Objective of the Presentation is to create awareness on 1. The functional safety standards 60079-29-3 which applicable for fire & gas detection to end-users. 2. Why gas detection should not be clubbed together with Process Control Standard IEC 61511 and the various standards applicable. 3. Gas dispersion & placement of Gas detectors & role of gas detectors in risk reduction. 4. Technologies used in Flame & gas detection Topics Covered:- 1 Gas Dispersion & Sensor Placement 2 Principle of Operation – F&G System 3 Risk reduction & Role of F&G detectors 4 Functional Safety Standards for F&G and Projects. 5 Decision Making on Type Of F&G System 6 Applications of F&G Detectors 7 Why Using PLC's may generate trouble?
