Hazard-based design focuses on designing to minimize hazard potential and energy release, not simply meeting performance criteria.

• A. Hazard-based design centers on cost reduction and schedule adherence.
• B. Hazard-based design only considers the maximum equipment capacity.
• C. Hazard-based design ignores energy release and focuses on aesthetics.
• D. Hazard-based design focuses on minimizing hazard potential and energy release rather than just meeting performance criteria.

Answer: (D)

Hazard-based design is about reducing the sources of danger in a process—the potential for energy release and the overall hazard that a system could present—by making design choices that inherently lower risk, not just ensuring the system meets functional performance criteria. The correct statement captures this approach by saying the design aims to minimize hazard potential and energy release rather than simply chasing performance metrics. In practice, this means selecting safer materials, reducing inventories, adding containment and barriers, or designing processes to be less energetic or more controllable, so the chances and consequences of an incident are lowered.

The other options don’t fit because they describe goals unrelated to hazard reduction: focusing on cost and schedule emphasizes project management rather than safety; prioritizing maximum equipment capacity centers on throughput instead of hazard control; and ignoring energy release while prioritizing aesthetics contradicts the safety-driven mindset of hazard-based design.
