Two contractors performing maintenance work at Tesoro’s (TSO -0.4%) Golden Eagle refinery in northern California suffered burns yesterday when they were splashed with sulfuric acid, an accident that occurred in the same processing unit where two employees were burned by acid last month.

The first incident prompted state and federal regulators to raise broader questions about how TSO runs the plant; TSO said an investigation by the U.S. Chemical Safety Board was biased and that the agency overstepped its bounds.

TSO claims yesterday's accident is unrelated to the Feb. 12 chemical release.
