谈谈HAVS（手-臂振动综合症）

Whenever you use hand-held powered work equipment, vibration can affect your hands and arms.

无论何时，只要使用手持式电动工作设备时，振动难免会对我们的手部和臂部产生影响。

Prolonged exposure to vibration can cause permanent changes to nerves, blood vessels, muscles and joints. And can lead to hand arm vibration syndrome or HAVS (Hand-Arm Vibration Syndrome), which can be severely disabling.

长期暴露在振动中，会导致神经、血管、肌肉和关节发生永久性的变化，而且可能会导致手-臂振动综合症或简称HAVS（手-臂振动综合症），进而导致严重致残。

Early signs and symptoms of HAVS are tingling, numbness and weakness in your fingers. If you feel any of these things and if the symptoms persist, stop work, tell your supervisor about it, and get medical advice.

手-臂振动综合症的早期征兆和症状是手指的刺痛、麻木和无力。如果你感觉有前面所述的这些症状，而且症状持续存在的话，请停止工作，告诉你的主管，并去获得医疗建议。

You could be at risk of developing HAVS, if you regularly have to use vibrating equipment. And the longer and more often you use it, the greater the risk.

如果经常使用振动设备的话，你可能就有罹患手-臂振动综合症的风险。事实上，使用振动设备时间越长，频率越高，罹患手-臂振动综合症的风险就越大。

The same applies, if you're holding work pieces which vibrate while being processed by powered machinery. It's important to assess the risks before you start. A risk assessment should consider whether the job could be done differently without using vibrating tools and machines.

如果拿着那些在动力设备加工过程中振动的工件，罹患手-臂振动综合症的风险也是同样会如此。在开始工作之前，去评估风险这一点非常重要。风险评估，应该考虑是否可以以不同的方式去完成工作-不使用振动工具和设备。

If the task must use vibrating tools, you should make sure it's the right tool for the job and that it's been properly maintained and works efficiently. If possible, use low vibration tools.

如果工作必须使用振动工具的话，我们应该确保该工具是适合于这项工作，得到了适当的维护，而且工作效率不错。如果有可能的话，要使用低振动的工具。

Hand-Arm Vibration risk assessment should also assess how long equipment can be safely used for, and how often you should take a rest.

手-臂振动风险评估，还应评估设备可以安全使用多久，以及使用多久应该休息一下。

When doing the job, make sure you stay warm and dry if possible, particularly, your hands. Also, if you can, reduce the length of time you use a tool in one go by taking a break.

如果可能的话，做需要使用振动工具的工作时，一定要保持温暖和干燥，尤其是手部。另外，还可以通过休息来缩短一次性使用振动工具的时间。

Don’t force a tool or work piece more than you have to. And when you're finished, ensure tools are put away and stored properly.

不要强迫让工具或者工件超过你的能力范围。振动工具使用完毕后，要确保工具得以妥善存放。

Are you prepared?
