What does MSDS stand for?

The correct answer is "Material Safety Data Sheet." This term refers to a document that provides comprehensive information about a specific chemical substance or mixture. The MSDS includes details regarding the hazards, handling, storage, and emergency procedures related to that material, ensuring safety for those who may come into contact with it.

The MSDS is a critical resource in workplaces where hazardous chemicals are used, helping to inform employees about the risks and necessary precautions to take. This is essential for compliance with various regulations that govern workplace safety and environmental protection.

The other options do not accurately reflect the established terminology used in chemical safety. For example, "Main Safety Data Sheet" and "Materials Safety Distribution Sheet" do not correspond with standard industry terms, while "Mass Safety Data Standards" deviates from the established acronym and meaning as well. Understanding the correct term is vital for effective communication and safety in handling hazardous substances.
