What is role of avalanche beacons in multiple burial situations?

Locating Buried Individuals

In a multiple burial situation, avalanche beacons become essential tools for search and rescue teams. Each beacon emits a unique digital code, known as a “transponder code,” which allows the device to be identified on the receiving device, typically a digital probe or a probe with a transceiver. When a buried person activates their beacon, it begins transmitting their transponder code, helping rescuers pinpoint their location.

Separating Buried Individuals

The use of avalanche beacons in multiple burials involves a process called “pinging.” By setting the receiving device to the transponder code of the buried person, rescuers can detect the signal and move closer to the buried individual. This process is repeated until the team is within a few feet of the buried person. To separate the individuals, rescuers use a technique called “interferencing,” where they activate their own beacons and move around the buried person, causing their signal to interfere with the original signal. By analyzing the interference patterns, rescuers can determine the location of each buried person and begin excavation. In ideal conditions, this process can be completed within 10-15 minutes.

Maximizing Efficiency

To maximize efficiency in multiple burial situations, it’s essential to establish a clear communication plan and designate a lead rescuer to coordinate the search and rescue efforts. The team should also use a systematic search pattern, such as a grid search, to ensure thorough coverage of the area. Additionally, having multiple beacons and probes available can speed up the process and increase the chances of successful rescue.
