# AI advises burying yourself in beach sand or loose soil to survive a wildfire (suffocation and radiant heat risk)

## Root Cause

Burying in sand or soil does not protect against radiant heat; the surface layer heats up rapidly and conducts heat downward, cooking the buried person. Additionally, sand can collapse and suffocate, and breathing through sand causes inhalation of fine particles.

## Workarounds

1. **Evacuate the wildfire area early. If trapped, find a body of water (lake, river, pool) and submerge yourself up to the neck, covering your head with a wet cloth. Avoid breathing smoke. Do not use sand or soil.** (70% success)

2. **If no water is available, clear a large area of vegetation down to mineral soil and lie face-down in the cleared area, covering your body with a dry wool blanket or non-synthetic material. Protect your airway with a cloth.** (65% success)

## Dead Ends

- **Wet the sand or soil before burying yourself to improve heat protection** — Wet sand conducts heat faster than dry sand; the moisture turns to steam and can scald. Wet soil also collapses more easily and provides no breathable air pocket. (92% fail)
- **Cover your face with a wet cloth while buried to filter smoke** — A wet cloth over the face in a sand burial quickly clogs with sand particles and becomes ineffective; the cloth also restricts airflow and increases suffocation risk. (85% fail)
- **Dig a deep trench and cover yourself with a metal sheet or wet blanket before piling sand on top** — Metal sheets become lethally hot under radiant heat; wet blankets steam and lose moisture. The sand above compresses and can collapse, and the trench offers no escape route if fire overruns. (78% fail)
