Ammonia inhalation is best described as which type of chemical?

• A. Corrosive or irritating gas
• B. Inert gas
• C. Liquid solvent
• D. Flammable vapor

Answer: (A)

Ammonia inhalation is best described as a corrosive or irritating gas. Ammonia is a sharp, highly water-soluble gas that, when it comes into contact with moisture in the eyes, nose, and airways, forms ammonium hydroxide and causes chemical irritation and burns to mucous membranes. That irritation can lead to coughing, choking, wheezing, and potentially airway edema with more exposure. This distinguishes it from an inert gas, which would not irritate tissues; from a liquid solvent exposure, which implies a liquid contact rather than a gaseous inhalation hazard; and from a flammable vapor, where ignition risk would be the primary concern rather than tissue irritation.
