A method for analyzing a system for safety to personnel is disclosed comprising: identifying at least one operating parameter of a first subcomponent of said product; identifying an inherent hazard of said first subcomponents based on an analysis of the at least one operating parameter; identifying features of the structure or operation of the subcomponent corresponding to the inherent hazard; identifying design modifications for the identified features that would mitigate the inherent hazard; identifying safety instrumented control functions and their probability of failure requirements that would mitigate the inherent hazard; prioritizing the identified features with respect to the effect that each of said features has on safety of the product; and determining whether an unsafe condition could result from the inherent hazard.

Method for assessing reliability requirements of a safety instrumented control function

A method for analyzing a system for safety to personnel or other systems is disclosed comprising: identifying at least one operating parameter of a first subcomponent of said product; identifying an inherent hazard of said first subcomponents based on an analysis of the at least one operating parameter; identifying features of the structure or operation of the subcomponent corresponding to the inherent hazard; identifying modifications or controls for the identified features which would mitigate the inherent hazard; prioritizing the identified features with respect to the effect that each of said features has on safety of the product; and determining whether an unsafe condition could result from the inherent hazard.
