DEFINING PROCESS SAFETY
Let’s Split the Terms
info@ifluids.com
www.ifluids.com
PROCESS
PROCESS:
Any activity or combination of activities concerning the use,
storage, manufacturing, handling and movement of
hazardous substances
info@ifluids.com
www.ifluids.com
SAFETY:
Safety is a Quality of Mind – Being and Feeling
Safe
You can feel Safe due to the
SAFETY
• Systems present
• Technology
• Equipment
• Procedures
• Practices
• People
• Experience, etc.,
info@ifluids.com
www.ifluids.com
WHAT IS PROCESS SAFETY?
A blend of Engineering, Management and
Operational Skills focused on preventing
catastrophic incidents particularly explosions,
fires and toxic releases associated with the use
of chemicals and petroleum products
info@ifluids.com
www.ifluids.com
How is PSM different from
Occupational Safety ?
Process Safety:
Pro-active and centered on the safety integrity of the process towards
accident prevention.
Occupational safety:
Focuses more on injuries to workers – i.e., very much a Reactive focus.

Several catastrophic accidents have occurred, resulting in
loss of life and significant property damage.
Union Carbide: Bhopal, India (Dec 1984)
Chernobyl: Ukraine (April 1986)
Piper Alpha: North Sea (July 1988)

PSM Rules -1992
After series of serious accidents ( like Bhopal gas Tragedy & Piper alpha,
North Sea ) that occurred in 1980’s , OSHA developed Process Safety
Management rules in 1992.
These rules made mandatory for Chemicals handling , storing /processing
chemicals above a Threshold quantity.

Keys for Success
36
info@ifluids.com
www.ifluids.com
• Managers and supervisors set the tone
for your safety culture. The leadership
team MUST “talk the talk” AND “walk the
walk.”
Management
Commitment
• The leadership team allocates resources
– people, time, and invests money in their
teammates, demonstrating their
commitment to safety. Leaders know that
safety adds value to the company.
• Fastest way to destroy a safety culture’s
credibility is through a leadership team’s
disregard for the safety rules.
37
info@ifluids.com
www.ifluids.com
• Build TRUST! Do what you say
Communication
• Ensure timely and appropriate responses to
identified hazards.
• Proper safety techniques and procedures training
• Celebrate the successes along the way!

Continuous Improvement –
Are we better than we were yesterday?
➢ Continuously review your own policies and
procedures, especially after an incident.
➢ Re-train your teammates when
deficiencies have been corrected.

❑One of the most important elements
❑IDENTIFY and ANALYSE significance of POTENTIAL HAZARDS
associated
❑Analyses potential CAUSES and CONSEQUENCES of Process
Incidents
❑Reduces consequences of accidental releases of hazardous chemicals.
❑Focuses on equipment, instrumentation, utilities, human actions (routine
and non-routine), and external factors that might affect the process.
info@ifluids.com
www.ifluids.com
❑ There are multiple PHA methodologies/ techniques out there, viz.
➢Checklists
➢What-if Analysis
➢Hazard Identification (HAZID)
➢Hazard and Operability Study (HAZOP)
➢Failure Mode and Effects Analysis (FMEA)
➢Event Tree Analysis

❑Need to be:
•
•
•
•

9.Management of
Change
info@ifluids.com
www.ifluids.com
▪ Definition of “Change”
✓Any Change/Modification in Machine, Material and Method.
info@ifluids.com
www.ifluids.com
MANAGEMENT OF CHANGE (MOC)
➢Change includes all modifications to equipment, procedures,
raw materials, and processing conditions other than
"replacement in kind”.
➢Changes in process technology can result from changes in:
➢production rates,
➢new equipment, new product development,
➢change in catalysts, and
➢changes in operating conditions to improve yield or
quality.
info@ifluids.com
www.ifluids.com
➢Equipment changes can be in:
✓materials of construction,
✓equipment specifications,
✓alarms and interlocks.
➢Establish means to detect both technical and mechanical changes.
➢Where the impact of the change is minor and well understood, a check list
reviewed by an authorized person, with proper communication to others
who are affected, may suffice.
➢For a more complex or significant design change, however, a hazard
evaluation procedure with approvals by operations, maintenance, and
safety departments may be appropriate. -> HAZOP/ HAZID based on Risk
Ranking
info@ifluids.com
www.ifluids.com
Changes in documents, as below, should be noted so that
these revisions can be made permanent when the drawings
and procedure manuals are updated.
Copies of process changes must be kept in an accessible
location to ensure that design changes are available to
operating personnel as well as to PHA team members when
a PHA is being prepared or being updated.
info@ifluids.com
www.ifluids.com
Change of Personnel
(OISD-GDN-178)
❑ Introduction of new personnel may introduce new hazards.
❑ Each employee shall be trained in an overview of the process and in
the operating procedures BEFORE field deployment
❑ Training shall emphasize on specific safety and health hazards,
emergency operations including shutdown, safe work practices
applicable to employees' job task.
❑ The employer shall ensure that each employee involved in operating
a process has received and understood the required training. COMPETENCY
❑ A record shall be prepared containing the identity of the employee,
date of training and the means used to verify that the employee
understood the training.

10. Pre-Start up Safety Review
info@ifluids.com
www.ifluids.com
Pre - Startup Safety Review
▪ PSSR facilitates the safe transfer of projects from the construction stage to
operation stage.
▪ A PSSR must be performed for new facilities and for modified facilities.
▪ PSSR must confirm that :
• Construction and equipments are in accordance with design specifications;
• Safety, operating, maintenance, and emergency procedures/system are in
place and are adequate.
info@ifluids.com
www.ifluids.com
➢Follow-up PHA Reviews/ HAZOP Recommendations
➢Field Rounds – Technical HSE Site Reviews
➢Document Reviews
➢Specific Equipment/ Loop – detailed Checklists
➢Punch Points
➢Cat. A = “HOLD”. Complete before commissioning
➢Cat. B = complete parallel to commissioning;
➢Cat. C = complete after commissioning as per agreed upon
action plan

info@ifluids.com
www.ifluids.com
11. Mechanical Integrity
info@ifluids.com
www.ifluids.com
❑ Is a “Breakdown” Philosophy used?
❑ Requires that a Mechanical Integrity Program be in place to ensure the continued integrity of process
equipment.
❑ Elements of a mechanical integrity program include:
➢ Identifying And Categorizing Equipment And Instrumentation,
➢ Inspections And Tests And Their Frequency;
➢ Maintenance Procedures;
➢ Training Of Maintenance Personnel;
➢ Criteria For Acceptable Test Results;
➢ Documentation Of Test And Inspection Results; And
➢ Documentation Of Manufacturer Recommendations For Equipment And Instrumentation.
