Which of the following best describes the purpose of the NFPA 704 placard?

• A. Identify hazards of materials for emergency response
• B. Indicate structural integrity
• C. Rate energy efficiency of the facility
• D. Determine occupancy classification

Answer: (A)

NFPA 704 placards are designed to communicate the hazards of a material at a glance to emergency responders so they can choose proper protective equipment, tactics, and evacuation needs during an incident. The placard uses color-coded sections and numeric ratings to convey health hazards, flammability, and reactivity, plus any special hazards in the white section. This quick snapshot helps responders assess risk and plan actions such as isolating the area, selecting appropriate extinguishing methods, protecting exposures, and monitoring for toxic releases. It isn’t about structural integrity, energy efficiency, or occupancy classification, which are addressed by other codes and systems.
