DALLAS (Reuters) - A deadly 2013 fertilizer warehouse explosion in Texas that claimed at least 14 lives could have been prevented, U.S. safety investigators said on Tuesday.
Between 40 and 60 tons of ammonium nitrate exploded 22 minutes after a fire broke out at the West Fertilizer Co warehouse on April 17, 2013, leveling a neighborhood in the town of West, 70 miles southwest of Dallas.
The ammonium nitrate, which the company supplied to farmers to use as fertilizer in the region, was stored in wooden bins within a wooden building that did not have a sprinkler system, said Rafael Moure-Eraso, chairman of the U.S. Chemical Safety Board.
"(The fire and explosion) resulted from the failure of a company to take the necessary steps to avert a preventable fire and explosion and from the inability of federal, state and local regulatory agencies to identify a serious hazard and correct it," Moure-Eraso said.
The fertilizer should have been stored in fireproof structures to protect it from possible ignition sources within a concrete building with a sprinkler system to suppress a blaze, he said.
Many U.S. fertilizer warehouses store ammonium nitrate in wooden bins, the board said.
The CSB said the state of Texas and federal regulators had much to do to strengthen rules to prevent explosions like the one in West, which injured 236 people.
"Our findings so far show that there is a patchwork of federal and state regulations with huge gaps that allowed this accident to happen," said Johnnie Banks, the board's lead investigator.
Volunteer firefighters battling the blaze did not know the risks they faced from fertilizer stored at the warehouse, because of lax regulation of volunteer training and inadequate preparations for fires at chemical facilities, he said.
Firefighting associations and the chemical industry offer differing guidance on how to fight a fire involving ammonium nitrate. Some say a large blaze should be allowed to burn while others say the flames should be doused with water.
