Fire Response and Recovery

Wildfires can create widespread threats to public health and the environment. Air quality can be affected by smoke, ash, toxins, and dust. Soil and water quality can be affected by uncontrolled hazardous materials and debris.

It is critical that response and recovery efforts quickly address any potential hazards. This will reduce impacts to surrounding communities.

Air Quality Issues

Wildfire smoke is a complex mixture of chemicals, gases, and fine particles. The biggest health threat from smoke comes from breathing fine particles.

Local officials may issue health warnings with specific instructions. Take steps to protect yourself and your family, such as avoiding smoky conditions and reducing outdoor work or exercise. Seek medical assistance if you have difficulty breathing or experience chest discomfort, wheezing, or shortness of breath. Even healthy people may experience some of these symptoms in smoky conditions.

Fire Debris: Hazards and Cleanup

Debris from burned buildings and homes contains toxic substances because of the many synthetic and other hazardous materials present. Older buildings may contain asbestos and lead. Homeowners may have gasoline, cleaning products, pesticides, and other chemicals stored in garages and sheds that may have burned in the fire. It is important not to expose yourself or your family to any of these materials.

Ash and Debris Information

NESHAPS Information

It is important to help minimize the release of asbestos into the environment following a fire. A number of local, state, and federal regulations, including National Emission Standards for Hazardous Air Pollutants (NESHAP), provide safe handling and proper disposal instructions for fire ash and debris containing asbestos. For specific NESHAPs requirements or other local air quality regulations, please contact your air district or the Air Resources Board (ARB).

Water Protection

Local officials may issue a Boil Water Order when drinking water is contaminated or if a fire has damaged waste water and sewage treatment systems. If a “boil water” order is issued, residents should not use their tap water for drinking, washing dishes, washing hands or bathing, for cooking, or brushing teeth without first boiling the water. More information is available at the California Department of Public Health (CDPH) Drinking Water Program. Fire assistance and cleanup information from the State Water Resources Control Board and the Regional Boards.
