Reduce the entry of pollutants from the garage to the living areas of the home.
- Seal cracks or openings in any walls or ceiling that are shared with the living areas of the house. This includes where walls meet the ceiling or floors, electrical and plumbing outlets, or central vacuum systems.
- Do not leave the door from the garage to the home open.
- To prevent pollutants from building up, such as when working on an engine or using toxic materials, have the garage door open and run the garage exhaust fan if you have one. Even if the garage door is open, use the exhaust fan.
