Dozens of emergency vehicles amassed at the scene in the hours after the blast, as fires continued to smolder in the ruins of the plant and in several surrounding buildings. Aerial footage showed injured people being treated on the flood-lit football field that had been turned into a staging area.
Vanek said first-responders treated victims at about half a dozen sites, and he saw several injured residents from the nursing home being treated at the community center. Swanton said the injured rescued so far had been taken to hospitals in Waco and a triage center at high school in nearby Abbott.
About 100 of the injured were treated at Hillcrest Baptist Medical Center in Waco, where five people were in intensive care. Another 65 were taken to Providence Health Center in Waco. Officials said the injuries included broken bones, bruises, lacerations, respiratory distress, and some head injuries and minor burns.
Erick Perez, 21, of West, was playing basketball at a nearby school when the fire started. He and his friends thought nothing of it at first, but about a half-hour later, the smoke changed color. The blast threw him, his nephew and others to the ground and showered the area with hot embers, shrapnel and debris.
"The explosion was like nothing I've ever seen before," Perez said. "This town is hurt really bad."
Information was hard to come by in the hours after the blast, and entry into the town was slow-going as the roads were jammed with emergency vehicles rushing in to help.
The U.S. Chemical Safety Board said it was deploying a large investigation team to West. American Red Cross crews from across Texas also headed to the scene to help evacuated residents.
There were no immediate details available from police on the number of people who work at the plant, which was cited by the Texas Commission on Environmental Quality in 2006 for failing to obtain or to qualify for a permit. The agency acted after receiving a complaint in June of that year of a strong ammonia smell.
In 2001, an explosion at a chemical and fertilizer plant killed 31 people and injured more than 2,000 in Toulouse, France. The blast occurred in a hangar containing 300 tons of ammonium nitrate, which can be used for both fertilizer and explosives. The explosion came 10 days after the Sept. 11, 2001, terrorist attacks in the U.S., and raised fears at the time it was linked. A 2006 report blamed the blast on negligence.
