  1. Ergonomics Matches “job to the worker” & “Product to the end user” Brett Young MSE 32 Khalifa Maskery MSE 31

  2. Today’s Objectives • Awareness • Recognise hazards at your workstation • Conduct a basic workstation assessment • Modify and/or implement controls • Discuss rehabilitation & return to work HEMP

  3. Potential Health affects of working with Display Screen Equipment • Musculoskeletal discomfort • upper limb, neck, lower back • Overuse illnesses • Soft tissue, tendons e.g. CTS • Temporary eye strain and headaches • Fatigue and stress • Epilepsy • Facial dermatitis • Electromagnetic radiation • Effects on pregnant women

  4. Studies Illness % of workers • Headache 21 • Lower back pain 38 • Stiff neck 32 • Shoulder pain 31 • Sore wrist 43 • Sore Eyes 32 Age bracket: 35-50 for lower back discomfort Age bracket 20-30 already showing significant discomfort

  5. Risk Factors of MSD • Working Posture (Static, Awkward) • Repetition & duration • Work Area Design • Workstation setup, office equipment • Individual factors • Pre-existing injury • Age of workforce • Work Organisation • Working longer hours • Desk/Office bound

  6. Disc Pressure Standing or Correct Seated Posture Seated with Poor Posture Discs are compressed when spine is in ‘C’ form Discs take correct shape when spine is in ‘double S’ form

  7. Chair • Stable base (5 castors) • Adjustable Lumbar Support • Cloth pan and back • Curved edges • Adjustable pan ??? • Adjustable Height & Armrests • Start with feet flat on floor • Other types – Swiss ball, kneel chair, sit stand

  8. Work Desk • Adjustable height (start at 72 cm) • Sufficiently large (600 mm depth) • Clean, low reflectance surface • Allows flexible arrangement of • screen, keyboard, documents, phone

  9. Screens • Distance from the User • Level of Monitor • Repeated Head Movement • Reflection / Glare • Contrast / Brightness • Dust Build up • Readability

  10. Keyboards / Mouse • Carpal tunnel Syndrome • Mouse injury • Carpal tunnel Syndrome (CTS) is a condition that effects the hand and wrist. • It results when the median nerve does not work properly due to inflammation of the median nerve

  11. Keyboard / Mouse

  12. Keyboard / Mouse

  13. Telephones and workstation equipment

  14. Managers/Supervisors • Only purchase/supply approved office equipment • Ensure each workers’ workstation is assessed by HSE Focal Point • Consult/Listen to workers • Look for signs of problems • Find low-cost and no-cost solutions

  15. Workers • Utilise the Self Assessment Tools • Modify your behaviour • Stretch/move every 45 minutes • Seek medical advice if pain persists • Speak to your supervisor

  16. Rehabilitation & Return to Work • Remedial Actions • Assessment of Workstation • RSI Checklist • Medical Case Management • In-house medical staff • Work hardening • Job placement • Job redesign • Behavioural changes

  17. What are MSE doing? • Currently inspecting new facilities • Program to retrain HSE Focal Points • Workers to conduct self assessment tool • Target high risk workers/areas • Manage others for improvement • Program inspections & audits • Updating material on the Health webpage
