Summary
This bulletin analyses a fatal acetylene explosion at ASCO in Perth Amboy. Gas backflow through the recycled-water system accumulated in an unventilated shed; the heater was the most likely ignition source. It examines valve failure, operating sequence and building design, recommending positive isolation, reliable procedures, training and valve inspection.
