What is anhydrous ammonia?
Anhydrous ammonia, or NH3, is a clear, colorless gas. It is also a liquid if stored under pressure, according to the CDC. It’s a toxic gas or liquid that is corrosive if concentrated.
Normally, the chemical is used in agriculture as a fertilizer, as well as refrigeration in retail grocery stores, and manufacturing.
This type of ammonia is much less concentrated than the common household ammonia. It rarely causes burns but it does cause irritation.
Why is it dangerous?
Anhydrous means “without water,” meaning it aggressively seeks out moisture such as soil, or your eyes, skin, and/or lungs. The chemical can also be dangerous if not handled properly.
What should I do if I’m exposed to this chemical?
According to Dr. Erika Brown with Harris County Public Health Department, if you experience any of the following symptoms, seek emergency care immediately:
- Watery, burning eyes,
- Irritation of the nose and throat
- Headaches
- Shortness of breath
- Dehydration
- Caustic burns
- Frostbite
