Ventilation Basics

Here's a good example of how to not use ventilation for any of the things we call priorities on the fireground. If we want anyone including us to survive we have to keep a charged, working hoseline in areas where there is fire if we are going to vent. Bringing a dry line that might get charged and then going to work ventilating the whole house would be a no go, it goes under that thing where if we cannot get a line on the fire why are we venting?

Now if we want to open this smoke charged structure we better have the necessary resources on scene to get right to work because as you can see it gets rockin when we open up here!  Even though Mr.Obvious shows his head about the basement fire, we still send a crew right in above the fire, the ventilation indicators give warning that this might not end well. Type of construction comes to mind too as the two windows upstairs that could be opened up are not, instead we commit a crew to a time consuming vertical vent?

So control the fire by controlling the vent, horizontal vents will do alot if weather and other factors like size are adequate. The size up of where venting is necessary is critical and needs to be reported back to the fire attack crew. Bring the right tools to the vent job so you can get it done and either get off the roof or move on to the next job!

Now I'm sure they are doing their best but lets not lose sight of the ventilation basics, good crew assignments and safety.

Ventilation Practices

Common ventilation practices have tried to advance beyond common sense and this is never a good thing, kinda like NFPA adding all the foolish "safety" standards to fire service apparatus.
In the video you see two components of a vertical vent go well and fire attack go poorly which demonstrates my first thought here, why are we not communicating enough information so that ventilation does get done in direct relation to how the fire fight is getting done?

Why do we book ventilation to death and teach young minds to always get the PPV set up quick so we can get the smoke out when there are many other firefighting issues to consider like construction and fuel load for starters?

Underwriters Labs has put together some great information on ventilation that is based on facts instead of "backdraftology". Check it out!!

Good Vent Job

These guys go get it done very well, I did wonder if the blades were dull as I thought man that vent job should already be done. That was maybe because the biggest screw up you see a lot is that firefighters go to the roof and take way too long which greatly compromises their safety, go get this job done and come off the roof.

I put this out there because ventilation is very important to efficient firefighting operations and we cannot forget this. Also if you kinda survey the scene as a firefighter when your coming up on a fire you will generally see the best area to vent, if you watch the smoke in this video you know they made a good choice.

Remember we are doing this for their lives and ours and that gets us back to the station in good shape!
