  1. LIBRARY ERGONOMICS Presented By: Frank Gonzales, CEES, CEAS

  2. SO….WHY AM I HERE? IDENTIFYpotentially harmful activities on the job. MODIFYwork practices to reduce injury. ASSISTwith ergonomic problems you face @ work. ANSWERquestions SUPPLYyou with ergo tools you can use indefinitely!

  3. Ergonomics at Work - Reducing awkward lifting Mini-pallet for hand truck

  4. Ergonomics at Work - Reducing low work Raise and tilt the work

  5. Risk Factors for MSD’s • Repetitive Motion (without adequate rest periods) • Force (sustained beyond minimum effort) • Awkward Postures (prolonged and/or static) • Contact Stress (compromised circulation) • Environmental (noise, temperature, vibration) • Vibration (neurovascular shutdown) • Physical and Emotional Stress

  6. Work Zones The location of frequently-used devices (keyboard, phone, and mouse) should remain within the repetitive access (primary work zone) Figure 3. Recommended zones for workplace components

  7. Scanning/Bar-coding • Avoid bending over • Use an appropriate chair • Pull boxes out slightly to decrease reach • Set boxes on thighs • Use technique that is comfortable for you but does not expose you to injury risks

  8. Bending/Kneeling Contact Stress - Concrete floor

  9. Use a Stool

  10. Back Injuries • Washington State Lifting Equation (Lift of 44 lb tray is a Hazard) • Lift from standing on ground to above shoulder holding 44 lbs (1 tray/box weight = 44lbs) • To reduce risk: • Decrease load weight • Decrease size/capacity of container • Slides, gravity chutes, fork lifts • Reduce horizontal distance • Reduce vertical distance (stool) • Eliminate twisting (proper lifting) Lifting Limit    = 34  Weight Lifted   = 44

  11. Back Injuries • With changes • Get closer to shelf • Use of stool • Raise yourself • Eliminate twist • Risk is reduced • Lift is NOT hazardous Lifting Limit    = 50 Weight Lifted   = 44

  12. Shelving Books – Hand Injuries • Grip is too wide • Pressure on hand/wrist/forearm increased • Power grip……..but fingers stretched too far • Increased injury risk

  13. Keep Palm Up & Neutral • Supination versus Pronation Better Bad Best
