When the forensic engineers at WHA international first heard about a liquid oxygen (LOX) valve fire at an air separation unit (ASU), they had very little information to guide the investigation.

Nobody knew how the fire began or even when it occurred. Because the internal fire quickly self-extinguished, the system could have remained in operation for months or years before the damage was discovered.

Had the piping been breached, thousands of gallons of LOX would have drained out and flash vaporized into an area where personnel could have been present.
