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.
This form of the acid is stable indefinitely and is commercially available. Such solutions are hygroscopic. Thus, if left open to the air, concentrated perchloric acid dilutes itself by absorbing water from the air. Dehydration of perchloric acid gives the anhydride dichlorine heptoxide: [10] 2 HClO 4 + P 4 O 10 → Cl 2 O 7 + H 2 P 4 O 11
A shipping container transported perchloric acid, a precursor to rocket fuel, but authorities don't expect any lingering environmental issues. Nebraska railyard explosion is not expected to have ...
BLEVE–fireball, 2008 Toronto propane explosion The following is a list of boiling liquid expanding vapor explosion (BLEVE) accidents. It shows whether the accident occurred during dangerous goods transportation or at a fixed facility, the accident origin (e.g., storage, process reactor, rail tank car, tank truck), the material involved, its amount, the number of fatalities, and whether a ...

Calcium perchlorate is a strong inorganic oxidizing agent, enhancing the combustion of other substances that can potentially lead to explosion. The perchlorate ion, ClO − 4, has a highly symmetrical tetrahedral structure that is strongly stabilized in solution by its low electron-donating proton-accepting power and its relatively low polarizability.
One synthesis uses fluorine and perchloric acid, [4] though the action of ClF 5 on water is another method. [citation needed] F 2 + HClO 4 → FClO 4 + HF. Another method of synthesis involves the thermal decomposition of tetrafluoroammonium perchlorate, NF 4 ClO 4, which yields very pure FClO 4 that may be manipulated and frozen without ...
