Which one of the following provides a profile of hazardous substances or mixtures?

The Material Safety Data Sheet (MSDS) serves as a critical resource in providing detailed information on hazardous substances or mixtures. It contains essential data such as chemical characteristics, health and physical hazards, handling and storage recommendations, emergency procedures, and regulatory information. This document is designed to ensure that workers handling these materials have access to the necessary information to maintain safety and comply with regulations.

In contrast, while OSHA sets safety standards and regulations to protect workers, it does not specifically provide profiles on hazardous substances; rather, it oversees the enforcement of safety protocols. The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) focuses more on the cleanup of hazardous waste sites and the liability related to the release of hazardous substances into the environment rather than detailing their profiles. The Code of Federal Regulations (CFR) is a compilation of federal regulations but does not provide the specific, detailed safety profiles that the MSDS offers. This makes the MSDS the appropriate choice when seeking comprehensive profiles of hazardous materials.
