associated with pipetting include:
- Repetitive motion of the hands,
forearm and thumb, or fingers.
- Pinch grip when handling pipette

away from the body).
- Neck bent forward or to the side
and/or jutted chin.
- Awkward and static postures.
- Excessive force of the thumb.
- Standing for long periods of
eliminate/reduce the impact of
laboratory ergonomic stressors.
- Perform your work
only at appropriate heights.
- Alter continuous
repetitive pipetting by performing
other tasks, or take frequent small
rest breaks every 20 minutes.
- Make sure to work
with wrists in neutral positions
- Adjust height and
position of sample holders, solution
container, waste receptacle to
prevent twisting and bending of
wrist, neck and rolled shoulders.
- Reduce shoulder
strain, avoid working with winged
- Use short pipettes,
shorter waste receptacles for used
tips, to reduce reaching.
- Use electronic
pipettes for highly repetitive
pipetting tasks to reduce/eliminate
contact pressure on thumb
- Ensure proper lower
back and thigh support, use
adjustable stools or chairs with
built-in foot and armrest.
- Avoid standing for
long periods. If standing is
unavoidable, use Anti-Fatigue Mats.
- Work at appropriate
heights to minimize twisting of the
neck and torso.
- Replace manually
operated pipettes with electronic
ones for larger workloads
- Make sure head and
shoulders are kept in neutral
- Avoid elevating arms
and elbows above shoulder for
lengthy periods to prevent static
work of arm, and shoulder strain.
- Task sharing is
another way to reduce the impact of
