Additional Items A. to a substantially reduced ammonia charge for their cold storagefacilities. Higher concentrations are easily detected. This page describes some inspection and testing procedures, work practices, and hose selection criteria to ensure the safe transfer of ammonia. Commercially, ammonia is made by combining free nitrogen and hydrogen gases under high pressure and temperature in the presence of a catalyst. The low ammonia charge is primarily achieved due to the elimination of the ammonia piping that runs to and from the central machinery room, and its associated large pressure vessels inherent in a central machinery room. Liquid ammonia is a clear fluid that evaporates quickly at room temperature. Ammonia is considered a high health hazard because it is corrosive to the skin, eyes, and lungs. ammonia. 26 0 obj <> endobj h�bbd``b`�� B H0ՁĄ�D03�X��b``�J�� Now with increased regulatory activity on fluorocarbon refrigerants (i.e., HCFCs and HFCs), even more interest has grown with ammonia as a refrigerant.. The liquid ammonia load-in app helps standardize Standard Operating Procedures (SOPs) for ammonium unloading, helping to minimize the risks associated with moving hazardous materials like ammonia. !�0� 0000002519 00000 n Wait about 10-15 minutes so that refrigerant settles down at liquid receiver.

Training 5. Ammonia is a natural refrigerant that has been used for many years in a variety of applications due to its high thermal efficiency. a stranded customer, as this will reduce battery life, especially if a battery is boost-charged more than once. special precautions must be taken when working with this chemical. Check the level of the liquid; if it is below the line, you have to charge refrigerant in it. startxref Refrigeration System Change Procedures A. xref B. Emergency response This manual contains only general information on the physical properties, storage, and handling of ammonia containers and relevant equipment. Ammonia is a gas with a distinctive pungent odour which can normally be detected by smell at concentrations as low as 5 parts per million (ppm). o�}bJ��$9 �$��K The process most commonly used is the Harber-Bosch method. Emergencies that can occur in an ammonia refrigeration facility range from minor emissions to ammonia releases of the type identified, evaluated, and managed as part of a Risk Management Program (40 CFR Part 68). Plans for testing and replacing safety equipment, such as monitors and alarm systems, detection equipment, radios, eye washes, respiratory and skin protection equipment, and first aid kits. followed by recommendations for handling the chemical and any paperwork needed in order to use the chemical in the laboratory. 0 Have a look at the sight glass which is attached at the side of the liquid receiver.
