The pest control product number on Canadian pesticide labels is analogous to which US identifier?

• A. Environmental Protection Agency (EPA) registration number
• B. Poison control number
• C. Department of Transportation hazard class number
• D. United Nations identification number

Answer: (A)

Pesticide product identifiers on labels come from regulatory approval, confirming the product has been reviewed and authorized for sale. In Canada, this is the Pest Control Product Number issued by the Pest Management Regulatory Agency. The US equivalent is the EPA registration number, issued by the Environmental Protection Agency under FIFRA. This number shows the product has been evaluated for safety and efficacy and that its label directions are approved for use in the United States.

Poison control numbers are for medical guidance if someone is poisoned. DOT hazard class numbers relate to shipping and handling hazards, not product approval. UN identification numbers are used for labeling and transporting dangerous goods.
