Ergonomics Matches “job to the worker” & “Product to the end user” Brett Young MSE 32 Khalifa Maskery MSE 31 Today’s Objectives • • • • • Awareness Recognise hazards at your workstation Conduct a basic workstation assessment Modify and/or implement controls Discuss rehabilitation & return to work H E M P 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 Studies Illness • Headache • Lower back pain • Stiff neck • Shoulder pain • Sore wrist • Sore Eyes % of workers 21 38 32 31 43 32 Age bracket: 35-50 for lower back discomfort Age bracket 20-30 already showing significant discomfort Risk Factors of MSD 1. Working Posture (Static, Awkward) 2. Repetition & duration 3. Work Area Design − Workstation setup, office equipment 4. Individual factors − Pre-existing injury − Age of workforce 5. Work Organisation − Working longer hours − Desk/Office bound Disc Pressure Standing or Correct Seated Posture Discs take correct shape when spine is in ‘double S’ form Seated with Poor Posture Discs are compressed when spine is in ‘C’ form Chair • Stable base (5 castors) • Adjustable Lumbar Support • Cloth pan and back • Curved edges • Adjustable pan ??? • Adjustable Height & Armrests 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 Screens • Distance from the User • Level of Monitor • Repeated Head Movement • Reflection / Glare • Contrast / Brightness • Dust Build up • Readability 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 Keyboard / Mouse Keyboard / Mouse Telephones and workstation equipment 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 Workers • • • • • Utilise the Self Assessment Tools Modify your behaviour Stretch/move every 45 minutes Seek medical advice if pain persists Speak to your supervisor 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 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
