SCRR 71-112A: Failed to furnish a place of employment which is free of recognized hazards which may cause death or serious physical harm to his employees and comply with this regulation and other occupational safety and health rules and regulations promulgated under Chapter 15 of Title 41, Code of Laws, State of South Carolina, 1976, as amended, as follows: A. Employer knew or should have known that three maintenance mechanics, while removing a blind flange cover on the DR-501 reactor that utilized hydrogen in the Purified Terephthalic Acid unit of Plant Two, were exposed to the hazards of fire and explosion from a hazardous atmosphere. A feasible and useful method to correct the hazard among others, is to: 1) Install and maintain a liquid level detector that can be monitored during a line/flange break to ensure there is not loss of level and thus pulling outside air into the reactor. 2) Install a valve prior to the number one crystallizer to maintain a liquid full reactor. 3) visually verify the overflowing of water from all nozzles and vents to ensure a liquid full reactor.
