Having some kind of pipe marking system in place will help increase overall safety, reduce the chances of error, simplify emergency procedures, and minimize hazards. Safety Standards for Anhydrous Ammonia (Form Number 414-138-000) LAST UPDATED: 12/17/2015 This book contains rules for Safety Standards for anhydrous ammonia, as adopted under the Washington Industrial Safety and Health Act of 1973 (Chapter 49.17 RCW). System piping components With a notation whether the system is designed for underground or aboveground installation or both. The document shall be signed by a registered professional engineer or other person having special training or experience sufficient to permit him to form an opinion as to safety of the unit involved. If a liquid withdrawal line is installed in the bottom of a container, the connections thereto, including hose, shall not be lower than the lowest horizontal edge of the vehicle axle. When the cradle and the tank are not welded together suitable material shall be used between them to eliminate metal-to-metal friction. of anhydrous ammonia What It Is Standards provide requirements for the design, construction, ... and vapor fixed piping of the transfer system within 5 lineal feet or within reasonable distance of Anhydrous Ammonia - Responsibleag anhydrous ammonia system piping requirements and collections to check out. Read Online Anhydrous Ammonia System Piping … It is used and stored under high pressures, which requires specially designed and well-maintained equipment. All relief-valve discharge openings shall have suitable rain caps that will allow free discharge of the vapor and prevent entrance of water. The weak roof-to-shell seam is not to be considered as providing any of the capacity required in (a) of this subdivision. A suitable "hold down" device shall be provided which will anchor the container to the vehicle at one or more places on each side of the container. �&. When the surface area is not stamped on the nameplate or when the marking is not legible the area can be calculated by using one of the following formulas: Flow Rate - CFM Air = cubic feet per minute of air required at standard conditions, 60 deg. A hydrostatic relief valve shall be installed between each pair of valves in the liquid ammonia piping or hose where liquid may be trapped so as to relieve into the atmosphere at a safe location. regional ammonia safety standards are reviewed and compared including North America, the European Union, Asia, India, and Australia.
