ASC Rescue Techniques & Emergency Response 1 — Questions and Answers
Question 1: What is the first priority in an avalanche rescue?
- Dig a trench
- Call for backup
- Check for hypothermia
- Ensure scene safety (Correct answer)
Correct answer: Ensure scene safety
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?
- Snow probe
- Shovel
- Transceiver (Correct answer)
- Whistle
Correct answer: Transceiver
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?
- 0.2 meters
- 0.5 meters
- 1.2 meters (Correct answer)
- 2.5 meters
Correct answer: 1.2 meters
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?
- To avoid cold injury
- To prevent equipment loss
- Because of weather changes
- Due to rapid decrease in survival rates (Correct answer)
Correct answer: Due to rapid decrease in survival rates
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?
- Visual scanning
- Calling out
- Transceiver sweep
- Probing grid pattern (Correct answer)
Correct answer: Probing grid pattern
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.
Question 6: What is the role of a rescue shovel?
- Cutting snow blocks
- Digging victims out (Correct answer)
- Climbing assistance
- Building snow shelters
Correct answer: Digging victims out
A rescue shovel is an indispensable tool in avalanche rescue, primarily used for efficiently digging out buried victims. Its robust construction and ergonomic design allow rescuers to move large amounts of dense avalanche debris quickly, which is crucial for timely extraction.
Question 7: What does the acronym ABC stand for in emergency care?
- Alert, Breathe, Control
- Activate, Balance, Check
- Airway, Breathing, Circulation (Correct answer)
- Assist, Backup, Care
Correct answer: Airway, Breathing, Circulation
In emergency care, ABC stands for Airway, Breathing, and Circulation, representing the critical sequence of priorities for assessing and managing a patient's life-threatening conditions. Establishing a clear airway, ensuring adequate breathing, and maintaining circulation are fundamental steps to preserve life.
Question 8: Why are rescue simulations important?
- Boost confidence
- Improve fitness
- Enhance gear durability
- Train for effective response (Correct answer)
Correct answer: Train for effective response
Rescue simulations are vital for training avalanche professionals and recreationalists to respond effectively and efficiently during a real avalanche incident. Regular practice helps individuals refine their search and rescue skills, improve teamwork, and build muscle memory for critical actions under pressure.
Question 9: What is the function of a RECCO reflector?
- Detects heart rate
- Enhances vision
- Reflects radar signals for search (Correct answer)
- Warms the body
Correct answer: Reflects radar signals for search
A RECCO reflector is a small, passive electronic transponder integrated into clothing or gear that reflects radar signals emitted by a RECCO detector used by organized rescue teams. It provides an additional method for professional rescuers to quickly locate buried individuals, complementing transceiver searches.
