Multiple Choice

Which HazMat color code represents health hazards (poisons)?

Explanation:
Blue indicates health hazards in the NFPA 704 hazard recognition system. This color signals potential harm to health from exposure, such as poisons or toxic effects, with numbers in the blue area (0–4) showing how severe the risk is. White covers special hazards, not general toxicity, so it wouldn’t be used to denote poisons. Green is not part of the NFPA 704 color scheme for health hazards, though some labeling contexts use green for non-flammable gas, which is a different system. Therefore, blue is the color used to represent health hazards.
