The Department of Environmental Protection forecasts a Code Orange Air Quality Action Day warning for particulate matter-- PM 2.5-- for Friday, November 6 in the Liberty-Clairton Area of Allegheny County.
A strong meteorological inversion expected in the morning, coupled with calm winds, will result in daily average fine particulate matter concentrations reaching the Code Orange range, with the highest concentrations expected Friday morning before the inversion breaks up late in the morning.
An air quality action day, which is determined based on the forecasted air quality index, means air pollutants are at unhealthy levels for vulnerable populations.
On these days, young children, the elderly, and those with respiratory problems, such as asthma, emphysema, and bronchitis, are especially vulnerable to the effects of air pollution and should limit outdoor activities.
Residents and businesses within the Air Quality Action Day area are strongly encouraged to voluntarily help reduce air pollution by:
-- Conserving electricity by setting air conditioning to a higher temperature;
-- Combining errands to reduce vehicle trips;
-- Limiting engine idling; and
-- Refueling cars and trucks after dusk.
This forecast was issued in cooperation with the Southwest Pennsylvania Air Quality Partnership.
