Hazard signs are visual indicators used to warn people about potential dangers in a specific area. They often feature bright colors, such as yellow or red, and symbols that convey the type of hazard, such as toxic substances, flammable materials, or electrical hazards. These signs help ensure safety by alerting individuals to take necessary precautions. Common types of hazard signs include warning signs, which indicate a general risk, and prohibition signs, which inform people of actions that are not allowed. Understanding these signs is crucial for maintaining safety in workplaces, construction sites, and public areas.
