何时需要将补充危险说明 EUH029 -“与水接触释放有毒气体”分配给物质或混合物？

When is it relevant to allocate the supplemental hazard statement EUH029 - "Contact with water liberates toxic gas" - to a substance or mixture?

根据CLP附件二第1.2.1节的标准，该危险说明适用于“与水或潮湿空气接触后，释放出具有潜在危险量的急性毒性1、2或3类气体（例如磷化铝、五硫化二磷）的物质和混合物”。该说明未提供关于何时应指定此危险说明的进一步标准或指导，也没有指明适当的测试方法。建议将任何量的急性毒性1、2或3类气体排放到EUH029中。因此，建议将此语句添加到每种与水接触时释放有毒气体的物质或混合物中。

According to the criteria given in section 1.2.1 of Annex II to CLP, the hazard statement applies to 'substances and mixtures which in contact with water or damp air, evolve gases classified for acute toxicity in category 1, 2 or 3 in potentially dangerous amounts, such as aluminium phosphide, phosphorous pentasulphide.' No further criteria or guidance are provided as to when this hazard statement should be assigned and no appropriate test methods are indicated. It is recommended that any amount of acute toxic category 1, 2 or 3 gas emitted triggers the inclusion of EUH029. It is thus also recommended to add this sentence to each substance or mixture that releases a toxic gas when in contact with water.
