TAS Environmental workers attempt to suck up water and chemical run off in drainage ditches near the Magnablend Inc. chemical facility in Waxahachie following an explosion and massive fire earlier in the week. The fire started as workers mixed chemicals at the plant south of Dallas shot massive plumes of black smoke and bright orange flames into the sky October 3, 2011, forcing schoolchildren and residents to evacuate or take cover indoors to avoid possible exposure to dangerous gases.
