Presented at AIChE 2017 Spring Meeting, and Global Congress on Process Safety 2017.
A core attribute of all safeguards is that they must be functional against the loss event in question and one of the essential elements of functionality is speed. How to determine the response time available for a given safeguard to complete its action is a common project question. Several instrumentation and controls design pitfalls should be avoided when specifying the response time. A variety of engineering practices, from basic to advanced, may be used to justify the selected value.
