text: **Work accidents**are probably the**most widely used indicator**for assessment of the effectiveness of 
  the OSH systems and the working conditions in general, also in a broader public; thus, this report will 
  tackle this topic more extensively than other topics. Work accidents are regarded as a result of 
  **insufficient safety prevention**.**Occupational and work-related diseases**are regarded as**short- or**
  **long-term outcomes**of all disease-generating circumstances or exposures at work, caused by any 
  type of material or substance, by unhealthy physical activity or unhealthy inactivity, or by disease- 
  causing aspects of human interaction at work. Occupational and work-related diseases are categorised 
  and assessed by experts, particularly by medical professions.**Wellbeing**is the newest concept, 
  covering the individual or group perception of the working conditions. 
  
  The**presence of risk factors**and — if possible — the**level of exposure**makes up the largest block 
  of datasets in the OSH Barometer that is used to assess working conditions.
