 It's full range of motion, shoulder to shoulder, slowly head rotation, right? You're going to get to see what's going to go on so that you know what to expect when you get in there. Then you're going to ask to do chin rotation, imagine a cow, you're going to be asked to jog in place. If you are not our runners, just kind of, you know, high step it, there you go. Alright, then you're going to be asked to break the seal on your mask. You'll be told when to break the seal and when to put your mask back down. Make sure that when you break the seal on your mask, you stop breathing and you close your eyes. Depending on the length of time, you may have to take a breath. If that happens, that's fine. You may experience some irritation, alright? That's normal. It's expected. If for any reason, you have, sorry, I'll get to that in a second. Once you're told to re-feel your mask, bring it back down, re-secure the pad, make sure you exhale and seal until it sections to your face, alright? Once you enter the chamber, if you notice before or during any of these exercises that you already have a poor seal, all you have to do is raise your hand. Sorry, Garcia will come up to you and he'll determine whether or not you need to exit the chamber. You'll go in through this door and out through the other door, alright? You'll take all commands from Sara and Garcia the whole entire time that you're in the chamber. Are there any questions? Alright, for expectation management for you, a normal chamber is anywhere from three to six tablets through the length of the time. We have one. So if you've survived basic training, this is not going to kill you, alright? I understand some of you have some anxiety about this. The whole purpose of going through the mask experience is to build your confidence in your equipment that your mask is going to save your life should it be necessary. Okay? Strength and first rank only.
