Tyvek Suit Use

NTS, 4/24/2015

[Note: Tyvek suits are to be worn when dealing with potential As flake situations, e.g. Full Open chambers, or large components that have been in a chamber.]

[Note: All Tyvek suit use requires a respirator!]

[Note: Glovebagging doesn't need Tyvek suits due to the glovebag containing any flakes.]

Putting Suit on

1. Put on your cleanroom suit like normal

2. Enter the lab with your respirator (on or in hand) and obtain a Tyvek suit that will fit you (for reference 5'5"-5'9": Medium)

   1. Go into the bat cave, take your respirator off or put down.

3. Put on two pairs of clean (not UC) gloves (total for now), with the outer pair over the cleanroom suit cuff

4. Tape the outer of the two to your cleanroom suit, making a good seal, using white ~1" wide tape from the tape drawer

   1. It will likely be imperfect due to your wrist not filling the glove and suit and being a circle

   2. Do not get the first glove (under the second) taped at all; just the second one

5. Put on the Tyvek suit, paying special attention to the feet and not ripping the arm/shoulder part. Leave the hood down.

6. Put on another pair of gloves (that might be tight but should be relatively kind of comfortable enough), with the gloves over the Tyvek suit cuff

7. Tape these gloves with caution tape to the Tyvek suit cuff, making a good seal

8. Put on your respirator and raise the Tyvek suit hood (respirator under hood)

9. Put on final outer layer gloves (layer 4) that you do NOT tape

   1. These are you outer disposable gloves, and are meant to be changed easily, and should be changed often/as needed.

[Note: You now have four layers of gloves, the respirator, and the Tyvek suit on over the cleanroom suit]

Use

1. Your Tyvek suit is meant to protect you and your cleanroom suit from As flakes.

2. The outer layer of gloves is meant to get dirty and protect your third layer mostly; change as often as needed

3. If you were touching something dirty or maybe dirty, before touching ANYTHING else that is not dirty, take off your outer gloves and replace them.

   1. This includes: solvent bottles, packs of wipes, doorknobs, control rack buttons, chamber shutter knobs, the airphone, etc.

Taking Suit Off

1. Take off outer layer (layer 4) of gloves and dispose of in As trash (doiat)

2. Untape layer 3 gloves and doait

3. Carefully remove Tyvek suit and doiat.

   1. Pay special attention to getting your cleanroom booties out of the suit.

   2. Once your arms are out, you can reach into suit as needed to aid with removal

   3. You will have the normal cleanroom suit on and only make contact with the inside of the Tyvek suit

4. Untape layer 2 gloves and doait

5. We are now in a normal respirator state

6. Leave cleanroom and remove respirator, cleanroom suit as normal; leave cleanroom as normal
