A hard hat is a type of protective helmet worn on construction sites and other hazardous environments. It is designed to shield the head from falling objects, bumps, and electrical hazards. Made from durable materials like plastic or fiberglass, hard hats often come in various colors, which can indicate different roles or levels of safety training among workers. Wearing a hard hat is essential for ensuring safety in industries such as construction, mining, and manufacturing. In addition to head protection, many hard hats can be equipped with accessories like face shields, ear protection, and lights, making them versatile tools for workers in challenging conditions.
