Which of these provides details on a chemical's composition and hazards?

The Safety Data Sheet (SDS) is the correct choice because it serves as a comprehensive document that outlines essential information regarding a chemical's properties, composition, hazards, handling, storage, and emergency measures in case of exposure. This resource is critical for workers who handle hazardous materials as it provides guidance on proper handling techniques, personal protective equipment requirements, and first-aid measures. It ensures that employees have the necessary information to work safely with chemicals and to respond appropriately in the event of an incident involving those chemicals.

Other options, while they may contain valuable information, do not provide the same detailed and specific guidance as an SDS. A chemical information list might summarize various chemicals but lacks the in-depth hazard communication found in an SDS. An inventory log typically tracks what chemicals are on-site but does not elaborate on their risks or safety measures. An employee handbook could include safety policies and practices but is not designed to give detailed chemical hazard information.
