WORKSAFE Victoria will visit Shell on Monday to probe how two contractors were exposed to potentially lethal gas in a leak at the Corio oil refinery yesterday.
Eight CFA crews from across Geelong were called to the Shell plant after the company sounded a major alert about 8.35am after hydrogen sulfide, a flammable and poisonous gas, was found to have leaked from one of the refinery pumps.
Yesterday's alert was deemed to be of the highest level of three available to Shell, according to CFA sources.
