    Question positive pressure ventilation

    my question is to how many dept's use ppv at structure fires compared to negitive pressure and is it used for entry or just ventilation and your thoughts on one verses the other? ( yes i did a search and nothing was found)

    You might want to try your search again. This topic has been hashed out several times in this forum. I did a search and found quite a few threads with this topic. Some people use PPV and love it and others don't use it and never will. I believe it could be helpful in certain situations, but it can be very dangerous.
    Just someone trying to help! (And by the way....Thanks for YOUR help!)

    Aggressive does not have to equal stupid.

    Default I love it

    In my opinion PPV is the most misunderstood/underused tool we have in the fire service.Most all the myths about how dangerous it is have been proven false by studies done in different departments.Tempest has a great video that discusses its use by Salt Lake FD which is real informative.Its a great place to start if you want information on using PPV.

    I love the ppv fight! We never use it, never will. Totally unneeded tactic.

    We use it after the fires out. We do not use it during an initial attack. PPV is a great tool that has its time and place. We use it to clear out smoke... After the windows are out and the roof is opened (when necessary). This a lot like CAFS. You do what works best for you.

    Ok 4th and Fred. I know that the CFD has a PPV unit. How about FDNY? I can't see how anyone can be against a piece of equipment. Maybe the way said equipment is used. But come on 4th, have you ever even used a fan? (Not the ones who bring you coffee cakes)

    Maybe in your area, and with your particular modus operandi, but it works in some places, in some situations. Works for us.

    Are you talking about that giant one on the back of a truck? 48" or something close to it. I think they got that for the subway but I dont know if it has ever been used. We also have 2 smoke ejector trucks that might get used once a year each. Other than that, no, I have never even seen a ppv fan. Have you ever seen one in the city? I don't think we even have any.

    Red face opening old wound

    gentilmen, i stand corrected!
    i ran a search and no hits came up under positive pressure ventilation ,sorry for the overload !!

    but while on the subject i must say i use ppv for ventilation all the time to clear a structure but not for entry. once the fire has been found and knocked down ppv is started right away while interior ventilation continues. it has been a real asset removing smoke, gases and co 10 times faster than negetive ventilation creating a safer environment for our firefighters.

    THANKS FOR THE REPLYS !!

    We use PPV, hand in hand with fire attack. It is very effective in clearing the smoke and heat allowing you to get to the fire quicker. Reduces the chance of flashover and ventilation is accomplished quicker. Just remember your exit opening. But we don't use it in all situations,because every situation is different.
