运输公司的工人可能会接触化学品，例如在装卸化学品，或安装和开启转运管道时。在这些情况下，运输公司是否应被视为下游用户？

The workers of transport companies can be exposed to chemicals, for example while loading and unloading chemicals, or fitting and opening of transfer pipelines. Should transport companies be regarded as downstream users in these cases?

通过铁路、公路、内陆水运、海运或空运运输危险物质和混合物不受 REACH 法规的约束（参见第 2(1)(d) 条）。运输公司进行的运输活动（包括装卸）不属于 REACH 法规下的“用途”。运输公司工人进行的装卸操作受《危险货物运输法》的约束，因此不属于 REACH 法规的约束范围。相比之下，装卸前和卸货后的现场相关活动通常属于 REACH 法规下的“用途”，可能需要暴露场景和化学品安全评估。同样值得注意的是，仅在工业厂房内发生的物质和混合物的转移也受 REACH 法规的约束，即使这包括由外部公司进行的运输。

The carriage of hazardous substances and mixtures by rail, road, inland waterway, sea or air is exempted from the scope of the REACH Regulation (see Article 2(1)(d)). Transporting activities (including loading and unloading) by transport companies are not "uses" under REACH. The loading and unloading operations performed by the workers of the transport company are covered by the Carriage of Dangerous Goods legislation, and hence they are outside of the scope of the REACH Regulation. Compared to that, the site-related activities before loading and after unloading will often be "uses" under REACH, which may need an exposure scenario and a chemicals safety assessment. It is also important to note that the transfer of substances and mixtures occurring exclusively within an industrial plant is covered by REACH, even if this includes transportation carried out by an external company.
