The first hour
- Stay inside. Close windows, doors and fireplace dampers. Turn off fans and HVAC.
- If you must go out, wear an N95 mask and goggles. Swap contacts for glasses.
- Avoid driving. Ash makes roads slick and clogs engines.
- Follow evacuation orders if given.
The first day
- Clear ash from roofs carefully once it's safe. USGS: about 4 inches of ash can stress roofs, and wet ash weighs much more.
- Dampen ash lightly before sweeping to keep dust down. Don't wash it into drains.
- Keep pets inside and rinse their paws.
The first week and beyond
- Check water sources if you collect rainwater.
- Change air and car filters often.
