A safety helmet, commonly referred to as a hard hat in industrial settings, is an essential item of personal protective equipment (PPE) designed to safeguard the wearer's head from injury. Its primary function is to mitigate risks associated with falling objects, impacts against fixed structures, and electrical hazards. Composed typically of a durable plastic shell and an internal shock-absorbing suspension system, the helmet works by distributing impact energy across its structure rather than channeling it directly to the skull. These helmets are mandatory across high-risk sectors such as construction, manufacturing, and mining, ensuring compliance with critical safety standards like those set by the Bureau of Indian Standards (BIS), and are categorized into specific types based on the level of impact and electrical protection they offer.
