Why hasn't anyone invented a "halon bomb" or "grenade" for firefighting use.
Halon sucks the O2 from the air and starves fires. Commonly used in offices and server rooms instead of water. Also used in most military vehicles. Why not deploy a halon bomb/grenades into a structure that is known to be unoccupied? |

Halon is a CFC and production stopped in the early 1990's IIRC. Supply today is merely recycled.
Halon is usually stored as liquid, and pressurized and sent through suppression equipment as a gas. So that would be a substantial endeavor for something like you are describing. |

Fire grenades have been around for ahwile. The fit 5 is new seems kinda cool.
fire grenades |

Halon was useless outside of confined spaces.
It worked fine in computer rooms, offices etc. But for other structure, vehicle and roof fires it couldn't be used effectively. Great for a boat engine room, in a car or truck it would just pass through the engine compartment. |

Similar to how dry chemical works but with a 'clean' gas instead of a messy powder. Halon systems do not rely on O2 depletion like the CO2 total flood systems do. The FIT-5 thing is a joke. |

There was talk of doing a demo at the fire academy but that has yet to happen I have no personal experience with them. But at least this tech is still being developed. |

A little over $1K a pop kind of kills it coming out of the gate. It is billed as a easy way to slow/stop incipient stage fires in structures by tossing it in a window/door before the hose lines are ready to go. If you really want to do dry chem on a structure fire for $450 you could get a 30lb ABC that would have the same effect if was shot through the window. It is a tossable dry chem extinguisher, might be useful to toss in a basement window if you can afford it. Most of the demos show it in a situation that a 20lb ABC could also slow the fire spread down. I don't see what's worth $1K about it. |
| Unfortunately I'm not sure what it cost. I was pretty new when we got it and was not privy to that sort of info at the time. I will say this though, we have had it for about 4-5 years and to my knowledge, it has never been used. We are a suburban combination department and the fires are usually small enough to handle with an extinguisher or big enough to not make waiting an extra minute for an engine a game changer. |

For that kind of money it's nuts, and most guys are shocked at how much work you can get done with a good can man. I do like the development of tech for non trained personal. |

Some people flip out at the mention of going interior with a can like that. Even with how long FDNY has been doing it with great results. It is like some people's blind hate for the booster line. |

Probably where my use of the can was instilled, I also notice that newer guys always go for the preconnect but the older guys will grab the booster quick. My house uses both but I have covered others with officers/FF that are against the booster for anything but washup |

I don't have blind hate for a booster line, I'd just rather have an 1 3/4 if I'm going interior. A neighboring company uses 2" attack lines  .
I think some people just don't realize that they don't know how to effectively attack. If you start flowing water around the first second you see smoke of course you're going to use more water than you need. |

One of our local departments had one of the first deployments on a basement fire and they raved about how great it was...dunno...haven't heard much since then... |

Why some depts would rather pull a cross lay for a little highway median grass fire is wacko. Unless they roll CDF style with the shorty bumper 'whip it' line.
