What is the purpose of the NFPA 704 marking system?

• A. A System For Identifying The Specific Hazards Of A Material
• B. A System For Labeling Storage Locations
• C. A Method For Labeling PPE Requirements
• D. A Framework For Incident Command Structure

Answer: (B)

NFPA 704 marking communicates the hazards of a material at a glance with a diamond-shaped placard that has four color-coded sections: blue for health hazards, red for flammability, yellow for reactivity, and white for special hazards. This setup gives responders and workers a quick, standardized snapshot of what they’re dealing with, so they can judge risk and decide on appropriate actions, such as how to approach, isolate, or protect themselves during an incident. It’s about identifying the specific hazards of the material itself, not about labeling where materials are stored, detailing PPE requirements, or outlining an incident command framework.
