Ergonomics and System Safety chapter - Essay Example

Fault trees are graphical presentation of pathways within a structure or a system that might lead probable, adverse loss event. This graphical presentation shows interconnection of event, conditions and circumstances that jointly contributed to the tragedy. It utilize standard logic cryptogram in development while attaching probabilities to the occurrence of this events that lead to the undesirable loss. It is one of safety analytical tool most used in areas where high risk is perceived, where the number of contributory events is large and where the undesirable events have already been identified (Break 47).

This paper will main emphasis on developing a fault tree and later develop a job safety analysis page. In order to achieve the set objectives this paper will analyze a recent case of “Grain elevator explosion kills 3” as illustrated below; As illustrated above a fault tree establishes the contributory events thus offering remedial actions so to prevent the occurrence of undesirable loss again.Part B: Job Safety Analysis Job safety analysis is tool to manage risk associated with a specific job position, where the hazards that on faces in the work place is measured and then ways to eliminate the risk are developed and implemented (Vincoli 42).
