RI 4994 Investigations On The Explosibility Of Ammonium Nitrate ? Introduction

Disasters such as occurred at Oppau, Germany, in 1921, at Tessenderloo, Belgium, in 1942, and in this country at Texas City, Tex., in 1947 clearly indicate the explosive hazard associated with the manufacture, storage, and transport at ion of ammonium nit rate The importance and extent of the hazard may be Judged from the large amount of ammonium nitrate produced and transported annually in this country. Between July 1, 1947, and June 30, 1948, it was estimated that the United States produced 461,528 tons of ammonium nitrate commercially for agricultural purposes alone .5/ In addition, U. S. Army Ordnance plants have manufactured and shipped 779,730 tons of ammonium nitrate fertilizer to Germany, Japan, and Korea.6/
