course for understanding the purpose of LOPA and how to
implement the analysis."

Course Description
LOPA is a simplified form of risk assessment. It
assists in compliance with PSM and RMP regulations and with the ANSI/ISA
S84.00.01-2004 / IEC 61511 standards, Functional Safety: Safety
Instrumented Systems for the Process Industry Sector.
LOPA is often used as an extension of process hazard
analysis (PHA). PHA teams use engineering judgment to decide if
additional safeguards are needed to protect against accident scenarios
they identify. This subjective approach can lead to disagreements and
possibly inappropriate measures to reduce risk. A more rational and
objective approach is needed, at least when considering risk remediation
measures for high risk scenarios or those that are expensive to
implement. Layers of Protection Analysis (LOPA) was developed for this
purpose.
LOPA is also used to comply with the S84 / IEC 61511
standards. S84 / IEC 61511 requires the allocation of safety functions
to protection layers, the determination of required Safety Instrumented
Functions (SIFs) and the determination of their Safety Integrity Levels
(SIL). LOPA is one method used for this purpose. The required SIL of a
SIF is derived by taking into account the required risk reduction to be
provided by that function. S84 / IEC 61511 notes that this is best
accomplished as part of a process hazards and risk analysis (i.e. a PHA)
to benefit from possible synergies and the information developed.
LOPA is used to evaluate scenario risk and compare it
with risk tolerance criteria to decide if existing safeguards are
adequate, and if additional safeguards are needed. Without risk
tolerance criteria, there is a tendency to keep adding safeguards in the
belief the more the safer. This can be a false assumption. Eventually
safeguards will be added that are unnecessary and may add complexity
that can result in new unidentified hazard scenarios. LOPA helps focus
limited resources on the most critical safeguards.
This course describes each step in performing LOPA
and provides experience in its use. A detailed manual is provided for
use as a reference after you have completed the course. Also provided
are Microsoft Excel and PHAWorks® templates for conducting
LOPA studies.
Objective
Learn how to perform a LOPA study to evaluate the
effectiveness of process safeguards. Understand how to use LOPA, Risk
Graph and Risk Matrix methods to select SILs for SIFs.
Target Audience
Process safety personnel, PHA analysts, control systems
engineers, project engineers and others who need to apply or understand
LOPA, Risk Graphs or Risk Matrices.
Prerequisite
An understanding of PHA and PSM and a technical
background are desirable. If you are learning LOPA to comply with S84 /
IEC 61511 attendance at Primatech’s S84 / IEC 61511 course or equivalent
is recommended.
