what is ammonia leak

Ammonia is a toxic gas or liquid that is used in manufacturing, refrigeration, and agriculture as a fertilizer. It is stored in closed pressurized containers, so leaks can occur when there are broken pipes and equipment. Even the smallest ammonia leak can be dangerous and even deadly. Exposure to ammonia at levels as low as five to 15 parts per million can cause irritation and discomfort. Ammonia is considered a high health hazard because it is corrosive to the skin, eyes, and lungs. Exposure to 300 parts per million (ppm) is immediately dangerous to life and health. Ammonia is also flammable at concentrations of approximately 15% to 28% by volume in air. When mixed with lubricating oils, its flammable concentration range is increased. It can explode if released in an enclosed space with a source of ignition present, or if a vessel containing anhydrous ammonia is exposed to fire.
