tative solutions. Some preventative measures that should be followed during pipetting were reported in 1995 in the Fisher Scientific Lab Reporter. The suggestions are as follows:

• Rotate the pipetting tasks among several people
• Take short micro pauses of a few seconds, when you cant take a longer break
• Use only the force necessary to operate the pipette
• Choose pipettors requiring the least pressure
• Work with arms close to the body to reduce the strain on shoulders
• Keep hands and shoulders in a neutral position
• Use adjustable chairs or stools with built in solid foot stools
• Dont elevate your arm, without support, for lengthy periods of time
• Use shorter pipettes. This decreases the arm and hand elevation and consequent awkward positions
• Use low profile waste receptacles, no higher than the height of the tubes that you are using

Other articles have been written that detail even more suggestions that should be followed (Haskell, 1998), which include:

• Use electronic pipettes, which are programmable and reduce the need for excessive thumb force and repetition
• Choose a pipette that fits the hand. The hand should cover more than half, but not the entire, circumference of the pipette

Many of the suggestions that have been made over the course of the past few years focus on the fact that routine pipetting tasks should be spread out over the entire day and shared by all laboratory technicians. This, of course, is the first line of defense to preventing repetitive stress injuries. The second line of defense is the way the pipetting task is ac
