- [00:00:09.382]My name is Jiong and I'm the specialist
- [00:00:11.881]for nanofabrication and the cleanroom facility at NCMN,
- [00:00:15.235]and today I'm going to show you the
- [00:00:19.284]operating and safety procedure inside the cleanroom.
- [00:00:22.468]There is a card reader when you go in to access.
- [00:00:27.401]This is the entrance area of the cleanroom.
- [00:00:30.980]Beyond this door, all drinks and food are not allowed,
- [00:00:37.133]or the [unknown], anything that you can eat and drink
- [00:00:41.048]is not allowed beyond this point.
- [00:00:44.139]In here we have to wear some protecting equipment,
- [00:00:48.971]including from top to bottom.
- [00:00:54.378]The hair net, if you have a beard then you have to
- [00:01:00.109]wear the facial mask, and also the shoe covers.
- [00:01:16.881]This is the entrance access to the cleanroom,
- [00:01:20.611]and this is entrance to the service corridors.
- [00:01:23.816]Users are not allowed to go through these doors,
- [00:01:27.086]this is reserved for the service people,
- [00:01:29.750]and this one is for you to access the cleanroom.
- [00:01:32.771]Behind this door is the registration room.
- [00:01:35.463]There is the computer. You have to log on every time
- [00:01:38.427]when you enter the cleanroom.
- [00:01:43.449]Basically it records who is in and out inside the cleanroom.
- [00:01:47.655]In case anything happens we can track them back
- [00:01:51.453]and in case an emergency happens,
- [00:01:53.876]we will know who is working inside and who is not.
- [00:01:55.925]This area is used for wearing all this
- [00:02:01.144]personal protective equipment, including the hood,
- [00:02:04.291]the cover or gowns, and the booties.
- [00:02:10.325]So I will show you one by one.
- [00:02:14.538]There are two cabinets, one is reserved
- [00:02:17.503]for students and postdocs, and one is reserved for
- [00:02:19.679]faculty and staff.
- [00:02:22.798]You can find your own garment and hoodies
- [00:02:26.851]inside this cabinet.
- [00:02:29.410]For example, this is mine.
- [00:02:33.141]Everybody should write their name on theirs.
- [00:02:36.200]And this is a hoodie, this is the garment.
- [00:02:40.548]Let me show you how it works.
- [00:02:44.071]So the sequence you have to remember
- [00:02:49.323]is always from top to bottom.
- [00:02:51.970]That means you wear the hoodies first,
- [00:02:58.324]and then the garment. Be careful not to
- [00:03:01.572]drag the garment on the ground
- [00:03:03.951]because we always consider the ground
- [00:03:07.499]as the dirtiest part inside the cleanroom
- [00:03:11.089]because eventually the dust will fall down
- [00:03:14.033]in the cleanroom on the ground.
- [00:03:19.589]So you put both your feet through the garment
- [00:03:25.474]and then put yourself inside.
- [00:03:29.015]If you remember, put the bottom edge of the hood
- [00:03:33.707]into the garment and then we zip up.
- [00:03:38.075]So this is what it looks like
- [00:03:40.895]before you walk inside the cleanroom.
- [00:03:42.539]Once you have the garment on
- [00:03:44.689]you are ready to wear the booties.
- [00:03:47.111]The booties are here, they are shared for everyone
- [00:03:51.730]Choose the right size for you.
- [00:03:54.227]There are two medium size, two extra-large size,
- [00:03:58.004]and four large size.
- [00:04:00.234]Tie it in a way that they are crossed at the back
- [00:04:04.105]and tied at the front.
- [00:04:17.314]Now the last one is you have to wear the gloves.
- [00:04:21.155]We have small, medium, large, extra large.
- [00:04:24.877]And always have gloves on
- [00:04:26.386]when you are working inside the cleanroom.
- [00:04:28.283]Before you really walk into the cleanroom,
- [00:04:33.114]this is a tacky mat or sticky mat.
- [00:04:35.458]You have to step on it several times
- [00:04:38.487]to take off the floating dust
- [00:04:41.284]underneath your booties or shoes.
- [00:04:45.160]And now you are ready to go inside the real cleanroom.
