Show The primary search area is not always only one section of the avalanche. We may be dealing with several and sometimes unconnected avalanche sections. This is especially true in the case of large avalanches and several victims. In this case, the prevailing situation dictates in which section and in which sequence the search should be started ( number of helpers and dogs). Example 1. A snow slab avalanche; smooth flow in the direction of descent; accumulation only in the deposition zone, and this only weakly at the edges; the victim last seen in the center of the avalanche: 1 - urgent search area « edges of deposition zone. Example 2. A snow slab avalanche, the flow of which passes an obstacle and therefore divides and comes to a stop in two separate cones. Nothing is known about the burial situation: 3 urgent search areas : 2 in the avalanche cone 1 at the obstacle. The secondary search area. The secondary search area is the one in which, according to the best judgment, the point of location cannot be plotted, or where certain special, rare and exceptional circumstances have played a part in the accident. Examples: 1. The victim has worked his way out of the line of flow by means of swimming movements and has been deposited at an unlikely spot. 2. An avalanche directly following ( after- avalanche) has pushed the victim from his previous sliding course. 3. The victim has been thrown out of the avalanche. 4. The victim was able to free himself and collapsed ouvside of the avalanche• 5. Completely false information by witnesses which forced the rescue workers to search in a definite, meaningless area of the avalanche. Note: Every search has always to begin in the urgent search area and should " be concentrated there. The concentrated, immediate search in the urgent search area is always correct, ttcause, according to the best judgment, that is where the point - 36 - |
