How much water might you need for an initial knockdown?
This question stems from the Hmmm... thread about a department running out of water.
Assume that a non-hydranted home is about 2,200 sq ft and 50-60 percent involved upon arrival...
I realize there are a ton of variables to factor in, but how much water do you reasonably think you will have to have on scene for a somewhat proficient FD to get a knock on this fire?
My FD brings a 1000 gal and 1800 gal engine for first alarm as well as an 1800 gal and 3000 gal tanker on that alarm. We start with 7,600 gallons of water before we need the first M/A tanker to arrive.
I'm looking for your experiences, opinions and typical response information to compare with FDs in my area.
