malfunctioning. It is presumed the valve was frozen in the partially
open
position. Of their own volition, workers chose to use a propane
open flamed
torch to free the valve. Flame propagation through the partially
open valve
ignited an explosive mixture in the vacuum tank. The ignition
blew off the

a third. All three were fatally injured.
