Take Action To Minimize Mold and Dampness After Hurricane Irma

Tallahassee, Fla. — As Floridians clean and repair their storm damaged homes and buildings, the Florida Department of Health (DOH) urges the public to take action to avoid indoor air quality problems. Moisture that enters buildings from leaks or flooding accelerates mold growth. Mold can cause disease, trigger allergic reactions, and continue to damage materials long after the storm. Failure to control moisture and mold can present short and long-term health risks.


  • Protect yourself: Put on personal protective equipment (cleaning type gloves, N95 respirator/mask, and safety goggles) to protect your skin, mouth, nose, lungs and eyes.
  • Toss / Take it out: Anything that was wet with flood water and can’t be cleaned and dried completely within 24 to 48 hours should be taken outside. Take photos of discarded items for filing insurance claims.
  • Air out: Open all doors and windows when you are removing wet or moldy materials, or cleaning moldy surfaces.
  • Drying it out: When electricity is safe to use, you can close doors/windows and use fans and dehumidifiers to help remove moisture indoors. Remember that dehumidifiers can only dehumidify under closed indoor conditions. Dry your home and everything in it as quickly as possible – within 24 to 48 hours if you can.
  • Don’t mix cleaners: If you use cleaning products, do not mix cleaning products together because doing so can create toxic vapors.
  • Scrub surfaces: Clean with water and detergent. Remove all mold you can see. Dry right away.
  • Don’t cover it, remove it: Painting or caulking over mold will not prevent mold from growing. Fix the water problem completely, dry it out, and clean up all the mold before you paint or caulk.
  • Consider your medical status: Individuals with suppressed or impaired immune systems, mold allergies, asthma, or other chronic lung disease should not clean or remove moldy materials. See your doctor if you are unsure of your medical status or are not feeling well.
  • Prevent carbon monoxide poisoning: Never use gasoline or propane powered tools or generators indoors as these devices produce very hazardous carbon monoxide which can kill you within minutes. If you are using a generator, please place it at least 20 feet from all buildings. Install a battery operated carbon monoxide alarm in your home.
