Have these guys never heard of halon systems?

Breaking the controls will make everything okay, instead of causing even more trouble.

I thought Halon was illegal to use in a closed room where people might be. The reasoning was that a person trapped in a burning room might be smothered with halon and die of suffocation before they get a chance to be burned alive by the fire. Maybe I'm remembering it wrong.

Mother-daughter talks always take place while doing the dishes, while father-son talks are usually done over a car with the hood up, or playing catch while standing about 5 feet apart.

IIRC, The original halon systems could suffocate people. I once worked in a lab where the fire suppression system would trigger an evacuation alarm prior to the fire retardant dump.

Where I now work, our server room has a more modern system which is allegedly safe for humans. Off hand, I can't remember what it is called.

The server room at a company I worked at years ago had oxygen masks in the room, and outside, too, if people wanted to go in to rescue someone, but mostly for if you'd breathed a lung-full of the stuff before getting out, and needed to clear your lungs.

I work in buildings with Halon Systems, they are triggered manualy from outside and there is a warning sign on the door.

I saw this again last night on a TV show. Maybe it bothers me more because it is technically incorrect.
I watched The Incredibles last night, and there the Parrs have a sprinkler system inside their suburban house. Is there such a thing?

And yes, the detection of smoke by a single sprinkler caused the entire house to get soaked.

The network guys? Yes. The network admin, his assistants, and fully half the progs could quote BOFH at least as well as they could quote Monty Python. (And one of those other progs was a hardcore Python fan and could quote entire movies.) It's probably just as well we didn't have Halon; too much temptation for the network admin to churn up certain middle managers.

In any case, bean counters don't listen to network guys about technology. Sprinklers and A-Class extinguishers are perfectly effective (read: cheapest) for IT houses. The arcing burns will fade and our own Medicare covers that anyway.

Man, I got stories about this outfit...

My youngest son and his wife own a townhome in San Diego. It has a sprinkler system inside. I don't know if it was mandatory for multifamily housing in California or just something the developer installed.

As for Halon, I used to work in a government facility that had several of those systems. Every now and then, one would misfire. No one was killed or injured. When they had a contest to name the installing dining facility, someone suggested the "Halon Dump". They choose "The Satellite Dish" instead.

Isn't Halon a chloroflorocarbon compound? I thought those were outlawed.

In the future, everybody dresses the same.

Sprinklers that I have seen work by heat, not smoke. The heat melts a wax 'bulb' that lets a valve spring open, that way only the sprinklers near a fire activate.

My friend Ragdoll set one off on her last day at school using a cigarette lighter, they knew it was her, she was the only one wet.

There are two movie cliches that get on my nerves:

1. "Watch Out Behind You!" Syndrome in horror movies, and

2. Women screaming and wussing out when they encounter the Really Scary Bad Guy. C'mon, get your courage up, gals!

Similarly, the scary thing will be right behind you when you tell somebody about it, and whenever you tell somebody's secret, they will be right behind you.
The main character will be scared by something harmless, then relax, which is when the real villian sneaks up on them.

Blasting the controls on the outside of the master villain's lair will open the door, while blasting them on the inside will seal the door.

Yes it is, and not it wasn't.
I used to work in the industry...It's been a long time, so some of my facts may be vague.

But; at the time R12 for cars was being phased out, Halon was being heavily taxed and regulated and went from a few dollars a pound to about 50 in about a year.

The fire industry made thier case for Halon by showing that it produced less damage to the environment than the burning of the objects that it protected.

I can't see how that can be, especially for something that is to remove the source of oxygen.
Although; "safe" may be the substance itself, and not the chemical or carcinegen effect it has.

Yes; our business didn't deal in those because they were up to the plumbers.

But; only because of the volume of that single sprinkler.

They only way you will get multiple sprinklers to go (besides all gettin the heat) is a "dry" system where all the sprinklers are open, and no water is in the pipe until something trips the system.

The fire suppressant used in our server room is something called FM-200.

According to this page, it is relatively safe stuff. Here is a link to the toxicity report summary if you are interested.

Interesting... a gas system that doesn't attack the oxygen side of the fire triangle.

I tried reading thier "how it works"... but:
Quote:
FM-200 removes heat energy from fire, not oxygen from the environment. FM-200 absorbs heat from the flame zone and interrupts the chemical chain reaction of the combustion process.
doesn't explain much.

Also, whenever a door opens in the villian's lair, smoke billows out. Beautifully parodied in Buzz Lightyear, The Movie.
