The entire 15 Freeway was shut down east of Barstow Friday after a big rig hauling lithium-ion batteries crashed and caught fire, blocking Southern California's link to Las Vegas for more than nine hours, officials said.
The crash occurred just before 6 a.m. in the freeway's northbound lanes between Barstow and Baker, according to the California Highway Patrol.
Firefighters encountered burning lithium-ion batteries, prompting them to call for a hazardous material response, logs show.
The burning batteries posed multiple threats, San Bernardino County Fire Protection District officials said.
"This product, when involved with fire, can escalate to a thermal runaway, which requires massive amounts of water to extinguish," the agency said in a written statement. "To ensure public safety, a hard closure of both northbound and southbound lanes of the 15 freeway has been enforced. Public safety is of the utmost importance, and keeping the area clear allows emergency responders to manage the situation effectively and prevent potential harm."
In addition to the possibility of thermal runaway, in which the batteries undergo a chain reaction and potentially explode due to puncturing or crushing, lithium-ion batteries also produce toxic fumes, officials said.
Numerous triangular yellow placards displaying lightning bolt symbols to warn of electrical danger could be seen adorning the burning trailer.
Northbound traffic was stopped at Afton Road, while southbound traffic was halted at Basin Road.
No information was available regarding the condition of the driver.
Southbound lanes of the freeway were reopened about 3 p.m., while a "hard closure" remained in effect for northbound lanes, according to CHP and fire officials. Officials began intermittently allowing northbound traffic to use southbound lanes to pass. Southbound traffic was being intermittently stopped, however, to allow officials to bring in heavy equipment.
There was no estimate regarding when northbound lanes would reopen.
The batteries continued burning beyond 5 p.m.
Motorists reported spending hours sitting in place while temperatures soared to around 110 degrees. One southbound driver said he used up nearly an entire tank of gas idling on the freeway before turning around to head back north.
Several ambulances were summoned to the area to assist people suffering from heat-related illness.
"We are actively addressing the needs of motorists stuck without water and experiencing other issues. We strongly recommend that all individuals attempting to travel northbound divert and seek alternate routes as the closure is expected to be extended due to the hazmat and suppression operations related to the truck fire," according to an statement issued by fire officials Friday afternoon.
"Numerous calls for service have been received by our dispatch center from both Interstate 40 and the 15 Freeway. These include individuals exhibiting medical conditions and heat-related emergencies," the statement continued. "In response, County Fire has brought additional ambulances and paramedic fire apparatus to the area to address these calls."
"Expect major delays," the CHP said via social media .
