Responding to a report of workers being exposed to anhydrous ammonia, federal investigators found a Madison ice cream plant lacked sufficient process safety management procedures to control the release of hazardous chemicals. Exposure to anhydrous ammonia, used in the refrigeration process, can cause respiratory injuries and burns to the skin and eyes.

OSHA investigators determined AJLS Enterprises Inc. ‒ operating as Schoep’s Ice Cream ‒ failed to document that equipment was being operated consistently with best engineering processes, update processes following audits, and respond to changes in the process.

OSHA issued 12 serious citations and proposed $145,097 in penalties. In addition to insufficient process safety procedures, OSHA noted multiple safety and health violations, including:

  • Lack of lockout/tagout procedures.
  • Lack of machine guarding.
  • Failing to train workers in lockout/tagout procedures.
  • Not having a written hazard communication plan.
  • Failing to update the emergency action plan.
  • Ladder openings not protected from fall hazards.
