HACEINDA HEIGHTS — A big rig believed to be hauling compressed hydrogen cylinders caught fire on the 60 Freeway in Hacienda Heights Thursday afternoon, prompting authorities to shut down both directions of the freeway.
The fire was reported just before 2:50 p.m. on the eastbound side of the freeway near Hacienda Boulevard, according to California Highway Patrol logs. The truck was hauling long cylinders believed to contain compressed hydrogen
Firefighters pumped water onto the fire from a distance, and CHP officers kept traffic well away from the burning big rig, diverting motorists off at nearby exits.
Eastbound traffic was initially being diverted at the Seventh Avenue offramp, however officials ultimately closed eastbound traffic all the way back to the 605 Freeway, CHP Officer Patrick Kimball said. Westbound traffic was being diverted of the 60 Freeway at Azusa Avenue, creating a mile-long buffer between the fire and freeway traffic.
The fire was largely extinguished by 4 p.m., however authorities still considered the trailer to pose a risk of potential explosion, Los Angeles County sheriff’s officials said.
“Where we stand right now, we’re still cooling the tanks, letting the tanks vent into the atmosphere,” Los Angeles County Fire Department Inspector Scott Miller said shortly before 4:30 p.m.
Once the tanks were emptied, he said, officials hoped to start working to move the scorched remains of the truck and reopen the freeway.
No injuries were reported in connection with the fire, Miller said.
Deputies were preparing to evacuate homes if necessary along residential streets, particularly those just south of the truck fire.
It was unclear how long the freeway would remain closed as a result of the fire.
