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

A physical hazard refers to a tangible condition or object that increases the likelihood of a loss occurring. In this case, slippery floors due to wet conditions constitute a clear example of a physical hazard. These floors create a risk of slipping, which can lead to injury or property damage, demonstrating how physical characteristics can contribute to potential dangers in a given environment.

The other options represent different types of risks. For instance, a fire alarm malfunction relates to a mechanical or operational issue, not a physical condition present in the environment. An unsuccessful advertising campaign is a business risk associated with marketing effectiveness rather than a physical hazard. Similarly, legal disputes over contract terms fall under legal or regulatory risks, lacking the physical aspect that characterizes physical hazards. Thus, the slippery floors exemplify a direct hazard due to their physical nature and potential for causing harm.
