The article refers to the development project implemented since 2012 by scientific consortium led by the Instituteof Security Technologies “Moratex” from Lodz. The consortium also includes: Police Academy in Szczytno, Central Institute forLabour Protection in Warsaw, Protective Equipment Company “Maskpol SA” in Konieczki, Military Institute of ArmamentTechnology from Zielonka, Academy of Military Technical in Warsaw. The aim of the project is to develop a prototype of heavybullet-and fragment-proof vest with high ballistic resistance, as well as resistant to adverse environmental factors and with comfortof use. The authors discuss problems related to the use of currently applied personal protective equipment in the form of bodyarmor, identify user needs in this area, present proposals for solutions worked out by scientific and industrial consortium. In thisarticle are described the requirements for a heavy bullet-and fragment-proof vest, the anticipated results of the project, scheduledtasks to be implemented under the project, as well as a partial result of the work ordered to be done by a team of Police Academyin Szczytno. There are discussed in detail: Risk Analysis for heavy bullet-and fragment-proof vest, validation procedures for heavybullet-and fragment-proof vest and the process of validation and testing the prototype of this vest in operating conditions.
