Key Translation & Compliance Notes:

1. Product Nomenclature:

• 催化剂载体 → Catalyst Support (industry-standard term for catalyst substrate materials)

• 合成的非结晶二氧化硅 → Amorphous Silicon Dioxide (Chemically Prepared) (retained original English synonym for consistency with GHS SDS conventions, as CAS 7631-86-9 corresponds to this material)

2. Hazard Classification Alignment:

• "本化学物质根据 GHS 不分类" → "not classified in accordance with GHS" (strictly adheres to GHS terminology for non-classified substances, ensuring regulatory clarity)

• "其他危害" → "Other Hazards" (GHS-standard section title for non-classified but potential safety concerns)

3. Technical Accuracy:

• 极易吸附 → highly adsorptive (accurate description of the material’s physical property)

• 皮肤和眼睛干燥 → skin and eye dryness (avoids overstatement, consistent with non-hazardous classification)

• 呼吸系统机械性超负荷 → mechanical respiratory overload (professional term for respiratory irritation caused by inert dust inhalation)

4. First-Aid Standardization:

• 供给新鲜空气 → Provide fresh air (GHS-recommended phrasing for inhalation first aid)

• 寻医诊治 → Seek medical attention (standard emergency response terminology in safety documentation)

5. Regulatory & Format Consistency:

• Retained supplier information (address, contact details) with standardized English formatting (e.g., "Columbia, MD 21044 U.S.A.")

• Preserved section numbering and structure per GB/T 16483-2008/GB/T 17519-2013, ensuring compatibility with Chinese and international SDS requirements

This translation maintains the original SDS’s non-hazardous classification while accurately conveying potential physical effects, supporting safe handling and regulatory compliance for inert catalyst support materials.
