Incident Description
On October 11, 2008, a transfer operation overflowed an oleum process tank, filling a vent system and releasing the oleum into a storage building at Indspec Chemical Corporation in Petrolia, Pennsylvania . The release of oleum created a cloud of sulfuric acid mist that filled the building and flowed out into the facility and surrounding community. Plant personnel evacuated the facility, while emergency responders evacuated about 2,500 residents from the towns of Petrolia, Bruin, and Fairview.
