Cleanroom ceiling tiles to be caulked?

Our cleanroom installer put on clips to 'hold down' the ceiling tiles. The tiles still 'lift' during cleaning. Is the use of clips acceptable?  I thought 797 stated that the tiles needed to be caulked.

You are correct. The tiles needs to be caulked into place so they don't lift up where water could pool while cleaning the ceiling. You need to get this corrected and can cite the chapter. State boards of pharmacy typically find this deficiency and can fine you.

What if the tile has a gasket between the frame and the tile surface?

The gasket could get wet and become a source of contamination after you repeatedly clean the ceiling. Your certifier or hospital facilities folks can put a bead of caulk to cover the gasket.

Eric,

Does this have to be a special type of caulking?

Nope, white silicone caulk will work.

The contractor now has concerns of off gases from silicon and suggests latex caulk.  Does silicon vs. latex matter?

Off gassing of silicone materials is a problem in microelectronics facilities because of interaction with the silicon wafers.  It is not a problem in health care settings.  We have been using it in pharmaceutical facilities since the 70’s.
