  1. Study on the Occupational Health RisksforCable Laying Works Presented by : Fung Wing Hon

  2. Cable Laying Works • Trench Excavation • Shoring • Cable Laying • Installation of rollers • Manual Pulling / Operation of winch • Cable jointing • Backfilling and Reinstatement

  3. Occupational Health Risks Environment Chemical Factors Psychological Factors Biological Factors Physical Factors Ergonomics Factors

  4. Tool for Evaluating OH Risks • Exposure Assessment Strategies (EAS) was developed by AIHA EAS Committee in 1991. • A comprehensive, systematic and efficient approach to assessing, analyzing and managing occupational health risks, including workplace chemical, physical, biological and ergonomic agents.

  5. Overview of EAS

  6. Exposure Rating A >=RV B >=50%, <100% RV C >=10%, <50% RV D >=1%, <10%RV E Nil Health Effect Rating I II III IV Exposure/Health Effect Analysis

  7. Exposure/Health Effect Analysis Intervention required eliminate/substitute hazards or control the exposure Maintenance and continuous improvement of existing control systems Maintenance of existing control systems

  8. Tools to Manage OH Risks • Elimination/Substitution/Control/PPE • Work System Compatibility Theory • Theory developed by Dr. Ash Genidy of the University of Cincinnati, Ohio, USA in 1993 • The higher the WSC, the better the outcome measures of human performance (fewer work accidents and injuries/illness, higher work satisfaction, higher work quality….

  9. WSC Model Physical Environment Conditions Social Environment Conditions Organizational Environment Conditions Task Demand Energy Replenishment Forces Non-physical Environment Conditions Job Standards Energy Expenditure Forces Output Vs Job Standards Feedback to Energy Replenishment Forces Feedback Output

  10. Work System Compatibility Theory General Craftsmanship Specialized Craftsmanship : Scientific Management Management Science Motion & Time Study Health and Safety Efforts Quality of Output Movement Work Satisfaction Quality of Work life Work System Compatibility Theory
