Keeping Maintenance Records
To make sure that the safety objectives are met through the lifetime of the system it is important to keep records of all faults, failures and anomalies as they occur. This requires the maintenance of records by the end-user and the System Integrator. It is highly recommended the following data is included: ? Description of the fault, failure or anomaly ? Details of the equipment involved, together with module types and serial numbers where applicable ? When the fault was experienced and the circumstances leading to why it happened ? Any temporary measures implemented to correct or work around the problem ? Description of the resolution of the problem, remedial action plans and impact analysis You must define the procedure for field returns, and repair and defect handling. The information requirements placed on the end user because of this procedure must be clearly documented and given to the end user. The defect handling procedure must include: ? Method of detecting product related defects and the reporting of these to the original designers ? Methods for detecting systematic failure that could affect other elements of the system or other systems, and links to the satisfactory resolution of the issues ? Procedures for tracking all reported anomalies, their temporary solutions and resultant corrective action where applicable ? The information requirements placed on the end users by this procedure must be clearly documented and given to the end user
Preserving Functional Safety
Design changes will inevitably occur during the system life-cycle; to make sure that the system safety is preserved, such changes must be carefully managed. Procedures defining the measures for updating the plant or system must be specified and documented. These procedures are the responsibility of the end user, but the system integrator must supply sufficient guidance so that the procedures keep the required level of functional safety during and after the changes.
Product Level Module and Firmware Updates
Special consideration must be given to procedures for product level module and firmware updates. Updates to the system must include the modification adaptation for application changes and firmware changes. The procedures must include the need to do an impact analysis of any such changes, and the measures to change the system and its application as an outcome of the adaptation requirements. The other requirements specified here must be applied, as well as the requirements specified for the following items: ? Scope definition ? Hazard and risk analysis ? System Functional and Safety Requirements ? System engineering ? Application programming ? System production ? System integration ? Installation and commissioning The definition of these procedures must include the examination and authorization process to be adopted for system changes.
