| Layers of Protection Analysis (LOPA) for Process Safety Management (PSM) | 02-Mar | 06-Mar | AHMAD RAKAB |
Details :
LOPA is used to comply with the IEC 61511 / ISA 84 standards. IEC 61511 / ISA 84
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. IEC 61511 / ISA 84
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 PHA Works® templates
for conducting LOPA studies.
Learn how to perform
a LOPA study to evaluate the effectiveness of process safeguards.
Process safety personnel, PHA analysts, control
systems engineers, project engineers and others who need to apply or understand
LOPA.
