It makes the fire worse, but it also clears the smoke which is a good thing because fire fighters can see where they are going, and casualties have more air to breath. :)

mmm... have to admit it can make the fire worse... if used incorrectly.

on the other hand, if ventilation is conducted properly and closeto the seat of the fire, they can be excellent and greatly assist the containment and extinguishment of the fire...

definitley excellent equipment for salvag/overhaul ops...

I was saying they were a good thing, even though they can make the fire worse... how is that bashing technology?

sorry CFS_firey, I just looked at the comment  It makes the fire worse
I have been on CFS courses and talked to members from other brigades and they just hate PPV ( funny none of them have used a PPV)
It if you use the comment It makes the fire worsewithout saying why people get the wrong idea about the concept

Sorry, I should probably clarify then:

PPV Fans introduce more oxygen to the fire, so the fire will burn better and larger, but by using the PPV fan (Correctly) you will remove smoke and heat from the building, allowing you to access the fire easily and quickly, and extinguish it.  With the fire burning more brightly, it is also easier to find.

So even though the fire is getting bigger, its aiding us when it does.

Without proper ventilation and positioning, PPV fans CAN screw things up.

In all cases I have found that premature introduction of a PPV Fan has hindered the fire/rescue operation and overall extinguishment of the fire.  It is often amusing to see how incorrectly they are placed even for ventilation during salvage etc..

If you know what you are doing they can save alot of time and damage during a fire, but there are so many probabilities that can go wrong, it is often a very hard call to introduce the fan until the fire has been extinguished..

But, a key piece of equipment in my view.
