The purpose of FRAS is to guarantee optimal alignment of the strong focusing magnets and associated components near the experimental interaction points, while at the same time limiting the radiation dose to which surveyors in the LHC tunnel are subjected. A failure in the FRAS control system, or an operator mistake, could provoke a non desired displacement of a component that could lead to damage of neighbouring equipment. Such an incident would incur a considerable repair cost both in terms of money and time. To mitigate this possibility, an exhaustive risk analysis of FRAS has been performed, with the design of protection layers according to the IEC 61511 standard proposed. This paper presents the different functional safety techniques applied to FRAS, reports on the current project status, and introduces the future activities to complete the safety life cycle. }}, }
