This second edition of Helmets: a road safety manual for decision-makers and practitioners has updated the evidence on risk factors and interventions for helmet use. The manual is aimed at policy-makers and road safety practitioners and draws on experience from countries that have succeeded in promoting helmet use. The effectiveness of helmets in reducing head injuries and preventing death has been established by several found by several studies. However, ensuring the use of helmets requires additional interventions. These include developing and passing a law for helmet use among PTW users, developing helmet standards suitable for all age groups and appropriate for the local weather, enforcement of the law by police, and education programmes to increase awareness of the law and benefits from its compliance.

This wonderful new survey follows the evolution of the sports helmet from early military and aviation uses, through early motorcycle and auto racing, and to modern helmets used in a wide variety of sports today. The science of helmet design and manufacture is covered before moving into the art of the helmet. Helmets for six major sports are extensively covered: auto and motorcycle racing, bicycling, equestrian activities, skiing, football, and ice hockey. Some lesser known sports and their helmets are also included to give a fascinating and complete panorama of the field. The design innovations, both for safety and appearance, the colors, and the fascinating history will engage the reader, while nearly 600 color images will please even the most particular sports fan. For designers, players, scientists, and historians this book is a true delight.

Combat helmets have evolved considerably over the years from those used in World War I to today's Advanced Combat Helmet. One of the key advances was the development of aramid fibers in the 1960s, which led to today's Kevlar-based helmets. The Department of Defense is continuing to invest in research to improve helmet performance, through better design and materials as well as better manufacturing processes. Review of the Department of Defense Test Protocols for Combat Helmets considers the technical issues relating to test protocols for military combat helmets. At the request of the DOD Director of Operational Test and Evaluation, this report evaluates the adequacy of the Advanced Combat Helmet test protocol for both first article testing and lot acceptance testing, including its use of the metrics of probability of no penetration and the upper tolerance limit (used to evaluate backface deformation). The report evaluates appropriate use of statistical techniques in gathering data; adequacy of current helmet testing procedures; procedures for the conduct of additional analysis of penetration and backface deformation data; and scope of characterization testing relative to the benefit of the information obtained.

Indonesia, the governing department should have standard rules into the production of the combat helmet for the army and how manufacturing processes should consider on the material and the design shape in the future, such as lowering weight and adding mobility to the user. Ultimately, the suggestions made in this report can plausibly change on how the governing standards of Indonesian combat helmets for the army can move into the next level and finally can demonstrate a higher level of quality in many parts of the helmet design that has been examined and analysed with the support of academic research and testing protocols. Currently, the department needs to focus on the potential fragmentation in the future such as threats, especially brain injury from bullet effects or other ballistic threats. As a result, it is arguable that the army and the head office of production for combat helmets should concern on the operational testing and evaluation before making the decision to produce the proposed design of the helmet. This can, therefore, improve the design of the combat helmet for the army in Indonesia.
