Material Safety Data Sheets (MSDS) are information sheets that must be provided by the manufacturer for all hazardous products.

• A. Warranty Information
• B. Emergency Response Plan
• C. Material Safety Data Sheets (MSDS)
• D. Product Safety Label

Answer: (C)

Material Safety Data Sheets are the formal documents that manufacturers must provide for hazardous products to communicate detailed hazard information and safe handling practices. They give a comprehensive overview of the chemical, including its identity, the hazards it poses, first aid measures, firefighting guidance, what to do in case of a spill or release, how to handle and store it, recommended protective equipment, and exposure controls. This makes them the best choice because they are specifically designed to convey hazard information and practical safety steps straight from the manufacturer, helping workers protect themselves and respond correctly to incidents.

Warranty information deals with guarantees about product performance, not safety hazards. An emergency response plan outlines procedures for responding to incidents but isn’t the detailed hazard information provided by the MSDS. A product safety label provides quick warnings on the container, but it does not contain the full, structured safety information found in an MSDS. (Note: many places now use Safety Data Sheets, which serve the same purpose with updated terminology, but the function remains to inform about hazards and safe handling.)
