The construction and transport sectors are the industries with the highest proportions of workers exposed to vibrations in the European Union. Heavy equipment vehicle (HEV) drivers often perform operations on different uneven surfaces and are exposed to whole body vibration (WBV) on a daily basis. Recently, a new version of ISO 2631-5 was published. However, since this new method required as input the individual exposure profile and the acceleration signals recorded on more surfaces, limited studies have been carried out to evaluate HEV operations according to this standard. The objectives of this study were to assess the WBV exposure using the methods defined in ISO 2631-1:1997 and ISO 2631-5:2018 and to compare the obtained health risk assessments between drivers with different anthropometric characteristics. For this purpose, two drivers were selected and a field measurement campaign was conducted. Regarding short-term assessment, results showed that VDV was the most restrictive method with exposure levels above the exposure action limit value, while SdA indicated that the same exposures were safe for the worker. With respect to long-term assessment, Risk Factor R showed that the driver with the highest body mass index was the only one who exceeded the low probability limit of adverse health effects.
建筑和交通行业是欧盟中工人接触振动比例最高的行业。重型设备车辆 (HEV) 驾驶员经常在不同的不平坦表面上进行操作，并且每天都会受到全身振动 (WBV) 的影响。最近，发布了 ISO 2631-5 的新版本。然而，由于这种新方法需要输入个人暴露概况和在更多表面上记录的加速度信号，因此很少有研究根据该标准评估 HEV 操作。本研究的目的是使用 ISO 2631-1:1997 和 ISO 2631-5:2018 中定义的方法评估 WBV 暴露，并比较具有不同人体测量特征的驾驶员之间获得的健康风险评估。为此，选择了两名驾驶员并进行了现场测量活动。关于短期评估，结果表明 VDV 是最具限制性的方法，其暴露水平超过了暴露行动限值，而 SdA 则表明相同的暴露对工人是安全的。关于长期评估，风险因素 R 表明，体重指数最高的驾驶员是唯一超过不利健康影响低概率限制的驾驶员。
