Which of the following factors is NOT considered in nominal safety approaches?

Nominal safety approaches focus primarily on established standards, regulations, and practices rather than examining broader historical trends. Therefore, when evaluating safety measures, the emphasis is typically placed on design criteria, standardization, and adherence to policies, all of which contribute to a baseline level of safety and compliance with current regulations.

Long-term historical trends, on the other hand, are not a primary consideration in nominal safety approaches. This is because nominal safety approaches rely more on the current state of safety practices and regulatory adherence rather than analyzing how past incidents or historical data might inform present or future safety protocols. By not taking into account these long-term trends, nominal safety approaches may overlook critical insights that could lead to more effective safety improvements.
