ACCIDENT DESCRIPTION:

To gauge the level of crude oil in a battery tank 12 feet high by 20 feet in
diameter, the worker climbed the stairway to a platform near the top of the
tank. He was immediately overcome by H2S gas escaping from a relief valve.
The tank incorporates a gas recovery system using a venturi (a short, narrow
piece of tubing inserted in a pump or pipeline to permit measurement of the
rate of flow of liquid or air) to draw gas from the tank. It had been frozen
off, allowing gas to accumulate in the tank and vent to the atmosphere. The
worker was not wearing his respiratory protection apparatus although he had it
in his truck; it was checked and found serviceable.
