Typical risk reduction methods found in process plants

2 The risk reduction factor for a BPCS (which does not conform to tEC 61511 ANSI/ISA-84.00.01-2004 (lEC 61511 Mod) or lEC 61508) used as a protection layer shall be below 10. [Pg.53]

NOTE When considering how much risk reduction credit to be given to a BPCS, consideration should be given to the fact that a part of the BPCS may also be an initiating source for an event. [Pg.53]

3 If a risk reduction factor of greater than 10 is claimed for the BPCS, then it shall be designed to the requirements within this standard. [Pg.53]
