何时必须向客户提供附有暴露场景的安全数据表？

When does a safety data sheet with annexed exposure scenario have to be provided to customers?

根据 REACH 法规第 14 条或第 37(4) 条的要求，在进行化学品安全评估后，若得出暴露场景 (ES)，则必须将其作为附件附于安全数据表 (SDS) 中，前提是该暴露场景与客户相关。根据第 31(9) 条的规定，供应商应在出现可能影响风险管理措施的新信息或新的危害信息时立即更新其 SDS。暴露场景即为此类新信息，通常情况下，一旦获得该信息，就需要立即更新 SDS。所有在过去 12 个月内已获得特定物质或混合物的客户，均须立即获得包含此次更新所附暴露场景的 SDS。此规定自 REACH 法规生效之日起适用，无论物质是否已注册。如果暴露场景中的信息不影响风险管理措施，且暴露场景中不包含新的危害信息，则 SDS 无需更新。

Where an Exposure Scenario (ES) is developed as a result of conducting a chemical safety assessment as required by Article 14 or 37(4) of the REACH Regulation, it must be annexed to the safety data sheet (SDS), provided it is relevant for the customer. According to Article 31(9) a supplier shall update his SDS without delay as soon as new information which may affect the risk management measures or new information on hazards becomes available. An ES is considered to be such new information, which normally triggers the need to update a SDS as soon as it becomes available. The SDS with annexed ES resulting from this update has to be provided without delay to all customers who have been supplied with the particular substance or mixture within the preceding 12 months. This provision applies since the entry into force of the REACH Regulation and irrespectively of whether the substances are registered or not. Where the information in an ES that becomes available does not affect the risk management measures and the ES contains no new information on hazards, the SDS does of course not have to be updated.
