Course Description

The concept of a Safety Instrumented Fire & Gas Systems (SI-FGS) has emerged in the process industry. Its arrival is has generated both controversy and confusion. The term SI2 of 13FGS represents the attempted application of perfo rmance based safety concepts to the design of Fire & Gas Detection Systems. ANSI / ISA S84.01 states that Fire & Gas Systems where operation action is required to initiate the system is not covered by the standard. Thus, those systems that automatically initiate an action could be addressed by the performance based Safety Instrumented System standards. However, the inherent differences between a Safety Instrumented System and a Fire & Gas System pose some challenges for an end user attempting to merge design techniques.
A Safety Instrumented Fire & Gas System (SI-FGS) is a system comprised of initiating device sensors, logic solvers, final control elements, fire safety functions and / or notification appliances for the purpose of mitigating an event when predetermined conditions are violated.
The Fire and Gas system (FGC) is designed to give the earliest possible warning and location of a fire in its initial stage, a flammable gas leakage or accumulation up to the lower explosive limit (LEL %) and any toxic gas likely to be present up to the occupational exposure limits (OEL).
