Molds and mildew grow in damp, dark places. Molds and mildew can cause lung problems
especially in people who have allergies or asthma. You can prevent the growth of
molds and mildew in your home by controlling humidity.
Tips on Mold and Mildew:
- Control moisture. Use a dehumidifier during the summer. Use an
exhaust fan in the kitchen and bathroom. Vent the clothes dryer to the outdoors and make
sure the vent pipe is not clogged.
- Fix plumbing leaks before mold grows.
Dont store firewood inside. Bark contains millions of mold spores.

Make sure your home has lots of fresh air.
Use safe paints, cleaners and other products. Look for those with the fewest warnings.

Radon is a colorless, odorless, soil gas that can seep into your home through cracks in
concrete. Radon related lung-cancer causes thousands of deaths in the U.S. each year. Only
smoking causes more. All homes should be tested.
Tips on Radon:
Test your home. Many hardware stores sell low-cost test kits. Your local health
department may also have test kits. Make sure the kit has the words, "Meets EPA
Requirements" on the package. Test the air of the lowest floor of your home that is
lived in. If the radon level is less than 4 picocuries per liter, no action is needed.
If the level is above 4, repeat the test (or do a year-long test) to find the average
level in your home.
Correct the problem if the second reading is also above 4. Call the Radon Information
Center at 1-888-LOW RADON or contact your local public health department for more
information on Radon.

- If you think you may have asbestos in your home, contact a certified
asbestos inspector to find out what actions are needed.
- Dont try to remove asbestos by yourself. Only trained
professionals should do this work.
