Gas & Your Health

Most people know that gas leaks can cause deadly explosions, but gas appliances are also a threat to your health, even without leaks. Like any fossil fuel, methane gas emits noxious fumes when burned. The resulting mix of nitrogen dioxide (NO₂) and other pollutants have serious health ramifications.

Nitrogen dioxide exposure results in increased respiratory symptoms, asthma attacks and hospital admissions. Long-term NO₂ exposure is likely to cause asthma, especially in children, and can increase the risk of diabetes, cancer, and premature death. 

Many homes with gas-burning appliances frequently exceed Environmental Protection Agency outdoor air quality standards, but because indoor air is unregulated by the EPA, the toxic fumes are perfectly legal.
