Exposure to high levels of ammonia may hurt your skin, eyes, throat, and lungs and cause coughing and burns. Lung damage and death may occur after exposure to very high levels of ammonia.

Inhalation of ammonia may cause nasopharyngeal and tracheal burns, bronchiolar and alveolar edema, and airway destruction resulting in respiratory distress or failure. Ammonia's odor threshold is sufficiently low to acutely provide adequate warning of its presence (odor threshold = 5 ppm; OSHA PEL = 50 ppm).

Ammonia is a colorless gas that people may be exposed to in certain industrial or agricultural settings. High levels of ammonia can be harmful. Inhaling ammonia may cause damage to the lungs and respiratory tract. Inhaling ammonia may cause coughing, burning in the throat, and difficulty breathing.

Ammonia gas in a confined space can be a fire and explosion hazard. It can decompose at high temperatures forming very flammable hydrogen gas. Ammonia is fatal if inhaled and corrosive to the respiratory tract. Its corrosive properties cause severe skin burns and eye damage.
