Regulations

Business Context

Additional safety barriers improve protection against major accidents

but also increase inspection, testing, calibration, and maintenance

requirements throughout the lifecycle of the facility.

The Contradiction

More safety barriers improve process resilience.

More barriers increase maintenance effort and system complexity.

Why It Exists

Organizations frequently respond to emerging risks by adding new

protective systems rather than simplifying process design or eliminating

hazards.

Direction

Strengthen protection by simplifying hazards, improving barrier

independence, and reducing unnecessary system complexity.
