Caution! Ash from burned structures may have blown and entered your home garden or landscaped areas. Ash from fires can contain toxic chemicals that can be harmful to your health.
Follow these recommendations to keep you and your family safe from ash in your yard or garden (or other outside areas):

- Only touch ash to remove it while wearing an N95 mask, gloves and protective clothing
- Prevent ash from entering your home

Fire Ash Can Be Unhealthy
The ash from structure fires is not the same as ash from burned vegetation or wood. Contaminants in ash from structure fires can contain hazardous chemicals. Ingesting or inhaling these chemicals is not good for your health.
Contaminants can include:
- Asbestos
- Chemicals from paints, plastics, insulation and other building materials
- Lead, arsenic, mercury and other toxic heavy metals
- Benzene, formaldehyde, dioxins and other volatile organic compounds (VOC's)ā
Limit Contact with Ash
- Avoid touching ash in the yard, garden, walkways and driveways, as well as outdoor surfaces such as garbage cans, mailboxes and patio furniture
- Protect your lungs, skin and eyes by wearing an N95 mask, gloves, goggles and protective clothing when removing ash
- Pregnant women, older adults, children and people with heart or lung disease, including asthma, should take extra precautions to avoid contact with ash
- Do not allow children to play with ash and wash off toys before use
Leave Ash Outdoors
- Change your shoes and clothing to avoid tracking ash into your car, home, or other places
- Wash clothing soiled with ash in a separate load
- Keep pets away from ash and prevent them from tracking it into the home
Safely Remove Ash from the Garden
- Wait until conditions outside clear before removing fire ash from your garden
- Try not to get ash into the air. Do not use leaf blowers
- Wet ash down and sweep into a garbage bag before removing
- Securely store ash in enclosed plastic bags or containers. Dispose in regular trash
- If ash does get on your skin, wash it off as soon as possible
- Avoid washing ash into storm drains
- Never use fire ash as fertilizer or soil conditioner in your yard or garden
- When there has been a lot of ash, use raised garden beds (also called garden boxes) with clean soil or remove topsoil
