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.
