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

The example of an environmental physical hazard is best represented by the presence of asbestos in an old house. Asbestos is a naturally occurring mineral that poses serious health risks when its fibers are inhaled. This makes it a direct environmental hazard to individuals living or working in that space, especially if it is disturbed during renovations or deterioration.

In contrast, potholes in the road, while they do create unsafe driving conditions and may lead to physical accidents, are not categorized as environmental hazards in the same way that asbestos is. They represent a condition that affects vehicular safety rather than a direct environmental health risk. Poorly maintained engines can lead to mechanical failures or accidents, but they pertain to mechanical hazards rather than environmental ones. Working in a coal mine certainly presents risks, but the primary concerns there are usually related to occupational hazards rather than environmental ones specific to context.

Thus, the recognition of asbestos as an environmental physical hazard comes from its well-documented status as a risk factor for serious lung diseases, making it a clear example of potential danger in the environment.
