Need Help Cleanroom Signs

Ahh, can you explain what that is ?? Is that a sign you hang on the cleaning closet or a room for surgery ?? What's a cleanroom sign ??

edit: it shows you just joined today, but weren't you a member before ??​

 

todd,
"everyone" may be a smaller group than you think (at least there are two of us)
my experience goes way back, in the data recovery business.

these days i occasionally send a drive out to a vendor in florida, i will ask them for current specs for a class 3 clean room. lets see what i get..

 

Never made a cleanroom sign but I would think you would have to have them run a test for particle contamination so when Kirk gets beamed down he does not get your DNA left on the laminate mixed in with his.

 

If you do a google search for cleanroom signs, it looks like the vast majority out there are screenprinted polystyrene .010" or .015", selling for about $7. Some are vinyl decals to stick on glass or walls.
