BOX ELDER COUNTY, Utah — A commercial semitrailer hauling hazardous materials caught fire early Friday, closing westbound Interstate 84 for several hours near Pocatello Valley.
Tremonton City Fire Department crews were dispatched just before 3 a.m. to the reported vehicle fire and arrived to find both trailers of a double tractor-trailer fully engulfed in flames, according to a department statement.
Because the trailers carried oxidizing hazardous materials and the initial water supply at the scene was limited, firefighters let the blaze burn in a controlled manner until extra water and personnel arrived to safely attack the fire.
An engine from the Garland Fire Department and a water tender from the Snowville Town Volunteer Fire Department assisted with the response. Crews eventually brought the fire under control, and no injuries were reported.
Westbound lanes of I-84 remained shut down for several hours while emergency crews mitigated the scene. The Box Elder County Sheriff’s Office, Utah Highway Patrol, Box Elder Communications and Weber Area Dispatch 911 and Emergency Services District also assisted with the incident.
The cause of the fire is under investigation.
