Functional Safety vs Operational Flexibility
Expand the operating envelope through Advanced Process Control and inherently safer design, never by reducing the integrity level of approved safety instrumented functions.

Regulations
Business Context
Safety Instrumented Functions establish predefined operating limits that
automatically place processes into a safe state when hazardous
conditions occur. Production requirements may occasionally require
greater operational flexibility near these limits.
The Contradiction
Stronger safety functions improve process protection.
Greater operational flexibility supports production objectives.
Why It Exists
Safety limits are intentionally conservative, while production
optimization often seeks to maximize the operating envelope.
Direction
Expand operational capability through improved process understanding,
Advanced Process Control, and inherently safer design rather than
weakening safety functions.
