PACHECO (KCBS)— Two people working at the Tesoro Golden Eagle refinery near Martinez were injured on Monday morning after they were exposed to sulfuric acid, according to county officials.
The incident happened just before 11 a.m. when two contractors were splashed with the acid.
The workers were decontaminated on site according to the Contra Costa Fire Department. Fire Inspector Steve Aubert said one worker was “saturated” and taken to John Muir Medical Center with injuries, while the other worker, who only received “minor contact” was able to walk away on his own accord.
Two workers were injured at the same refinery on February 12 after they were burned by sulfuric acid.
Contra Costa County Hazardous Materials Specialist Maria Duazo said this incident wasn’t as serious as last month’s and that both workers were wearing full protective gear when it happened.
“They were transported to UC Davis the first time, which is a more upgraded level of treatment,” she said.
Tesoro initially blocked federal officials from investigating that incident.
The county’s hazmat department has launched an investigation.
“One of the things we want to find out is what was the cause of the incident, how can we prevent the incident, document review on if it was process related or not,” Duazo said.
Tesoro representatives sent KCBS an email that stated, “The cause of the incident is under investigation and is believed to be unrelated to the chemical release that occurred on February 12th.”
