HAZOP Training

As discussed in our previous article – HAZOP study in India | HAZOP consulting services India | Process safety design; The HAZOP methodology is a well established technique used throughout industry for hazard identification and risk assessment. HAZOP was originally conceptualized in the 1960’s by ICI and training/guidance on its use was initially published in the 1970’s following the Flixborough disaster where an inadequately designed modification led to a large vapour cloud explosion killing 28 people.

We, at Panorama Consulting with our highly experienced team of HAZOP leaders have conducted thousands of HAZOP studies for many clients across many industrial sectors.

It is a universally recognized fact that for any Company to succeed it must take a rigorously proactive approach to risk management. Over the last few years Companies and a number of Countries legislators have been focusing on Process Safety as a method to reduce the risks posed by hazardous industries.

Process Hazard Analysis (PHA) is recognized as being a critical tool in the implementation of a successful risk management system.

HAZOP Training:
It is important that HAZOP training for top leaders in companies to cover following aspects of process safety management:

  • How to apply advanced risk assessment techniques
  • Mechanics of dispersion, fire, explosion and toxic releases
  • The concept of Quantified Risk Assessment “QRA”
  • Hazard and Operability (HAZOP) study methodology
  • HAZOP team leadership

HAZOP Training Techniques & HAZOP Objectives:

  • Understand the concepts of Risk Assessment and Risk Management

  • The role of Fault Tree Analysis for multi-causation analysis
  • Applications for ETA and FTA
  • Failure data for use in QRA’s
  • Societal Risk and Individual Risk
  • Review of software available for Quantitative Risk Assessments

The entire HAZOP process typically starts with the engineering drawing(s) at the BEGINNING of the process, the feeds being the raw materials. Often as many as 3 or 4 P&ID’s may be tabled at one session to enable the HAZOP team to identify where streams are coming from on one or more P&ID’s and where they are going to on the next one or two P&ID’s.
Companies should consider the following activities to help them make the most effective use of the products of a study:

  1. Prioritize the analysis results
  2. Document the hazard evaluation study
  3. Develop a management response to the study
  4. Resolve the actions resulting from the risk management decision making process in a timely manner.

Sometimes, it is difficult to rank the safety improvement suggestions from Hazard Analysis studies because the techniques generally do not provide a definitive, quantitative characteristic which is useful for ranking utility & purposes.

A frequent problem faced by the users of the HAZOP study results is that the HAZOP company – study team creates a long list of items for management to consider implementing in order to improve safety. In cases where this occurs, decision makers can rightfully wonder whether these results are of any practical use to them. They may ask, “Where do we start?” or “Which are the most important suggestions?”

To help management make these decisions, an efficient HAZOP consulting company & its team should give them as much information as possible. One way to do this is to rank the results of the HAZOP study. Ranking the safety improvement recommendations from the study allows management to prioritize the immediate efforts for resolution and follow-up.

The two most common criteria for ranking the safety improvement recommendations of HAZOP study are:

  • The analysts’ understanding of the risk posed
  • The analysts’ perception of the risk reduction

The first criterion ranks items based on their associated level of risk – it makes sense to resolve the most important problems first. The second criterion ranks proposed improvements by how much they will benefit the facility, not necessarily on how serious the problem is.

“Hazops are only as good as the knowledge and experience of the people present. If they do not know what goes on, the hazop cannot bring out the hazards.”
