Sounds like Flying Dog is having some issues tonight. I've heard a couple of calls go our over the police scanner now, must be a pretty bad incident. Something about an active hazmat incident and a visible ammonia cloud. What would ammonia be used for? Refrigerant?
Never heard of ammonia in that context, but when I was living in Puerto Rico in the 1970's there were rumours that some beers (notably Rheingold and the old Brooklyn-brewed Schaefer - still much missed) sent from NYC-area breweries to Puerto Rico contained formaldehyde as a preservative (didn't notice any in the taste, though).
