The most important things to include on an MSDS are the…

• A. The general storage requirements of the product
• B. Emergency contact times only
• C. Specific hazards, personal protection requirements, handling procedures, first-aid information, and the emergency response telephone number
• D. The shipping and packaging dimensions

Answer: (C)

Understanding what an MSDS (now called a Safety Data Sheet) communicates to workers is about equipping people with the information needed to work with a chemical safely. The most important content focuses on the hazards posed by the product and the concrete steps to protect yourself. That means clearly listing the specific hazards, what personal protective equipment and other safeguards are required, how to handle and store the material properly, what to do if exposure or a spill occurs (first-aid information), and the emergency response telephone number to call for immediate guidance or help.

This combination is essential because it directly informs safe work practices and emergency actions. Without knowing the hazards or the protective measures, workers can’t reliably prevent injuries. Without first-aid guidance, a mishap can escalate before help arrives. Without a readily accessible emergency contact, coordination and rapid response in crises are delayed.

General storage details or just emergency contact times miss critical pieces of safety information. Shipping and packaging dimensions are about logistics and not about the hazards, handling, or medical guidance a worker needs.
