A safety barrier is a physical structure designed to prevent accidents and protect people from hazards. Commonly used in various environments, such as construction sites, roadways, and industrial areas, these barriers can be made from materials like concrete, metal, or plastic. Their primary purpose is to keep individuals safe by restricting access to dangerous zones or by absorbing impact during collisions. In addition to protecting people, safety barriers also help to manage traffic flow and maintain order in busy areas. Examples of safety barriers include guardrails on highways, fencing around construction sites, and bollards in pedestrian zones. These structures play a crucial role in enhancing overall safety and reducing the risk of injuries.
