This is the fire we were talking about. It is clear were the fire is. With a eng and one crew to start the search. I would go above. This is were the victuims would be in the most danger. By searching and closing the door to the room above the garage will aid in containing the fire and buy time for a line to be stretched to the top of the stairs. Note any victuims on the way to the door in the kichten would be found by the eng. Just a different piont of view
1) the door between the garage and the house is open. in this case, if you open the door of the house to go inside, you will increase the convection current at the garage entry, produce a chimney effect and the house will burst in flame, and victime will die.
2) the door between the garade and house is closed. So you can open the door of the house.
But, from the outside you can't see.
So what's the tactical way? Put the two nozzles in front of the garage door, set then at max flow rate, fog pattern at 45° and open. After 5 second max, the fire will be out and you will be able to do what you want.
Don't focus on victim because if you focuse only on them, you often loose crucial element and, in fact , disminish the possibility to save them.
As a flashover instructor and studying structural firefighting for more than 10 years, here my view:
- Using a team to search the fire to tell an other team where is it. Bad. In many cases, the US way is to break windows so you disturb the neutral smoke plane and the thermal balance. In this case you need to search for the fire. Avoid breaking windows, enter with a hose line, cool the gaz and observe: you will see a little smoke on the floor, coming from outside and going to the seat of the fire. If you don't see that, flow gently water on the ground, and watch.
- Searching above the fire. Bad. Just take a candle, put your hand on the side then on the top. Wouah!! Hot! Heat goes up by 65 to 70% (convection) as radiation is of only 30 to 35%. So the fire will go up, not down. You want to go up and let the fire on the ground floor. OK. You are in front of the bedroom. Child are inside. You open the door and see the window is opened. What have you done? Creating a chimney effect between the seat of the fire and the window at first floor. In less than 10 seconds, the bedroom is filled with CO gas, smoke and heat. The child die and 5 seconds after, the flames travel from the seat of the fire to the first floor, killing you. You must learn : NIOSH report on Keokuk accident (december 1999)
If you carefully study fire dynamic and accidents, you will have only one option:
- We save visible victime and only them.
- If we don't see victime, we find the fire as it's easy to locate. If we know how to use a nozzle, we can kill it quickly
Or course, on the way to the fire, if we see a victim, we take her out.
And even if you have 4, 6 or 10 guys, don't try to save if you don't see victims! Let's see: a field with corn, and the machine starting to cut the corn. Your young child in the field, in danger. What will you do? Search or go the machine to stop it? Stop if, of couse! Now, you are with 10 friends in the same situation. What will you do? One going to stop the machine and other to search? Be logical: the best chance to save your child is to go, ALL, to stop the machine. How can you imagine it can be different with a fire?
