[underwater exhalation]

00:00:12.000 --> 00:00:18.666
Whenever you put a regulator back in your
mouth underwater you need to clear it before
you can breathe from it again.

00:00:18.666 --> 00:00:22.099
This is perhaps the simplest and most
dangerous of all the skills you will have to

00:00:23.000 --> 00:00:27.966
The most important rule in scuba diving is: never
hold your breath.

00:00:27.966 --> 00:00:32.432
If you hold your breath while you ascend, the gas will expand and can seriously injure or kill you.

00:00:32.433 --> 00:00:37.000
This is why any time a regulator comes out of
your mouth you must blow a steady stream of

00:00:37.533 --> 00:00:40.566
This has to be a habit and needs to be
performed from muscle memory.

00:00:41.000 --> 00:00:44.132
It has to happen without thinking in order for you
to be a safe diver.

00:00:44.133 --> 00:00:46.466
Never hold your breath when you're scuba

00:00:48.000 --> 00:00:52.000
In this video we are going to demonstrate the
two methods for clearing a second stage.

00:00:52.000 --> 00:00:54.066
The first method is the blast method

00:00:54.066 --> 00:00:57.000
and the second method is the purge method.

00:00:57.000 --> 00:00:59.933
Remember: any time a regulator is out of your

00:00:59.933 --> 00:001:01.199
you must blow a steady stream of bubbles.

00:01:03.400 --> 00:01:09.633
This is the blast method. Take the regulator out,
point it mouthpiece down so that it doesn't free

00:01:09.633 --> 00:01:11.733
...steady stream of bubbles...

00:01:11.733 --> 00:01:16.233
To clear the second stage, you simply cough
forcefully through it.

00:01:16.233 --> 00:01:19.666
The purge method, when you take the regulator

00:01:19.666 --> 00:01:21.132
... make sure you blow a steady stream of

00:01:21.133 --> 00:01:26.666
when you put the regulator back in, put your
tongue in the hole of the mouthpiece

00:01:26.666 --> 00:01:29.532
before you push the purge button.

00:01:29.533 --> 00:01:32.966
When you push the purge button,it clears the
second stage.

00:01:33.000 --> 00:01:38.500
When you take a regulator out, if you point it
mouthpiece up, it will free flow.

00:01:38.500 --> 00:01:42.899
And you can go through about 1500 PSI per

00:01:42.900 --> 00:01:46.066
So make sure any time a regulator is out, you
point it mouthpiece down.

00:01:46.066 --> 00:01:51.632
Remember: the most important rule of scuba
diving is never hold your breath.
