Safety barries are structures or devices designed to prevent accidents, control traffic, and protect people from hazards in various environments. They include guardrails, bollards, crash barriers, and fencing, made from materials like steel, concrete, or plastic. Safety barriers are used on roadways, construction sites, industrial facilities, and public spaces to block or redirect vehicles, contain debris, and prevent unauthorized access to dangerous areas. They provide both physical protection and visual cues to enhance safety. Regular maintenance and compliance with safety standards ensure their effectiveness and durability.
