What is a primary source of information regarding the properties and hazards of specific chemicals?

The Safety Data Sheet (SDS) is a primary source of information that provides detailed information about the properties and hazards of specific chemicals. An SDS contains critical safety information, including physical and chemical properties, health hazard data, protective measures, and emergency response guidelines. This document is essential for anyone handling hazardous substances as it helps ensure safety in storage, usage, and disposal.

While other resources, such as National Fire Protection Association guidelines, local fire department manuals, or Environmental Protection Agency reports, may offer valuable information about hazards and regulatory guidance, they are not as specialized or comprehensive as the information found in an SDS. An SDS is specifically focused on a particular chemical's hazards and the appropriate safety measures, making it the go-to resource for understanding how to safely handle and respond to incidents involving hazardous materials.
