What is the purpose of the NFPA 704 system?

• A. To indicate hazard levels for emergency responders
• B. To designate electric operating areas
• C. To classify chemical compatibility
• D. To rate mechanical integrity of tanks

Answer: (A)

NFPA 704 provides a quick, standardized way to communicate hazards to emergency responders. The Fire Diamond uses color-coded sections to show health (blue), flammability (red), and reactivity (yellow), with numbers from 0 to 4 indicating the severity, plus a white section for special hazards or handling instructions. This at-a-glance snapshot guides responders on what PPE to wear, how to approach the scene, what extinguishing methods to use, and what evacuation or isolation steps may be needed. It isn’t about electric operating zones, chemical compatibility, or the mechanical integrity of tanks, which are covered by other systems and assessments.
