What Can we Do to curb indoor air pollution?

• Test for radon and formaldehyde inside your home and take corrective measures as needed.
• Do not buy furniture and other products containing formaldehyde
• Remove your shoes before entering your house to reduce inputs of dust, lead, and pesticides.
• Test your house or workplace for asbestos fiber levels and for any crumbling asbestos materials if it was built before 1980.
• Don't live in a pre-1980 house without having its indoor air tested for asbestos and lead.
• Do not store gasoline, solvents, or other volatile hazardous chemicals inside a home or attached garage.
• If you smoke, do it outside or in a closed room vented to the outside.
• Make sure that wood-burning stoves, fireplaces, and kerosene- and gas-burning heaters are properly installed, vented, and maintained.
• Install carbon monoxide detectors in all sleeping areas.
