The U.S. EPA recommends that sensitive groups such as children, older adults, those with respiratory diseases, and people who are active outdoors limit prolonged outdoor exertion especially between the hours of 12:00 and 7:00 p.m. when the highest Ozone concentrations are most likely to occur.

Within a few hours or days, exposure to higher levels of Ozone can cause lung and throat irritation, shortness of breath, and aggravate respiratory diseases such as asthma, emphysema and bronchitis. For more information about Ozone and your health please go to: http://www.epa.gov/airnow/ozone-c.pdf
To do your share to protect air quality and reduce pollution levels:
· Conserve energy – turn off lights, reduce air conditioner use, etc.
· Use Public transit, or limit driving and avoid unnecessary idling and drive-through windows, especially if there are long lines.
· Postpone refueling your vehicle until after 6:00 p.m.; don’t ‘top-off’ the tank when filling up.

· Limit the use of cleaning fluids, paint thinners or other materials containing volatile organic compounds (VOC).
· Postpone painting projects or use low-VOC coatings.
