There's another problem with this.  Neither acetic acid nor sodium bicarbonate are ammonia-based.  Ammonia is in cleaners, especially window cleaners, and certainly can make your eyes sting, but it is not involved in the reaction as described by Chief Belau.

..."I poured liquid plumber down the drain, two hours later I poured Runo down the drain and two hours later I poured another bottle of liquid plumber," says Hunter.

And that created a chemical so toxic, that even he didn't want us to go inside more than 12 hours later.

"It bubbled up started smoking and burning my eyes and I couldn't breathe so I got out of the house," says Hunter.

...We had Chief Belau demonstrate what can happen when acetic acid and sodium bicarbonate, both commonly used in household cleaners, are mixed together.

"You'll be able to see a chemical reaction as the two combine," he says.

Although this combination isn't toxic, it is poisonous.

"Anytime you mix an ammonia-based product with a bleach or an acid you get a bad chemical reaction...scratchy throat irritated eyes if you're exposed for too long you can develop something called Pulmonary Edema which is where the little air sacks in the lungs lead fluid and it causes trouble breathing," he says.

>Although this combination isn't toxic, it is poisonous.

HUH?
From merriam-webster.com* *for the definition of _toxic_: * "containing or being poisonous material especially when capable of causing death or serious debilitation"
