High force occurs in any tasks that: a worker describes as very demanding physically a worker needs help to do because of the effort it requires require a stronger person or two persons to do the task. Examples of high force include: Lifting, lowering or carrying a heavy object Lifting, lowering or carrying an object that cannot be positioned close to the body pushing or pulling an object that is hard to move or stop restraining a person or animal.(Figure 3) Figure 3 Examples of high using the hands and fingers include: using a finger-grip, a pinch-grip or an open-handed grip to handle a heavy or large load operating hand tools with tight squeeze grips(Figure 4) gripping small instruments with high force, for example, a dental hygienist cleaning teeth.
