Which symbol is associated with danger in pesticide hazard labeling?

• A. Flame
• B. Skull and cross bones
• C. Biohazard
• D. Radioactive

Answer: (B)

Pesticide hazard labeling uses pictograms to quickly convey the type of danger. The skull and crossbones is the symbol for acute toxicity or poisoning, meaning exposure by swallowing, inhaling, or skin contact can cause severe illness or death. This is why it’s used to warn handlers to take strict precautions, wear appropriate PPE, and follow first-aid and storage instructions on the label. The flame pictogram indicates flammability, the biohazard pictogram signals biological hazards, and the radioactive pictogram signals radiological hazards—different categories, so they don’t convey poison risk the same way the skull and crossbones does.
