Laboratory Ergonomics

Laboratory activities typically involve either highly repetitive movements (ex. pipetting) or prolonged static postures (ex. Using a microscope, cell counting), sometimes both. These types of activities pose ergonomic risk because there is little variety in the muscles being used and long task durations. There is also often limited storage space in laboratories, as table tops and workstations need to remain uncluttered, many frequently used items are stored on overhead shelves or cabinets. This typical laboratory environment results in awkward lift postures and frequent reaches. Pinch grips are also often used with tweezers, eye eyedroppers or small pipettes.

General recommendations to improve laboratory ergonomics:

Store heavy objects on shelves below shoulder height whenever possible
Use a stable footstool or stepladder to reach objects stored on high shelves
Avoid twisting while carrying an object. The load should be directly in front of the worker
Store frequently used materials on shelving units which are located between knuckle and chest height
Utilize rotating platforms/shelves to store material close to the worker, reducing unnecessary reaching
Increase the diameter or span of the tweezers to reduce grip force
Use anti-fatigue mats or foot rests for areas requiring prolonged standing
Use thin flexible gloves that fit properly
Use tools with padded handles or large-diameter handles to reduce required grip force
Shift weight frequently when standing for prolonged time, use a footrest to prop up one foot at a time
