A. Real Exposure Index
,B. Restricted-Entry Interval
C. Required Environmental Inspection
D. Residual Effect Item
Answer: B. Restricted-Entry Interval
Rationale: The REI is the amount of time that must pass before people can enter a
treated area without protective clothing.
If a pesticide is spilled on your skin, what is the very first thing you should do?

What is "drift"?
A. The movement of pesticide through the soil
B. The movement of pesticide through the air to an unintended site
C. The breakdown of pesticide by sunlight
D. The mixing of two different pesticides
Answer: B. The movement of pesticide through the air to an unintended site
Rationale: Drift can occur as droplets or vapors and is a major cause of off-target
damage and litigation.
A "Restricted Use" pesticide (RUP) can be purchased by:
A. Any homeowner
, B. Only certified or licensed applicators
C. Anyone over the age of 18
D. Only government employees
Answer: B. Only certified or licensed applicators
Rationale: RUPs are not available to the general public because they require specific
training to use safely.
Which section of the label provides instructions on what to do if the product is
swallowed?
A. Environmental Hazards
B. Physical Hazards
C. Statement of Practical Treatment (First Aid)
D. Directions for Use
Answer: C. Statement of Practical Treatment (First Aid)
Rationale: This section provides immediate emergency medical instructions.
"Integrated Pest Management" (IPM) focuses on:
A. Using as much pesticide as possible to ensure control
B. Using a combination of tools to manage pests with the least risk
C. Only using biological control methods
