i just checked over at another ems forum where this was posted, and the op (and subsequent comments) are all under the impression that it is real.
not sayin your wrong linuss, either way this is an important reminder for scene safety.
It's a good training video, as mentioned. Ammonia doesn't incapacitate that quickly. It certainly can incapacitate, as it reacts with the water in the tissues of the trachea, bronchi, alveoli, and so on, and as the tissue breaks down more and more water is released to increase the reaction. But the severe burning in the eyes, mouth, throat, etc has most people scattering quickly before severe damage sets in. He wouldn't have just walked into a cloud and keeled over.
Good point made in the video, though. Always remember ... "Scene safe? BSI."
well real or otherwise it's an important reminder to emergency personnel.
here are the state trooper's errors:
- not backing away to a safe distance once the vapor became visible
- assuming it was smoke when signs pointed to something much more sinister: white vapor, large tank leaking, and unconscious person laying in the middle of the road
- running to help when he should have waited for fire to clear the scene
Fire department didn't do a very good job either:
- parked way too close to the vapor, even when the body of the state trooper they just talked to was right there
- didn't put protective gear on in the rig. what if it was a corrosive substance?
at least they came out with their BA's on, but if they had parked any closer the whole thing would go from tragedy to clusterfudge.
the ambulance crew did the sensible thing by staying away from the contaminated scene. but dont tell me that half the emts in this country would be scrambling to help just like the trooper did.
If you seriously think ammonia doesn't capacitate that quickly, you may not have inhaled any. I have done it once while working on a farm. Once breath knocked the tar out of me and had me scrambling for fresh air. The trooper in this video, whether it was real or staged, was breathing the ammonia for plenty of time to constrict the lungs and make him unresponsive.
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.
