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.
