Which symbol indicates moderate hazard?

• A. Skull and crossbones indicates poisonous
• B. Diamond symbol with 'warning' indicates moderate hazard
• C. Flame indicates flammable
• D. Octagon symbol indicates extreme hazard

Answer: (B)

Understanding hazard labeling on pesticide products: the level of hazard is communicated not just by the symbol, but also by the accompanying signal word. A diamond-shaped symbol with the word “warning” is used to indicate moderate hazard. This tells you there is some risk, but it’s not the highest level of danger, and appropriate precautions can manage it.

Other symbols point to different, typically more severe or different types of hazards. The skull and crossbones signifies toxicity and a higher level of acute danger. The flame marks flammability, indicating a fire hazard rather than a general moderate health hazard. An octagon symbol is associated with the most extreme level of hazard in this labeling system. So, the diamond with “warning” best represents a moderate hazard.
