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. A vessel of 130 US gallons (490 L) of the chemical was boiling and may have ignited when a plastic rack was lowered into it.[4]
In popular culture
The event served as the main inspiration for "Nicholson Electroplating", a fictional case featured in the 2011 video game L.A. Noire.[5]
