Explosion in Dayton releases toxic gas

There were no injuries, but a cloud of toxic hydrogen triflouride gas was released in an explosion that seriously damaged an industrial plant Sunday morning.

Advanced Specialty Gasses is located about one mile east of Smith’s Food and Drug on U.S. 50 East at 38 Enterprise Way. The quad-county hazmat team, as well as fire departments from Lyon County, Reno, Truckee Meadows and the Nevada Division of Forestry responded to the explosion, which occurred at 11:52 a.m. An ensuing brush fire was quickly suppressed.

The company uses hydroflouric acid and anhydrous ammonia to produce hydrogen triflouride, a substance used in the computer industry. All three substances are hazardous. Three employees working in the plant at the time of the explosion responded to contain the damage, but a cloud of yellow hydrogen triflouride was released. It dispersed quickly after the explosion.



A spokesperson for the company said all safety systems worked as expected.

It is not known how much of the gas was released, but officials from the Central Lyon County Fire Protection District determined that the nearest residential area, Mark Twain Estates, was in the safety zone.




The explosion blew off part of the roof of the plant and seriously damaged the interior of the building, blowing four-inch metal doors off their hinges.

The cause of the explosion is under investigation.
