Update on Pasadena, Texas Incident

February 16, 2010 at 9:50 p.m. EST

At approximately 4:45 p.m. CT, Air Products' nitric acid plant in Pasadena, Texas shut down unexpectedly. This was followed by a pipe leak that resulted in the formation and release of a nitric oxide vapor cloud. The cloud passed to the southeast in the direction of Highway 225. There was no fire nor injuries at the plant or significant damage to the plant itself. Emergency responders were notified immediately according to protocol.

Emergency responders were notified immediately and initiated a shelter-in- place. The leak was contained and the plant was secured. The cloud had dissipated into the atmosphere by approximately 6:15 p.m., and the plant all clear signal was sounded. Air monitoring was performed in the surrounding area by the Harris County HAZMAT team. Nitric oxide levels were non-detectable, and the shelter-in-place was lifted by authorities.

We are investigating this incident to determine the root cause. We regret any inconvenience and delays this may have caused.
