Work Permit Failure? Two Men Killed by Nitrogen

Two men died in a tank containing nitrogen gas at Valero Refinery, Delaware City on 5 Nov 2005.

Reports indicated that a work permit had been issued for setting up equipment on the tank, but the permit did not contain information regarding hazard of nitrogen inside the vessel.

It was reported that the first victim may have collapsed and fallen into the tank while trying to retrieve a dropped item, using a hook made out of wire.

Reports and a video re-enactment of this incident are available from the US Chemical Safety and Hazard Investigation Board
