Which strategy relies on built-in features to reduce risk without the need for ongoing human intervention?

The correct answer is rooted in the concept of passive safety systems, which are designed to function automatically without relying on human action. These systems incorporate built-in features that inherently reduce risk by utilizing physical principles or existing conditions to manage hazards.

For example, a passive safety system might involve design elements that automatically contain a spill or mitigate a fire without the requirement for continuous monitoring or manual operation. This contrasts with active systems that require continual human input and maintenance to function effectively.

In a more general sense, passive strategies enhance safety by integrating risk reduction measures directly into the design of facilities or processes, promoting a safer environment with minimal reliance on human intervention. This characteristic makes passive strategies particularly effective in scenarios where human error could exacerbate risks.
