TCS Laser keys removed by me
In prep for removing the BSC1 door, I turned to OFF, and then removed the keys to the TCS lasers in the LVEA.
After we were finished putting the door back on yesterday I put the keys back in the TCS power supplies and turned them back on. Beam blocks have been in place on the table for a few weeks mow however so this was just extra caution.
