Pa. declares Code Red due to poor air quality from Canadian wildfires

The Delaware Valley has seen the worst of this iteration of Canadian wildfire haze, but air quality alerts remain in effect.

On Friday afternoon, Pennsylvania declared a Code Red Air Quality Action Day for the entire commonwealth. The state Department of Environmental Protection noted that, though conditions will continue to improve, Code Red conditions persist in most of the state.

Under a Code Red, air pollution concentrations are considered unhealthy for the general population and outdoor activity should be avoided.

Under Code Red conditions, experts recommend that everyone avoid the outdoors, keep windows shut, and run air conditioning on a re-circulation setting. Those who go outside are encouraged to wear a high-quality mask, such as an N-95 or KN-95, to reduce pollution exposure.

Philadelphia declared a Code Orange on Friday, though city officials noted air quality may vary by neighborhood. Residents are encouraged to visit AirNow.gov to check local conditions.

Under a Code Orange, air pollution concentrations may be unhealthy for vulnerable groups such as children, people with asthma, people with heart or lung disease, and older adults.

South Jersey and Delaware are similarly experiencing Code Orange conditions.
