Steam Explosion Jeopardizing Worker Safety at SCVMC Hospital Construction Site

This video is actual footage taken at the Turner Construction site at a Santa Clara Valley Medical Center on Sept. 3, 2014. The video shows workers activating the steam system for the North Utility Loop which provides steam and chilled water to the facilities at Valley Medical Center. During the course of the process for starting the steam system, the audio clearly demonstrates a loud popping sound, followed by verbal concerns expressed by crews on site. Then, after over a minute of the audible popping noises, as a crew member attempts to escape the underground vault, the pipe explodes discharging boiling hot steam.
