The labao cameras (just like the tiptilt camera) are safe during pop changes as long as you do not open any labao shutters. You will notice increased counts on the labao cameras (just like in the tiptilt camera) whenever ND=0 alignment laser is going through the system, but this is not harmful as long as the labao shutters are closed. While observing none of the labao shutters need to be or should be opened. As usual, dim the laser after you are done with the pop change to protect any camera in the lab from ghost reflections and scattered laser light. | The labao cameras (just like the tiptilt camera) are safe during pop changes as long as you do not open any labao shutters.
