Ammonia (NH3) is pungent, colorless compound. Anhydrous
(water-free) ammonia is easily liquefied under pressure and is
extremely soluble in water. Ammonia is the precursor to most
nitrogen-containing compounds. Virtually all synthetic nitrogen
compounds are derived from ammonia, including nitric acid, which is
used in the production of fertilizers, explosives, and many
organo-nitrogen compounds. It is easily liquefied by compression or
cooling for use in refrigeration and air-conditioning equipment.
Because of its many applications, ammonia is one of the most highly
produced inorganic chemicals, yet it is both caustic and hazardous.
OSHA has set a limit of *5 ppm during an eight-hour shift. EPA
regulations (*0 CFR *8) require facilities with more than *0,**0
pounds of ammonia to submit a risk management plan,
including a hazard assessment, a prevention program, and
emergency response program. Technical
