    Hey - a friend of mine who deals with antiques just acquired a couple of the original style "extinguisher grenades." I can connect you up with him if you're interested.....

    995.00 a piece sounds like a masterguard product???

    Thanks for the replies. If I remember right you have always been very critical of this thing, so I knew I would get some honest answers from you.

    I know you said that you were waiting in the hallway, my guess would be that you had the benefit of a charged hose line next to you with a safety line as an additional backup. With that in mind let me ask you these question:

    1) I know that the only way I would ever consider this tool useful, and it sounds like you feel the same way, is for an initial unit that is unable to make an actual attack the good old fashioned way (ie: Chiefs unit). Unless it is a confirmed victim situation I would not advocate entering the house without the benefit of a hoseline. So that would probably prohibit the same deployment situation that you had. (Being able to deploy from a hallway). Since I am just going by hearsay, and you have actually seen this thing for real now, am I correct in my thoughts here?

    I agree with the usage being primarily from an in initial unit, like a Chief's buggy. I agree that there is more danger in entering without the protection of a hoseline. I would suppose a prudent person would size up the situation and determine if an interior deployment was possible. If not I would punch the smallest hole in the window possible for deployment.

    2) Based on #1 I would think the only practical deployment would be through a window. I know you said that you think the performance might have suffered because you guys were unable to completely isolate the compartment. Do you think that a room with the door closed and a (now) open window would perform similar? How much do you think having an open door and a (now) open window would further degrade the performance?

    Door closed / window deployment: As I said above, I personally, would make the window hole a s small as possible. Open door / window deployment: Again as small an opeing in the window and deploy through the window.

    My feeling is the window / closed door deployment would be superior because of more enclosed space. Window / open door I feel it would knock down the fire, but perhaps not as much or hold it as long due to dispersing of the chemical agent. REALIZE THESE ARE JUST MY OPINION.


    3) If we cannot use it without a hoseline and it is a non-rescue situation, do you think it is a beneficial product if the fire is in a "central" location? For example an interior bathroom with no outside windows? Do you feel like it is worth trying to make access to the interior room to deploy, or would it be better to wait for traditional staffing and units to make an attack even if it means a longer burn time?

    If conditions allow yes I do believe it would be beneficiaql and if conditions allow an attempt MIGHT be made.

    ALWAYS smart to have a hoseline with you.


    4) Assuming an "interior burning compartment" and a confirmed victim: Lets say that only 1 or 2 firefighters are first on scene without a hoseline. I know that the FIT is not supposed to be used in compartments with victims. But what if the room next to the victim is on fire? Do you think there would be any benefit from grapping the FIT and tossing it into the compartment room to maybe buy you an extra minute while you grap the victim in another room?

    From what I saw, I would definitely say that it could buy you the time to attempt a rescue.

    5) And yes, I am actually going to try and ask some questions to a guy who I am pretty sure is not a salesman and has actually used it in order to keep an open mind.

    I am no slaesman, not a factory rep, and I have absolutely nothing to gain other tham disseminating information based on my personal experience and observations.

  • DSPA: Dry Sprinkler Powder Aerosol, FIT: Fire Intervention Tool

    Okay, I finally got to see one of these things in action. This is the latest incarnation of the FIT-5.

    I was teaching at the Northern Illinois Southern Wisconsin Fire Rescue Association Fire School in Monroe and our class involved live fire training in house trailers. We had an end bedroom set up with 2 bails of hay and 2 pallets. We ignited the fire and let it get to the point that fire was rolling heavy across the ceiling and much of the room was involved in fire. We were positioned in the hallway just outside the bedroom. The salesman activated the FIT and tossed it in the room. It failed to activate. The salesman activated the second FIT and tossed it into the room. Within roughly 10 seconds it activated and the entire room was full of dry chemical dust. The fire was immediately knocked down. Not out, but knocked down. The room was filled with the dust from floor to ceiling and wall to wall. Because there was no door for the bedroom it was not possible to entirely isolate the bedroom. After roughly minute I got up and ventilated the room, at that point the fire came back pretty quickly.


    My conclusions are as follows:

    1) Under the right circumstances this could be a valuable way to buy time while waiting for fire apparatus to arrive. Such as in a chief's buggy.

    2) The failure of the first device to activate was a little unsettling. The salesman admitted the triggering device had been problematic and these devices were old stock and all the new manufactured devices have a new trggering device and according to him the reliability issues have been resolved.

    3) I believe being able to control the openings is crucial to the effectiveness of this device. In other words the tighter closed you can keep the area of deployment the more effective it will be.

    4) Cost is still a concern at $995 per unit. It has dropped from its original cost of around $1500. But is still quite pricey. But...if you balance the cost against saving someone's house perhaps it isn't such a bad deal after all.

    5) I visualize this primarily being used in more suburban, or rural, situations where response of fire apparatus may be delayed due to staffing issues or travel time to remote areas of the district.

    6) The salespeople made it clear they would be happy to come out to my FD to demonstrate this device when and if we had a practice house burn in our area.



    I am not over being skeptical but I am more open minded to the possibilities that this tool may have some practical use in some specific cases.
