Summary: The American National Standards Institute (ANSI), Safety Requirements for the Storage and Handling of Anhydrous Ammonia, publication No. K61.1–1981, is a guideline established for authorities charged with regulating the storage, transportation and handling of anhydrous ammonia. These requirements apply to the design, construction, repair, alteration, location, installation or operation of anhydrous ammonia systems including refrigerated ammonia storage systems. However, these requirements do not apply to ammonia manufacturing plants, refrigeration plants where ammonia is used solely as a refrigerant or ammonia transportation pipelines.

2. (2) Should any portion of ANSI K61.1–1981 be deemed unacceptable, rules will be promulgated within this chapter denoting and excepting those portions and adopting alternative provisions as deemed necessary by the director of the Department of Agriculture. 2 CSR 90-11

Cylinder and other portable container valves and other fittings, or hoses attached thereto, used in anhydrous ammonia service, shall be constructed of material resistant to anhydrous ammonia and shall not be constructed of brass, copper, silver, zinc or other material subject to attack by ammonia. Each cylinder utilized for the storage and transportation of anhydrous ammonia shall be labeled, in a conspicuous location, with the words “ANHYDROUS AMMONIA” or “CAUTION: ANHYDROUS AMMONIA” and the UN number 1005 (UN 1005).
