Process Safety



Process Safety

Managing Health, Safety and Environment (HSE) aspects in Engineering, Procurement and Construction (EPC) Projects have great challenges particularly in the technical and cost. Managing HSE risks is very significant in controlling the cost and technical integrity. Losses caused by lack of control of HSE risks can be devastating to people, assets, reputation and the environment. To achieve a successful business we must achieve an outstanding HSE performance in design as well as in construction activities.
Process Safety team in IMEN FIDAR looks into the design details for safe operation of a plant during all stages of project.
Process Safety Department is an engineering function and is a part of the Technical Services. The Organisation Chart for the Process Safety Department is as follows:

Main Activities in Process Safety Department:

1- Hazard Identification Study (HAZID)
HAZID Study (Hazard Identification) is a technique for early identification of potential hazards and threats.
The HAZID study is carried out by a team of competent engineers from a mixture of disciplines and is led by a person who is experienced in the HAZID technique.
Hazard identification involves two key tasks:

  • Identification of specific undesirable consequences and
  • Identification of material, system, process, and plant characteristics that could produce those consequences.

2-Hazard & Operability Study (HAZOP)
HAZOP is a systematic method for examining complex facilities or processes to find actual or potentially hazardous procedures and operations so that they may be eliminated or mitigated. It relates to a qualitative assessment of risk based on judgment of threats, such as hardware failure, control system failure, human error, corrosion, extreme conditions, etc.

3- Consequence Analysis
Consequence analysis is activity for calculation or estimation of numerical values that describe the credible physical outcomes of loss of containment scenarios involving flammable, explosive and toxic materials with respect to their potential impact.
Software: PHAST 6.7 & FLARESIM 3.02
4- Quantitative Risk Assessment (QRA)
Quantitative Risk Assessment (QRA) is derived from the product of frequency of occurrence (chance) and potential consequence. QRA technique can be defined as the formal and systematic approach to identifying hazards, potentially hazardous events, and estimating likelihood and consequences to people, environment and assets, of incidents developing from these events.

5- Safety Integrity Level (SIL)
Safety Integrity Level is a way to indicate the tolerable failure rate of a particular safety function. Standards require the assignment of a target SIL for any new or retrofitted SIF (Safety Instrumented Function) within the SIS (Safety Instrumented System). The assignment of the target SIL is a decision requiring the extension of the Hazards Analysis. The SIL assignment is based on the amount of risk reduction that is necessary to maintain the risk at an acceptable level. All of the SIS design, operation and maintenance choices must then be verified against the target SIL. This ensures that the SIS can mitigate the assigned process risk.
Software: PHA-Pro 7
6- FIRE PROTECTION AND PREVENTION
Design of all active and passive fire protection systems include:
  • Plant Equipment Layout & Spacing
  • Hazardous Area Classification
  • Escape, Evacuation and Rescue Plan
  • All Fire Fighting Systems (Water, Foam, Dry Chemical & Gaseous Systems)
  • Plant & Personal Safety Equipment (PPE, Safety Sign, Safety Shower & Eye Wash, Wind Socks and other)
  • Fire Proofing
  • Fire & Gas Detection System
