Well an initial comment is that I have a friend that is a fire scene
investigator and we have discussed this sort of thing before. She has
seen the aftermath of people that don't know when to give up trying to
fight a fire with the extinguishers and other items they have and end up
as statistics (dead). IIRC from her professional point of view best to
get out and let the professionals sort the fire if an initial attempt
doesn't squash to fire quickly in it infancy.

I'm sure they'll blame the US for supplying all the black market fire
extinguishers, just like they blame the US for their gun problems...

Yea, the initial attempt that won't be possible with a fire extinguisher
ban. It will be fun watching London burn to the ground live on CNN...

This is why you put all the fire extinguishers deliberately closer
to the exit door than the appliance or tool it is to be used on - that
way you have the exit path at your back, and at that time you can
better decide between fight or flight.

Two or more people available: one calls the FD or 911 and then works
on evacuation. The other grabs a hose or extinguisher, and then
surveys the scene again and thinks about fighting back.

One person - grab the phone, dial 911, put it down with the receiver
aimed toward where you'll be fighting from. Give them five seconds
and then start yelling what the problem is, and the address, and that
you're trying to put it out and you'll pick up the phone in a few
seconds...

There is a logic to calling the FD first and waiting for a response
before going back to trying to fight it yourself - but then the fire
has had two minutes or more to get ahead of you. And it might well be
too far gone to handle yourself, write off the house.

And, on the other hand I have put out two fires, using an
extinguisher, that could have burned down my house or workshop.


And I had the muffler guy laugh and make snide remarks at me when he
lit the cutting torch, and I grabbed his garden hose 'just in case'.

That is, till he lit the firewall sound insulation on fire. The
silence spoke volumes, because he didn't say a single word after I
walked over and put it right back out...

But then again, I recently bought a bicycle and on both the front and
rear forks was an arrow shaped decal point at the axal and stating
"failure to tighten this nut not may result in loss of the wheel", so

Oh, that one's courtesy of the liability lawyers. The same reason
they print on the back of sunshields "Remove from windshield before
driving vehicle." There are people who think there's a nice million-
dollar settlement in it because 'they didn't say not to.'

Yes, but can she tell you how many fire scenes she didn't have to go to
at all, because the fire was put out long before the authorities needed
to be called?

They ban real knives and fire extinguishers, but not mothers-in-law.

Hmm.

I think it depends on the rock type. Coal dust will blow easily.
Graphite dust will as well. Basically it has to have a carbon content
high enough to allow it to oxidize. Or be an oxidizing compound in
itself. However even though they won't burn rapidly they can still melt.
Think lava...

Meanwhile, last I looked anyway, regulations required a fire
extinguisher every 25 feet in a slate mine in Wales. I've never seen
slate ignited, but it must be nasty!
Slate : Metamorphosed shale. ie. clay just how hot would it
have to be to be ignited? Wonder what is flamable in a
slate mine?
...lew...
Also Dust...

Almost any dust is explosive when the mixture is right.
But the original was about a fire extinguisher every 25 ft
and I don't see how those would be of any benefit for a
dust explosion.
...lew...(lets remember the original post in the thread)



Im not sure that rock dust IS flammable.

Anyone?

Gunner


I think it depends on the rock type. Coal dust will blow easily.
Graphite dust will as well. Basically it has to have a carbon content
high enough to allow it to oxidize. Or be an oxidizing compound in
itself. However even though they won't burn rapidly they can still melt.
Think lava...


So granite or shale (not oil shale) dust wont burn?

The rot set in a few years ago in the UK when all the extinguishers in
issue were changed from very easy to identify colours to a uniform
"fire extinguisher" red.

Previously we had the following very logical colour code.

Red - Water
Blue - Dry Powder
Beige - Foam
Black - CO2
Green - Halon

Also at the time of the colour change all extinguishers were moved
from sensible locations adjacent to the hazard to a location adjacent
to an exit.

In addition the guidelines were rewritten on evacuation and
firefighting procedures meaning that fire extinguishers should only be
used to assist your escape.

So, in the case of a fire, you have to do the following

1) Shout FIRE

2) Go to your nearest exit, briefly look at all the pretty red
extinguishers and decide from the printed label which one is
suitable.....and because you are not supposed to return to a fire, you
leave the building

3) On the way out sound the alarm

4) Assemble at the designated point and let the fire destroy the
building.

P.S. I'm not joking about the above.

While mines existed in the past, slate in Wales is now very rarely
mined underground, it is usually quarried. Some mines have also had
their tops removed to permit open cast working.

I can only assume that the extinguishers are there because of a need
to suppress fire at source for preservation of breathing air, 25 feet
seems VERY excessive though - it's certainly never been a
requirement in UK coal mines (what little remain) although a fire in a
coal mine is a seriously *bad thing*

I believe you: before I retired, my employer came up with a similar plan
which varied only in that specific individuals were to insure that all
others had exited the workplace.

This was in spite of the fact that the workplace was quite well equipped
to permit the extinguishment of any type of fire that might be
encountered.

Now be fair. We have a plan for a bucket brigade for the case when a fire
breaks out at work. From the diesel tanks!

If it will oxidize, it will burn. That is, if the compound will
give up an electron and recombine to form a different molecule - it
will "burn". You can do this with regular steel bar stock and enough
pure oxygen. But if you divide it fine enough (grind it) the 'dust'
will combine with atmospheric o2. You're just reversing the smelting
process :-)
Now, rock dust is another matter. Some of it may oxidize in a
vigorous manner (burn or "explode") but I don't know enough geological
chemistry to say.
OTOH, in a shale mine you might ("might") have a problem with
methane gas. Which is not good.

Oh, it's easier than that.
Just apply a flame to a bit of steel wool.
Or gold leaf.
