Quick Answer
To properly extinguish a fire built in snow, first smother it by covering the flames with snow, then ensure the snow is deep enough to cool the embers. Use 2-3 inches of snow to smother the fire, and 6-8 inches to cool the embers. Verify the fire is fully extinguished before leaving.
Smothering the Fire
To smother a fire built in snow, cover the flames with 2-3 inches of fresh, dry snow. This will deprive the fire of oxygen and cause it to suffocate. Use a shovel or your hands to gently press the snow onto the fire, making sure to cover all areas. Continue to add snow until the flames are extinguished.
Cooling the Embers
Once the fire is smothered, use 6-8 inches of snow to cool the embers. This is crucial to prevent re-ignition. The snow will help to lower the temperature of the embers, making it difficult for the fire to start again. Check the embers every few minutes to ensure they are cool to the touch.
Final Verification
After smothering and cooling the embers, verify that the fire is fully extinguished. Check for any remaining heat or sparks by placing your hand close to the area. If you still feel heat, continue to add snow until the area is cool to the touch. Only then can you be certain that the fire is fully extinguished and safe.
