Position number one on an NFPA 704 placard corresponds to which hazard?

Explanation:
Health hazards are indicated by the blue section at the top of the NFPA 704 placard. The blue area represents health risk, and the number inside it shows how severe that health hazard is (0 to 4, with higher numbers meaning greater risk). So position number one corresponds to Health hazards, shown in blue. The other colors indicate flammability (red), reactivity (yellow), and special information (white).
