  2. What Is An Occupational Illness? Any work-related illness mainly caused or aggravated by exposure to Health hazards at work environment. It must arise out of or in the course of employment. As a result of R.exp/Time

  3. Health hazards • Physical e.g. Noise, heat, cold, radiation, vibration • Chemical e.g. asbestos, gases, vapours, lead • Biological e.g bacteria, viruses etc • Ergonimical-work station design- RSI • Psychological- Stress

  4. When an illness is work related? • Steps before diagnosis 1st step • Occupational History - Job description & tasks -Is causal agents/conditions present at work? -Was employee exposed? - List of previous employment & exposures -Is exposure sufficient to cause illness? - Duration and frequency of exposure

  5. - Is there any non-occupational exposure? -Family history- genetic - Past medical history - Second job and hobbies

  6. 2nd step • Clinical examination 3rd step • Investigations -Biological tests -Radiological - Physiological

  7. Has an illness indeed occurred? • Is the illness work-related i.e. attributable mainly to occupational exposure? 4th step • Site visit and exposure monitoring. Combination of steps from 1-4 would help you to make decision.

  8. Classification of Occupational Illnesses • Infectious and Parasitic Diseases • Skin Diseases and Disorders: 3. Respiratory Conditions due to Dust or Toxic Agents 4. Poisoning (Systemic Effects of Toxic Materials) 5. Upper limbs and neck disorders 6. Back problems and lower limbs disorders • Cancers and Malignant Blood Diseases • Diseases due to mental stress • Noise Induced Hearing Loss • Other Illnesses and Disorders

  9. Infectious and Parasitic Diseases Malaria, food poisoning, infectious hepatitis, legionnaire's disease • Skin Diseases and Disorders Contact dermatitis, allergic dermatitis, rash caused by primary irritants and sensitizers or poisonous plants, chrome ulcers • Respiratory Conditions due to Dust or Toxic Agents Silicosis, Asbestosis, pneumoconiosis, allergic asthma, allergic rhinitis due to chemicals, dusts, gases, or fumes. • Poisoning (Systemic Effects of Toxic Materials) Poisoning by metals e.g lead, mercury, arsenic, or other metals Poisoning by gas e.g carbon monoxide, hydrogen sulphide, or other gases Poisoning by solvents Poisoning by pesticides Poisoning by other chemicals such as formaldehyde, plastics and resins. 5. Upper limb and neck disorders e.g Mouse disease

  10. 6.Back problems and lower limbs disorder • Cancers and Malignant Blood DiseasesMesothelioma; bladder cancer; leukemia • Disorders due to Mental Stress Tension headache, depression. 9. Noise Induced Hearing Loss 10. Other Illnesses and Disorders Eye conditions due to dust and toxic agents e.g arc eye Heat problems and radiation.

  11. Who should report OH illness • Employee • Line manager/supervisor • Medical

  12. Why to report • Intervention/ corrective actions • Morals • Legislation • Litigation potential • Research and epidemiology • Costs (sickness absence etc) • Reputation

  13. Benefits of occupational illness early reporting • Early detection and intervention Prevention • Gain financially through-Reduced costs e.g insurance premium , reduced compensation, reduced absenteeism due to sickness • High moral  Increased productivity • Excellent reputation, increased public image- more competitive in the market • Prevents premature incapacity for work, reduces early retirement pension costs

  14. Disadvantages of ignoring and not reporting Be aware of the hidden costs of OI • Costs to train a new worker, • Repair damaged property • Investigate the accident and implement corrective action • Maintain insurance coverage(High premium) • Costs related to schedule delays and poorer customer relations • More staff falling sick and increased absenteeism • lower morale and high staff turn over

  15. Do we need to investigate occupational illness Y/N • Rule out/confirm WR • Identify root causes • Assess effectiveness of existing controls • Remedial actions

  16. How to prevent OI & your role Controls • HRA-identify hazards, assess and put controls(Engineering controls, admin controls, PPE) • Education and training • Health care facilities • Medicals check • Monitoring of health hazards in the work environment • Encourage early reporting

  17. Recommendations • Raise health awareness • Encourage reporting • Investigate all cases • Report to local authorities

  18. Occupational injury • Work injury is a case which results from a work incident or from exposure involving a single event. Single-incident concept! • Can be external or/and internal • Examples - Cut, amputation, laceration, bruise - Fractures - Strains and sprains - Back disorders due to instantaneous event e.g from slips, trips, sudden movements.

  19. -Deafness from explosion - Animal and insects bites except venomous - Burns- contact with hot or cold surfaces, chemical burns or electric burns.
