Text For Citation: 01 Item/Group: 010 Hazard: CHEMNEP

29 CFR 1910.119(e)(3)(i): The process hazard analysis did not address the hazards of the process: The employer does not address items in the process hazards analysis such as the identification of previous incidents; engineering and administrative controls applicability to the hazard; consequence of failure of engineering and administrative controls; facility siting; human factors; and qualitative evaluation of a range of possible safety and health effects of failure of controls on employees in the workplace including but not limited to: 1.Evaluate possibility of highly hazardous chemicals accumulating in sumps, pits or open ditches that could result in fires, reactions, toxic gas generation etc. 2.Evaluate the possibility that operational controls and interlocks may be by-passed or over- ridden. 3.Evaluate the possibility of ingress of flammable/combustible materials into enclosures such as control rooms, or analyzer shacks etc, that contain ordinary electrical equipment. 4.Evaluate the effective control of barriers to protect equipment such as but not limited to vessels, tanks, piping, and valve stations containing highly hazardous chemicals from vehicular impact. 5.Evaluation of the possibility of inadvertent mixing of highly hazardous materials. 6.Evaluation of the consequence of power failure. 7.Evaluation of failure of safety devices such as relief devices and the consequence on employees in the workplace. 8.Evaluation of expansion pots and/or relief devices where the potential exists to trap liquid chlorine. 9.Evaluation of the chlorine system to accumulate nitrogen trichloride in equipment. 10.Evaluation of unit piping to ensure that it is designed to ensure that process fluids cannot backflow into the chlorine system. 11.Evaluation of operators wearing respirator while connecting and disconnecting chlorine containers or piping. Pursuant to 29 C.F.R. 1903.19, within ten (10) calendar days of the date of this citation, the employer must submit documentation showing that it is in compliance with the standard regarding process hazards analysis. A method of abatement is complete a process hazards analysis that includes such items as the identification of previous incidents; engineering and administrative controls applicability to the hazard; consequence of failure of engineering and administrative controls; facility siting; human factors; and qualitative evaluation of a range of possible safety and health effects of failure of controls on employees in the workplace as per 29 CFR 1910.119(e)(3)(i) through (vii).h
