Fire Extinguishers

Postby Okibi » Sat May 24, 2008 1:27 pm

Following SMs post about his new extinguisher I thought i'd start a new thread so forum members can offer advice on what to buy and where/how to mount your extinguisher(s).

My car has a Quell CAMS approved 1kg fire extinguisher w/ metal bracket (approx $35 from bunnings).

It's better than my previous extinguisher because it has 2 metal straps to hold it in.

When your buying check that the extinguisher gauge says it's still ok. I went through about 8-10 at my local Repco and Kmart stores and NONE were ok, I then went to bunnings and found they had a HEAPS of these extinguishers all within spec.

I've seen some sup regs that say the extinguisher has to be 900grams or larger. But i've also been in events that say you need at least a 2kg extinguisher or 2 x 1kg extinguishers. So that's why I wouldn't buy anything under 1kg.

www.gmsc.com.au/scrutineering.htm wrote:Issue 151 of the CAMS magazine, Peter Lawrence has this to say about mounting fire extinguishers in cockpits.

"The following recommendations are therefore made (on how to mount a fire extinguisher)

* Use a metal bracket with some form of support to prevent sideways movement,
* Use two straps that go behind the steel bracket and tightly hold the extinguisher,
* Use at least four 3mm bolts (or two x 5mm) with load spreading washers and locknuts, and
* Orientate the extinguisher across the car rather than longitudinally."



What not to do:
  • Buy an extinguisher that's not made for an automotive application.
  • Buy a extinguisher with a plastic bracket
  • Mount your extinguisher with zip ties
  • Mount your extinguisher where it could become a missile if it upclips in an accident or hard braking

There's many on this forum with much more experience than myself, can you please add your comments and advice
If you had access to a car like this, would you take it back right away? Neither would I.

Brown Davis in Boronia Melbourne sells an AS 1841.5 extinguisher for $25. They are 1kg drychem and they turn over about 300-400 per month due to their work with the US military. This means that they do not get time to discharge on the shelf waiting to be sold.
(And you can pickup a roll bar at the same time!)
I got an engineering mate of mine to make a carbon fibre bracket, and it has so far passed scrutineering without a hassle. I will take some pics when I can if anyone is interested.
Cheers

Anyone know how I can turn them into thumbs and not blow out the formatting of the page?

I had a close look at a couple of those brackets at scrutineering yesterday. They're a much better mount than most. The extinguisher is held tighter and there's far less risk of unclipping accidentally.

brackets

Hi manga.... just curious, is mine one of the ones that you are talking about?
I was in the White NA with tan leather interior, #18.
If that is the case, what do you see as different from the standard mount and why is it better?

Wun, its now passed scrutineering 3 times without a problem, so hopefully that means it is ok. I did however bring an alloy bracket the first time I used it just in case it was knocked back!
O.T. hope things are well with your car Wun, have you got it back yet?

Cheers
Chris

Hi Chris, no, I don't think I did yor car, I would've remembered the CF mount.

In any case, the cheaper ones are held with just 2 light clips around the middle - there's nothing else. If you kick the clips they'll often undo. These are seriously dangerous things to have flying around a cabin. Imagine dropping one of them on your head from 3 or 4 floors up and you get the idea.

On the ones you pictured there's a mount top and bottom solid enough to help resist serious forces in an accident. Although there's only one clip it's also heavier and has a much better action which doesn't look like being kicked off easily.

Spotted this one for sale by the Victorian Club, I was wondering if in an accident (1kg or more weight attached), probably no one in the passenger seat, if that slot on the right would pull free from the seat's bolt?

I would have thought a round hole either side would make more sense than those open slots.
