Two fertilizer companies facing litigation over the deadly explosion that rocked West, Texas have cast blame on the city and fire department for the disaster, the Waco Tribune-Herald reported Saturday. 

Fifteen people died and at least two hundred were injured in April 2013 when a fire that led to an explosion occurred at the West Fertilizer Co.. The facility was storing large amounts of ammonium nitrate. News agencies described the power of the blast in which some of the ammonium nitrate exploded as being as powerful as 15,000 to 20,000 pounds of dynamite.

The two companies, fertilizer manufacturer El Dorado Chemical Co. and fertilizer manufacturer and distributor CF Industries, are among the industrial defendants facing suit. According to previous reporting by the Tribune-Herald,

“The State Fire Marshal’s Office found that the city of West and the West Volunteer Fire Department did not properly plan for, train, or equip the firefighters of the WVFD to handle a fire at a high-risk commercial business,” the Texas paper cites the motion from CF Industries as saying.
