I had a hallway discussion at a recent safety
standards committee meeting about how to implement the safety
life cycle. One of the fundamental concepts in the safety
life cycle is risk-based design. Process risk is evaluated
and risk reduction targets (safety integrity levels, SILs)
are selected for each safety loop. The resulting safety
design is verified against the SIL target using an analysis
of hardware failure rates, failure modes and diagnostic
coverage. This system provides verification in a closed-loop
method that control engineers can certainly
understand.
The SIL verification process using failure rate
