Cap made of rigid, strong materials such as vulcanized fiber, glass fiber or plastic, which protects a worker from injury caused by falling objects, large chips, or by striking the head against projecting materials. The cap has a cradle to cushion the shock of blows and a sweat band to absorb perspiration; it is water resistant and nonconductive. A front visor shields the face and eyes from overhead glare, and makes the cap suitable for wear in close, confined spaces where a full brim might interfere.
