S84 / IEC 61511 Standard on Safety Instrumented Systems (SIS) and
the Development of a Safety Requirements Specification (SRS)
|
"If you are not practicing S84 be
afraid, be very afraid."
- Brian Powell, Praxair |
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 performance
requirements for each level. Different levels of risk require different
levels of safety system performance.
This course teaches the important concepts and terms
needed to understand the S84 / IEC 61511 standard and it describes its
requirements and its relationship to PSM. The detailed requirements for
a Process Hazard and Risk Assessment (PHRA) and the allocation of safety
functions to protection layers are discussed. A key requirement of S84 /
IEC 61511 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. Also provided is a Microsoft Word
template for preparing the SRS.
Objective
Understand the overall requirements of the S84 / IEC
61511 standard for SIS. Understand the requirements for a PHRA and the
allocation of safety functions and how they relate to PHA. Be able to
prepare a SRS for each SIS.
Target Audience
Process safety personnel, control and instrumentation
engineers, project engineers and others who need to apply the S84 / IEC
61511 standard.
Prerequisite
Experience in process safety is helpful.
