Which system is the standard for identifying hazardous materials for emergency response?

• A. Globally Harmonized System (GHS)
• B. NFPA 704 system
• C. DOT hazard placards
• D. OSHA Hazard Communication Standard

Answer: (B)

NFPA 704 is the standard system used by emergency responders to quickly identify hazardous materials at a scene. It features the Fire Diamond, a colored square divided into four sections: blue for health hazards, red for flammability, yellow for reactivity, and white for special hazards. The numbers in the colored sections range from 0 to 4, indicating increasing severity, so responders can gauge risk at a glance and determine appropriate protective actions. The white section notes special hazards like oxidizers, acids, alkalis, or materials that react dangerously with water. This system is purpose-built for on-site crisis situations, enabling rapid assessment without needing to read lengthy text. Other options serve different purposes: GHS focuses on classification and labeling for general workplace safety and international consistency; DOT placards convey transportation hazards on vehicles and packages; OSHA Hazard Communication Standard governs worker-focused labeling and safety data sheets.
