High Repetition can result in injury if the repetition exceeds the body's capacity. Typically, given time, employees accommodate to given levels of repetition. Problems arise when there are dramatic increases in repetition, so great that the body cannot accommodate. While it is important to reduce repetitions whenever possible, it is also important to listen to the body. Symptoms are a signal that you may be exceeding your limits.
Forces vary with equipment type, design, and state of repair.
Recognize that when applying force to an object, forces are transferred through your body. For example when activating a pipetter, forces are transferred to your finger or thumb. Forces transferred to your body are affected by not only the amount of force, but also the distance through which a force is applied. Choosing equipment that requires less force to activate and requires a shorter activation distance can reduce forces transferred to your body. Ensuring that equipment is in good working order helps reduce the overall forces to the body.
