Which of the following is an example of a physical hazard?

The identification of a physical hazard refers to a tangible condition that can lead to a loss or increase the likelihood of an accident. In this context, opting for unsanitary conditions leading to disease exemplifies a physical hazard because it encompasses direct environmental factors that can contribute to harm, such as the presence of waste, lack of cleanliness, or cluttered spaces that could injure individuals or lead to health issues.

Physical hazards are often contrasted with moral hazards, which involve behavior or decision-making that increases risk, such as poor moral values or deliberately taking risks. Similarly, driving under the influence is considered a behavioral issue that significantly impacts safety but does not define a physical hazard in the same way that unsanitary conditions do. Leaving a car unlocked represents a risk related to theft rather than a physical hazard affecting individuals' safety directly. Thus, the nature of unsanitary conditions as a clear and observable environmental factor justifies why this choice accurately represents a physical hazard.
