Apparently at Air Transat's hangar at Pearson Toronto.

Awww...poor guys. Had to hit the button once. That stuff does stink and takes forever to clean up. The stink lasts a bit beyond forever. It does however, work.

You can see the, now, bankrupt Air Greek, or whatever they call it, in the background of the 3rd picture. Maybe it started to burn?

What happened, really?

Ah, OK, fire suppression system malfunctions:

I wouldn't like to be working in a restricted space, such as a fuel tank or underflow area and unable to evacuate swiftly, you would just be smothered and overwhelmed, it this an automatic event, or does someone have to press a button?

Both.......
It fairly low density and not toxic so you can still breathe.

Has anyone checked if the Lady Godiva Marching Band from U of T Engineering Soc was anywhere near the hangar? :ymdevil:

Foam on the range? I thought this thread might have been a rant on the culinary form......lentil foam wtf?

They are too busy with Frosh Week...

Remember that poor bastard in the Air Spray B-26 wing tank flash fire in Red Deer a few years back?

No, actually, and a search comes up with little on it.

zero fatalities..no word on injuries.

Didn't this system go off in some US military hangar which was full of Blackhawks ?

Good system though.

Ok, I thought the guy had died, he was badly burned. I forget the exact sequence of events, but he was working on a wing tank, enclosed space and all that, and apparently an electrical spark set the fire off.

Some time, long ago I was on a 150.00 tdw tanker built in Finland, it was fitted with the most modern Halon engine room fire fighting equipment available. It consisted of high pressure (50 bar if memory serves) spheres strategically located around the engine room, one was in the control room.
The system was remote activated and when the Chief Engineer, who had taken the boat out from the yard was going home on vacation, did a guided tour of his domaine with his replacement, he proudly opened the cabinet controlling this sophisticated equipment, pointed to a red button and said: "whatever you do, do not push this" and promptly pushed it.
All the Halon was released, a motorman sitting having a quiet cup of coffee in front of the nozzle on the sphere in the control room found himself wrong way up at the opposite side of the room.
With no total flooding fi-fi capability now available, the ship was no longer seaworthy, pulled in to Setubal in Portugal and had to wait for weeks for the correct Halon to be delivered.
One very expensive brain fart and one very red faced Chief.

I am surprised that the activating button would be "push". When I worked inside computer rooms with halon fire suppression systems the activating button (50 mm diameter) was a "pull" type and had a clear plastic cover that had to be lifted to activate the button.

That would probably be due to the increased hazards of halon fire suppression systems. A couple of seconds of extra thought before initiating.

Suffocation
High concentrations of halon can create an oxygen-deficient environment. This can cause people to suffocate.

Frostbite
Placing skin in contact with the liquid being sprayed from the extinguisher can cause chilled skin and frostbite.

Skin and Eye Irritation
Like most toxins, halon fire extinguishers can cause damage to eyes and skin. Irritation can occur even without direct contact with the halon.

Interruption of the Central Nervous System
Large amounts of halon gas that get inhaled can interfere with the proper function of the central nervous system. The symptoms of this are dizziness and a tingling sensation in the extremities, and in some cases victims will also go unconscious.

Cardiac Sensitization
Halon gas can cause irregular heartbeats and an increased heart rate in response to adrenaline. In extreme cases, this can result in a heart attack.

I'm sure they briefed you on all that. ?

There were other security measures in place, an alarm would go off in the engine room when you opened the cabinet containing the Red Button, but all overridden for demo purposes. One was supposed to vacate premises posthaste when the alarm sounded. On the other hand one was assured that unlike CO2, Halon was perfectly safe to breath.

Not nearly as bad as that, but... once when visiting a friend, I opened the toilet door and there was foam coming out of the pot. Just like that, slow but steady (not stinky, thank God). So, what do you do?
I stared numb, then closed the toilet door when the room was about half full. To keep it 'in there'.

The friends told (later) it sometimes happens. Didn't know why.
