HAZOP

Safe operations with expert HAZOP analysis

HAZOP is used both during the design stages of a new process or project, for major process modifications, also for during operation to identify what design assumptions could be replaced by operational evidence, and for periodic review of existing operations. The European-Norm EN 61882 and IEC 61882 standard is conventionally used. Most government regulators around the world recognise the HAZOP technique as an acceptable methodology for evaluating risk.

Mastering Safety and Efficiency with HAZOP
HAZOP, the Hazard and Operability study encompass a wide range of applications, from initial process design to ongoing operations. Failure to prioritise HAZOP analysis can result in unmitigated risks, hazardous substance releases, and unidentified hazards, all of which can have severe consequences.

Benefits of Our HAZOP Service

  • Minimises the risk of hazardous substance emissions
  • Reduces the impact of hazardous substance releases
  • Identifies hidden or non-obvious hazards through Hazard Identification and Risk Assessment

DEKRA's Approach to HAZOP

Our approach to HAZOP analysis is meticulous and tailored to your specific needs. Here's how we do it:
  • Process Evaluation: We start by reviewing your Process Safety Information (PSI) and identifying any missing data necessary for a comprehensive hazard identification and risk assessment.
  • Design Intent: Establishing the process's design intent, including safe operating parameter ranges.
  • Applying Guide Words: Applying guide words (No, Less, More, Reverse, etc.) to each process parameter to uncover deviations from the design intent.
  • Assessing Control Systems: Evaluating the effectiveness of your control and emergency systems in preventing undesirable process incidents.
  • Consequence Estimation: Estimating the severity and likelihood of undesired incidents, factoring in mitigation safeguards and conditional factors.
  • Risk Matrix: Utilising a risk matrix to gauge the relative risks of these undesired incidents.
  • Safeguard Recommendations: Determining the necessary safeguards and process improvements to bring risks to tolerable levels.
Our process safety specialists compile their recommendations based on industry best practices and your site's unique experience.

Applications

The Hazard and Operability (HAZOP) study is the most widely used Process Hazards Analysis (PHA) technique in the chemical, pharmaceutical, food, oil and gas, nuclear, and other process industries worldwide.

Team Approach

HAZOP is a brainstorming exercise in which individuals from different disciplines participate. It is vital for the HAZOP team to be limited in size (ideally six people or fewer, excluding the HAZOP facilitator and, if there is one, the HAZOP secretary). It is difficult to establish a maximum and minimum number of participants in a HAZOP, since the various functions necessary may be assumed in different ways in different organisations. Nevertheless, and as a very general criterion, it is safe to say that a HAZOP with fewer than three participants (excluding the HAZOP facilitator and secretary) cannot generate sufficient and meaningful discussion.

Frequently Asked Questions - HAZOP
Knowing what to expect before implementing a HAZOP analysis makes for a more successful and efficient process. To that end, here are some frequently asked questions and answers about how our HAZOP studies work.
Q: What is a HAZOP study?
A: The Hazard and Operability (HAZOP) methodology is a systematic team-based Process Hazards Analysis (PHA) technique that can be used to effectively identify and analyze the risks of potentially hazardous process operations. It is used during the design stages of a new process or project, for major process modifications and for periodic review of existing operations.
