A hard hat is a type of protective headgear designed to safeguard the wearer from injuries caused by falling objects, bumps, or electrical hazards. Commonly used in construction sites, factories, and other hazardous environments, hard hats are made from durable materials like high-density polyethylene. They often feature a suspension system that helps absorb impact and provides a comfortable fit. Hard hats come in various styles and colors, with some designed for specific industries or tasks. Many hard hats also include additional features, such as slots for attaching accessories like face shields or ear protection. Compliance with safety standards, such as those set by OSHA or ANSI, is essential for ensuring their effectiveness.
