Todd Spitler, an ExxonMobile spokesman, said the incident happened Wednesday morning.
“Our main concern is for the safety of our employees and our neighbors,” Spitler said, according to the LA Times. “We are accounting for all personnel and still evaluating the cause of the incident, or the occurrence or amount of any damages.”
