Industrial safety is paramount in any operation involving hazardous chemicals or complex processes. One of the most effective techniques for safeguarding industrial facilities is the Hazard and Operability (HAZOP) study. This systematic, structured method identifies potential hazards and operability issues that could lead to accidents, helping organizations mitigate risk before incidents occur. In this article, we explore the principles behind HAZOP, outline best practices for conducting effective studies, and discuss how this methodology can be integrated into broader safety management systems to enhance industrial safety.
