What information does the red quadrant of the NFPA 704 indicate?

• A. Instability ratings from minimal to severe
• B. Health hazard ratings from low to high
• C. Flammability hazard ratings from non-flammable to very flammable
• D. Special hazard identification information

Answer: (C)

The red quadrant of the NFPA 704 label specifically indicates flammability hazard ratings, which assess how easily a material can ignite and sustain combustion. This quadrant uses a numerical scale from 0 to 4, where a rating of 0 signifies that a substance is non-flammable, while a rating of 4 indicates that it is highly flammable. This visual classification is essential for first responders and emergency personnel to quickly understand the potential fire hazards associated with a material in various situations, allowing for appropriate precautions to be taken during handling and response efforts.
