Final answer:
The second main purpose of the MSDS is to provide safety and handling information for the chemical product, including safe usage, first-aid, and necessary precautions.
Step-by-step explanation:
The MSDS, or Material Safety Data Sheet, serves two primary purposes. The first is to provide product information, detailing the chemical properties, usage, and storage of a substance. The second purpose is to provide safety and handling information. This includes details on how to safely handle and store the chemical, first-aid measures, control measures, and the necessary personal protective equipment (PPE) to be used when dealing with the substance. Therefore, the correct answer to what the second main purpose of the MSDS provides is c) Safety and handling information.
