Laboratory Ergonomics

    Click on the tabs below for suggestions, and use this laboratory ergonomics self-evaluation checklist (from Washington University) to help you arrange you lab spaces.

    • Take short breaks every 20 minutes to reduce joint strain and muscle fatigue.  Do this even if you are “comfortable” because it will help reduce the potential effects caused by repetitive motions, etc.
    • Keep frequently used items within close reach.  Most frequently used items should beat approximately a forearm’s reach away, with lesser-used items up to arm’s reach away.  Items you are currently working with should be directly in front of the body.
    • Maintain an upright posture. Adjust the position of your work, your work surface, and your chair to avoid leaning or hunching over, or having to stretch while reaching.
    • Work Surface Height.
      • For precision work, adjust (if possible) the work surface height or your chair to bring the work closer to you.
      • For regular light work, the work surface should be around elbow height or just below.
      • For heavy work, the work surface should be approximately six inches below elbow height.
    • Chair Posture.
      • When sitting, sit against the back of your chair.  If your feet come off the ground, lower the chair or use the foot ring.  Try to work at a bench cut or space with adequate knee clearance; you need room for your legs.
    • Arms & Torso.
      • Keep shoulders, arms and hands relaxed and elbows close to the sides while working; do not work with “winged” elbows.
      • Try to keep the wrists neutral (straight) and aligned while working.  Sitting/standing close to your work will help with this.
      • Avoid elevating arms and elbows above shoulder for lengthy periods to prevent static work of arm, and shoulder strain.
    • Make sure all equipment is clean and in good working order to help minimize forceful twisting, turning, and pinching.  Equipment should be the right size for your hand.  Use padding and/or tubing on equipment and work area edges to reduce pressure and force while working.
    • Use the lightest pressure possible to hold or operate your equipment (e.g. pipettes).  Use electronic, automated, or light touch model equipment when possible.
    • Remember to vary your tasks or take frequent short breaks (e.g., ≥ 2 minutes for every 20 minutes of pipetting).
    • Alternate your grip on items like forceps and pipetting if possible.
    • Intensive tasks should be spread through the day or shared between employees when possible.
    • Ensure proper lighting for your task.
    • Store heavy items on lower shelves.
    • Use bottle dispensers and bottom dispensing carboys for dispensing liquids.
