Hazard signs are visual indicators used to warn people about potential dangers in a specific area. These signs often feature bright colors, such as yellow or red, and symbols that convey the type of hazard present, such as toxic substances, flammable materials, or electrical hazards. Their primary purpose is to promote safety and prevent accidents 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, helping to protect both individuals and property.
