A case of ammonia poisoning occurred when refrigerant ammonia leaked from a refrigeration unit and flowed into a meat processing plant.
Due to a malfunction of the electromagnetic valve in the cooling system of the meat processing plant, the compressor in the refrigeration unit was damaged, causing ammonia gas to flow and spread within the factory. After ventilating and evacuating the ammonia gas, work commenced, but due to insufficient removal of the ammonia gas, secondary damage occurred in the form of ammonia poisoning. Additionally, a maintenance worker who came into contact with a low-temperature object while closing the valve of the refrigeration unit suffered frostbite on their toes. 【Suggestions】 ■ By using gas detectors during regular patrol inspections, it is effective for confirming the safety of workers and for the early detection of ammonia gas leaks. *For more details, please refer to the PDF document or feel free to contact us.
