2. www.jst.umn.edu The science of designing and organizing equipment such that people use the equipment safely and efficiently, with the ultimate goal of minimizing risk factors for injury caused over time. Equipment = chairs, bench tops, storage containers, instrumentation, pipettes, etc. Ergonomics Teachworth, Erin. “Ergonomics At the Dow Chemical Company.” The Dow Chemical Company.

3. www.jst.umn.edu Ergonomics, General Rules Every 20 minutes, take a 20 second break Running a column  switch between standing and sitting Sitting at a desk typing  stand up and stretch Pipetting  switch hands Early detection of ergonomic injuries – If you have persistent pain (over one or two days), visit a doctor Teachworth, Erin. “Ergonomics At the Dow Chemical Company.” The Dow Chemical Company.

Add books or a box to adjust screen height 4. Use a foot rest, if necessary 2. Add a cushion for lower back support 1. Adjust seat height so that forearms are parallel to the ground

7. www.jst.umn.edu Lab Bench & Hood Ergonomics When standing – Wear comfortable (and safe!) shoes – Is anti-fatigue matting available? – Switch positions by propping foot up on a stool When seated – Work at a bench cut-out – Maintain proper posture – Do not over-reach 7

8. www.jst.umn.edu Lab Bench & Hood Ergonomics Avoid resting arms on hard surfaces or sharp edges Always take mini-breaks (20-30 seconds) every 20 minutes Rotate between tasks to work both efficiently and ergonomically 8

9. www.jst.umn.edu Lab Ergonomics Suggestions 1.Start with proper attire - Especially shoes! 2.Pay attention to posture - Can help avoid fatigue 3.Reduce back strain - Consider using a lab mat when standing for long periods 4.Embrace the mini break - Plan stretch breaks or change tasks when your muscles get tired to avoid strain or making mistakes 9 Central Science webpage.
