This document describes key safety measures that should be in place at any ammonia refrigeration facility. Ammonia Refrigeration Best Practices – Online Click Here To Register Today. In industry, ammonia is used in petroleum refining, to manufacture pharmaceuticals, to disinfect water, and as a refrigerant. Ammonia is also flammable at concentrations of approximately 15% to 28% by volume in air. 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. A tragic example of this took place in British Columbia in 2017, when a pinhole in an ice rink brine chiller allowed Ammonia and brine to mix. The Department of Transportation classifies it as a non-flammable compressed gas. Unlike synthetic refrigerants like CFCs, it doesnt damage the ozone layer. 2 0 obj 13 0 obj <> members of the public) is not put at risk from the release of ammonia. 8 0 obj Industrial Ammonia Refrigeration systems have components such as compressors, piping and vessels which are designed to contain ammonia at the correct pressure.

Refrigerant grade anhydrous ammonia is a clear, colorless gas or liquid and about 99.95% pure. When working in the industrial ammonia refrigeration field, it’s vital employees know potential safety hazards and proper safety procedures in the event an accident occurs. Ammonia refrigeration companies like Industrial Refrigerated Systems Ltd. provide, for various cooling applications and systems. Insulation does make a difference; however, if insulation is defective or incomplete, condensation will not be prevented and corrosion will not only occur but possibly be hastened. 4 0 obj Most of ammonias potential for harm relies on there being too much of it in one place, not on its being leaked and scattered into the environment. {7q�3�_�!��U�"��K0��?h� }�����2���:l��X�m5Q�C�hiW(6O� }���4S�1�X�xB� 5�]R����`ZB�����}�M�6�Gd� �ה��]���#���IUit[M� 7]�->2 WLG"�%�^�1y�n��hC�3�d�&N)�Ę�������Dv4ͳ'�c}?��d�ۊx]$���� �g�cI@U���H�]R��e�q�Xǵ�ucL��߱(�?����::�U_�2�g@W�*�0N�n�İα[@���NtWJpɄ��1�黂([��"�\Ν��UR�'��aק�/���;(N��6.N �~���^����_|����.ZR�pj�a��1�?��O��H�cG�����`t)))��ơ��0ҽ���������;�"S�7V�O�ʮm�dfp[*�s����c+삪���ƹo 7 0 obj DRAFT Final Dec. 6, 2019 6 . <> 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 … Understanding how it works, and how to use it safely is critical.
