15. Environmental Exposure and Injuries -Organic Solvents -Noise -Lighting -Climate -Heavy Physical Load Transport Injuries within the Work Sector must be Noticed!

16. 4. Public Area (School, Public facilities, Institutions) About 10% of All Injuries -School is more Dangerous to Children than Work to Grown-ups -7-9 Years: 1/3 of All Injuries;10-15 Years: ½ of All Injuries (Grown-ups: 1/3 are Work-related) -Physical Education is 3 Times More Risky than Other Lessons.

20. 8. Sea, Lake & River 1-3% of All Injuries -Has decreased the last 100 Years -Mostly Due to less Exposure -The Number of Accidents are Halved the Same Time as the Number of Boats has been Doubled -6 out of 10 Deceased were Under Influence of Alcohol -½ were doing Sports-Fishing -Bigger Boats show fewer Mortal Injuries

21. B. Social Environment Examples: -Different Schools -Pupils Mix -Ethnicity -School Bussing -Long School Hours -Alternative Pedagogic Programs -Psycho-Social Load -Urbanization -Unemployment -Work Organization, Stress, Monotony, Stimulation, Demand/ Control, Decision Making, Shift Work

22. C. Habits of Life 1. Tobacco 2. Alcohol -All Injuries: 1/3 Males, 1/6 Females -High: Single Accidents in Traffic, Drownings, Falls, Snow-Mobiles -1/5 of All Emergencies at Hospitals -More when Injury Diagnosis 3. Diet 4. Physical Activity -Regular Warming up -Experience

23. D. "Individual"Risk Factors(1) 1. Age and Gender -Children, esp. Boys are Over-Represented -Older Women are Over-Represented -Younger Men and Motor Vehicles -Women and Falls -All Road Users Accidents are Dominated by Males, Motor Bike and Moped Related Accidents Strikes Males to 90 % -Males over 40 Years of Age dominates Boat Accidents

24. D. "Individual"Risk Factors(2) 2. Genetics -Accident Proneness - Does it Exist? 3. Bodily Constitution 4. Previous Diseases or Injuries
