Risk Assessment of an Industrial Unit using Functional Hazard Analysis
Author(s):
Abstract:
Despite the comfort and relative prosperity that has brought to mankind by modern technologies, some risks and threats is also created. These risks and hazardous factors must be assessed and controlled using systematic risk assessment and management techniques. In order to analysis the system hazards, several techniques and methods have been developed which each one has their own strengths and weaknesses. One of the hazard analysis techniques which is categorized as qualitative techniques and inductively identify and analyze the system hazards is called Functional Hazard Analysis (FuHA). The primary purpose of the FuHA is to identify and mitigate hazards resulting from the malfunction or incorrect operation of system functions and can lead to occurrence an undesirable event. In this study, the functional hazards of an industrial unit were analyzed using FuHA technique. By implementing FuHA techniques in under study industrial unit, 17 functional failures were identified and In general, according to the severity of the different consequences of detected faults, 60 functional hazards were identified which seven cases, unacceptable, 17 cases, undesirable and 36 cases acceptable but needs revision was evaluated. The results of this study showed that FuHA technique has a good ability to identify and analyze the functional hazards of system and sub-system, particularly software subsystems.
