LABORATORY GUIDELINES

Pipetting


SAFETY GUIDELINES FOR:

To Control Awkward Postures:

  • Work with wrists in straight, neutral positions.
  • Incline sample holder or solution flask to improve access.
  • Reduce reaching by:
    • Using short pipettes.
    • Using low profile waste receptacles for used tips.
    • Using low profile solution containers.
  • Keep items as close as possible.
  • Work with elbows as close to sides as possible.
  • Assure proper lower back and thigh support from chair. Support the feet.
  • Assure items are positioned to minimize twisting of the neck and torso.
To Control High Repetition:

  • Automate pipetting tasks.
  • Use multi-pipetters whenever practical.
  • Share workload between right and left sides.
  • Vary pipetter types having different activation motions (e.g. thumb controlled vs. finger controlled).
  • Take adequate breaks away from pipetting activity-even short several second "micro-breaks" help.
  • Rotate pipetting among several employees.
  • Evaluate work processes to spread pipetting throughout the day.
  • Add personnel for peak periods.

To Control Excessive Force:
  • Choose pipetters that require less finger or thumb motion to activate.
  • Use pipette tips that seal easily; avoid banging when applying tips.
  • Use tips designed for the pipette.
  • Use multi-channel pipettors when possible.
  • Choose pipetters that require less force to activate.
  • Use only the force necessary to activate.
To Control Contact Stresses:
  • Choose pipetters that best fit your hand.
  • Do not rest forearms on a sharp edge. Pad the edge or forearm, or create a forearm rest.
