John E. Simon died after attempting to save Harold D. Snyder from suffocation, Monaca, Pennsylvania, July 24, 1985. Snyder, 33, entered a zinc dust condenser chamber at a metals processing facility and collapsed in its oxygen-deficient atmosphere. Simon, 36, oxide packer, who was working in another department of the plant, learned of the accident and went to the scene, as did others. He put on a self-contained breathing apparatus but found that he could not enter the chamber with it. He then removed the apparatus, entered the chamber, and, before he could put the apparatus back on, fell unconscious inside the chamber. Both Snyder and Simon were removed from the chamber by others, but neither could be revived. 60522-7002
