What is the focus of a Hazardous Operations Study (HAZOPS)?

1. To assess operational efficiency

2. To identify and evaluate hazards in operations

3. To train personnel on safety measures

4. To develop emergency response plans

The correct answer is: To identify and evaluate hazards in operations

A Hazardous Operations Study, commonly known as HAZOP, primarily focuses on identifying and evaluating hazards that could pose risks in operational processes. This systematic technique involves a detailed examination of how deviations from the intended operation can lead to potential hazards. It analyzes different process variables and examines their deviations to determine what could go wrong, why, and what the consequences might be. The emphasis on identifying and evaluating hazards allows organizations to put measures in place to mitigate risks effectively, ensuring that processes are not only efficient but also safe. This proactive approach aids in preventing accidents and minimizing risks associated with hazardous operations, thus making safety an integral component of operational planning and execution. The other options, though important in their contexts, do not specifically align with the primary purpose of a HAZOPS study. While operational efficiency, training on safety measures, and emergency response plans are all crucial aspects of safety management, they are not the core focus of the HAZOPS methodology. Instead, HAZOPS specifically aims to dissect operational processes for hazard identification and risk evaluation, forming a critical step in enhancing workplace safety.
