ITMY CO2 stopped lasing at 10:00 local and ITMX CO2 stopped lasing at 10:05 local. Both RTD/IR sens. alarms tripped. Only ITMY recovered itself successfully (still required me going to the rack and hit GATE button to restart the laser) while ITMX interlock ramped down and came right back to the tripped value (what the hell happened here?). I'm not aware of any restarts that could have caused them to trip. Both FLOW ALARMs were okay.
