Hazardous Waste

Depending on your appliance you may have an ash box beneath your fire box. Some of these actually pull out, allowing you to easily dump it. Others have a door beneath the firebox for ash removal, and some furnaces keep the ash in the firebox itself. No matter the type of appliance you use, however, the ash can build up quickly and become a hazard.

Ashes can be dangerous because even when they look cold, and seem cold, they can actually be very hot. These ashes, when allowed to fill the firebox, can fall out onto carpet, or nearby combustibles in your home and catch fire. They can also be dangerous if handled incorrectly.

When to Remove Ashes

Although it seems a good idea to remove ashes often, some even removing them daily, it isn’t recommended. Chimney Safety Institute of America (CSIA) recommends leaving at least an inch of ash in the fire box at all times. This ash insulates the coals to keep them hot longer, while also keeping the bottom of the firebox cool, protecting your furnace and your flooring from excess heat.

However, it is a good idea to remove ashes when they begin to cover the coals following a regular burn cycle.

Removing the Ash

When you’re ready to remove the ash you should have the ash bucket on hand. Shovel the ashes into the bucket, taking care to not stir the ash more than needed. Shovel the ashes from the back of the firebox where there may be buildup, and remove it from the front where it may cover a vent. Once you have shoveled all you want into the bucket, set it aside to cool. It can cool outside or inside, but should be kept away from combustibles.

Disposing of Ash

In some areas and cities you may be able to bag cooled ashes, and simply place them with your regular trash pick-up. If this isn’t a possibility for you, you may want to utilize those ashes in creative ways. Some ways people use ashes include:

  1. In the garden. You can mix ashes with soil to change the acidity or sprinkle ashes directly onto plants to repel bugs.
  2. In the kitchen. You can mix ashes with water to shine silver, and clean glass and stainless steel. Save on oven cleaner by keeping this mixture on hand.
  3. On the driveway. Spread ash onto the driveway, porch, or sidewalk to add traction and to melt ice during winter weather.
  4. On your pet. To neutralize odors on household pets, rub a small amount of ash into the fur. You can also use ashes beneath cat litter to neutralize odors in the litter box.

However you use your ashes, it’s important to take safety precautions to prevent fire, burns, and injury.
