Water mist extinguisher

[Ewor]

Was just about to change my old powder extinguishers to AFFF and found this water mist extinguisher which sounds ideal for inside motorhomes/caravans

UltraFire 1 Litre Water Mist Fire Extinguisher

Buy the 1+ litre water mist fire extinguisher from UltraFire for class A, B, C & F fires. Safe on electrical equipment. Low cost delivery.

Any extinguisher experts out there who could recommend/Not recommend?

Water? ...........electricity/burning fat or oil.......... Wouldn’t trust it myself.
Maybe ask them down at your local fire station?

The mist is so fine that's its non conductive to 1000v.
The mist excludes the oxygen, it doesn't put out a fire
They couldn't be sold as electrically safe. otherwise

Yes,but what I don’t understand is what happens when the mist turns to droplets,and the droplets turn to a trickle,and the trickle turns to...........
Or maybe it doesn’t,but I don’t know why.

 

[Ewor]

My understanding is that its de ionised water which does not conduct electricity

Im with Podney on this one..Water mist ...eventually turns to water droplets. Water and electric in any form does not go. Full stop.

UltraFire water mist extinguishers are using de-ionised water, which cannot conduct electricity. They can therefore be used on electrical items with voltage of over 1000V (1m safety distance). Please note that not all manufacturers of water mist extinguishers are using de-ionised water.

Throw a bucket of De ionised water on an electrical circuit and watch what happens! Batteries on fork lift trucks with 70v or more used to explode when water (Deionised) came in contact with the cable work or control panel. Personally....Water free on anything electrical .

We could not at any time use a water based extinguisher on electric trucks

With this extinguisher you aren't throwing a bucket of water at an electrical fire.

In what situation would you be throwing deionised water at a lift truck battery?
How would the thrower know it was deionised? Its not something you would normally leave laying around in a bucket.

Anyone attempting this must already have the Darwin award and shouldn't be working near other people

Omni directional flame arrester !! Excluding the oxygen thereby removing one side of the fire triangle.

I think you may also find that on delicate equipment, it has been realised that sometimes water as an extinguishing agent allows a greater degree of recovery/salvage after a fire than does dry powder or similar extinguishing media (and I do have a little knowledge/experience about the subject)

I agree...But the long and short of it is ....You will spray a water mist De ionised or not. This eventually turns to water droplets. On an electrical circuit...it then loses its de ionised abilities and then will short out eventually. Period.

Sorry pappajohn

Goggle 'can deionised water conduct electricity' and see how many websites agree with you!

I can't find a single website.

Suggestion then.....Get one and aim it at the battery bank on your motorhome or car fuse board. Let me know how it goes.....I look forward to your video of you doing it and its out come.

At a direct fire with no electrical wiring in site...then it will work i have no doubt. Would I want to use it in my motorhome where there are cables etc an most nooks and crannies? No. Personally...I would rather use dry foam or Co2 .

The water may well be deionised but surely once it’s been sprayed about it will collect contamination and will therefore no longer be pure. As Kev and Carolyn said, film the experience . We are all waiting with eager anticipation!

 

[Newfie]

I have one, if you are unlucky to have a fire and if it’s controllable. There would be a lot less mess than powder to clean up also you can stop & start it as required

As soon as die ionised water /Mist comes into contact with the environment it loses its ability it was intended for. Hence plastic bottles only for its storage.

Hoover....Its the future!

I give in..... I would rather believe the experts who make and sell them.
They can't certify to 1000v if its going to kill you.
Even Darwin holders will realise the implications of a corporate manslaughter charge.

It’s discussions like this that make a miserable wet day worth living.

We keep a couple of these board, one one the wall in the kitchen and one under the drivers seat.

Kev

Dry foam ...? Co2 is really meant for enclosures, nooks and crannies are not enclosures therefore the co2 would have to rely just on its cooling properties which condense into water ...(chemical necessity)

If you meant dry powder, please don't operate it inside my motorome living area. Dry powder also works as a flame arrester and an oxygen excluder but makes a hell of a mess and offers very little cooling (except via absorption)

[Spriddler]

So what comes out of firemen's hoses when attending a house or a commercial property blaze,...... or a burning m/h come to that?

[Nanniemate]

Fire extinguishers are there to 'aid escape' and not actually fire fight?The fire service will preserve life and put ehe fire out. Heart breaking as it may be it is better for you and your loved ones to watch it burn from the outside and if the van survives clean it up after.

 

[stevewagner]

No good if cooking oil goes up

I think some people are missing the science involved on how a water mist system works. its always difficult to reprogramme your mind but It's not the water putting out the fire, it's working as an omni directional flame arrester plus an oxygen inhibitor as it turns to steam and also a coolant to turn it into steam. Droplet size has been a massively discussed topic with fire 'circles' for a long time now. Buckets of water, jets of water have large droplets so don't work in the same way.
Fire service equipment and procedures have changed in recognition of the importance of droplet size and its application.
Water mist in fixed installations have been around for some time.
