The explosion was caused by the improper handling of perchloric acid, which the plant was using as an experimental method for polishing aluminum. On the day of the accident, the cooling unit required to store perchloric acid safely was not working.
Given its strong oxidizing properties, perchloric acid is subject to extensive regulations as it can react violently with metals and flammable substances such as wood, plastics, and oils. [16] Work conducted with perchloric acid must be conducted in fume hoods with a wash-down capability to prevent accumulation of oxidisers in the ductwork.
Fume hood units designed for procedures involving perchloric acid feature a water-wash system in the ductwork and are often built from marine grade stainless steel or rigid polyvinyl chloride, [43]: 36 Because dense perchloric acid fumes settle and form highly reactive perchlorate crystals, the internal baffles of the fume cupboard and ductwork ...

Ammonium perchlorate (AP) is produced by reaction between ammonia and perchloric acid.This process is the main outlet for the industrial production of perchloric acid.The salt also can be produced by salt metathesis reaction of ammonium salts with sodium perchlorate.
A criticality accident occurred on December 30, 1958, at Los Alamos National Laboratory (LANL) in Los Alamos, New Mexico, in the United States It is one of 60 known criticality events that have occurred globally outside the controlled conditions of a nuclear reactor or test; though it was the third such event that took place in 1958 after events on June 16 [1] at the Y-12 Plant in Oak Ridge ...
The 1947 Texas City disaster was an industrial accident that occurred on April 16, 1947, in the port of Texas City, Texas, United States, located in Galveston Bay.It was the deadliest industrial accident in U.S. history and one of history's largest non-nuclear explosions.
Lab demonstration with burning lycopodium powder. A dust explosion is the rapid combustion of fine particles suspended in the air within an enclosed location. Dust explosions can occur where any dispersed powdered combustible material is present in high-enough concentrations in the atmosphere or other oxidizing gaseous medium, such as pure oxygen.
