We use the combi-pok smoothbore nozzles, they have a sliding collar the when pulled back creates an impenging stream full fog pattern. This is set up as a protection system and with it not being at typical type fog it doesnt seem to move as much air. Might cut down on pulling the fire in? One question I ask to Scott is do you wear the HFD Reed hood?
I have heard some really great discussion on the subject of nozzle choice on flash-over, and can only surmise that there are some unresolved issues here which could cost some skin or life. I'm a west-coasty with three man companies and the old school combi nozzles or worse break-aparts. Our training comes mostly from the east coast experience, but takes a while to finally reach way out here on the fronteer. It seems that most agree that a smooth bore is the way to go if your fighting fire in a structure, which is also where flashovers ocurr. Puting enough water on the fire on the way in, and then if things go south in a hurry put more water before a flash. BUT my real question is this:
Why are you there? Did you actually do a size-up or just cowboy in the door ready to risk it all on this fire? Is there anyone inside near the fire who could survive the current heat and smoke conditions? Is the vent team in place before you decided to orphan your children for a structure the insurance company is already writing the check to replace?
The very best tool to use in a flash-over situation is between your ears! Don't put yourself into that situation. Use the experience of yourself and others to teach you when it is getting too hot, cool down the upper-levels with a smooth bore, ASK for the proper ventillation, and have an exit strategy which can be put into action within seconds. Never replace common sense with ego. Risk LIFE to SAVE LIFE. The best fire stories are the ones you tell yourself!
Bro- that seems like a terrible idea. What if you accidentally turn the nozzle so that the fog comes out also and you didn't want it to, as if you were crawling in with the line? Does the nozzle lend itself to doing that? Does it push the fire pretty well, as a fog would? Do you guys use it for interiro work, or exterior firefighting (wildland, car fires) where the fog would be helpful in radiant heat protection?
Please don't take this as bashing, I'm honestly curious. I'd like to try it for myself at the academy.
