What should be included in a safety data sheet (SDS) for chemicals used in maintenance?

A safety data sheet (SDS) is a crucial document that provides comprehensive information about a chemical substance or mixture. The correct option emphasizes that an SDS must include handling, hazard, and emergency response information. This is essential for ensuring the safety of employees who may come into contact with hazardous materials.

Handling information educates users on how to manage the chemical safely, including proper storage and usage procedures. Hazard information details the risks associated with the chemical, including toxicological effects or flammability, which helps individuals understand the potential dangers they may face. Emergency response information is vital in the event of an accident or exposure, providing specific actions to take, such as first aid measures and firefighting techniques.

The other options, while they may contain elements related to the information about the chemical, do not focus on integral components that are specifically required for safety and compliance purposes. For instance, having only the manufacturer's contact information or solely product appearance does not provide sufficient safety guidance for users handling potentially dangerous materials. Additionally, cost information is not relevant to safety and is typically not included in an SDS, as it pertains more to procurement rather than safe handling or hazard assessment.
