USP 797 FAQ: Can I put a computer/printer/keyboard in the cleanroom?

One of the more common questions I get asked is if a (computer, printer, keyboard, any machine with a fan, pencil, floor mat, etc.) can be put in the ISO Class 7 cleanroom or Class 8 ante-room. Usually when asked the assumption is that the answer will be no. According to the USP’s FAQ website page, this is a myth:

112. What physical objects are allowed to be in the clean room, such as floor mats, printers, pens, markers, shelving, etc.?

There is no prohibition to particular objects, devices, and materials in clean rooms or buffer areas. The presence of such items must be verified according to the Environmental Testing and Surface Sampling standards to maintain the air and surface quality required for these compounding areas.

In other words, as long as you are still passing your particle count and surface sampling tests, you can have whatever you need in the cleanroom or buffer area. A few suggestions to make sure that those objects don’t cause you to fall out of compliance: Pay attention to your air return vents and place anything that is going to give off extra particles like a computer or printer next to them so that those particles are immediately sucked out of the room. Also, keep in mind that you will have to clean and disinfect anything you take into the cleanroom… keyboards and floor mats aren’t “banned” but cleaning them could be a pain  (remember that you should be cleaning under the floor mats too). Keyboard covers may make the job easier.
