This document discusses process safety management. It defines process safety as preventing incidents that could release hazardous materials or energy. It notes that process safety needs to be considered separately from occupational safety. The document then discusses several key components of process safety management, including process hazard analysis, operating procedures, management of change, employee participation, incident investigation, emergency planning and response, and compliance audits. It provides details on what each component involves, such as developing written procedures for ongoing integrity of process equipment under mechanical integrity. Standards and guidelines from various organizations are also compared.
2. ProcessSafetyManagement
Introduction - What is ProcessSafety?
Process Safety is a disciplined framework for managing the integrity of
operating systems and processes handling hazardous substances by
applying good design principles, engineering, and operatingpractices.
Processsafety is everyone’s responsibility
Continuousimprovement
Away of thinking andacting
It is a culture.
3. ProcessSafetyManagement
It deals with the prevention and control of incidents that have the
potential to release hazardous materials or energy. Such incidents can
cause toxic effects, fire, or explosion and could ultimately result in
serious injuries, property damage, lost production, and environmental
impact.
Process safety needs to be considered seperately from occupational
safety.
4. ProcessSafetyManagement
ProcessSafety is avery common and usedtopic in the chemical industry.
According to CCPS,an incident is reported asaprocesssafety incident ifit
meets all four criteria (process involvement, above minimum reporting
threshold, location and acuterelease).
Although power plant industry doesn’t handlehazardous chemicals as
much aschemical, petrochemical or refining industry, it hasthe same
equipments which canbe the source of similar accidentssuchas:
Boilers, Tanks, Cooling towers, Reactors, etc.

14. ProcessSafety Information
To be assesedin processhazard analysis and management of change,following
information should beconsiderd:
• Processand instrumentation diagrams (P&I).
• Block or simplified diagrams of the process, flowdiagrams.
• Diagramsof electrical installations.
• Alist of criticalcomponents.
• Massand energy balances.
• Acceptable upper and lower limits for variables and any deviationsfrom
variables.
• Asafety data sheet of the substances
• Theclassification of electrical areas.
• Designand layout relief and ventilation systems.
• Specifications for pipes andequipment.
• Adescription of the interlock and shutdownsystems.

provided at least every three years, or more often
if necessary, to each employee involved in
operating a process to ensure that the employee
understands and adheres to the current operating
procedures of theprocess.
Training
Ininital training: PSM requires that each employee
presently involved in operating a process or a newly
assigned process must be trained in an overview of
the processand in its operating procedures.

22. Contractors
When selecting a contractor, obtain and evaluate information regarding the
contract employer’s safety performance and programs. Inform contract
employers of the known potential fire, explosion, or toxic release hazards related
to the contractor’s work and theprocess
Explain to contract employers the applicable
provisions of the emergency action plan
Develop and implement safe work practices
to control the presence, entrance, and exit of contract employers
and contract employees in covered processareas
Evaluate periodically the performance of contract employers in fulfilling their
obligations; and maintain a contract employee injury and illness log related to the
contractor’s work in the processareas.

25. Pre-Start Up Safety Review
Prior to start-up or implementation of a significant change,followings should be
checked:
Any documents which may be affected by the changemust have been modified
(procedures, instructions, etc.).
Thestaff affected by the changemust have been adequately informed/trained.
Themodified procedures must have been made available to the staffaffected.
In the event of changesto the conditions of the activity, the relevant authorisations
must have been issued and the staff affectedinformed.
There must be compliance with applicable laws and all the relevant authorisations
and licenses must have been obtained.
That, where appropriate, findings from completed hazard assessmentsmust be taken
into consideration.
That all safety systems must be fully operational

31. ComplianceAudits
To be certain process safety management is effective,
employers must certify that they have evaluated
compliance with the provisions of PSM at least every three
years.
This will verify that the procedures and practices
developed under the standard are adequate and are being
followed.
The compliance audit must be conducted by at least one
person knowledgeable in the process and a report of the
findings of the audit must be developed and documented
noting deficiencies that havebeencorrected.
The two most recent compliance audit reports must be
kept on file.
