HAZID Preparation Safety Requirements

HAZID Preparation Safety Requirements

In a previous blog, we have discussed HAZOP preparation safety requirements, one of the various Hazard Effects Management Process studies carried out in process industries to assess and evaluate potential hazards. Today we take a closer look at HAZID preparation safety requirements.

The HAZOP (Hazard Operation) review primarily focuses on operational issues. HAZID (Hazard Identification) focuses on identification of hazards especially with respect to Major Accident Hazards (MAH) and is usually undertaken for any project that deals toxic, combustible or flammable material.

The objective of the HAZID is to identify any hazard that could result in the loss of containment, injury to persons or damage to equipment/ structures; assess the conditions which may cause a hazardous situation during normal operation and maintenance and assess the probability and possibility of equipment failure and the consequential effects on environment, human life and production, and loss of capital.

In order to conduct the HAZID study, it is essential that the project owner provides detailed process information including:

  • Basis of Design
  • System Design Philosophies
  • Plot Plans, General Arrangements
  • Process flow diagrams (PFD)Utility flow diagrams (UFD)
  • Procedures relevant the objective of the HAZID

During the HAZID workshops, the team evaluates:

  • Layout and segregation/separation with respect to the hazards
  • Controls and safeguards to prevent or limit the occurrence of the MAHs
  • Mitigating measures to reduce adverse effects of potential of MAHs
  • Recovery and emergency response with respect to MAHs
  • Escape for credible accident scenarios.

The HAZID team consists of members of the project engineering team plus an independent Chairman (or Facilitator) and a Secretary (or Scribe). The Chairman must be an independent party with no direct involvement with the project execution. He or she must have the appropriate level of experience in conducting HAZID or HAZOP reviews of similar facilities.
The Secretary should have an appropriate level of experience or training for acting as a HAZID secretary. The Secretary attends and minutes the HAZID review sessions and the Chairman prepares the report.

Dome International LLC has a team of highly qualified Safety & Risk Consultants and has provided both Chairmen and Scribes for a large number of workshops undertaken for the Oil & Gas industry as well as other process industries. These workshops are often part of larger Health, Safety & Environmental Impact Assessments (HSEIA) awarded to Dome but can also be standalone contracts.

Recent examples include:

  • HAZID registers for Haliba FFD Project as part of the Al Dhafra HSEIA Phase 2 & 3 for the Haliba Full Field Development Project.
  • HAZID / HAZOP, BowTie, SIMOPS, ALARP Workshops as part of the Phase 1 HSEIA for Technip / ADNOC Dalma Gas development Project
  • HAZID Review studies as part of a wide range of Safety & Risk Studies undertaken for the NASR Full Field Development Project.
  • HAZID, Bow Tie, MOPO Workshops undertaken as part of the Safety Case for Sibo Field Development Project, Iraq. Client: Kuwait Energy Limited
  • HAZID / BowTie Workshop as part of Phase 1 HSEIA study for ADNOC underground crude oil storage project in Fujairah.
  • HAZID / HAZOP / SIPMOPS / MOPO / BowTie Workshop as part Phase 2 and Phase 3 HSEIA and Safety Studies for Al Dabbiya Field Development.
  • HAZID / HAZOP / SIL Workshop as part of Phase 1 HSE studies for Zakum Oil Line Replacement Project.
