ASC Safety Equipment Usage & Risk Management

Question 1

What is the main use of an avalanche beacon?

Accepted Answer

Transmit rescue signals

Answer

An avalanche beacon is a critical piece of safety equipment designed to transmit and receive radio signals. Its primary use is to help locate buried victims in an avalanche by emitting a signal that can be picked up by other beacons in search mode. This significantly speeds up rescue efforts, which is crucial for survival.

Question 2

What safety gear helps prevent deep burial in an avalanche?

Accepted Answer

Avalanche airbag

Answer

An avalanche airbag is designed to prevent deep burial during an avalanche. When deployed, it inflates a large bag that increases the victim's volume, making them more buoyant in the moving snow. This helps the person stay on or near the surface of the avalanche debris, greatly increasing their chances of survival and making them easier to locate.

Question 3

Which is a key component of avalanche risk assessment?

Accepted Answer

Risk triangle: terrain, snowpack, weather

Answer

Avalanche risk assessment relies on evaluating the "risk triangle," which comprises three interconnected factors: terrain, snowpack, and weather. Terrain considers slope angle and aspect, snowpack refers to the layers and stability of the snow, and weather includes recent snowfall, temperature, and wind. Analyzing these elements together provides a comprehensive understanding of avalanche danger.

Question 4

Why is carrying a probe essential?

Accepted Answer

To find victims’ depth

Answer

Carrying an avalanche probe is essential for locating buried avalanche victims once a beacon signal has narrowed down the search area. The probe is a collapsible pole used to systematically search the snow for the victim's body. It helps rescuers determine the exact location and depth of the buried person, guiding the precise spot for shoveling.

Question 5

How often should avalanche gear be tested?

Accepted Answer

Before every trip

Answer

Avalanche safety gear, especially beacons, should be tested before every trip into avalanche terrain. This ensures that batteries are charged, devices are functioning correctly, and users are familiar with their operation. Regular testing guarantees the reliability of the equipment when it's most critically needed, maximizing safety and preparedness.
