Qualitative hazard analysis is mainly utilized during the early stage of the project in its life cycle. Preliminary hazard analysis has been used extensively for early-stage hazard analysis in many industrial plants. In preliminary hazard analysis, hazards are identified, listed, and then analyzed with respect to their occurrence, frequencies, and consequences. Based on the risk matrix, risks are ranked. Based on risk ranking, control measures are developed. “What if” is based around brainstorming analysis by a small team of highly experienced engineers, but it is not systematic. Here, hazards are identified with the help of answering a set of questions asked in the form of “What if.” After frequency ...
