Massive industrial fire burning at EMR facility in Delaware County

A massive industrial fire is burning in Delaware County, Pennsylvania, on Wednesday, sending a huge plume of dark black smoke into the sky.

Chopper 3 is over the scene near Calcon Hook Road and Hook Road in Darby Township, where multiple fire crews are working to put out the blaze.

According to Delaware County officials, the fire is burning at a scrapyard near the EMR Recycling facility.

In a social media post, Darby Township urged residents to avoid the area and keep windows and doors shut.

The city of Philadelphia also issued an alert notifying residents that smoke is likely visible in Delaware County and beyond and could impact air quality. The health department is recommending people avoid going outside as much as possible and keep windows and doors closed.

EMR plant in Camden the site of multiple fires in recent years

Wednesday's fire in Delaware County comes just days after EMR's facility reopened in Camden, New Jersey.

The Camden plant was shut down for weeks after experiencing multiple fires, including one most recently on May 29. The facility opened after a judge ruled officials didn't follow proper state and local rules when city council voted earlier this month to keep it closed.

However, EMR was only permitted to resume operating with a number of additional safety protocols in place.

The company has blamed its spate of fires on improperly discarded lithium ion batteries.

A previous version of this story indicated the fire originated in Southwest Philadelphia.

This is a developing story and will be updated.
