A safety helmet is a protective headgear designed to safeguard the wearer from injuries caused by falling objects, impacts, or electrical hazards. Commonly used in construction, manufacturing, and various outdoor activities, these helmets are made from durable materials like polycarbonate or fiberglass. They often feature a hard outer shell and an inner foam lining to absorb shock. Safety helmets are equipped with a chin strap and adjustable suspension system to ensure a secure fit. Many models also include ventilation holes for comfort and can be fitted with accessories such as face shields or earmuffs for additional protection. Proper use of a safety helmet is essential for workplace safety and compliance with regulations.
