Reliability: TGMS - Design & Integration Safety Goals • A Toxic Gas Monitoring System is composed of sensors, logic solvers, and final control elements designed for the purpose of taking the HPM process gas system to a safe state when predetermined conditions are violated. • A TGMS requires absolute reliability to ensure that all safety aspects of the system are operational and “available” at all times. • No “covert” or “fail-danger” faults are permitted • All gas sensors and gas detection instruments are continuously “supervised” – to ensure continuous gas monitoring “availability”. • Sensor/instrument/field device/control system diagnostics are utilized throughout the design, combined with “fail-safe” wiring practices. • TGMS faults – issue immediate local and remote notification alerts. 2012 NE SESHA Conference
TGMS – Reliability TGMS and Process Control/Building Management System (BMS) Separation: • Safety Control is: Passive Dormant Controlled (limited accessibility) In need of Periodic Testing (similar to a FAS) • Safe failures are: Initiating Overt Spurious (Trips due to hardware/software fault, transients) Dangerous failures are: Inhibiting Covert Potentially dangerous Must be found by testing 2012 NE SESHA Conference
