Safety Instrumented System Architecture Diagnostics
Jim Cahill
The language of process safety is filled with its own jargon. Architectures are described as 1oo1, 1oo2, 2oo2, 2oo3, etc. The “oo” means “out of”. So, 1oo1 means one-out-of-one. William M. Goble and Harry Cheddie wrote a book, Safety Instrumented Systems...
