Process safety: Blind spots and red flags

摘要

The Process Safety Management (PSM) regulation 29 CFR 1910.119 was developed in response to a series of major accidents. These same events led to the creation of the safety instrumented system (SIS) standard, ANSI/ISA-84.00.01-2004 Part 1 (IEC 61511-1 Mod). Both provide a wholistic, lifecycle approach to the design, operation and maintenance of SIS and facilities. Plant safety improves when these programs are implemented, although accidents can still occur.
