CPA - Certified Pesticide Applicator Pesticide Label Comprehension Questions and Answers 1 — Questions and Answers
Question 1: A pesticide label features the signal word 'DANGER' along with a skull and crossbones symbol. What does this combination indicate about the product's toxicity?
- It is moderately toxic and can cause temporary skin irritation.
- It is slightly toxic but poses a significant environmental hazard.
- It is highly toxic by at least one route of exposure and may be fatal if ingested, inhaled, or absorbed through the skin. (Correct answer)
- It is corrosive and can cause irreversible eye damage, but has low systemic toxicity.
Correct answer: It is highly toxic by at least one route of exposure and may be fatal if ingested, inhaled, or absorbed through the skin.
The signal word 'DANGER' combined with a skull and crossbones and the word 'POISON' indicates the highest level of acute toxicity. This means the product is highly toxic and can be fatal if it enters the body through ingestion, inhalation, or skin contact.
Question 2: An applicator is planning to tank-mix two pesticides. Product A has a Restricted Entry Interval (REI) of 12 hours, and Product B has an REI of 48 hours. What is the legally required REI for the treated area after application?
- 12 hours, the shorter of the two REIs.
- An average of the two, which is 30 hours.
- Workers can choose which REI to follow based on their task.
- 48 hours, the longer of the two REIs. (Correct answer)
Correct answer: 48 hours, the longer of the two REIs.
When two or more pesticides with different Restricted Entry Intervals (REIs) are applied at the same time, the applicator must adhere to the longest REI. This ensures the highest level of protection for workers entering the treated area.
Question 3: Which of the following pieces of information is found in the 'Directions for Use' section of a pesticide label?
- The EPA Registration Number.
- First aid instructions in case of exposure.
- The target pests and application rates. (Correct answer)
- The signal word and child hazard warning.
Correct answer: The target pests and application rates.
The 'Directions for Use' section provides specific instructions on how to legally and effectively apply the pesticide. This includes the pests the product is registered to control, the sites it can be used on, application rates, and mixing instructions.
Question 4: A pesticide applicator needs to identify the facility where the pesticide product was manufactured. Which number on the label provides this specific information?
- The EPA Registration Number.
- The EPA Establishment Number. (Correct answer)
- The Active Ingredient CAS Number.
- The Manufacturer's Lot Number.
Correct answer: The EPA Establishment Number.
The EPA Establishment Number (EPA Est. No.) identifies the specific facility where the pesticide product was produced. The EPA Registration Number identifies the product itself and the company that registered it.
Question 5: A farmer applies a pesticide with a 24-hour Restricted Entry Interval (REI) to a field at 10:00 AM on Tuesday. According to the label, when is the earliest that workers can enter the field to perform hand-labor tasks?
- 4:00 PM on Tuesday, if wearing PPE.
- 10:00 PM on Tuesday.
- 10:00 AM on Wednesday. (Correct answer)
- Anytime on Wednesday.
Correct answer: 10:00 AM on Wednesday.
The Restricted Entry Interval (REI) begins immediately after the pesticide application is completed. A 24-hour REI means workers must not enter the treated area to perform hand-labor tasks for a full 24 hours. Therefore, they can enter at 10:00 AM on Wednesday.
Question 6: The phrase 'It is a violation of Federal law to use this product in a manner inconsistent with its labeling' is found on every pesticide label. This statement signifies that the label is a:
- Set of recommendations from the manufacturer.
- Legally enforceable document. (Correct answer)
- Guideline that can be modified by a certified applicator.
- Marketing tool with no legal standing.
Correct answer: Legally enforceable document.
This statement confirms that the pesticide label is a legal document. Using a pesticide in any way that contradicts the label's directions—including application sites, rates, methods, and safety precautions—is a violation of federal law.
