Process Safety by Tarek Alwerfally 2024.pdf

This presentation by Tarek Werfally, [email protected], is for Process Safety for Hazardous plants, its related to rules of safety and how workers should be aware of it, all slides are very useful Ensuring the safety of workers and preventing accidents in such environments is paramount. Tarek Werfally’s presentation likely covers a range of critical aspects, including:

Risk Assessment and Management:
Identifying potential hazards specific to the plant, such as toxic chemicals, flammable materials, or high-pressure systems.
Quantifying risks through techniques like Hazard and Operability (HAZOP) studies, Failure Modes and Effects Analysis (FMEA), and Layers of Protection Analysis (LOPA).
Implementing risk reduction measures based on the hierarchy of controls (elimination, substitution, engineering controls, administrative controls, and personal protective equipment).
Safety Culture and Training:
Emphasizing safety as a core value within the organization.
Regular safety training for all employees, contractors, and visitors.
Encouraging reporting of near misses and incidents to learn from them.
Emergency Preparedness:
Developing emergency response plans for various scenarios (fires, chemical releases, explosions).
Conducting drills and exercises to ensure everyone knows their roles during emergencies.
Maintaining communication channels with local emergency services.
Process Design and Equipment Integrity:
Ensuring that process design accounts for safety features (relief valves, emergency shutdown systems, etc.).
Regular inspections and maintenance of equipment to prevent leaks, corrosion, or failures.
Monitoring critical parameters (temperature, pressure, flow) to detect deviations.
Human Factors:
Addressing fatigue, stress, and human error.
Properly designing workspaces and ergonomic considerations.
Encouraging a safety-first mindset among workers.
Remember that safety is a collective effort, and continuous learning and awareness are crucial. While I couldn’t find Tarek Werfally’s specific presentation, exploring resources from organizations like the Center for Chemical Process Safety (CCPS) can provide valuable insights. Stay safe! 🌟 .

2. Process Safety تايلمعلا ةملاس
Process safety is a disciplined framework for
managing the integrity of operating systems and
processes that handle hazardous substances. The
goal of process safety and asset integrity is to
prevent unplanned releases which could result in a
major incident.

4. We respect hazards
•We improve our understanding of process safety hazards
at our location and our roles in controlling them.
•We are vigilant about the potential impacts of
uncontrolled process safety hazards.
•We discuss process safety hazards before starting a task.
•We bring forward process safety hazards to be included
in activity risk assessments.

5. We apply procedures
•We use operating and maintenance procedures, even if we are familiar with the
task.
•We discuss the key steps within a critical procedure before starting it.
•We pause before key steps and check readiness to progress.
•We stop, inform supervision and avoid workarounds if procedures are missing,
unclear, unsafe, or cannot be followed.
•We take time to become familiar with, and practice, emergency procedures.

6. We sustain barriers
•We discuss the purpose of hardware and human barriers at our location.
•We evaluate how our tasks could impact process safety barriers.
•We speak up when barriers don’t feel adequate.
•We perform our roles in maintaining barrier health and alert supervision to
our concerns.
•We use an approval process for operations with degraded barriers.

7. We stay within operating limits
•We discuss and use the approved operating limits for our
location.
•We escalate where we cannot work within operating limits.
•We alert supervision if an alarm response action is unclear or
the time to respond is inadequate.
•We obtain formal approval before changing operating limits.

8. We walk the line
•We use up-to-date documentation that accurately reflect
installed systems and equipment.
•We physically confirm the system is ready for the intended
activity.
•We alert supervision to identified documentation and readiness
issues before operation.
•ةتبثملا تادعملاو ةمظنلأا ةقدب سكعت ةثيدح قئاثو مدختسن نحن.

9. We control ignition sources
•We identify, eliminate, or control the full range of potential ignition
sources during task risk assessments and during job preparation and
execution.
•We minimize and challenge ignition sources even in “non-hazardous”
areas.
•We eliminate ignition sources during breaking containment and start-
up and shutdown operations.

10. We stop if the unexpected occurs
•We discuss the work plan and what signals would
tell us it is proceeding as expected.
•We pause and ask questions when signals and
conditions are not as expected.
•We stop and alert supervision if the activity is not
proceeding as expected.
•تم وه امك ريست اهنأ انربختس يتلا تاراشلإا يه امو لمعلا ةطخ شقاننعقو.

•عقوتم وه امك ريسي لا طاشنلا ناك اذإ فارشلإا هبننو فقون.

11. We watch for weak signals
•We proactively look for indicators or signals that suggest future
problems.
•We speak up about potential issues even if we are not sure they
are important.
•We persistently explore the causes of changing indicators or
unusual situations.

12. How should we use Process Safety
Toolbox talks &
Safety meetings
Can we learn from
incidents that involved a
PS not being followed?
Pre-job planning
•How are the PS
applicable to the
work we are doing
today?
•What do we need to
do to follow the PS?
•What needs to be in
place?
•Is everything in place,
and in good working
condition?
Post-job reviews
•Did we take all the
actions associated
with the PS?
•What went well?
What didn’t go well?
•Is there anything to
note for the next
time we have to this
perform task or
work in this area?
Intervention
•Intervene or stop
the work if a PS is
not being followed
Observations &
walkabouts
•Do you see anyone
performing work
where a PS is
relevant?
•Are they following it?
•Yes? Great, recognise
it!
•No? Intervene!
•If someone brings up
a PS dilemma, thank
them and show them
you will take it
seriously.
Last minute risk
assessment
•Have I done all the
PS actions relevant
before the job?
•Is everything as we
discussed in the pre-
job planning?
•Are there any Line of
Fire hazards or
ignition sources we
didn’t identify?
STOP
