HOUSTON – The fertilizer plant explosion and fire in West, Texas, happened on April 17, 2013, killing 15 people and causing hundreds of injuries among the rural area’s 2,800 people.
Here’s a look at NBC footage of the explosion from eyewitnesses.
So what happened? Here’s a look back at the explosion, as it happened with animations, from the U.S. Chemical Safety and Hazard Investigation Board.
The explosion flattened the farming community, just north of Waco, turning some 500 homes into rubble as residents tried desperately to flee the horrific scene. More than 200 people were injured, NBC News reported.
The force felt was equivalent to that of a magnitude-2.1 earthquake, and a 93-foot-wide crater scarred the site of the fertilizer plant, where dangerous chemicals, including ammonium nitrate, were stored.
Ten first responders and two volunteers were among those killed while fighting the initial blaze before the blast occurred just before 8 p.m. local time.
A state bill HB 942 passed in 2015 in response to the West disaster. The law adjusted guidelines for ammonium nitrate storage facilities. The law says, among other things, that the operator of a facility storing ammonium nitrate used in fertilizer must give notice to the state and local emergency entities and the facility must be examined by a fire marshal and the substance be kept separate by at least 30 feet from other materials.
Other issues, such as unidentified chemical facilities across the country, remain an issue that has been discussed. Somewhat connected to this issue -- efforts to improve the Chemical Facility Antiterrorism Standards program -- the nation’s first regulatory program focused specifically on security at high-risk chemical facilities -- continue through recent years with one program focusing particularly on ammonium nitrate, the chemical at the center of the West disaster.
