- IDLH is a maximum concentration of ammonia at which a worker could escape without injury or irreversible health effects. The IDLH for ammonia is 300 ppm. A short exposure of 400-700 ppm will cause severe eye, ear, nose and throat irritation but with no lasting effects.
- Coughing and bronchial spasms will occur at 1700 ppm.
- 30 minute exposure at 2000 to 3000 ppm may be fatal.
- Rapidly fatal due to serious edema, strangulation, and asphyxia at 5,000 to 10,000 ppm. Fatal at 10,000 ppm or 1% by volume.

Vapor concentrations of 10,000 ppm (1%) are mildly irritating to the moist skin while 30,000 + ppm may cause skin burns.
