The user has the responsibility to take appropriate safety and health protection measures and to ensure the compliance of national related laws and regulations. Liquefied anhydrous ammonia is highly toxic and is corrosive to the skin, mucous membrane and eyes. Contacting liquefied anhydrous ammonia can cause severe burns. It shall have proper protection during the operation. 1 Scope This Standard specifies the requirements, test methods, inspection rules, packaging, mark, storage, transportation and safety requirements for liquefied anhydrous ammonia. This Standard is mainly applicable to the liquefied anhydrous ammonia (liquefied ammonia for short) which is prepared by the direct catalyzed synthesis of hydrogen and nitrogen under the condition of high temperature and high pressure. The Standard is also suitable for the products which are produced by other processes. 2 Normative references The following documents are essential to the application of this document. For the dated documents, only the versions with the dates indicated are applicable to this document; for the undated documents, only the latest version (including all the amendments) are applicable to this standard.

The allowable weight filling coefficient is 0.53kg/L. The steel cylinders or the tanker shall have the purification treatments such as water-washing and drying at regular intervals. 7.2 The steel cylinder of oxygen or chlorine gas and all copper-containing vessels must not be used to fill liquefied ammonia. 7.3 For the tanker which is filled with liquefied ammonia for the first time, it shall have the treatment of vacuuming or the nitrogen-charge-replacement. The vessel which has previously been filled with liquefied ammonia shall be air-exhausted before the filling. The evacuation steps shall be according to the provisions in TSG R4002. 7.4 The outer-wall of the steel cylinder and tanker which are filled with the liquefied ammonia shall be painted with yellow paint. 7.5 It shall be according to the "toxic gas" in GB 190 to mark. 7.6 The steel cylinder of liquefied ammonia shall be stored in the dedicated storage room or the open-air tent platform, so as to prevent the direct sunlight or the rain. 7.7 The cylinders and tankers for the load-transport of liquefied ammonia shall comply with the requirements of JT 617. Avoid heating and strictly prohibit the fireworks during transportation. The steel cylinder shall have safety helmet. The exterior of the steel cylinder shall be bound up with rubber rings or straw ropes, so as to prevent the intense impact and ......
