What document should always be reviewed before working with a new chemical?

The Safety Data Sheet (SDS) is the correct document to review before working with a new chemical because it provides crucial information about the chemical’s properties, hazards, handling and storage requirements, first aid measures, and emergency procedures. Each SDS contains standardized sections that outline the risks associated with the chemical, including its toxicity, flammability, reactivity, and safe usage protocols.

Understanding the details provided in an SDS is essential for maintaining a safe working environment, as it helps laboratory personnel to prepare for potential hazards and respond appropriately in case of an accident or exposure. This proactive approach to safety ensures that all team members are informed of the necessary precautions and procedures for handling the chemical effectively and safely.

While other documents like the Chemical Abstracts Service (CAS), inventory lists, or lab manuals can be useful for various purposes, they do not provide the comprehensive safety and hazard information needed for safe chemical handling that the SDS offers.
