NFPA 704 is designed for first responders with color-coded hazard rating.

• A. HMIS
• B. CANUTEC
• C. NFPA 704
• D. SETIQ

Answer: (C)

NFPA 704 provides a quick, at-a-glance way for first responders to gauge hazards at a scene. The color-coded diamond communicates three primary aspects—health (blue), flammability (red), and reactivity (yellow)—with a separate white area for special hazards. Each section uses a 0–4 scale, where higher numbers signal greater risk, guiding decisions about containment, isolation, ventilation, and protective measures. This system is specifically designed for emergency situations and on-container labeling to convey essential danger information fast. While HMIS is a workplace labeling system with similar ideas, it targets occupational safety and includes PPE information in a different format; CANUTEC covers transportation emergency guidance, and SETIQ is not the standard used here.
