Abstract

The Advanced Technology Solar Telescope (ATST) is a four-meter class instrument being built to perform diffractionlimited observations of the sun. This paper describes how ATST has dealt with system safety and in particular hazard analysis during the design and development (D&D) phase. For ATST the development of a system safety plan and the oversight of the hazard analysis fell, appropriately, to systems engineering. We have adopted the methodology described in MIL-STD-882E, "Standard Practice for System Safety." While these methods were developed for use by the U.S. Department of Defense, they are readily applicable to the safety needs of telescope projects. We describe the details of our process, how it was implemented by the ATST design team, and some useful lessons learned. We conclude with a discussion of our safety related plans during the construction phase of ATST and beyond.
