Keep Combustible Materials Away from Your Furnace

Although furnace rooms function as laundry and storage space, you should keep yours free of clutter that could be fire hazards.

This includes:

  • Clotheslines
  • Cleaning or laundry products
  • Gasoline, paint or paint thinner
  • Rags and papers
  • Wood scraps and sawdust
  • Used filters
