Abstract
This study will address the issues, decisions, and challenges encountered when attempting to initially apply the concepts of the safety life cycle management (SLCM) analysis technique to the design of a safety instrumented system (SIS) for safer plant operations and thereby, focuses in the search of implication prospects of SLC model to overcome the induction hazards (hazards associated with the induction furnace) during the foundry operations of a manufacturing set-up. This study is conducted based on the SLC model of IEC 61508 safety standard consisting of three broad phases analysis, realization and operation phases for the safe operation of induction furnace. With the SIS's architecture of more diagnostics plus redundancy designed for the increased safety integrity level (SIL), as interpreted from the study, increased plant safety, reduced risk and better operational performance, all these can be achieved against the induction hazards during the foundry operations. The implication of SLC model will gain significant momentum in terms of overall safety and can benefit the industrial set-ups as a whole.
