Ammonia leak caused by strainer gasket failure in food processing facility

A small ammonia leak occurred at an industrial food processing facility used to freeze poultry. The compressor was shut down by the shift operating engineer and the plant was evacuated. After the ammonia had dissipated and the ammonia detection system’s reading dropped to 0 parts per million (PPM), the repair was completed by the contractor. The plant was then restarted without any leaks being observed.
