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 hand positions. They will allow the worker to keep the elbows(肘)next to the body to prevent damage to the shoulder and arm.
好的工具设计对于防止过度使用造成伤害非常重要。设计良好的工具和设备不需要太多的力就可以操作，并防止别扭的手位。允许工人让肘部靠近身体，防止肩部和手臂受伤。
Overuse injuries can therefore be prevented or reduced if the employer provides, and workers use：
因此，如果雇主提供，工人使用的工具具有如下特点，可以避免或减少过度使用伤害：
●power tools rather than having to use muscle power
●电动工具，不必使用肌肉力量
●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
●工具带有特殊设计手柄，允许手腕保持挺直（见图1）。这意味着手和手腕保持在同一位置，轻松地悬挂在人的一侧

●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 awkward for someone with a very small hand．This is a particularly important consideration for women who may use tools originally designed for men．
●工具带有把手，可以用整只手舒适地握住。这意味着有多种尺寸可供选择——请记住，对于一只手很小的人来说，为一只手很大的人提供舒适牢固的握持的工具可能会很尴尬。对于可能使用最初为男性设计的工具的女性来说，这是一个特别重要的考虑因素。
●tools that do not press fingers(or flesh)between the handles, and whose handles do not have sharp edges or a small surface area．
●工具手柄之间不压手指（或肉），手柄没有锋利的边缘或较小的表面积。
