Even when cool to the touch, coals and ashes can hold enough heat in their cores to ignite combustibles under the right conditions. To be safe, simply treat all coals and ashes as if they are hot. Do this:

  • If possible, allow ashes and coals to cool inside your grill for several days. These devices are designed to contain their heat safely.
  • When it is time to dispose of the materials, transfer them to a metal container and wet them down.
  • Keep the metal container outside your home and away from any combustibles until disposal day. Bag the wetted materials.
  • Do not place any other combustibles in the metal container and do not use a combustible container.
