What is the purpose of Safety Data Sheets (SDS) in chemical unit operations?

• A. To provide hazard information, handling instructions, first aid, and safety measures for materials used or stored.
• B. To determine the price of materials.
• C. To schedule deliveries.
• D. To train new recruits.

Answer: (D)

Safety Data Sheets provide the essential information you need to work with chemicals safely: they describe the hazards, how to handle and store the material, what to do in case of exposure or accidental release, and the protective measures and first-aid steps required. In chemical unit operations, consulting the SDS before using a chemical helps you understand the specific risks, select appropriate personal protective equipment, design proper ventilation and containment, and plan emergency responses. The SDS also covers safe disposal, transport considerations, and regulatory notes, making it the go-to reference for hazard communication and safe operation. While training and procedures can draw on SDS content, the primary purpose is to convey hazard information and safety measures, not to determine price, schedule deliveries, or serve as a training module on its own.
