The following page has been created to act as an engineering package for new hires within the opto-mechanical group in advanced LIGO. It will also hopefully be a useful reference for existing engineers.

Guide to working at the Observatories[edit]

1. Travel coordination guidelines for installation[edit]
1.1 Virtually all work must have a written work permit and many require a hazard analysis. All hazard analyses must be approved through the safety officer and the lab deputy director (it takes time! -- should be sent to the safety officer, David Nolting, at least 1 week before use)
1.2 Read Guidelines for work at a LIGO Observatory M1100264
1.3 Coordinate date and time of visit with the Install Leader (LHO-Vern Sandberg, LLO-Janeen Romie),
1.4 Identify a designated site liaison from the appropriate LIGO Installation Organization M1000348
1.5 Read the site orientation documents:
-- Read the
-- Consult with Vern Sandberg with any other questions
-- Read the
-- Consult with Janeen Romie, Brian O'Reilly or Joe Giaime with any other questions
1.6 Every visitor must attend the 8:30AM MWF meeting at LHO or the 8:20 daily meeting at LLO. They are held in the respective site's control room.
1.7 All work must be reported each day in the alog:
