What is HAZOP?

A Hazard and Operability (HAZOP) study is a structured and systematic review of an existing process or operation to identify and evaluate risks to personnel or equipment. A HAZOP study is done to review and pick up design and engineering issues that may otherwise not have been known. The HAZOP team lists potential causes and consequences from these issues. If existing safeguards fail to meet the criteria, the team recommends the action be taken to reduce the risk. HAZOP’s meticulous approach is commonly used with chemical production and piping systems.

 

Objectives of carrying out a HAZOP study are:

  • To check a design
  • To decide whether and where to build
  • To decide whether to buy a piece of equipment
  • To obtain a list of questions to put to a supplier
  • To check running instructions
  • To improve the safety of existing facilities

 

HAZOP Team

In addition to the Chairman and scribe, the HAZOP team comprises of the following personnel:

  • Process Designer/Engineer
  • Design consultant / Project Manager
  • Production Manager
  • Maintenance Manager
  • Discipline / Vendor Specialist (Chemical engineer, Electrical Engineer, Instrument Engineer, Quality Control Engineer)

 

A HAZOP study can be implemented on either new or existing facilities and processes. When done on a new process, potential causes of failure is highlighted. The HAZOP team will then produce a written assessment that lists all causes, consequences and protection requirements. In existing facilities, a HAZOP may be ongoing to continuously improve processes. In both cases, when a hazard is identified, recommendations are made.

 

Advanced HAZOP Masterclass is a 2-day course held from 15 – 16 October 2018 (Singapore) and 17-18 October 2018 (Kuala Lumpur), where refresher topics of HAZOP such as bowties, swiss cheese and LOPA, the human factors and the limitation of HAZOP and its operability are discussed. Participants will learn about the roles and responsibility of HAZOP team members and leaders, as well as participate in exercises on how to pick the best approach to safety study depending on different scenarios.
