What type of hazards do Safety Data Sheets (SDS) primarily address?

Safety Data Sheets (SDS) primarily address chemical hazards. These documents are crucial in providing information about the properties of chemicals, including their potential hazards, handling and storage procedures, first aid measures, and emergency response information. The primary purpose of the SDS is to ensure that workers who use, transport, or handle hazardous chemicals are informed about the risks associated with those substances and know how to use them safely.

While biological, physical, and ergonomic hazards are important aspects of workplace safety, they are not the main focus of SDS. Biological hazards pertain to living organisms that can cause harm, physical hazards relate to environmental factors that can cause harm (like machinery or slips), and ergonomic hazards are linked to workplace design and tasks that could lead to injuries. Therefore, the emphasis of SDS on chemical hazards makes this option the correct answer.
