What do signal words such as "Danger" and "Caution" indicate in safety signage?

Signal words like "Danger" and "Caution" are specifically designed to communicate the level of risk associated with hazards. The word "Danger" indicates a high level of risk that could result in severe injury or death if proper precautions are not taken. Conversely, "Caution" suggests a lesser risk, prompting individuals to be aware and take necessary precautions to avoid potential hazards. Understanding these signal words is crucial for interpreting safety signage correctly and ensuring adherence to safety protocols. This differentiation helps individuals prioritize their responses and actions based on the severity of the hazards they might encounter.

While other options may pertain to important aspects of safety signage—like identifying what type of hazard is present or what safety equipment might be required—they do not directly relate to the meaning of the signal words themselves, which focus explicitly on the risk level. However, knowing which authorities are responsible for enforcement is also valuable, but it does not connect with the immediate interpretation of the signage in question.
