What type of hazard do warning signs aim to address?

Warning signs are specifically designed to address potential hazards. These signs are used to alert individuals to dangers that may not be immediately evident but could pose risks if ignored. For instance, a warning sign indicating "Caution: Wet Floor" addresses the potential hazard of slipping, which could lead to injury. The purpose of these signs is to make individuals aware of ongoing conditions that are not currently harmful but might lead to dangerous situations if precautions are not taken.

In contrast, the other options refer to more specific types of dangers or situations that may not be as broad. Emergency hazards pertain to situations that require immediate response, physical hazards relate to risks posed by objects or conditions in the environment, and chemical hazards denote risks associated with exposure to dangerous substances. While these are important areas of safety, warning signs focus more on alerting individuals to potential risks that could occur and encouraging them to take preventive actions.
