A Material Safety Data Sheet (MSDS) is specifically designed to provide detailed information about the properties of a chemical substance, including its hazards, handling procedures, and safety measures. The MSDS contains important sections that outline the chemical's identity, physical and chemical properties, health hazards, protective measures, and safety precautions for handling, storing, and disposing of the material. This information is crucial for ensuring the safety of workers and the environment when dealing with potentially hazardous materials, which is why the choice related to the description of chemicals and safety procedures is the correct answer.

In contrast, instructions for roof installation primarily focus on construction techniques and do not include safety or chemical information. While a list of roofing materials may detail the types of materials used in roofing projects, it lacks the specific safety information inherent in an MSDS. Lastly, while the environmental impact of roofing materials is an important consideration, it is not a primary focus of an MSDS, which is centered on chemical safety rather than environmental assessments.
