Laboratory Workbenches
When used inappropriately, laboratory workbenches can expose researchers to a variety of hazardous conditions or ergonomic risk factors depending on the laboratory procedure being used. Most workbenches at the University are of fixed heights and cannot be modified (raised or lowered). In general they are the same height and were designed for light to slightly heavy work. Using a laboratory workbench as a computer workstation is an example of inappropriate use, since it forces the worker to assume a variety of awkward postures and may increase the likelihood of acquiring MSD. Laboratory workbenches are at fixed heights and have been designed using general guidelines suggested by the National Institute of Occupational Safety and Health (NIOSH). These guidelines are as follows:
- Precision Work - Workbench height should be above elbow height.
- Light Work - Workbench height should be just below elbow height.
- Heavy Work - Workbench should be 4-6 inches below elbow height.
Preventive Measures:
- Use a fully adjustable ergo-task chair or stool with built-in solid footrest.
- Use anti-fatigue mats if you will be standing for long periods of time while working at the laboratory workbench.
- Remove drawers, supplies and other materials underneath workbenches to provide legroom.
- Use an ergonomically designed footrest if your feet do not rest comfortably on the floor.
