What does the Prohibition Sign communicate?

The Prohibition Sign is primarily used to convey actions that are not permitted or must be avoided in specific areas or situations. These signs typically feature clear symbols and specific wording to express things that one must refrain from doing, such as "No Smoking" or "No Entry." This clear, direct communication of prohibited actions is essential for maintaining safety and compliance within various environments, such as construction sites or industrial areas.

In contrast, the other choices relate to different types of safety information. Important information on safety protocols may be found in instructional or mandatory signs, while information about extinguishers is typically conveyed through specialized signage or labels focused on fire safety. Similarly, awareness of hazards is usually indicated by warning signs, which identify risks rather than prohibitive actions. Thus, the Prohibition Sign's core function aligns with indicating what actions must be avoided, emphasizing its critical role in promoting safety.
