PN10942 Version 2 Last updated February 2018 - Emergency planning for ammonia-based refrigeration systems guide Page 4 of 19 Introduction Under the Work Health and Safety Act 2011 (WHS Act), all workplaces must prepare an effective emergency plan for the workplace. The most common symptoms experienced as a result of an ammonia leak are skin and eye irritation, respiratory irritation, and coughing. 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. endstream endobj 27 0 obj <> endobj 28 0 obj <>/Encoding<>>>>> endobj 29 0 obj <> endobj 30 0 obj <>/ColorSpace<>/Font<>/ProcSet[/PDF/Text/ImageC]/ExtGState<>>> endobj 31 0 obj <> endobj 32 0 obj <> endobj 33 0 obj [/ICCBased 39 0 R] endobj 34 0 obj <> endobj 35 0 obj <> endobj 36 0 obj <> endobj 37 0 obj <>stream H��W�r�F}�W�#�%A�_�6��8�D)��79cpH� �p#���===or�eKU683���>}���Թ�NC startxref Ammonia is highly toxic to fish. h��Sߋ1�W�X�$�_8��l��{�iЀ�����w&����E�X�lfg&3߷_F�A�2� jņ%ñ�@W� ������[�o�n�� �?���hW��ø���ršJܥ.��x� h2�u;l�n��j��8y,�q^'䆊�})��q�D0�����i�c�ϺnFJ��)&).r�%>����ŴM�o�U��ܥR�Q������#x���{@���u��yoۏ���[�Y��u�O��o��*�_؞;0)]HM�9��+1=� �(�N(:��EP2�� y ��/��ꆦP��� ==��˓\)�4q��P�(�� � �o``g��� �=�,����o�;d�Ø{��I�����$�JC��s* Most ammonia leaks are small and do not pose serious health risks. Ammonia Charging Hose For ammonia. The user must be alert to signs of hose deterioration before failure occurs. safety laws for anhydrous ammonia refrigeration system operators. followed by recommendations for handling the chemical and any paperwork needed in order to use the chemical in the laboratory. !�0� In order to charge the system, the ammonia installer needs to connect a charging line to the ammonia refrigeration system using the appropriate valve. 4. Refrigeration System Change Procedures A. 2.2This standard shall apply only to closed- circuit mechanical refrigerating systems utilizing ammonia as the refrigerant. 0 Boost charging is not recommended except in exceptional circumstances e.g. Open the charging cylinder hand valve and dump in the refrigerant into both the high and low side of the system. It is not intended to replace or limit safety procedures in your facility. 0000008246 00000 n Ammonia system shutdown operations are another circumstance during which improper procedures can result in a release. %PDF-1.5 %���� This manual contains only general information on the physical properties, storage, and handling of ammonia containers and relevant equipment. The reefer plant is a combination of various machines such as compressor, valves, heat exchangers etc., which are connected to each other through pipes and joints.

Subtract the refrigerant system charge from the amount of refrigerant in the cylinder and mark the level using a rubber band on the barrel.

Ammonia (R-717) has been a longtime, popular refrigerant choice in industrial facilities, such as cold storage warehouses, food processing plants, and chemical manufacturing plants. Hoses used for loading or unloading ammonia into or from the refrigeration system have a limited life. For this reason, ammonia is classified as very toxic to aquatic life. Already the concentration of 1 mg/l may kill fish. <<6A9FC5C92F5FE64F93ECDA9015A48D2A>]>> 26 0 obj <> endobj 2.3This document does not address the 0 Emergency response 0000059365 00000 n Exposure to 300 ppm is immediately dangerous to life and health.
