- Hey, it's me, Destin.
Welcome back to Smarter Every Day.
Earlier this year, I had an amazing opportunity to board
a U.S. Navy nuclear submarine on an ice flow in the Arctic.
This is the next video in a Smarter Every Day
deep dive series into submarines and how they work.
So far, we've learned about the command structure
and how torpedo tubes work,
and there's a lot more videos to come.
Given the fact that while on board this submarine,
we're literally under several feet of ice,
it's very important to me to understand how to handle
situations that could jeopardize the boat.
We have to be able to fix these problems
from within the submarine,
because a little problem could grow
into a big problem in a hurry.
So the word of the day for this video is:
- Casualty.
- Casualty.
- Casualty. What is a casualty?
- Casualty is what we call
any kind of problem, I guess you can say.
So a fire, a flooding, those are casualties.
So we are...
One of the biggest things that we train to,
it's like I talked about,
submarine's a very unforgiving environment,
is to very rapidly, aggressively attack any kind of casualty
in order to save the ship and save each other.
So that's what we spend a majority of our time training to.
- This is Matt.
Chief Charleton is gonna be the primary person
to walk us through the different ways of responding
to fire or flooding on the boat.
- Okay, we just got in,
and we have to get trained on what to do
in the event there's a fire.
- You sink it, no ability to surface,
no fresh air, right?
So we have EABs, Emergency Air Breathing system.
So you have these manifolds all over the boat.
What you do is you turn this right,
it's just a little plug that'll fall out.
If you look on the deck here,
if you have a rectangular non-skid pattern,
that means it's directly overhead.
If you have one of these triangular shaped,
then it's kind of on the bulkhead
and you have to just look for it.
- Got it.
- So the first step you wanna do
is save yourself.
Plug the hose in,
so you have an air supply.
(air hisses)
And you kinda gotta shove it up in there.
Some of them are a little stickier than others are.
And then you always want to clip this
on your belt on the left side,
because in a smoke-filled compartment,
you're not gonna be able to see anything,
so you have to kind of feel around.
So if somebody is always putting it on their left side,
then you know where it's gonna be.
- Okay.
- Somebody taps you, you can plug into somebody else.
- Oh, okay, you share.
- Yep, and then what you do
is you put your chin in the bottom here
and pull the straps up over your face,
and then you tighten bottom two straps tight,
then you tighten the top.
And the you pull the flash hood over like that,
and so this is to protect you from heat damage.
Obviously, you wanna roll your sleeves down if it's hot.
You wanna get out of the affected space as soon as possible.
But this is going to let you breathe
in a smoke-filled compartment.
- Yes, sir. - Okay.
- Can I try it?
- Yep.
- So first things first, I'm gonna put this on my belt.
- Left side.
- Left side, left side.
Just plug it straight in, or is-
- You got to shove it way up in there, yep.
(air hisses) You'll hear it a click.
There you go. - Oh, nice.
All right, then you pull your mask on.
Let me get my...
- Done?
- All right, so now if you want to check
and make sure you've got a good seal,
what you'll do is you'll take a breath in,
twist that to the clockwise,
and then you're gonna wanna hold it,
'cause it's gonna pop out.
And then make sure you've a good face seal.
If you get any air in there,
then you're not gonna get a good seal,
and you can get some-
(air hisses)
(indistinct)
So now plug it back in.
(air hisses)
Good to go.
- Cool, that's easy.
And the right thing to do is for me to yell "air"
before I do that, right?
- You can, that's just a submarine thing.
You wanna let people know that
"Hey, I'm gonna cause a noise."
It's not really normal to have air anywhere.
So if we hear that, it could perk somebody's ears up
and say, "Hey, what's going on?"
So we just kinda do that to let everybody know
what's going on.
- Got you.
- So in fire, I would not worry about that.
- Nobody cares in fire, so I say--
- In a fire, if you're going around saying "air,"
we'll all gonna look at you like you're crazy.
- Air!
So I did that wrong?
- Yeah.
- (laughing) I'm supposed to hold it when I do it.
- (indistinct)
- Yeah, okay, yeah.
The things you learn on the first day on a submarine.
So where would this be located?
- Crew's mess is like a centralized area for everyone
that's off, we're just gonna hang out here anyway.
- Yeah.
- And if a fire was to happen right now right now,
because they're out here, they would just grab this.
They're not gonna run into the rack, grab an EAB,
and then run to the unaffected compartment.
- So what does the call sound like in the event of a fire?
If there's a-
- There would be an announcement on the 1MC,
which is the general speaker,
followed by a general alarm, it's just...
It bongs for about 26 seconds,
and then it'll turn off and then they'll announce fire.
And it will do a big long announcement for where it is,
with the class is, how to route the hoses, things like that.
- We're going to come back and see how they actually
a fight a fire together.
But first, let's head down and see what they do
if water starts to flood the boat.
Okay, so we're in the torpedo room, which is awesome.
That's a torpedo by my foot, you know, normal stuff.
But my understanding is this is the room
that's most likely to flood, is that correct?
- Yes, sir.
- Now why is that?
- So we have the torpedo tubes that are directly to sea.
So we have one here, or two here.
- Yeah.
- And then two on the port side of the ship, as well.
- Okay, got it.
So the idea is if you get a leak there or something,
it's gonna come in,
water's gonna be everywhere here,
and you gotta get it out fast.
- Absolutely.
- And so this is a pump, you're telling me?
- Yes sir, so that's a portable submersible pump,
