ASC Rescue Techniques & Emergency Response

Question 1

What is the first priority in an avalanche rescue?

Accepted Answer

Ensure scene safety

Answer

The first priority in any avalanche rescue, like any emergency situation, is to ensure scene safety for rescuers. Entering an unsafe area could lead to further avalanches or injuries, jeopardizing the rescue effort and putting more lives at risk.

Question 2

Which tool is used to locate avalanche victims?

Accepted Answer

Transceiver

Answer

An avalanche transceiver (also known as a beacon) is the primary electronic tool used to locate avalanche victims. It transmits a radio signal when in send mode and receives signals when in search mode, allowing rescuers to pinpoint the buried victim's location.

Question 3

How deep can avalanche victims be buried on average?

Accepted Answer

1.2 meters

Answer

While burial depths vary greatly, studies and statistics indicate that the average depth of burial for avalanche victims is approximately 1.2 meters (about 4 feet). This depth highlights the critical need for avalanche probes and shovels in rescue efforts.

Question 4

Why is time critical during avalanche rescues?

Accepted Answer

Due to rapid decrease in survival rates

Answer

Time is extremely critical during avalanche rescues because survival rates decrease dramatically after the first 15-20 minutes of burial. Victims buried longer face increased risks of suffocation, trauma, and hypothermia, making a rapid and efficient rescue paramount.

Question 5

Which method is used to pinpoint victim location?

Accepted Answer

Probing grid pattern

Answer

After using a transceiver to get a coarse location, a probing grid pattern is used to pinpoint the exact location of a buried victim. Rescuers systematically probe the snow with an avalanche probe in a grid, increasing the chances of striking the victim and allowing for precise digging.
