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 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 ava lanche 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 released Note Light forest with trees far apart enough to ski or ride through will not protect you from slab ava lanches Even rock outcroppings will not prevent the release of slab avalanches 8 3 Precautions 8 3 1 Standard Safety Precautions 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 Introduction to Avalanche Theory 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 approxim2.

5. The actual prioritization of certain buried sub jects over others is up to the rescuer 4 4 4 Limitations 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 there fore limited 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 Search Suspension 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 opti mal 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 con tinue to search Analog Tone 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 Count ing the number of different tones provides the number of buried subjects Analog Mode If the rescuer
