Position number three corresponds to which hazard?

Position number three corresponds to which hazard?

• A. Reactivity (yellow)
• B. Health (blue)
• C. Flammability (red)
• D. Special information (white)

Answer: (A)

The thing being tested is how to read the NFPA 704 hazard diamond and map positions to hazard types. In this system, the colored quadrants correspond to different hazards: blue for health, red for flammability, yellow for reactivity, and white for special information. The numbers in each quadrant indicate how severe that hazard is, from 0 to 4. When you’re told that position three is being referenced, that points to the yellow quadrant, which represents reactivity. So the hazard associated with that position is reactivity. Reactivity describes how likely a material is to undergo a chemical change under normal conditions, potentially becoming unstable, reacting violently, or releasing energy under certain stimuli or in contact with incompatible materials.
