HAZOP, or Hazard and Operability Study, is a structured and systematic technique used to identify potential hazards and operability issues in processes and systems. Originating in the 1960s, hazop was developed as a means to enhance safety in chemical processing plants. The methodology involves a team of experts who analyze a process by breaking it down into its individual components and examining how deviations from the intended design can lead to hazardous situations.

This approach is particularly valuable because it encourages collaborative thinking and leverages the diverse expertise of team members, leading to a more comprehensive understanding of potential risks. The HAZOP process typically involves several key steps, including defining the scope of the study, assembling a multidisciplinary team, identifying nodes within the process, and applying guide words to explore possible deviations. Each node represents a specific part of the process, such as a piece of equipment or a stage in production.

The guide words—such as “more,” “less,” “as well as,” and “none”—serve as prompts to stimulate discussion about how variations in process parameters could lead to unsafe conditions. By systematically addressing these deviations, HAZOP studies can uncover hidden risks that might not be immediately apparent, thereby enhancing overall safety and operability.
