Fire Suppression System

[Dr Goggles]

Here is a PM from one of our forum members "Teamleader", the reason I post it here is that Graham Millard from Gem Fire systems in Moorabin in Melbourne has been a great help to us , always friendly and has gone out of his way to help us when we are "in a hurry" to get something right......He carries all of the "Cold-Fire" products........

Look him up and tell him we sent you..........

here's the message , thanks Teamleader for the kind words......


Hello Doc.
I spoke to you briefly at Lake G the other day but I forgot to mention during our chat and/or did not make time to seek you out to thank you for your help on the Cold Fire contact details. I had to leave Wednesday lunchtime which of course further shortened my time there.
I am now the Western Australian distributor for Cold Fire Australia for which I must thank you for a/ mentioning the product on the DLRA forum and b/ supplying me with contact details.
The distributorship came about purely by accident and I am extremely grateful for your help - even though it just came from an innocent comment.
I believe the products in the range have great potential.
I owe you at least a beer and so if I am unable to meet with you beforehand I want to catch up at speedweek 2010.
Sincerely thank you.
Ian - Team Leader - DLRA #585

But of course if you're over in the west.....give Ian a PM.......

hey all, I'm new at this, but have developed the bug. Each easter I get on the grog with Rob C and come home itching to duild something, but never do... This year I think I'm a gonner , I can't get anything done at work as I'm busy trying to digest all I can off this forum and following links
I'm at work at the moment, and have a Chubb bloke working on the fire suppression of a machine for me. I asked him about parts for a suppression system and he said that it'll cost me! Beer that is! So while he's here I'm gunna hit him up. Only problem is, my rule book is at home and I haven't really ever looked into the requirements, and I don't wanna pay the 10 bucks for another book...
Can anyone jot down a few of the things that I would need, so I can get this fella on the job...

Any help appreciated! Huge.

You can download the ruelbook for nicks from our web site I believe.
My memory is 3 nozzles for engine bay and 3 for driver. Nozzles must be properly engineered (not home made) Engine bay should be able to be triggered independantly of drivers compartment. A switch to kill all electrical power to the vehicle must be triggered when the primary (engine bay) system is activated and the electrics cannot come back on. This takes some thought to get right. The fire system itself is straight foward.

Cool , thanks Chris for the prompt reply!

I had a look at the website and there is now only a link to the scta... But I will join the dlra when I get home from work this week, then I'll have my own hard copy. I have a copy of the old rules at home which will be a good starting point till I get the new rules.

Is there any rule on the capacity of the tank?

Speaking of Cold Fire, I was looking at their website recently and couldn't find anything about complete systems for cars. Do they sell them or do we have to go elsewhere for the hardware and then get it filled with their stuff, which by the way, sounds like it is about as good as it gets. Is there a Brisbane agent that can do fills and/or refills?

Cheers

They also do fire sleeve as well . and other assorted saftey gear.
they are in Sydney.
Dave : they also do refills . but I don't know of anyone in Brisbane refilling COLDFIRE

Thanks Ross, that makes it all very simple. Now if only I hadn't sent the Celica to that great car yard in the sky!

Cheers

We empty our Cold Fire bottles into a black plastic closed drum each year. It saves the corrosive problems . Cold Fire is for all intensive purposes a soap, it coagulates and can block the dip-tubes but the main problem is it dissolves Aluminium oxide so it can eat through the tanks.So, we put it in the plastic container and agitate it a few times during the year then get them re-pressurized before the race each year. That way we KNOW they are in tip top shape.

Still the stuff I'd prefer to be sprayed with in a fire...

And do they use nitrgen to pressurize the bottles Sir Goggs? Thats what chubb use to pressurize the foam stuff in the heavy machinery here on site. The foam stuff is like a very oarsum soap. Not sure what its called, but I'll be looking into it. It sits in the bottles for eons, unless some bonehead hits the botton by mistake

the soap stuff is called AFFF or Aqueous Film Forming Foam.......it works because it is a bi-polar solvent and can dissolve oils in water.....therefore it forms a coating over the fuel as well as all the usual things that water does, cooling and excluding oxygen etc.

If the extinguishers you talk about are stainless steel there will be no problem, with corrosion. My concern was a dip tube was blocked in one of ours , this problem evaded the usual check which is a weigh and repressurize, or just a weigh and visual inspection........

Yeah, they use nitrogen, now some will dispute as to whether the aluminium can corrode in the pure N environment.......we lost three bottles,all pin-holed,one of the extinguishers had an Al dip tube, it had a hole near the top...useless in a pinch ......

And of course on the belly tank you need to look at the flexible tube that joins the siphon tube to the top on the bottle
Not much use when you're upside down and the flexible tube has gone hard or broken, then not leaving the the weighted end of the
the siphon tube in the liquid. which was another thing that had failed in our extinguishers
