Explain why hard hats with lateral protection are better than the traditional hard hat
What will be an ideal response?
Originally introduced in 1919, the hard hats first used for head protection in a construction setting were inspired by the helmets worn by soldiers in World War I. Such early versions were made of varnished resin-impregnate canvas. As material technology evolved, hard hats were made of vulcanized fiber, then aluminum, and then fiberglass. Today's hard hats are typically made from the thermoplastic material polyethylene, using the injection-molding process. Basic hard hat design has not changed radically since before World War II. They are designed to provide limited protection from impact primarily to the top of the head, and thereby reduce the amount of impact transmitted to the head, neck, and spine.
