Throughout the day: HEPI install work on BSC7 scrub cleaning prep on HAM 12 – door removed first ~10:15 – contractor on-site for End-Y work ~4:30 – Grant and Robert out to LVEA to crane mounting on the H1 PSL for the squeezer work. Other: Dani and Richard modified the Card Access control so the readers will allow exiting doors without an exit swipe. The enter swipe is still active. This will reduce alarms in the control room, allow contractors and others to leave and enter without being “locked out”, and not pose any hazards, because the LVEA is “laser safe”.
