Hmm . . . Anhydrous ammonia, a colorless gas with pungent, suffocating fumes, is used as an agricultural fertilizer and industrial refrigerant.

When handled improperly, anhydrous ammonia can be immediately dangerous to life or health. As liquid anhydrous ammonia is released from its container into the air, it expands rapidly, forming a large cloud that acts like a heavier-than-air gas for a period of time. Because the vapors hug the ground initially, the chances for humans to be exposed are greater than with other gases. Symptoms of anhydrous ammonia exposure include:

eye, nose, and throat irritation
breathing difficulty, wheezing, or chest pain
pulmonary edema, pink frothy sputum
burns, blisters and frostbite.
Exposure can be fatal at high concentrations.

Anhydrous ammonia is also a key ingredient in the production of methamphetamine (meth), an illicit activity frequently occurring in makeshift laboratories.  (CDC)
