The use of a SIS as the single and only means of risk reduction should be subject to detailed inspection. The faster, easier way to work with standards. An SIS is composed of a separate and independent combination of sensors, logic solvers, final elements, and support systems that are designed and ba to achieve a specified safety integrity level SIL.

The list should identify each loop, and the loop’s unique identifier. This document sets the standards for safety-related system design of hardware and software.

An SIS may implement one or more safety instrumented functions SIFswhich are designed and implemented to address a specific process hazard or hazardous event. The essential roles of the various personnel assigned responsibility for the SIS should be defined and procedures developed, as necessary, to support the consistent execution of their responsibilities.

Field data are collected through operational and mechanical integrity program activities to assess actual SIS performance. When the required performance is not met, action should be taken to close the gap, ensuring safe and reliable operation.

The reason why the example control systems and functions are representative should be given. Demonstration could be made by inclusion of a sample operating procedure. If the site has control systems that pre-date appropriate standards, or no longer has the original documentation to show the design approach, then the site should review its existing measure against BS IEC to establish any possible shortfalls in the existing systems, and to inform any further action, if necessary.
