Which term best describes the act of preventing future incidents through investigation?

The term that best describes the act of preventing future incidents through investigation is "preventative measure." This concept refers to actions taken to identify potential issues before they occur, addressing the root causes of problems based on insights gathered from previous incidents. By conducting thorough investigations, maintenance personnel can implement strategies designed to mitigate risks, enhance safety, and ensure that similar incidents do not recur in the future.

Preventative measures are crucial in park maintenance as they focus on creating an environment that minimizes hazards and optimizes operations. This could include regular inspections, employee training, and the development of best practices based on empirical data. In contrast, other options such as corrective action are more involved in addressing problems after they have already occurred, rather than emphasizing proactive prevention.
