OSHA has cited a Frozen Food Manufacturer for six serious process safety management (PSM) violations. At about 1:40 PM on July 20, 2013, approximately 13,800 pounds of anhydrous ammonia was released when a telescoping boom attachment being moved by a forklift under one of the HPR’s struck the pipe stem located at the bottom of the vessel, causing a rupture in that vessel, spilling the entire contents of the HPR and the ammonia refrigeration system.
