- Dang!
- Oh my God.
That is insane.
- [Nolan] What the heck, dude?
- We bought the Jaws of Life.
You know, those big hydraulic scissors,
that firefighters use to cut open cars
and save people's lives?
- Well, it turns out you don't have to be a firefighter to
get your hands on some.
All you need is your dad's credit card
and an eBay account.
- But what really makes these,
the number one tool for saving lives?
- [Justin] Well, today,
we're gonna compare the Jaws of Life,
to other methods of cutting into a car
and figure out why firefighters rely
on this heavy, specialized piece of equipment.
- Welcome to Donut.
- [Hawk] Thank you to Keeps for sponsoring today's video.
Hair loss has been eradicated on earth.
But in a universe where two out of three guys
experience some form of male pattern baldness
by the time they're 35.
We're on a mission to tackle universal hair loss.
(cannon explosion)
- [Hairless Cat Pirate] Surrender, captain Maine,
you're missing to tackle universal hair loss is over.
Fire the cannons.
- The Starship follicle surrenders to nobody.
Especially to hairless cat pirates.
Doc Mop hit him with the Keeps.
- Hit him with Keeps?
That's crazier than a water bug on crack dials back.
- I don't know what that means Hawk, but here we go.
(baseball triumphant music)
(explosion)
- It worked.
- Of course it did.
Keeps offers clinically proven research
about treatments to stop hair loss
and is shipped right to your door.
- Great work team.
That could have been a real catastrophe.

- [Justin] Inside this big box right here
is our brand new Jaws of Life that we bought online.
We're gonna crack it open
and see what the heck we just bought.
- Dang!
(Jeremiah roars)
- Oh my God.
No wonder firemen are so buff.
- Really.
- [Nolan] Watch it. Hydraulic fluid on your shirt.
- [James] Oh mother.
- [Nolan] Oh, look at that.
Oh that's the pincher.
- [Justin] These are the real jaws right here,
baby. - [Nolan] Oh.
This is way lighter.
- [Justin] Is it?
- [Nolan] Yeah.
These are coming in the next Doom Eternal DLC.
(all chuckle)
(metallic sounds)
- Roscoe.
- Let's cut some stuff in half.
Save some lives.
Gentlemen.
(James sniffs)
(hip-hop music)
- [Justin] All right.
So let's talk about what we just bought.
There are three main components to the Jaws of Life.
This is the cutter, used to cut hinges, pillars and bolts.
This is the spreader, it's used to separate metal
to get to those hard to access places of the car.
And this is the ram, it's used to push a collapsed dash
off the injured person's legs.
All three of these tools are interchangeable,
depending on the situation.
But obviously,
cutting and spreading metal takes a ton of force.
So how does this tool manage to do it so well?
- [Justin] A generator. - [Nolan] Generator.
- [Zach] Yeah.
We could turbo that.
(all chuckle)
- [Justin] With this little lawnmower engine.
Well kinda.
This engine drives a compressor
that creates pressure in the hydraulic lines.
As the hydraulic fluid moves through the pressure lines
in the head, the tool opens and closes.
It's the same mechanical principle
as most construction equipment.
This handle here is what controls the movement of the tool.
As you can see, it moves very slowly.
This may seem counterproductive in an emergency situation,
when time is of the essence.
But the power and precision is
exactly what makes it the go-to tool for saving lives.
The precision allows us to make the right cut
without potentially injuring the passenger further.
But we don't really have any idea of what we're doing.
- What the heck, dude?
- [Justin] And this thing is potentially super dangerous.
So I headed to the local fire station
to get some tips and tricks on how to use this thing.
- If you cut the pillars, cut high.
So you're above the seatbelt tensioner.
- Cause that can, in rare instances, cause problems.
Set up here.
(upbeat music)
- [Justin] So it turns out these things
have a lot of steps to operate them safely.
You need someone by the generator to hit the kill switch,
if anything goes wrong.
You need someone by the doors
to make sure they don't go flying off when you cut a hinge.
You need someone surveying the whole scene
to watch out for a potential danger.
But most importantly, you need to be sure
not to stand in between the tool and the car
so you don't accidentally get pinned by the jaws.
- You always want to have your body
outside of your working area.
So you'll never have you between the tool.
'Cause if you start turning,
and then they will start bending and pulling,
you don't want to get pinched.
- Yeah. A lot of times are tough to reposition.
'Cause wherever the tool's going, the tool's going.
You're not gonna win. - Yeah you.
- [Justin] So before we jump straight into saving lives.
I wanted to try it out on something that's easy to cut.
So we grabbed a door
and got to cutting and spreading on that.
Let's cut through some doors.
(upbeat music)
- Fire it up!
- All right.
(upbeat music continues)
(James chuckles)
- Give me your arm.
- Hell yeah.
(upbeat music continues)
- [James] Dude, that's so sick.
- Like butter, dude.
(upbeat music continues)
Oh, these are gonna be great to have around the shop.
(Justin laughs)
- Fire me up.
- Spread that door!
(hydraulics sound)
- Safe to say that works.
This thing is cool.
But, honestly it seems pretty inconvenient.
I mean, other cutting tools could do
just as good of a job, right?
- Now this thing is gnarly.
It cuts right through metal
by using 10,000 pounds of pressure
provided by hydraulic fluid.
Today, we're gonna see just how good it is
by comparing it to tools we have laying around the shop.
A sawzall, a cutting wheel, and a cutting torch.
I thought we could start with something
a little bit smaller just to get our bearings.
Let's give it the beans.
Nolan, are you ready?
- Yeah, this is so scientific.
(sawing sounds)
- [James] Whoa! That's art dude.
- [Nolan] Pretty sick. - Dude, that sick.
- And now the cutting wheel.
(sawing sounds)
This is so stupid.
(all laugh)
- All right, so here we've got an oxy acetylene torch.
Like butter!
(upbeat music)
- [Justin] So clearly these are all really good at cutting.
But, are these tools actually dangerous
in the life saving scenario?
- [Nolan] What the heck, dude.
- [Justin] I'm sorry, Nolan.
Imperial get any beans?
Doesn't look like it.
- [Nolan] No, it's sprayed all on me, Justin.
(Justin laughs)
- Let's talk about what makes the Jaws of Life,
such a special tool for saving lives.
First, it's precise.
Making the right cut once is essential,
when a life is at stake.
Which brings us to number two, time.
When in the right hands,
the Jaws of Life can help safely remove a passenger
in under two minutes.
And finally, even though it's heavy, it's pretty portable.
This thing fits on the fire truck and it's easily removable
when it comes time to help in a roadside emergency.
And more modern Jaws of Life are actually battery powered.
Making them even faster and more portable.
But, ultimately, what makes this thing so special
is it doesn't create sparks.
This control system keeps the crash passenger safe
because there's no spark to potentially ignite any gas
that has been spilled by a crushed tank
or a busted fuel line.
(drilling sound)
- Yeah! Celebrate!
(bang)
- [Justin] So we've set up a simulated emergency situation.
Picture this.
Nolan Junior spins out on the highway,
flips his dad's awesome brand new 1996 Buick Regal.
He's trapped inside.
The doors are smashed shut.
And the fuel line busted, gas is spilled everywhere.
Our firefighting team has to cut the B and C pillars
in order to safely remove Nolan Junior and his passengers.
Let's see how these other cutting tools fare,
in a real emergency.
- Don't worry Nolan. I'm coming to save you.
(sawzall drilling)
- [Justin] I think you've killed him.
- I can keep going.
- [Justin] The sawzall was portable and quick.
But it wasn't very precise,
'cause it cut into Nolan Junior's head.
- Oh.
- [Justin] And on top of that.
It shed some sparks,
which could have sent the whole Buick up in flames.
- All right. So obviously the sawzall's
not the correct tool for this job.
Oh yeah.
(angle grinder buzzing)
- [Justin] The grinder was also very portable
but it wasn't particularly fast
and it couldn't make it through the whole pillar.
Obviously it sent sparks everywhere.
- Not very safe for the passenger.
It's not maneuverable enough to navigate the tight spots.
So yeah, not good.
(upbeat jazz music)
- [Justin] The acetylene torch wasn't particularly portable.
And sure, it was quick.
But if the car blows up,
you're essentially toting around
another explosion waiting to happen.
- Okay.
Oh God Nolan!
(water hose)
- [Justin] And well, it also burned
right through Nolan Junior's skull.
So, that's not gonna work.
- [Zach] He's gonna have a little bit of
trouble doing math from here on out.
- Okay, so quick review we saw sparks, fire,
and brain damage and they weren't even that fast.
So let's see with the actual firefighters tool,
the Jaws of Life, and see how fast it actually is and safe.
Get our new passenger out.
Nolan Junior, junior, junior, junior, junior.
(upbeat music)
It's that easy.
Just like that.
We've got the pillar out of the way.
And Nolan Junior, junior, junior,
junior, junior, junior, junior, junior, junior
is safe to pull out.
But there's still one more thing left to do.
All right, Nolan, I'm here with you.
Let's do this. - Let's do this.
Give me my sawzall and my beans.
(gas generator revving)
(upbeat music)
- It looks terrible.
- [Nolan] Yeah, we cut the doors off and the roof off.
All right. Who wants to go for a ride?
- Sure. - Yeah.

And step number one to safety, is being seen.
I don't feel very seen in this shirt covered in beans.
That's why we made this news Donut high-vis T-shirt.

- [Zach] Okay.
Oh God, Nolan.
Oh buddy.
I'm sorry bud.
You're gonna think a little bit different
from here on out, I think.
