Which color represents special hazards in the NFPA 704 system?

• A. Red
• B. Blue
• C. White
• D. Yellow

Answer: (C)

In the NFPA 704 system, which is used for identifying hazards associated with materials in emergency situations, the color that represents special hazards is white. This color is specifically designated for indicating special hazards that may not fall under the categories of health, flammability, and reactivity.

For example, the white section may include symbols or letters that denote materials possessing unique risks such as radiation hazards, acid hazards, or other specific dangers that responders must be aware of. Understanding the role of this color is crucial for first responders to assess the situation effectively and implement the correct safety measures when dealing with hazardous materials. The other colors in the system each represent different categories of hazards: red for flammability, blue for health hazards, and yellow for reactivity, which helps in quickly communicating the nature of hazards present.
