Good tool design is important in the prevention of overuse injuries. Well-designed tools and equipment will require less force to operate them and prevent awkward(别扭的)hand positions. They will allow the worker to keep the elbows(肘)next to the body to prevent damage to the shoulder and arm.
Overuse injuries can therefore be prevented or reduced if the employer provides, and workers use:
●power tools rather than having to use muscle power
●tools with specially designed handles that allow the wrist to keep straight (See figure 1). This means that hands and wrists are kept in the same position as they would be if they were hanging relaxed at a person’s side
Figure1. Bend the tool, not the wrist
●tools with handles that can be held comfortably by the whole hand. This means having a selection of sizes-remember that tools that provide a comfortable firm hold for a person with a very large hand may be of no use for someone with a very small hand. This is a particularly important consideration for women who may use tools originally designed for men.
●tools that do not press fingers (or flesh) between the handles, and whose handles do not have sharp edges or a small surface area.
