What does MSDS stand for?

• A. Material Safety Data Sheet
• B. Master Safety Data Sheet
• C. Material Safety Description Sheet
• D. Material Safety Data Summary

Answer: (A)

MSDS is the historical term for the document that conveys essential safety information about a chemical. It stands for Material Safety Data Sheet, which is why this expansion is the correct one. The sheet covers what the chemical is, the hazards it poses, ingredients, first aid measures, safe handling and storage, required protective equipment, and steps for spills or emergencies. The other phrases—Master Safety Data Sheet, Material Safety Description Sheet, and Material Safety Data Summary—aren’t standard names for this document. Modern practice often uses Safety Data Sheet (SDS) instead, but the expansion given here corresponds to Material Safety Data Sheet.
