A MSDS provides information on material handling, toxicity and first aid.

• A. Emergency response procedures
• B. Material handling, toxicity and first aid
• C. Environmental impact assessments
• D. Chemical synthesis instructions

Answer: (B)

Material Safety Data Sheets focus on safety information for chemical products so workers can handle them without harm. The main idea here is that an MSDS provides guidance on how to handle the material safely, describes the health hazards it may pose (toxicity), and lists what to do if exposure or contact occurs (first aid). These elements help prevent injuries—knowing the proper handling procedures reduces risk, understanding toxicity informs precautions, and knowing first aid steps prepares you to respond quickly if something goes wrong. MSDSs do include other topics too, like spill response and storage, but the combination of handling guidance, toxicity information, and first aid actions is exactly what this document is designed to convey. The other options describe things outside the safety-focused purpose of an MSDS.
