What term refers to an undesired event that could have led to personal harm or property damage under slightly different circumstances?

The term that best describes an undesired event that could lead to personal harm or property damage under slightly different circumstances is "Near Miss." A near miss occurs when an incident nearly results in an undesirable outcome, such as injury or damage, but ultimately does not. This concept is important in risk management and safety programs, as it highlights potential areas for improvement and preventative measures.

Recognizing near misses helps organizations identify risks and implement safety protocols, as these events can indicate vulnerabilities that, if not addressed, could lead to actual accidents in the future. By focusing on near misses, safety professionals can proactively mitigate risks and enhance overall safety in the workplace.

In contrast, the other terms relate to different concepts: an incident generally refers to any unplanned event that disrupts normal operations, an accident implies an unintentional event that results in harm or damage, and a hazard refers to a potential source of harm. While these terms are related, "Near Miss" specifically encapsulates the scenario described in the question, where harm was narrowly avoided.
