Iron and steel recommended. In presence of tr amounts of water, NH3 vigorously attacks Cu, Ag, Zn, and their alloys. Combines with Hg to form explosive compounds.

Noncorrosive; most common structural materials can be used.

* Strong oxidizer, regarded as non-toxic, but exposure to high concentrations adversely affects pulmonary and central nervous systems. Supoprts and vigorously accelerates combustion; avoid all contact with oil, grease, or other combustible or flammable materials.

** At high pressure can accelerate the burning of combustible and flammable materials.
