Correct Response: D. Material Safety Data Sheets (MSDS) are the best source of information for properly storing and disposing of chemicals. MSDS documents are produced by the chemical manufacturer for each given chemical. They contain information about each chemical's characteristics, including known hazards and procedures for proper storage and disposal. A reference guide of physics and chemistry data and formulas (A) may or may not include some of this information, but the MSDS would definitely have the information by design. A laboratory manual for introductory physics (B) would probably not contain this information, and it may or may not refer the reader to the pertinent MSDS for a given lab, as applicable. The National Science Teachers Association (NSTA) (C) does publish general information on classroom safety, including chemical safety, but the MSDS for any given chemical is specifically designed to contain the detailed information on that chemical, including proper storage and disposal.
