	All large scale particle accelerator facilities end up utilising computerised safety systems for the accelerator access control and interlock system including search lockup sequences and other safety functions. Increasingly there has been a strong move toward IEC 61508 based standards in the design of these systems. CLS designed and deployed its first IEC 61508 based system nearly 10 years ago. The challenge has increasingly been to manage the complexity of requirements and ensure that features being added into such systems were truly requirements to achieve safety. Over the past few years CLS has moved to a more structured Hazard Analysis technique that is tightly coupled and traceable through the design and verification of its engineered safety systems. This paper presents the CLS approach and lessons learned.

All large scale particle accelerator facilities end up utilising computerised safety systems for the accelerator access control and interlock system including search lockup sequences and other safety functions. Increasingly there has been a strong move toward IEC 61508 based standards in the design of these systems. CLS designed and deployed its first IEC 61508 based system nearly 10 years ago. The challenge has increasingly been to manage the complexity of requirements and ensure that features being added into such systems were truly requirements to achieve safety. Over the past few years CLS has moved to a more structured Hazard Analysis technique that is tightly coupled and traceable through the design and verification of its engineered safety systems.
