The information used to compile the safety case may then formally guarantee further specifications, such as maximum safe speeds, permitted safe loads, or any other operational parameter. A safety case should be revisited when an existing product is to be re-purposed in a new way, if this extends beyond the scope of the original assessment.
A job safety analysis (JSA) is a procedure that helps integrate accepted safety and health principles and practices into a particular task or job operation.The goal of a JSA is to identify potential hazards of a specific role and recommend procedures to control or prevent these hazards.
A reliability engineer has the task of assessing the probability of a plant operator failing to carry out the task of isolating a plant bypass route as required by procedure.
The analysis is used during the design phase to identify process engineering hazards together with risk mitigation measures. The methodology is described in the American Petroleum Institute Recommended Practice 14C Analysis, Design, Installation, and Testing of Basic Surface Safety Systems for Offshore Production Platforms.
The notation was further developed and expanded by Tim Kelly, whose PhD thesis contributed systematic methods for constructing and maintaining GSN diagrams, and the concept of ′safety case patterns′ to promote the re-use of argument fragments. [2]
A worst-case circuit analysis should be performed on all circuitry that is safety and financially critical. Worst-case circuit analysis is an analysis technique which, by accounting for component variability, determines the circuit performance under a worst-case scenario (under extreme environmental or operating conditions).
The case stemmed from a lawsuit filed by Joseph Fischer – a former police officer and one of more than 300 people charged by the Justice Department with "obstruction of an official proceeding ...
