  1. What shape is used for the NFPA 704 hazard identification system placard?

    Answer: Square rotated 45 degrees (diamond)

    NFPA 704 uses a square rotated 45 degrees, commonly called a 'fire diamond,' divided into four colored sections.

  2. How many sections does the NFPA 704 hazard diamond contain?

    Answer: 4

    The NFPA 704 diamond contains exactly 4 sections: blue (health), red (flammability), yellow (instability), and white (special hazards).

  3. In the NFPA 704 system, which color section represents the health hazard?

    Answer: Blue

    The blue section, located on the left side of the diamond, represents the health hazard rating.

  4. In the NFPA 704 system, which color section represents flammability?

    Answer: Red

    The red section, located at the top of the diamond, represents the flammability hazard rating.

  5. In the NFPA 704 system, which color section represents instability or reactivity?

    Answer: Yellow

    The yellow section, located on the right side of the diamond, represents the instability/reactivity hazard rating.

  6. What is the highest numerical hazard rating on the NFPA 704 scale?

    Answer: 4

    The NFPA 704 scale ranges from 0 (minimal hazard) to 4 (most severe hazard) for health, flammability, and instability categories.

  7. A rating of '0' in any NFPA 704 category indicates the material:

    Answer: Poses no significant hazard in that category

    A rating of 0 means the material poses no significant hazard in that particular category under fire conditions.
