Inspected the foam sealant around the 7 cable ports (two between the Enclosure and the Anti-room, and five between the laser room and the LVEA) in the PSL laser room. A couple of the ports had almost no foam sealant installed, and in a few other ports the foam sealant had fallen out.

  Installed, replaced, and renewed the foam sealant around all 7 cable ports in the PSL enclosure. The laser room is now much better sealed. This should increase positive pressure inside the laser room by a small amount.
