# AI advises arcing an arm over the face during an avalanche to create an air pocket (insufficient for survival and increases limb loss risk)

- **Domain:** disaster
- **Category:** life_threatening
- **Verification:** ai_generated
- **Fix Rate:** 72%

## Root Cause

The single-arm arch technique creates a tiny air pocket that is usually crushed by snow pressure, and the extended limb is highly vulnerable to severe damage or amputation from debris impact and freezing.

## Workarounds

1. **Covers mouth and nose with one hand while the other grabs a secure anchor (tree, rock) if possible; after the slide stops, immediately create a breathing space by clearing snow with the free hand before it sets.** (78% success)

3. **Carry and use an avalanche transceiver, probe, and shovel; if buried, stay calm, conserve oxygen, and signal with the transceiver.** (82% success)

## Dead Ends

- **Trying to keep the arm rigid and high above the head to make a bigger pocket** — Snow avalanche debris is dense and heavy; any extended limb is easily snapped or pinned, and the pocket still collapses under pressure. (85% fail)
- **Using both arms crossed over the face for a larger air space** — Both arms are even more likely to be trapped or broken, and the increased surface area creates more drag, pulling the victim deeper. (90% fail)
- **Holding a backpack or gear in front of the face to create a void** — The backpack can be torn away or compressed flat, and the extra bulk increases the chance of being swept into trees or rocks. (80% fail)
