According to safety standards, what are the two main functions of head protection?

The two main functions of head protection, particularly in the context of safety standards such as those set by organizations like OSHA, are to resist penetration and absorb the shock of a blow. These functions are critical in protecting the wearer from impacts, falling objects, and hazardous situations that could potentially lead to serious injuries.

Head protection, often in the form of hard hats, is designed with materials that can withstand significant forces, preventing objects from penetrating through to the skull and brain. Additionally, in the event of an impact, these helmets are engineered to absorb the energy from the blow, thereby reducing the risk of concussion or other head injuries. This protective design is essential for workers who are exposed to overhead hazards, making it vital to adhere to these safety standards to ensure overall workplace safety.

While other options like visibility or adjustability are beneficial traits in head protection, they do not fulfill the primary purpose of injury prevention that is defined in safety standards.
