Text For Citation: 01 Item/Group: 002 Hazard: CHEMICAL

Section 5(a)(1) of the Occupational Safety and Health Act of 1970: The employer did not furnish employment and a place of employment which were free from recognized hazards that were causing or likely to cause death or serious physical harm to employees in that employees were exposed to: a) Hazard of breach of containment of liquid chlorine from the carrier coolers (pressure vessels), containing chlorine, hydrogen and air in the Liquifaction Process, which could result in chemical and thermal burns or being asphyxiated by chlorine. Three carrier coolers in the Liquefaction Building were not inspected and tested to determine the ingegrity of the vessels. One feasible and acceptable abatement method, among others, to correct this hazard is to inspect and test the carrier coolers that the maximum period between internal inspections or a complete on-stream evaluation of pressure vessels shall not exceed one half of the estimated remaining life of the vessels or ten years, whichever is less, except where the remaining operating life is less than four years, the inspection interval may be the full remaining safe operating life up to a maximum of two years, as stipulated in American National Standard Institute API-510, Pressure Vessel Code, Maintenance Inspection, Rating, Repair and Alteration, Section 4.3, Inspection Intervals. Violation observed on or about 10/21/87.
