S84  / IEC 61511 Standard on Safety Instrumented Systems (SIS) and the Development of a Safety Requirements Specification (SRS)

Course Description

Safety instrumented systems (SISs) play a key role in process control to achieve safety and productivity. Their purpose is to take a process to a safe state when predetermined set points are exceeded. SISs are also called emergency shutdown systems, safety shutdown systems, and safety interlock systems.

Several standards have been enacted to address the reliability of SISs. ANSI/ISA S84.00.01-2004, Functional Safety: Safety Instrumented Systems for the Process Industry Sector, first issued in 1996, has now been harmonized with IEC 61511 issued in 2003. In March 2000, OSHA issued a letter, reaffirmed in November, 2005, stating that the S84 standard is considered "good engineering practice" for safety instrumented system design. This effectively makes the S84 standard part of process safety management (PSM) since paragraph (d)(3)(ii) of the OSHA PSM standard specifies: "The employer shall document that equipment complies with recognized and generally accepted good engineering practices".

S84 / IEC 61511 identifies three Safety Integrity Levels (SILs) for the process industries and specifies site performance requirements for each level. Different levels of risk require different levels of safety system performance.

SILs are often determined using information taken from a process hazard analysis (PHA). PHAs as currently performed often do not include all the information needed for SIL determination. The course provides guidelines to facilitate performing PHA for SIL determination and attendees participate in a workshop session to practice using these guidelines.

This course describes all the requirements of the standard. However, a key requirement is the development of a Safety Requirements Specification (SRS). The course explains how to prepare the SRS and attendees develop a SRS in a workshop session.

A detailed manual is provided for use as a reference after you have completed the course.

Objective

This course describes the requirements of these standards. It explains how to decide on appropriate safety integrity levels and teaches you how to evaluate the existing level of protection in your facility. The role of process hazard analysis (PHA) in SIS evaluation is explained. You will perform a layers of protection analysis in a workshop session to assess the risk from a facility using an approach that moves beyond the purely qualitative analysis of a PHA.

Target Audience

Process safety personnel, instrumentation engineers and others who need to apply the S84 / IEC 61511 standard.

Prerequisite

Experience in process safety is helpful.
