LIBRARY ERGONOMICS
LIBRARY ERGONOMICSPresented By: Frank Gonzales, CEES, CEAS1SO.WHY AM I HERE? IDENTIFY potentially harmful activities on the job.
MODIFY work practices to reduce injury.
ASSIST with ergonomic problems you face @ work.
ANSWER questions
SUPPLY you with ergo tools you can use indefinitely!

Ergonomics at Work - Reducing awkward liftingMini-pallet for hand truck3This is a simple and effective idea from a library to help with moving tote boxes full of books. Rather than having to lift boxes to stack them on the hand truck, they built these mini-pallets out of plywood and 1x1 risers. This allows the hand truck nose plate to slide easily under the stack of totes.Risk Factors for MSDsRepetitive 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
5Work ZonesThe 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
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
Bending/Kneeling
Contact Stress - Concrete floorUse a Stool
Back InjuriesWashington 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 weightDecrease size/capacity of containerSlides, gravity chutes, fork liftsReduce horizontal distance Reduce vertical distance (stool)Eliminate twisting (proper lifting)
Lifting Limit = 34 Weight Lifted = 44 Back InjuriesWith changesGet closer to shelfUse of stoolRaise yourselfEliminate twist
Risk is reducedLift is NOT hazardous
Lifting Limit = 50 Weight Lifted = 44
Shelving Books Hand Injuries
Grip is too widePressure on hand/wrist/forearm increasedPower grip..but fingers stretched too far
Increased injury riskKeep Palm Up & NeutralSupination versus Pronation
