@340wbymag it will still release ammonia, agreed. but it's not actually carrying vapor. that's the point i was trying to make. i agree about the runoff contamination being an issue.
Yes, you are correct about ammonium hydroxide. However, the water will continue to release ammonia vapor for a long time, and more water means greater runoff. A cloud can be better contained within a smaller area with a fine water fog, and there is far less run-off. I have done this many times.
do not spray water on a puddle of liquid anhydrous ammonia. you'll create a violent reaction, which is a bigger issue than you already have. spray water on vapor only. also remember that ammonia is colorless. the white fog you see is the water vapor in the air condensating from the low temp of the ammonia aerosol. just because you don't see fog in a room, don't assume the air is safe. you need more ammonia training than this to be efficient at responding to an incident.
@340wbymag the water does not carry ammonia vapor. once anhydrous ammonia mixes with water it is ammonium hydroxide. i fully agree on the runoff issue.
Firefighters always use FAR TOO MUCH water when fighting ammonia. This creates a problem with run-off, and the water carries away with it ammonia vapor which is released downstream. A super-fine mist creates much more water surface area and will absorb much more ammonia, while at the same time it creates a much smaller containment area and reduces run-off.

@340wbymag You speak the truth. I've seen it with my own eyes. Having to clean up after "cottonfield chemists" lol
