperatures. Ifthe snowpack is uneven and weak, the danger ishard to perceive. This is often the case with shallowsnow packs in the beginning of winter or duringperiods of little precipitation. In spring, the dangerusually increases as the day progresses: from lowin the morning following a clear night to consider-able in the afternoon.

INTRODUCTION TO AVALANCHE THEORY

7.3.2 Minimize Stress on the Snowpack

Adequate spacing is an effective method to mini-mize stress on the snowpack. Ascending, the spac-ing should be approximately 10 meters; descendingapproximately 30 – 50 meters, due to the additionalstress. Danger zones should be traveled one personat a time. Minimize the stress on the snowpack bymaking long turns. Avoid jumping!

7.3.3 Renunciation in the Terrain (Basic Reduction Method, W. Munter)

Danger Level Skiable/ridable slope angle2-Moderate less than 40 degrees3-Considerable less than 35 degrees4-High less than 30 degrees

• Untracked steep slopes (> 30 degrees): ➜ spacing of at least 10 m.• Outside of the forecasted aspect or altitude ranges: ➜ the danger level is generally one level lower.• At the edge of the forecasted aspect or altitude ranges: ➜ Do not approach the limits
