SANDY, Utah – Traffic was running slow on Interstate 15 in southern Salt Lake County after a semi trailer hauling PVC glue caught on fire.

Crews were called to the scene at I-15 and 9100 South in Sandy around 3:40 a.m. Sunday.

Officials with the Utah Highway Patrol said they received reports of the fire.

Trooper Tara Wahlberg said the driver pulled over after experiencing some mechanical issues and discovered that the axels were on fire.

The driver tried unsuccessfully to put the fire out herself.

Heavy flames were seen coming from the trailer. Wahlberg said it was fully engulfed when crews arrived on the scene.

Firefighters were able to extinguish the flames.

The driver was transported to the hospital to be treated for smoke inhalation and minor burns. She has since been released.

No other injuries were reported.

The truck was hauling PVC glue, which Wahlberg said was highly flammable. HAZMAT crews went to the scene to help with clean-up, though officials said there no contamination risk to the water or the air.

Southbound lanes were closed while crews fought back the blaze. Traffic was still moving through the area in the left lanes and HOV lane.

Crews were working to assess damages to the roadway. They didn’t expect the interstate to be fully opened until around noon.
