What document can be used to obtain basic information about a substance's chemical makeup, potential hazards, and safe handling data?

The Material Safety Data Sheet (MSDS)—now more commonly referred to as the Safety Data Sheet (SDS)—serves as a comprehensive resource that provides essential information about a chemical substance. This document outlines the chemical's properties, potential hazards, handling instructions, and emergency measures in the event of an incident. It is a crucial tool for ensuring safety in the workplace and during transportation, as it informs users of necessary precautions and the appropriate personal protective equipment needed when working with the substance.

Additionally, the SDS serves as a regulatory requirement in many jurisdictions, ensuring that all parties handling hazardous materials are well-informed about the risks associated with those substances and the procedures for safe use. This makes it an indispensable document for firefighters and other emergency responders to access critical information during a hazardous materials incident.
