Talked to a former warehouse worker this morning who I knew had been exposed to an ammonia cloud. His experience bears out exactly what I'd read or been told previously. Instant intense burning and coughing had everyone running away asap, and (his words) " ... only Chuck Norris or a retard would stand in the cloud long enough to choke out if there was a way out."
And troopers aren't
generally known to be either, entirely.
