Notes and Changes:

Information was added about dead reckoning the beam position on QPD1 in case the worker cannot see the faint beam.

Laser Safety: Any personnel who will be working on or near the HAM1 Optics Table shall first be authorized by the local Laser Safety Officer, by training and discussion regarding setup and task, and follow the requirements detailed in LIGO-M960001, LIGO Lab Laser Safety Plan, and any site specific laser safety requirements that pertain to the work performed. The wearing of laser safety goggles and any other required personal protection equipment shall be strictly followed, as well as any special safety design/setup that prevents injury or property damages.
