OSHA cited Pilgrim’s Pride Corp. for two repeat and two serious violations under its process safety management (PSM) standards after inspectors found that the nation's largest chicken producer failed to use proper safety procedures that allowed a release of 79 pounds of anhydrous ammonia and endangered workers at its Waco, Texas, facility on Sept. 28, 2015.

The repeat offenses were for failing to implement proper standard operating procedures with accurate information on safety systems and how they worked. Inspectors also found Pilgrim’s inspections and equipment testing were not completed as scheduled or documented as required.

The company, which faces penalties totaling $122,500, received serious citations for failing to use proper methods to prevent over-pressurization and explosions in the system and for placing the control and maintenance room facilities in the engine room for ammonia refrigeration.
