All parts of the Safety Data Sheet (SDS) must include which of the following?

The Safety Data Sheet (SDS) is a critical component of chemical safety that provides detailed information about a hazardous substance. The correct answer highlights the essential elements that must be included in every SDS, which are composition, hazards, and first aid measures.

Composition refers to the chemical identity of the substance, outlining the ingredients that make up the product. This is crucial for understanding potential health effects and the chemical properties involved. Hazards provide information on the dangers associated with the substance, including physical, health, and environmental risks, which are vital for assessing the risk and implementing appropriate safety measures. First aid measures describe the necessary steps to take in case of exposure, ensuring that anyone handling the material knows how to respond effectively to emergencies.

Although the other options may be relevant to certain contexts, they are not universally required in all sections of the SDS. For instance, preparation date and storage instructions are important but are not mandated as critical components that must be present in every SDS. Similarly, usage instructions may be included but are not always essential within the standardized sections of an SDS. Therefore, the inclusion of composition, hazards, and first aid measures is fundamental for ensuring safety and compliance with regulations regarding hazardous materials.
