"One question: if the fire has not extended into the house, do we want to open the interior doors to the fire compartment? Can we treat the attached house as an attached exposure (Strip mall with fire walls). Put PPV in place to…"
is your question; during overhaul, what CO levels require your crews to be on air? The answer to that should be, ALWAYS. The stuff that is killing you after a fire, is not CO. It's nano particles, hydrogen cyanide,…"
"For the record, I'm not staking out a position here. The question was asking was; if the best thing that can happen as a result from an effective vertical vent is that the fire is going to take off (smoke and low O2 lift and 21% O2 moves…"
"I would agree with Mr. Brush. I would have stated a lot of the same things, but not as eloquently. Both ventilation techniques are tools and a tool is only as good as the user's training on it. I have difficulty in using…"
"Excellent information added to this post Brian. You are right on track, as I closely follow all your work on ventilation. Taking the the time to train and understand the true science, is much more of a difficult path to follow, than blanket…"
While we are getting some great information from these studies there is still a lot ahead. I have heard the information regarding the vertical tests from Steve and I have also heard what has yet to be tested. Information is great and improved…"
Please could the folks that have education, experience and thoughts, take a minute and weigh in on this.UL and Kerber are putting together the data from the vertical ventilation test houses and are also putting together a possible test plan for PPA. What I got from it, and I could be over simplifying, was that you will not get any improvement to the interior environment from having crews on roofs. We have the work that Chief Garcia and Chief Kauffmann on Horizontal Pressure Ventilation which…See More
"This sounds like rumor and propaganda to me.
Who told you this and what proof did they offer? This test was run by the FDNY and you can disregard the 1st Strike results, but the 15/16 is close enough to what you were asking…"
Larry, I finally completed the Skills Competency Workbook Project. It is cheaper to buy the published version than it is to have it printed. It will be available the first part of October at www.createspace.com/3690367
It just hit me after sending you my last post. Was it you that requested some info from us on our Vinidcator nozzle? I am not in the office right now but I could have sworn we sent out some info to your department and we were going to set up a time for us to come out.
unfortunatly Larry there is not. Bobby Halton and I have tried for years to get such information from the manufactures and all they could ever provide was therory and NFPA formulas. Snap-tit was the only one that provided measured fact based numbers and those were from the tests we did with them 15 years ago.
If you have a local fire equipment dealer they should surly be able to loan you a flow meter for testing but you will also need at least 2 inline pressure gagues.
Determine the gpm you want to test at, set your pressures so that the flow meter reflects that target gpm (calibrate flowmeter first), then you can look at the pressure gagues and have a fact based FL number.
We have found as much as 110psi of loss in a preconnect flowing 200gpm.
I have also found good 1 3'4" hose that had less FL than 2" even while flowing 50 more gpm.
If there is anything I can do to help just let me know.
Im hoping that question wont get me in trouble, I dont think it can but who knows. Im amazed how many depts are enforcing this bylaw recently and how little evidence I have found on people trying to fight it. I hope I didnt come off as a jerk not wanting peoples opinions on this topic, I was just afraid that if people voiced their opinions, what I was trying to find out would be lost in the battle. If I find any thing out I will let you know.
That's what I am afraid of with our face book page. I have been trying to get the chief to give me a yeah or neah and now the deputy is saying talk to the chief asap about it and it's been almost two months since I emailed the chief on it. It is nothing defamatory or anything it is a positive promoting the vol fd and for recruitment. Whatever he says will be the ruling, he's the boss.
I travel a lot so if you see anything we need removed simply call me at 201 406 8278 my personal cell and I will take it down. Also I could really use more guys like you and Brent to tell the new guys to use their full names and no sceeen names. I eliminated Jon Olivers last post. Call me anytime, Bobby
