The NFPA 704 marking communicates information about what aspect of a material?

• A. To Classify Responders By Role
• B. To Label Storage Containers By Manufacturer
• C. To Communicate The Specific Hazards Of A Material
• D. To Measure Temperature Of A Hazardous Material

Answer: (C)

NFPA 704 marks are all about the hazards of a material and guiding responders on how to handle them. The diamond is divided into four colored sections: blue for health hazards, red for flammability, yellow for reactivity, and white for special hazards. Each section uses a 0–4 scale to show how severe the hazard is, with higher numbers indicating greater danger. The white area flags any special considerations (like oxidizers or specific PPE requirements). This system is designed so responders can quickly assess the risk and choose appropriate actions, not to identify the manufacturer, measure temperature, or assign roles.
