Two workers at the Tesoro refinery in Martinez were treated and released from a hospital after being burned in an acid spill on Wednesday, according to officials from Tesoro and the California Division of Occupational Safety and Health.
The workers were splashed with sulfuric acid around 2:40 a.m. at the refinery, located at 150 Solano Way, where they were treated before being airlifted to UC Davis Medical Center in Sacramento, Contra Costa County Fire Protection District Capt. Robert Marshall said.
Tesoro spokeswoman Megan Arredondo said the employees were treated for minor injuries and have since been released.
The workers were injured while working in one of the refinery’s gasoline production units, she said.
That unit has been shut down, and outside agencies including Contra Costa Health Services and the Bay Area Air Quality Management District have been notified of the incident, Arredondo said.
She said Tesoro is looking into what caused the accident.
Cal/OSHA spokesman Greg Siggins said the state agency is also investigating the accident and confirmed that the workers suffered injuries that are not considered life-threatening.
He said Cal/OSHA’s investigation could take up to six months.
