Mehtap VURAL
Industrial Safety Projects Coordinator
 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 operating practices.
Process Safety Management
Introduction - What is Process Safety?
Process safety is everyone’s responsibility
Continuous improvement
A way of thinking and acting
It is a culture
 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.
Process Safety Management
Introduction - What is Process Safety?
Process Safety is a very common and used topic in the chemical industry.
According to CCPS, an incident is reported as a process safety incident if it
meets all four criteria (process involvement, above minimum reporting
threshold, location and acute release).
Although power plant industry doesn’t handle hazardous chemicals as
much as chemical, petrochemical or refining industry, it has the same
equipments which can be the source of similar accidents such as:

To be assesed in process hazard analysis and management of change, following
information should be considerd:
• Process and instrumentation diagrams (P&I).
• Block or simplified diagrams of the process, flow diagrams.
• Diagrams of electrical installations.
• A list of critical components.
• Mass and energy balances.
• Acceptable upper and lower limits for variables and any deviations from
variables.
• A safety data sheet of the substances
• The classification of electrical areas.
• Design and layout relief and ventilation systems.
• Specifications for pipes and equipment.
• A description of the interlock and shutdown systems.

Process Safety Information
Hazard identification and evaluation is contemplated at
every stage of the plant’s operations, from the initial
project to the day it is decommissioned. This includes
identifying the potential dangers associated with
 Operating conditions
 Start-ups, stops, maintenance and special
situations
 Previous incidents
 Process Hazards
Components of Process Safety
Hazard Analysis
 Potential accidents and their consequences caused
by;
 Failure of monitoring, controls, alarms,
interlocks, ESD
 Human factors
 External events
 Failure of safety management system
In every 5 years a process hazard analysis should be
developed.
Components of Process Safety
Hazard Analysis
The operating instructions must cover all possible operative stages:
 Start-up
 All phases of normal operations, including testing, maintenance and
inspection
 Detection of and response to, departures from normal operating conditions.
 Temporary or special operations
 Operation under maintenance conditions.
 Normal shutdown
 Emergency operations including shutdown.
 Decommissioning
Components of Process Safety
Operating Procedures
Most of the accidents occur during non-routine operations.
Operating limits:
 Consequences of deviation, and
 Steps required to correct or avoid deviation.
Safety and health considerations:
 Properties of, and hazards presented by, the chemicals used in the process;
 Precautions necessary to prevent exposure, including engineering controls,
administrative controls, and personal protective equipment;
 Control measures to be taken if physical contact or airborne exposure occurs;
 Quality control for raw materials and control of hazardous chemical inventory
levels; and
 Any special or unique hazards.
 Safety systems (e.g., interlocks, detection or suppression systems) and their
functions.
Components of Process Safety
Operating Procedures
Consult with employees and their representatives on the development and
conduct of hazard assessments and the development of chemical accident
prevention plans and provide access to these and other records required under
the standard.
 Develop a written participation plan
 Consult with employees on PHA and PSM development
 Provide to employees access to PSM information
Components of Process Safety
Employee Participation
Ensure contractors and contract employees are
provided with appropriate information and
training.
 Identify the training needs of employees
 Identify the training perods
 Training plans
 Evaluation of eEffectiveness of training
Components of Process Safety
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 process and in its operating
procedures.
Refesher Training: Refresher training must be
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 the process.
Components of Process Safety
Training
 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 the process
 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 process areas
 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 process areas
Components of Process Safety
Contractors
 Written procedures to maintain ongoing integrity of process equipment.
 Establish a quality assurance program to ensure that initial process-related
equipment, maintenance materials, and spare parts are fabricated and
installed consistent with design specifications

Prior to start-up or implementation of a significant change, followings should be
checked:
 Any documents which may be affected by the change must have been modified
(procedures, instructions, etc.).
 The staff affected by the change must have been adequately informed/trained.
 The modified procedures must have been made available to the staff affected.
 In the event of changes to the conditions of the activity, the relevant authorisations
must have been issued and the staff affected informed.
 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 assessments must be taken
into consideration.
 That all safety systems must be fully operational
Components of Process Safety
