Description:
A helmet, also known as Hard hat, is protective equipment worn on the head to prevent injuries in hazardous environments. It is commonly made from strong materials such as high-density plastic or fiberglass and includes components like a hard outer shell, an internal suspension system, and a chin strap. Helmets are widely used in construction, industrial work, mining, and other high-risk activities to protect against falling objects, impacts, and electrical hazards. Some helmets also include additional features such as face shields, ear protection, or ventilation openings.

Operation:
The operation of a helmet is based on absorbing and distributing the force of impact. When an object strikes the helmet, the hard outer shell spreads the force over a larger area, reducing the intensity of the impact. The internal suspension system acts as a shock absorber, creating space between the shell and the head to further reduce injury. The chin strap helps keep the helmet securely in place during movement or impact. This combination of features ensures that the head is protected, minimizing the risk of serious injury in dangerous working conditions.
