Which statement about chemical safety documents is true?

• A. Available from the National Institutes of Health
• B. They are not required
• C. They are rarely useful
• D. The SDS and TDS supplied by the manufacturer are included

Answer: (D)

Chemical safety documents are provided by the product manufacturer and are essential for understanding hazards and safe use. The Safety Data Sheet explains the hazards, first aid measures, handling and storage, required PPE, and exposure controls, while the Technical Data Sheet offers product-specific technical information and recommended usage. These documents come with the product or are readily accessible from the manufacturer, so they’re included as part of the safety information you should rely on. That’s why the statement about the SDS and TDS supplied by the manufacturer being included is true. The other options miss how these documents are produced and required: NIH is not the general source for every chemical, these documents are required by regulations, and they’re indeed very useful for safe handling.
