HAZOP – Hazard and Operability Study

As we face hazards with the potential to harm and damage ourselves, our organisation and our environment, it is crucial to be able to manage these hazards. Hazard identification is one way to manage the hazards we are facing. Being able to identify the hazards in our daily life, will help us to manage them the in best way possible. When in need of a detailed identification of the potential hazards within our work, the HAZOP is a great methodology that can be used.

What is a HAZOP?
HAZOP stands for Hazard and Operability Study. It is a meticulous and in-depth approach utilized to identify potential hazards and assess risks within a process or system throughout its design or operational phase. A HAZOP is performed more in detail and focuses on each individual element of a system or process. Its purpose is to detect any deviations from normal operating conditions that could lead to hazards or undesirable consequences. Like the HAZID, it is typically conducted by a multidisciplinary team with in-depth knowledge of the system or process being assessed.

How to make a HAZOP?
The way to make a HAZOP typically involves the following steps:

  1. Defining the system or process being assessed and establishing the analysis’s objectives and scope. (HAZOP vs HAZID Studies)
  2. Assembling a multidisciplinary HAZOP team, including people with a variety of expertise.
  3. Systematically identifying each individual element of the system or process.
  4. Identifying potential deviations from normal operating conditions and comprehending their consequences, including hazards and undesirable consequences.
  5. Evaluating the hazards and risks linked to each identified deviation.

When to use HAZOP?
Just like other hazard identification methodologies, the HAZOP is a good option, for identifying potential hazards that can affect a project. The HAZOP is methodology that is more detailed with a focus on each individual element of the system or process. Therefore, it is very useful, especially if you need a more detailed identification of individual elements in a process or in a project.
