Workers return to Dallas-area plastics plant following massive fire

Automatic TRANSCRIPT

Returning to the Dallas area plastics recycling and manufacturing plant that burned for hours yesterday. Also at the site. Now state environmental quality inspectors who are keeping tabs on the air and water around the building, the shelter in place order that was issued by the city of Grand Prairie has been lifted in the neighborhoods around the facility. But private physician Glenn Hardisty says staying indoors is still a good idea, because whatever's inhaled or come into contact with is likely to produce symptoms like irritated eyes and lungs. But the long term effects could be more serious. Plastic manufacturing does have potential carcinogens. 36 hours after the police started firefighters, they're still watching for flare up.
