Codes and Standards Update: Safety Instrumented Burner Management Systems (SI-BMS)

Invoking the concept of a Safety Instrumented – Burner Management System in all three of the NFPA 85, 86 and 87 series of codes / standards is a significant milestone for industry. This paper will explain changes as they apply to the concepts of Safety Instrumented Systems and include a discussion on equivalency clauses and / or linking paragraphs to ISA S84.00.01 – 2004 (IEC 61511 Mod) possibly allowing deviation from prescriptive requirements. Modification of logic solver requirements with inclusion of a direct reference mandating the use of Safety PLCs with minimum SIL capabilities in certain instances and changes related to sensors and valve requirements will be shared. This paper will also highlight areas where the concepts of Safety Instrumented Systems in the author’s opinion have been potentially misapplied within the NPFA series.
