如何检查我的使用和使用条件是否在收到的暴露场景的范围内？

How to check if my use and the conditions of use are covered by the exposure scenario received?

检查纳米形态和非纳米形态的用途和使用条件的过程并无不同。请务必仔细检查适用于您的纳米形态的用途（如果安全数据表 (SDS) 涵盖了该物质的多种（纳米）形态）。下游用户指南第 4.2 节提供了有关如何进行检查（确定您的用途和使用条件是否包含在提供的暴露场景中）的详细信息。检查包括三个步骤：检查用途：将您的用途与 SDS 第 1.2 节和所附暴露场景标题部分中的“已识别用途”进行比较；检查暴露场景的流程/活动：将您的流程/活动与暴露场景中描述的流程/活动进行比较，以确保您使用该物质的方式已在供应商的评估中涵盖；检查使用条件：将您的现场操作条件和风险管理措施（包括其有效性）与暴露场景中描述的进行比较。如果您得出结论认为您的用途包含在收到的暴露场景中，则无需根据 REACH 采取进一步行动。尽管如此，您仍应记录您的检查以及您采取的任何行动，以确保您遵守暴露场景中的使用条件。

The process of checking the uses and conditions of use is not different for nanoforms and non-nanoforms. Be careful that you check the uses applicable to your nanoform (in case the safety data sheet (SDS) covers several (nano)forms of the substance). Details on how to perform the check (on whether your uses and conditions of use are covered by the provided exposure scenario) are provided in section 4.2 of the Guidance for downstream users. The check includes three steps: Checking the use(s): compare your use(s) with the “identified use(s)” in SDS Section 1.2 and the title section of the attached exposure scenarios; Checking processes/activities of the exposure scenario: compare your processes/activities with those described in the exposure scenario to ensure that the way you use the substance has been covered in the supplier’s assessment; Checking the conditions of use: compare your onsite operational conditions and risk management measures (including their effectiveness) with those described in the exposure scenario(s). If you conclude that your use is covered by the exposure scenario received, no further action under REACH is needed. You should nevertheless document your check and any action you take to guarantee your compliance with the conditions of use in the exposure scenario.
