A safety helmet is a type of personal protective equipment (PPE) designed to protect the head from injuries caused by falling objects, impacts, and compression. It typically consists of a shell, lining, chin strap, and accessories, and is widely used in various industries such as construction, mining, power, and mechanical manufacturing.
The concept of protective headgear dates back to ancient times when warriors used helmets to protect themselves in battle. The modern safety helmet, however, emerged in the early 20th century with the industrial revolution. In 1919, the E.D. Bullard Company in the United States invented the first steel helmet for industrial use. Over the years, advancements in materials and design have led to the development of lighter, more durable, and more comfortable safety helmets that offer better protection against a variety of hazards.
The primary purpose of a safety helmet is to protect the wearer's head from injuries caused by falling objects, impacts from collisions, and compression in confined spaces. They are essential in environments where there is a risk of head injury, such as construction sites, manufacturing facilities, and mining operations. Additionally, some safety helmets are designed to provide protection against electrical hazards, extreme temperatures, and chemical exposure.
