What are the colors used in the NFPA label system?

• A. Green, yellow, blue, and red
• B. Blue (health hazard), red (flammability), yellow (reactivity), and white (specific hazards)
• C. Purple, orange, green, and red
• D. White, black, blue, and orange

Answer: (B)

The colors used in the NFPA (National Fire Protection Association) label system are specifically designed to indicate the severity of health hazards, flammability, reactivity, and any specific hazards associated with a material. In this system, blue represents health hazards, red signifies flammability, yellow denotes reactivity, and white is used for specific hazards. This coding system provides emergency responders crucial information at a glance, enabling them to assess danger levels quickly and make informed decisions when handling hazardous materials. The blue color, for instance, allows them to understand potential health risks, while the red color provides insights into how likely a substance is to ignite. The yellow alert indicates how reactive a material may be, and the white symbol indicates additional threats like radiation or acid properties. The other choices do not accurately represent the NFPA labeling system, which is why they are not correct. For instance, the inclusion of colors like green or purple in those options diverges from the established NFPA protocol.
