Maintaining an MOC
System
1.Monitor effectiveness
2. Audit
3. Demonstrate commitment
Effectiveness of MOC System
Key Performance Indicators
1. The number of MOCs performed each month.
2. The monthly percentage of work requests that are
classified as a change.
3. The percentage of emergency MOCs.
4. The average backlog of MOCs.
5. The average calendar time from MOC origination
to MOC authorization.
Effectiveness of MOC System
Auditing
1. Documentation completed
2. Training conducted
3. Procedures reviewed for updating
4. Pre-Startup Safety Reviews
Management of Change
Pre-Startup Safety Reviews
Pre-Startup Safety
Review
The term pre-startup safety review
(PSSR) means a final check prior
to initiating the use of process
equipment.
PSSR
It is applying a systematic method to
confirm that the startup team and
process equipment are prepared for
startup.
Definitions
Trigger Event
Any change being made to an existing process,
or
any new facility being added to an existing process
or facility,
or
any other activity a facility designates as needing a
pre-startup safety review.
Non-change
Trigger Event
When Should a PSSR be
Performed
1. Capital project approved
2. Changes to Operating Facilities occur
3. Temporary Changes (Flixborough)
4. Restart of an idled process
Best Practices – PSSR
1. Regularly evaluating industry process
safety related incident reports and how
PSSR was potentially involved in the
situation.
Best Practices - PSSR
2. Using electronic databases for
capturing past PSSR
documentation.
Best Practices - PSSR
3. Performing PSSRs on
selected critical maintenance
activities.
Best Practices - PSSR
4. Involving many different
workers in the PSSR
process.
Best Practices - PSSR
5. Selecting a PSSR team leader
who is somewhat removed from
the specific project involving
the change.
Best Practices - PSSR
6. Showing open management
support for the importance of
PSSR.
Compiling and Using a
PSSR Checklist
Compiling and Using a
PSSR Checklist
The role of the PSSR program is
to provide a second layer of
protection around the
management of change element.
Compiling and Using a
PSSR Checklist
Depending upon the specific
processes, materials, intermediates,
and products involved, the PSSR
checklist questions should be
customized to match the facility.
