“a vast poisonous mist of a deadly chemical called anhydrous ammonia, typically used in cleaning products”
Uh, no. Anhydrous ammonia is not used in cleaning products - it is a gas at standard temperatures and pressures. In this form it can be used directly as a refrigeration gas, like Freon. I believe it can also be used as a fertilizer. Otherwise it is used as a feedstock for chemical processes, or hydrated to produce aqueous ammonia which can be used in cleaning products. Anyhydrous ammonia, much like hydrogen chloride or hydrogen sulfate, is particularly nasty because it turns to ammonia on contact with water, which the mucous membrames and lungs are full of (the latter two turn to hydrochloric and sulfuric acid, respectively). Result - instant chemical burns inside your lungs, which is not good.
Yup we used as fertilizer for corn for years. VERY NASTY STUFF!! Burns any tissue on contact.Really likes mucus membranes and other “wet” things.

The writer included material, which references anhydrous and aqueous ammonia, as well as their uses, that appears to have come from the company, .... for what it is worth. That seems to be the basis of his statement.
