Permanent damage can result. Handling It Safely Anhydrous ammonia can be used as safely as any other gas or liquid that is handled under pressure. But you must be alert to prevent accidents. One good thing about ammonia is that its sharp, irritating odor is an excellent warning. You'll know right away when it is around.
Most accidents happen when ammonia is being moved from one tank to another.
Defective hoses also allow ammonia to escape without warning. Use the proper equipment. Be sure there are no copper, brass or galvanized parts, since ammonia will corrode them. A tube or fitting weakened by corrosion can burst. Take care of your equipment Inspect it regularly to keep hoses and valves in good shape and all connections tight.
