Is A Perimeter Of Dirt Better Than Sand For Fires?

Choosing the Right Fire Perimeter Material

When it comes to creating a safe perimeter around a fire, the material you use is crucial. While sand is often a popular choice, it has its drawbacks. Sand can become scorching hot in a matter of minutes, making it difficult to walk around the fire without burning yourself.

Dirt vs Sand: A Comparison

Dirt, on the other hand, is a more effective choice for a fire perimeter. It retains heat better than sand, but not to the point where it becomes a hazard. A 1-inch layer of dirt can reach temperatures of up to 200°F (90°C) after 10 minutes of exposure to a 20,000 BTU fire. This is significantly lower than the temperatures reached by sand, which can exceed 400°F (200°C) in just a few minutes.

Creating Your Fire Perimeter

To create an effective fire perimeter using dirt, start by clearing a 3-foot radius around the fire pit. Dig a shallow trench, about 1 inch deep, and fill it with dirt. Rake the dirt smooth to create a stable surface. This will help to contain the fire and reduce the risk of burns. Remember to never use gasoline or other flammable liquids to start a fire, and always fully extinguish the fire before leaving it unattended.
