Black smoke billows from Texas chemical plant fire

A fire at a chemical plant south of Dallas shot massive plumes of black smoke and bright orange flames into the sky Monday, forcing schoolchildren and residents to evacuate or take cover indoors to avoid possible exposure to dangerous gases. Flames engulfed what appeared to be several areas of a large complex at a Magnablend, Inc., facility in Waxahachie, about 30 miles south of Dallas. Images from local television stations showed the fast-moving blaze consuming a fire truck at the scene and flames nearing railroad tracks alongside the property.
