Which option best aligns with an inherently safer design approach to reduce risk?

• A. Retain all features
• B. Remove unnecessary complexity
• C. Add more components
• D. Increase manual controls

Answer: (B)

Inherently safer design aims to reduce risk at the source by changing the design so hazards are eliminated or minimized rather than relying on additional protections. Removing unnecessary complexity achieves this by streamlining the system, which lowers the number of failure modes, simplifies testing and maintenance, and makes operation more predictable. Fewer features and fewer components mean there are fewer things that can go wrong, and the overall behavior becomes easier to reason about. Other approaches tend to raise risk rather than reduce it. Keeping all features keeps the complexity intact, adding more components introduces new potential points of failure, and increasing manual controls increases reliance on human performance, which can be variable and error-prone. So removing unnecessary complexity aligns with the goal of making the design safer by design, reducing risk at the source.
