abstract="This study evaluated the performance of 6 commercially available hard hat designs-differentiated by shell design, number of suspension points, and suspension  tightening system-in regard to their ability to attenuate accelerations during  vertical impacts to the head. Tests were conducted with impactor materials of steel,  wood, and lead shot (resembling commonly seen materials in a construction site),  weighing 1.8 and 3.6 kg and dropped from 1.83 m onto a Hybrid III head/neck  assembly. All hard hats appreciably reduced head acceleration to the unprotected  condition. However, neither the addition of extra suspension points nor variations  in suspension tightening mechanism appreciably influenced performance. Therefore,  these results indicate that additional features available in current hard hat  designs do not improve protective capacity as related to head acceleration metrics.<p /> <p>Language: en</p>",
