Authorities in Port Neches, Texas, have issued an order encouraging residents to evacuate due to concerns over air quality after the chemical plant explosions that occurred last week.
Elevated levels of the chemical butadiene were detected late Wednesday. Jefferson County emergency management officials said the levels did not pose a serious health risk but could cause dizziness, nausea, headaches or irritation to the eyes and throat.
Butadiene is a chemical used to make synthetic rubber and other products. The first explosion happened on November 27 at the TPC Group plant and shattered windows and ripped doors off the hinges of nearby homes. A second blast occurred about 13 hours later. The fire wasn’t contained until November 29.
