Although Ammonia is stable on its own, it can form unstable compounds and even explosives, especially as it reacts with mercury, halogens, hypochlorites and nitrogen oxides. )N���6`�� ��yt�W�'�޺��c���XȔ���k��w�?��a'�-5T��V�@�2�����f��O1|��9O�a��s���|��H!X�G)e��X�T �Y’~�{�⭈K�̡��~�P Ammonia refrigeration works much like Industrial Refrigeration systems using synthetic refrigerants, with the major exception being that it uses anhydrous ammonia as the refrigerant. 6 0 obj Care must be taken to reduce corrosion, especially in wet and damp conditions and when metal temperatures are below the dew point. Under the Health and Safety at Work Act PCBUs with ammonia-based refrigeration systems at their workplaces have a duty to ensure, so far as is reasonably practicable, that the health and safety of their workers, and others (e.g. Emergency response - AEGLs AEGL-1 is the airborne concentration, expressed as parts per million or milligrams per cubic meter (ppm or mg/m3) of a substance above which it is predicted that the general population, including susceptible individuals, There is a risk of liquid Ammonia expanding and rupturing components of the system and escaping into the air. This document describes key safety measures that should be in place at any ammonia refrigeration facility. ���{�{�I���,���j��%���9��� ��0�Y&uyX�'Fs�N� It boils at an atmospheric pressure of -33. refrigeration system contains Ammonia in both liquid and gas forms. Ammonia is renowned for its favorable thermodynamic properties. It is extremely hard to ignite and is therefore very stable. endobj Ammonia Refrigeration Safety Inspection Checklist October 31, 2019 Issued in 1992, the Occupational Safety and Health Administration’s (OSHA) Process Safety Management (PSM) regulation is designed to give guidance to facilities regarding the … endobj Correct pressure cooling applications and systems it to become even more flammable unlike synthetic refrigerants specific temperatures is required industrial!
