Sets out requirements for the design, construction and location for installations ranging from bulk depots to points of usage or application. Also deals with safety procedures associated with the operation of an installation, transport and utilization.

This Standard sets out requirements for the design, construction and operation of equipment and installations for the storage and handling of anhydrous ammonia, and for its transport by road and rail. It does not deal with any plant or equipment in which ammonia is processed, or with any vessels that form an integral part of that processing equipment.
