Which labeling requirement applies when a pesticide product is corrosive or irritating?

• A. The label must include bilingual text only
• B. Warning words must appear on the label as per regulations established since 1999
• C. The label must include a detailed chemical synthesis
• D. The label must include the active ingredient name only

Answer: (B)

When a pesticide is corrosive or irritating, the label must clearly communicate the hazard to anyone handling the product. Since 1999, Canadian labeling rules require standardized warning words on the label that reflect the product’s hazard class, along with the related precautionary statements and pictograms. This ensures consistent and immediate recognition of the danger and the precautions needed. The idea of a label that is only bilingual misses the core safety communication, while a detailed chemical synthesis or listing only the active ingredient name fails to convey the actual risks and how to use the product safely. Hence, warning words that match the hazard classification must appear on the label.
