A safety sign is a visual symbol designed to communicate important information about safety and health. These signs are often used in workplaces, public areas, and construction sites to alert people to potential hazards, provide instructions, or indicate safe practices. Common types of safety signs include warning signs, prohibition signs, and mandatory signs, each serving a specific purpose. Safety signs are typically made from durable materials like plastic or metal to withstand various environmental conditions. They use clear symbols and colors, such as red for danger and green for safety, to ensure quick recognition. Proper placement of these signs is crucial for effective communication and accident prevention.
