BOISE, Idaho (AP) — Federal authorities have fined an Idaho food processing company $273,000 following the release of a dangerous gas.

The Occupational Safety and Health Administration on Tuesday announced the fine against Dickinson Frozen Foods. Authorities say the large release of anhydrous ammonia in December 2015 at its eastern Idaho plant in Sugar City where it process potatoes didn't cause any injuries but other major ammonia releases at the facility have. Investigators say they issued 19 serious and two willful citations following the hazardous release at the plant with 220 workers.

Authorities say the plant lacks an adequate emergency response program and failed to equip employees with protective gear. The company, which has another plant in Fruitland, didn't immediately return a call from The Associated Press on Tuesday
