How to reduce the vulnerability of attic and crawl spaces

  • Avoid storing combustible items (e.g., cardboard boxes, newspapers and magazines) near attic or crawl space vents. 
  • Inspect vents to make sure they are in good condition (i.e., screen is in good condition with no tears that would result in larger openings). 
  • If ¼-inch mesh screening is present, replace or add, at a minimum, a ⅛-inch noncombustible corrosion resistant metal mesh screen.
  • Consider replacing vents with a flame- and ember-resistant option.
