Ozone Action Days are hot, sunny, and dry days when ground-level ozone levels are expected to be unhealthy for people and plants. Here are some things you can do to help reduce your exposure to ozone and air pollution on these days: Stay indoors If ozone levels are high or you're sensitive to air pollution, try to stay inside in a building with good air filtration, like a library. Limit outdoor activities Try to reduce the amount of time you spend outside, and choose less strenuous activities when you do go out. You can also try to schedule outdoor activities for early in the morning, when ozone levels are lower. Protect yourself Wear a mask or respirator that filters out fine particles, and seek shade or areas with less sun exposure. Reduce your impact Limit car trips, and when you do drive, try to refuel after dusk, avoid idling, and follow proper refueling instructions. You can also try to combine errands and reschedule discretionary trips. Use less polluting products Use household, garden, and workshop chemicals sparingly, or try to delay using them when air quality is poor. You can also try to use paint and cleaning products with fewer or no volatile organic compounds (VOCs). Maintain your equipment Keep your car, boat, and other engines tuned up, and make sure your tires have the proper pressure. For your yard equipment, change the oil and replace air filters regularly, and consider using non-motorized tools instead.
