The accident occurred in the Reactor 6 used to carry out the hydrogenation of a pharmaceutical intermediate.The operation of the plant was organized in two shifts. Since the hydrogenation at Reactor 6 would have taken at least 30 hours, it was not possible to complete the reaction during a single shift. The reaction was commenced at 8:00 a.m.

Hydrogen escaped when a venting valve was opened for the inspection of a cap. The escaped hydrogen caught fire, resulting in the death of 4 people, injuries to others 3 and damages to the plant.
