* 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.
