Abstract
An anhydrous hydrogen fluoride cylinder released its contents in an explosive manner. The valve cap, valve, and valve boss assembly separated from the cylinder in the heat-affected zone of the boss-to-cylinder weld. Internal hydrogen pressure and a preexisting crack in the cylinder were evident factors in the failure. Eight adjacent cylinders stored under similar conditions were considered potential hazards, and precaustions were taken to minimize the risk from these cylinders.
