In today's video,
we are taking a look at three different types
of fire extinguishers,
how they put out three different types of fire, and why.
[Music]
Guys, we are up here at the Dome today with three different types
of fire extinguishers
because we want to take a look at just what's inside them,
and what kind of tires they can put out.
So to start out with, we need some fire.
Yay, fire!
So first, let's talk about the different types
of fire extinguishers you can normally find for your house.
This is the most
common fire extinguisher you're normally going to find.
This is your ABC fire extinguisher.
Now, A, B and C stand for three different types of fires.
So any type of fire that starts with wood,
paper, trash,
that's a solid fire and that's a Class A.
A Class B fire is actually going to be liquids.
So if you have a gasoline fire,
or an oil fire, something like that,
you would use this with the type B.
You also have the type C, which is an electrical fire.
Now, while these can be used on electronics,
it's not typically the one that you want to use
if you want to save your electronics,
because this will actually produce a residue.
This is another type of fire extinguisher
that's slightly newer in the market.
This is specifically made for kitchen grease fires.
As far as I'm aware,
this is the only UL-approved kitchen grease
fire fire extinguisher.
The first ingredient
in this fire extinguisher is actually sodium bicarbonate,
which is just baking soda.
Now, this is going to put out any sort
of grease fire supposedly.
We're going to test that.
But again, it's going to ruin your food.
This is a third fire extinguisher.
A lot of times you can find these in office settings.
Now, I've never actually used a Tundra fire extinguisher before.
Supposedly, this is an aerosol powered foam spray.
Now, I've never used it.
I'm not even sure what the ingredients are.
I searched and I could not find out online
what Tundra uses in their fire extinguishers,
so we want to take a look at it.
[Music]
That's probably enough.
Note, oil has a flash point of 619 degrees Fahrenheit,
and the fire point of 662 degrees Fahrenheit.
So that's what we're trying to get this to.
Now, we also have some handheld flares today.
Now, technically, none
of our fire extinguishers are made to put out chemical fires,
but I want to see if they can.
These aren't even road flares.
These are Marine flares.
Never used one this before.
We stepped away for maybe 30 seconds,
and our oil is on fire.
That was fast.
Grease fires in the kitchen are extremely dangerous,
because a lot of times people will panic,
they will try and pick up the pot,
and throw it outside.
But you could splash it.
You could spread the fire everywhere or burn yourself.
Another problem with a grease fires is
that people will try and throw water on them.
Now, water is not going to do anything.
It just splashes.
It's just gonna make it worse.
So that's why you use a dry chemical fire extinguisher,
or a CO2 fire extinguisher.
Either of those will work.
I'm going to try one of ours now.
[Music]
That's a lot of fire.
That's why you don't throw water on a grease fire.
That's not putting it out.
What it's doing is
it's actually splashing the oil and spreading it around.
That one burned itself out because again,
we're not using too much oil.
It's time for round two.
[Music]
So last time,
it took us about two and a half minutes with our oil on top
of our forge to hit that flash point and auto-ignition.
All right, 47 seconds.
It's bubbling.
No smoke yet though.
Five minutes.
There we go.
5 minutes, 21 seconds.
[Music]
So now, we're gonna use our fire extinguisher
that's specifically made for fires of these type.
We're going to try and catch some of our baking soda
and the other ingredients in one of the bowls to look at the bit.
Now, these cans, a lot of people think
that they spray for quite a long time.
They actually have about 8 to 10 seconds of spray time.
So you need to move quick.
Aim for the base of your fire
from about five to six feet away.
Make sure that you put the whole thing out.
Usually, you want to make sure that you're aiming all of it
into the container before you back way.
But like I said,
we're gonna let a lot of this burn off,
and then I'll try and capture some as well.
[Music]
Well, that is very useful.
This is a good example of why CO2 fire extinguishers
are sometimes nice.
Yes, that put out our fire very very quickly.
But if that was dinner,
now it's covered in baking soda,
and so is your entire kitchen.
So here's what you're going to find
if you ever discharged a kitchen fire extinguisher.
So it's not that foam and it's not water
like you might see in movies, it's a dry chemical.
Now, this is a bit of an irritant.
So I actually held my breath when I was over there,
got out of the dust cloud very quick,
because well, it's not going to be too hurtful for you.
It can cause irritation to your eyes and lungs.
You don't want to breathe it in.
[Music]
I do have quite a bit of water with me,
and water does put out solid fires.
But I want to test
our fire extinguisher that's specifically made for it,
our ABC fire extinguisher.
Now, the main ingredient in this one,
like I said before is monoammonium phosphate.
Again, I'm going to spray the fire,
and then I'm going to try and capture some of this so we
can look at it afterwards too.
So for this one,
you're going to stand six feet back.
So it's a little bit farther back
than you need to be with your kitchen fire.
You aim at the base of the fire, never at the top of the flames.
[Music]
That was so fast.
Now, this you absolutely do not want to breathe in.
Spray and then get away.
We have our two different types
of dry powder fire extinguisher substances here.
You can already see the difference.
So this one,
you can see the mono ammonium phosphate already has
that strange yellowish tinge.
This one, baking soda.
So now, I want to go and put this through a few other tests.
This stuff is not supposed to be able to put out a gas fire.
I still want to put some in our forge just to see what it does.
[Music]
So first, I'm just going to try sprinkling
some of this in there.
And again, main ingredient is baking soda.
Oh.
Well, that was awesome.
It actually did dampen the flames for a little bit.
[Music]
Wow, that is a much cooler reaction than I was expecting.
I'm just wondering if it's the quantity,
or if this is a small enough contained fire
that it's easy enough
for the ingredients to just snuff it out.
This again would be your normal kitchen fire extinguisher
that's used for grease fires.
Let's try our ABC fire extinguisher.
[Music]
Well, that's awesome.
This is actually changing the color of the flames.
I don't know why, but that's awesome.
So we've already seen
that tossing in a little bit of our fire extinguishing powder
will put out our gas flames for just a couple of seconds.
I'm actually going to try and pour it into a crucible,
and super heat it just to see what it does.
[Music]
Not expecting any huge reactions here.
Because if this were to melt or burn or anything else,
it wouldn't be really useful for a fire extinguisher.
So it's been a few minutes.
Our Crucible is red-hot,
and nothing has happened to our ABC fire extinguishing powder.
So we're going to turn this one off.
Kind of what we expected.
But that's pretty cool.
So, for our last test,
we have got our Tundra fire extinguisher.
Like I said before,
I know that this is an aerosol can,
and I'm pretty sure
that this is going to be a foam spray,
but I'm not positive.
We're going to put this to the test up
against a marine flare.
Now, these are technically chemical fires.
None of the extinguishers
that we have used today are meant to put out chemical fires.
Let's see if they can.
[Music]
Now, this is something that's kind of interesting to note.
While there is a huge size difference,
this fire extinguisher only has a lasting spray
of about 8 to 10 seconds,
whereas the Tundra has about 32 seconds of spray time.
So while it does have a longer lasting spray,
you actually have to be even closer to the fire.
So that's a huge downside to one of these.
The other ones, you can be five-six feet away.
This one have to be about three feet from the fire
to actually put it out.
Thankfully, our marine flare is a very contained fire.
So I'm safe enough
to get that close and see if this is gonna work.
[Music]
Huh?
[Music]
Still going.
All right, I would have been very disappointed in this flare
if it had a gone out because it's a marine flare.
Let's try again though.
[Music]
Oh, this is interesting.
It's not really a foam.
It's basically a water.
[Music]
It's definitely a liquid,
and it has definitely put out our flare.
Liquid foam fire extinguishers versus Marine flare,
fire extinguisher wins.
So these are the fire extinguishers that we use today
because they are the most common ones
that you're going to find around your house,
around your workspaces,
but there are actually five types of fire extinguishers.
These are just the ones that were going to be easiest
for us to test,
and kind of show you what they're going to do,
and the ones
that are going to be most readily available to you.
So, your fire extinguishers.
Are they going to put out the fires they're supposed to?
Absolutely.
Turns out that they can put out a few other things too.
Guys, that's not all.
