Which section of an SDS lists the first-aid measures for exposure?

The correct choice details the section of a Safety Data Sheet (SDS) that specifically addresses first-aid measures for various types of exposure to hazardous substances. Section 4 of an SDS is dedicated to "First-Aid Measures." This section provides essential information on the appropriate responses in case of exposure to the substance, including the necessary actions for different scenarios such as inhalation, skin contact, or ingestion. By specifying the first-aid measures, this section helps ensure that individuals can quickly and effectively respond to health emergencies, potentially minimizing adverse health effects.

In contrast, other sections of the SDS cover different topics; Section 1 typically outlines identification and hazard classification, Section 7 discusses handling and storage recommendations, while Section 10 deals with stability and reactivity of the substance. Each section serves its distinct purpose, contributing to overall safety but focusing on different aspects of handling hazardous materials.
