Hazard and Operability (HAZOP) and similar studies have aleatoric and epistemic uncertainties due to their nature designed in the qualitative hazard analysis principle. These uncertainties directly affect the quality of the study and the variability of analyst experience and interpretations in the hazard analysis. In these studies, the linguistic effect on the accuracy and accuracy of the data obtained during the identification of the frequency or severity of the hazards is important to the extent that it will affect the quality of the study.
