5. What is SIMOPS?
Simultaneous Operations (SIMOPS) are activities that take place at the same time and meet the following
conditions:
❖ Activities that are located in the same area; and
❖ Activities that could directly or indirectly potentially affect the safe performance of another
activity (e.g. Breaking Containment and Hot Work)
6. Types of SIMOPS
ROUTINE SIMOPS
Simultaneous operations where all the activities involved have been previously identified and the controls
documented and their execution covered by existing, approved written instructions or procedures Eg:
Routine Maintenance activities on site
NON-ROUTINE SIMOPS
Non-routine or ‘occasional’ SIMOPS can occur in the case of maintenance and/or modification works
within the units of an existing facility or in the case of installation (or construction) of a new facility within
the vicinity of an existing operating facility. Eg: Turn Around maintenance activity (Shut down activity)
7. Types of Temporary Defeats
Process Defeats
Any process-related bypass required / enacted by the DCS operator during start-up / shut down (unless
specifically designed for start-up or shut-down or controlled by OEM (Original Equipment Manufacturer)
approved Standard Operating Procedure, during process upset or in the course of handling emergency
conditions
Maintenance Defeats
Any bypass related to enabling the undertaking of corrective or preventive maintenance. The following are
typical means employed as temporary override devices on instrumented functions:
Maintenance Override Switch (MOS) - installed by design for the purpose of testing and maintenance;
Force: An imposed healthy signal within an Instrumented Protective System;
Mechanical (Hardware force) - physical override (examples include wire bridges, pneumatic bypasses,
physical removal of protective device such as a minimum stop); and (IV) Wire jumper.
-----------------------------------------------------------------------------------------------------------------------------------------
Temporary Bypasses / Defeats
Temporary Defeats or bypasses of HSECES are enacted only to allow certain work to proceed without
causing unnecessary process shutdown or interruption or fire alarm. HSECES may only be temporarily
bypassed for the purposes of safe start-up (unless controlled by Standard Operating Procedures), testing,
maintenance or repair. In the case of fire detection sensors, these may also be temporarily bypassed
during hot work etc. where such work may cause false equipment shut-down.
Extended Period Defeats
Extended Period Defeats include temporary defeat which is to remain in place beyond the planned
duration of approval. If extension is required, the respective Approver decides whether a separate
Temporary Defeat Risk Assessment is required or not and provides a separate validity and approval for the
extension.
 Permanent Defeats
HSECES shall only be permanently bypassed as part of engineered changes to operating facilities. Such
permanent implementations should be managed by ADNOC Management of Change process. Refer to
ADNOC Management of Change COP for more details.

8. Types of Isolation and explanation?

don the mask before being overcome
AMBER ZONES IN ZWSC
❖ Riser Platform (RP);
❖ Riser Platform –RP-1

23. Hydrogen Sulphide
Hydrogen sulfide (also known as H2S, sewer gas, swamp gas, stink damp, and sour damp) is a
colorless gas known for its pungent "rotten egg" odor at low concentrations. It is extremely
flammable and highly toxic.
Hydrogen sulfide is used or produced in a number of industries, such as:
❖ Oil and gas refining
❖ Mining
❖ Pulp and paper processing
❖ Rayon manufacturing
Hydrogen sulfide also occurs naturally in sewers, manure pits, well water, oil and gas wells, and
volcanoes. Because it is heavier than air, hydrogen sulfide can collect in low-lying and enclosed
spaces, such as manholes, sewers, and underground telephone vaults. Its presence makes work in
confined spaces potentially very dangerous.
The health effects of hydrogen sulfide depend on how much H2S a worker breathes and for how
long. However, many effects are seen even at low concentrations. Effects range from mild,
headaches or eye irritation, to very serious, unconsciousness and death.
H2S CONCENTRATION IN ZWSC CAN GO UPTO 2300 PPM
24. Conflicting Activities

25. Confined Space Entry
A confined space is a space with limited entry and egress and not suitable for human inhabitants. An
example is the interior of a storage tank, occasionally entered by maintenance workers but not
intended for human occupancy. Hazards in a confined space often include harmful dust or gases,
 asphyxiation, submersion in liquids or free-flowing granular solids (for example, vessel, tanks, pits,
sewage etc.), electrocution, or entrapment.

7. SIMOPS
Simultaneous Operations (SIMOPS) are activities that take place at the same time and meet the
following conditions:
 Activities that are located in the same area; and
 Activities that could affect the safe performance of the another activity (e.g. Breaking
Containment and Hot Work)
 Wherever possible, operations should be managed to avoid situations where simultaneous
operations (SIMOPS) could arise, however at times, it may be necessary to perform
operations simultaneously
8. JOB SAFETY ANALYSIS

15. What is isolation – positive, proved , non-proved

 Energy Isolation is the process of establishing a secure break in the energy supply to ensure
that inadvertent reconnection is not possible. Effective energy isolation ensures that
equipment remains safely isolated for the duration of any work activity and prevents
accidental re-pressuring or re-energizing of equipment before personnel have ceased work
and equipment integrity has been restored.

All isolations shall meet the Baseline & Minimum Isolation Standards. It details the following:
 Positive Isolation (Mechanical Isolation): removal of a spool and fitting of blinds, or fitting of
a spade or spectacle blind
  Proved Isolation: Valve isolation where effectiveness of the isolation can be confirmed via
vent/bleed points
 Non-Proved Isolation: Valve isolation. No provision to confirm effectiveness of valve

16. The Permit to Work (PTW) is an 8-step process

Work Request and Planning: A comprehensive planning process that include Integrated Work
Activity Planning (IWAP) process, providing clear description of work scope details and carrying out
Initial Job Analysis (using Work Categorization Chart) to decide further course of action and PTW
type.
Identify & Approve Controls: A formal process of conducting Job Safety Analysis involving all
relevant personnel basis the initial job analysis for identifying controls necessary to reduce the risk
level to ALARP followed by a final approval by authorized personnel to proceed.
Worksite Controls & Implementation: A critical process for ensuring safe working conditions prior
to work permit issue involving implementation of the controls as per the Permit requirements. The
various steps involved in the process are identification and completing all worksite preparations
(energy isolations, temporary defeats, etc.).
Authorize PTW: Process of authorization of the work permit by Area Authority (AA) ensuring
implementation of necessary permit controls.
Communicate Controls & Commence Work: An on-site walk through between Permit Issuer (PI)
and Job performer (JP) to demonstrate that worksite is safe to commence work. The process also
includes communication of all relevant hazards and controls by the JP to the Work Party.
Dynamic Risk Assessment: An on-going process of identification whether safe working conditions
exist during execution of work. All personnel are authorized to ‘Stop the Work’ in case of unsafe
conditions.
Work Handover / Suspension / Extension: The process covers guidelines around work extension,
suspension and handover if work is complete. Roles and responsibilities of various personnel
involved are defined in detail.
Permit Closure & Hand back: The process of commencement of handover of worksite from JP back to
Asset Owner. The work permit is closed by JP post-handover of worksite to Asset Owner.
