CORINNE — A 64-year-old Cache Valley man died after an explosion early Monday morning, March 26 at the Autoliv Facilities in Promontory.

Ronald Larson died shortly after arriving at the Brigham City Hospital with severe burns, according to a news release from Box Elder County Sheriff's Office Chief Deputy Dale Ward.

Officials were first called about a building fire at the Autoliv location at 2:12 a.m. When rescue crews arrived, employees were trying to rescue Larson, who was trapped in the building.

Larson was reportedly alone in the mixing portion of the building at the time of the explosion, for which a cause has not yet been determined, Ward said.

Autoliv spokesman Tom Hajkus told the Associated Press that the explosion occurred in a laboratory where it makes propellants for air bag inflators.

Hajkus said two other workers nearby were injured.

Box Elder detectives continue to investigate the incident and will be working with Occupational Safety and Health Administration, which will be the lead investigative agency since the location is an industrial accident, Ward said.

Autoliv is world's largest automotive safety supplier. The company is based in Sweden and has facilities in Promontory, Ogden, Tremonton and Brigham City. The Promontory facility is the same site of a 2015 explosion that injured an employee and a 2013 flash fire that left another man with burn to his arms and face.
