CAFS Nozzle Selection & Pressure
Looking for help from those of you out there using CAFS.
About 3 months ago we took delivery of a new engine with a CAFS system on it.
Prior to the truck being delivered, I did as much research as possible and chose to purchase Akron Pyrolite Shutoffs with 1 3/8" Blitz Tips on them. Much of this research was from questioning other departments using CAFS as well as reading threads on this site.
After the truck was delivered and we had our training by the vendor, he told us to run the CAFS at approximately 100psi thru the smooth bore nozzle. The problem we are having is that the nozzle and hoseline is WAY too hard to handle and we are concerned about our members being hurt trying to fight the line.
We have since tried to use fog nozzles with the CAFS (the old Turbojets we took off the old engine) with reasonable results - we are still getting a good enough CAFS out of the fog nozzle to have foam that will stick when applied and the nozzle is MUCH easier to control. I know that theoretically that the fog nozzle should be breaking up the CAFS bubbles, however, like I said it is working to a level that would be okay for interior operations.
We are looking to demo the TFT CAFS Force nozzle to see if it works better than either of our other options.
My questions are:
1. What type of nozzle are you using with CAFS for interior ops?
2. What is your normal operating pressure for CAFS with the above nozzle?
3. Have you had any experience with the TFT CAFS Force nozzle ?
Thank you for your help with this.
Look up Nozzle Forward by Aaron Fields. It says it all. Smooth bore H2O!
CAFS will not penetrate fire gases if they are above 1112 degrees. I sorry but structural fires burn hotter than that. So, basically you are steaming (Maytagging it) yourself and anyone who may be a potential victim of that fire. To make an aggressive interior attack with CAFS....I have done it. Only one thing will penetrate those gases. Smooth bore water. CAFS was invented for the forestry and should stay there! To say it prevents water damage...well I have never seen a house that couldn't be dried out that's why you pay those restoration companies to come in. Either way they are coming in CAFS or no CAFS. It has been proven that smooth bore absorbs more heat than Fog and you don't steam yourself. Quit making yourself hot! It doesn't help.
