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.

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.

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.
