All chemicals in the workplace must be ______ and have a ______ as required by OSHA.

• A. clearly labeled; MSDS
• B. properly stored; hazard label
• C. sealed; SDS
• D. color coded; safety plan

Answer: (A)

Having chemicals in the workplace labeled clearly and accompanied by hazard information is essential for safety. Clear labels let workers instantly see what the substance is, what hazards it poses, and what precautions to take during handling, storage, and use. This immediate information helps prevent accidents and guides proper actions in everyday work and in emergencies.

The material safety data sheet, historically known as the MSDS, provides detailed, authoritative information about the chemical—its composition, physical and health hazards, required protective measures, first aid steps, and spill or exposure procedures. Employers are required to keep these sheets accessible so workers can review them when needed. While the modern term is Safety Data Sheet, the underlying purpose remains the same: supplying comprehensive hazard information to complement the label.

So, the statement that all workplace chemicals must be clearly labeled and have an MSDS aligns with OSHA’s requirements for labeling and hazard information, with SDS being the current standard term in many regulations.
