This is some AMAZING FOOTAGE of how QUICKLY an entry can go WRONG! Listen to the worker’s discussing their concerns about entering the pit before the accident occurrs (WARNING – HARSH LANGUAGE). The Supervisor just orderdd the entrant “to step out for just a minute” when the entrant climbed the ladder and had his head outside the space when the steam was released, lifting the worker out of the vault. The worker was shaken but walked away unhurt. Santa Clara County officials released the video they say shows a worker being blasted from a manhole by a steam explosion a year ago at the Valley.
