Many explosions at chemical plants were in the last time. One of them, two months ago, killed 14 people and injured about 200 in a fertilizer plant in Texas. Two weeks ago, one person was killed and 73 injured in Geismar, Louisiana.
THE U.S. Occupational Safety and Health Administration has a related statistic on the website, showing that in the last 35 years the explosions in grain handling facilities have killed 180 persons across the nation.
The real cause of this explosion is unknown. However, a safety expert from the Purdue University said that grain dust can be an explosive substance because it is very volatile.
The U.S. Bureau of Alcohol, Tobacco, Firms and Explosives investigates the scene.
A fact was clearly determined: no hazardous chemicals were involved or released as a result of explosion ever fertilizers are on storage elsewhere on the site.
Investigators have been looking at gas meters and pipelines. but. again, no results were communicated
