Ammonia release leads frozen food manufacturer to $273K penalty

Company allegedly lacked adequate emergency response program and training

Posted June 10, 2016

OSHA found an Idaho frozen food manufacturer failed to safeguard employees and was unprepared to respond to a potentially lethal release of 1,300 lbs. of anhydrous ammonia on December 1, 2015.

While no one died or suffered injury in the December incident, other major ammonia releases at the company have hospitalized employees at another facility in the past. In its review of the latest incident, federal investigators found the company lacked an adequate emergency response program and training, and failed to equip employees with protective clothing and respirators.

OSHA investigators issued 19 serious and two willful citations following the hazardous release. The agency has fined the company a total of $273,000. A recent OSHA investigation after the incident uncovered dozens of hazards related to emergency response, respiratory protection, and process safety management of hazardous materials violations.

Anhydrous ammonia is a colorless gas with a distinctively pungent odor that is widely used in agricultural and industrial refrigeration systems. The ammonia vapor severely irritates and can easily damage the eyes and respiratory tract. Mixtures with certain other chemicals can produce violent reactions and explosions.

OSHA found numerous violations during its inspection, including:

  • Failure to maintain a “process safety management plan” that spells out a framework for any use, storage, handling, or movement of highly hazardous chemicals.
  • Employees exposed to liquid ammonia without chemical protective clothing.
  • Employees entered a potentially life-threatening atmosphere without self-contained breathing apparatus.
  • Employees were not medically evaluated or fit tested to wear respirators.
  • Employees were not trained on the facility's emergency response plan when they were hired and when they changed positions.
  • Employees responded to an emergency without proper emergency response training.
  • The employer did not evaluate respiratory hazards during the ammonia leak response.

OSHA investigators have inspected the company’s facilities several times since 2009, citing the company for serious violations of fall hazards, respiratory hazards, confined space, emergency exits, and response procedures.

The company has 15 business days from receipt of the citations and proposed penalties to comply, request an informal conference with OSHA's area director, or contest the finding before the independent Occupational Safety and Health Review Commission.
