Fire Extinguishers

Probably a dumb question but who carries a fire extinguisher in their 4x4 and what type do you recommend for diesel vehicles.

Dry powder extinguishers, identified red with white stripe are universal for a range of fires. These contain sodium bicarbonate under pressure which acts to cool and extinguish the flames. CO2 is given off when it is heated which also slows burning.
Also a couple of fire blankets could be handy.

Think about size of extinguisher too. I've heard that a 1kg can be used up very quickly. I had a 1kg but then bought a 2kg.
Also, I've been advised to carry a garden sprayer (mine is 5l) with water in it for underbody spinifex fires. I also carry a hook to clear out any debris that may collect underbody near the hot bits. Other advantage of the sprayer is to leave it in the sun and you have hot water for a "shower".

As Detectist has eluded to the 1kg ones are bordering on useless and may leave you short in a crisis, for this reason bigger is better, oh and one thing i was told is to make sure you give them a bit of a shake rattle and roll now and then because the powder can settle/cake in the bottom and may let you down.
Good tip on the garden sprayer.

Dry Powder as others have said.

1 x 1 kilo in the back of the 4wd, & 2 more x 2 kilo's in the boat!

I ALSO carry 200 liters of fresh water in 2 x stainless tanks.. that have 12V deckwash pump wired in from a switch on the dash, and plumed to snaplocks on the roo bar out front, and rear bumper as well. I carry a coiled 1/2 inch hose...and nozzle with snap fitting behind the seat - that's long enough to reach all the way back to the boat trailer tires.

My biggest fear I guess is that I get a flat on the tandem boat trailer & don't notice it soon enough to stop before it gets hot enough to self combust.

I have seen it happen to guys boat on his trailer once on the dual carriage way down to Bunbury... simple flat tire - BUT by the time we stopped him the tire was alight and although a passing motorist with an extinguisher stopped - we did get the fire out initially, but the latent heat in the rubber once the dry powder was gone - it re-ignited coz we had no water to cool the tire down. The tire set the fiberglass boat alight. After that all we could do was uncouple his vehicle to save that!

So that gave me the idea to carry fresh water (drinking/survival/washdown etc) to be able to put out a tire fire with water, before it sets the boat alight.... or to be able to put out someone else tire fire (truck) before it sets the load light (using the front roo bar mounted fitting).

I also plumbed my boat trailer with hose and sprayers, so I can plug it into the rear bumper snaplock, hit the deck wash when I pull the trailer out of the salt water after launching and park it in the car park to go fishing - it gets the salt water off, before it drys, to help slow rust. I do the same when i recover the boat onto the trailer after fishing - give it and the under side of the boat a fresh water wash down, while heading back home.

The last thing I did was have a diversion tap where I have a hose plumbed to in front of all the radiators out front... and on REALLY hot days... when towing and the auto trans temps start to creep up above 80C on steep hills etc, I can hit the dash switch while traveling, and spray water mist thru the radiators to work like a coolgadie safe and help cool the:-
water radiator,
oil radiator,
trans fluid radiator,
Steering pump fluid cooler,
Air intercooler,
Air Conditioner evaporator.
Aux Trans fluid cooler.

It actually makes a LOT of difference in a bad situation... about 10 degrees C drop noticeable on the Temp gauge, trans temp gauge and EGT Pyro gauge plus the air con air gets noticeably cooler. I just do it for 5 mins here or there on big hills when I am not happy with how all the temps are climbing....

So - for e.g. towing into Exmouth, uphill over Cape Range, on a 44C day into a 50 knot headwind - it was a life saver!.

But you have the penalty of 200 kilos of water aboard. On a F250, (2500kilo payload) an extra 200 kilos isn't going to make a lot of difference on top of the 250 liters diesel and 160 LPG already aboard.

So 3 extinguishers and 200 liters pressurized water & a delivery hose.

I like having excess fresh water! A quick wash down after a swim at the beach, rinse off dive gear and fishing gear etc. You can never have too much water.

Was actually wondering if I could squeeze a desalination plant in the back there as well ... for making fresh water camping at the beach and out of salt lakes out in the gold fields in a sticky situation even...

People say I over prepare!

Your Mileage May Vary.

All good advise, one thing I will mention tho, dont put the thing in the cab. I had a mate that was unfortunate enough to have a rollover he would have wallked away with just a few scratches but the extinguisher come out of the mounting bracket and got lodged (the handle) in him just below the collor bone and knocked him unconcious. Thankfully near by mine site paramedics were able to tidy him up enought to get him to hospital. He was in a bad way from it all. Probly goes for anything in the cab.
