text: **Research on effective technical and organisational preventive measures**
  
  Based on these predominantly ‘diagnostical findings’, an often separated strain is the development of 
  preventive measures. Engineering and natural sciences mainly deal with the development of**preventive**
  **technical measures**to avoid accidents and limit health-impairing impacts. This technical OSH research 
  includes the development or improvement of preventive technologies, of safe and healthy products and 
  processes at workplaces, a regulation, a practical guidance or standard setting. 
  
  Social sciences (organisational sociology, occupational psychology and similar) are active in developing 
  **preventive measures for organisational risk factors**. They develop**best practice models and**
  **contribute to**guidance and standards, as well as background data and evidence for legislation 
  regulations and good practices of awareness raising and intervention. 
  
  **OSH systems and infrastructures**
  
  The**preventive effectiveness**of OSH systems and infrastructures in enterprises and at state level is 
  another major research field. These studies often focus on qualitative assessment, for example, the 
  assessment of the**performance and effectiveness of such systems and infrastructures**(e.g. 
  DG EMPL, IALI474). They often cover not only enterprises (employers and workers) and the government 
  but also the wider OSH infrastructure, for example, professional associations and research institutes. 
  
  Research about prevention practices and processes in enterprises 475 covers**aspects like awareness**
  **raising, supporting and hindering factors to initiate preventive activities**,476 the impact of guidance 
  and instructions for workers, training and education of OSH professionals, including concrete regulations 
  of their functions and responsibilities in enterprises, their dependencies and relations to the 
  management and to workers, and the role of legislation and state-based systems for prevention in 
  enterprises, or the quality of risk reduction measures.
