Annapolis Junction, Md. — An anhydrous ammonia leak from a refrigeration unit inside the warehouse at Taylor Farms Food Service here early Saturday, Dec. 1, brought out firefighters. Approximately 200 employees were evacuated, and three were evaluated by paramedics but refused transport. A Howard County DFRS special operations team was able to stop the leak, which was blamed on a failed gasket in a refrigerant piping system, and large fans were used to ventilate the warehouse.
