Which of the following is NOT a typical policy or practice associated with inherent safety design?

• A. Increasing energy release to improve throughput
• B. Substituting with less hazardous materials
• C. Minimizing quantities and energies
• D. Simplifying the system

Answer: (A)

Inherent safety design aims to prevent or minimize hazards at the source by thoughtful design choices that reduce energy, quantities, and complexity. The goal is to make the process safer without relying on add-on controls.

Increasing energy release to improve throughput is not aligned with this approach. Pushing for higher energy release raises the potential consequences of any release and contradicts the idea of designing the process to be inherently safer. It’s about reducing hazard potential, not amplifying it.

Substituting with less hazardous materials fits perfectly because it lowers the hazard at its origin. Minimizing quantities and energies reduces the amount of hazardous material or energy available to cause harm. Simplifying the system reduces complexity, making failures less likely and easier to manage. All of these are classic inherent-safety practices.

So the choice that does not fit the inherent-safety approach is the one involving increasing energy release.
