Buildings at the Ireco Inc. plant lie in ruins after Monday morning's blast. Officials of the plant continue to sift through the rubble trying to determine the cause of the explosion, which destroyed building 1-A and caused extensive damage to nearby storage facilities. Officials from OSHA and the Bureau of Alcohol, Tobacco and Firearms are expected to inspect the site sometime this week. Early reports indicate that a faulty valve at the Pelican Point, Utah County, explosives plant caused a mixer to overheat, which detonated more than 2,000 pounds of explosive nitrate salts. Investigators say a "blast wall" installed in the building a few years ago probably saved four workers north of the wall when the building exploded. Had the workers been south of the wall they likely would have been killed, investigators said.
