1. Which federal law primarily regulates the registration, labeling, and
use of fumigant pesticides in the United States?
A. Clean Air Act
B. Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
C. Occupational Safety and Health Act
D. Food Safety Modernization Act
Answer: B. Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
FIFRA regulates pesticide registration, labeling requirements, and lawful
use, including fumigants used for pest control applications.
2. The main purpose of a fumigant pesticide is to:
,A. Create a toxic gas that penetrates a treated space
B. Act only as a surface repellent
C. Remain only on treated materials
D. Destroy pests through physical removal
Answer: A. Create a toxic gas that penetrates a treated space
Fumigants work by producing gases or vapors that penetrate enclosed
areas, materials, and pest hiding places to control target organisms.
3. Before applying a fumigant, the applicator must first:
A. Increase the temperature of the structure
B. Remove all warning signs
C. Read and follow the product label
D. Open all windows and doors
Answer: C. Read and follow the product label
The pesticide label is the legal instruction document that specifies required
safety procedures, application methods, and restrictions.
4. Which factor most directly affects fumigant concentration during
treatment?
A. Wind direction outside the structure
B. Volume of the enclosed space
,C. Color of the building
D. Type of flooring only
Answer: B. Volume of the enclosed space
Fumigant dosage calculations depend heavily on the volume of the treated
area to achieve the required concentration.
5. A fumigation applicator should wear respiratory protection when:
A. The label requires it or exposure may occur
B. Working only outdoors
C. Handling empty boxes
D. Inspecting untreated areas
Answer: A. The label requires it or exposure may occur

B. Large mammals only
C. Birds only
D. Aquatic organisms only
Answer: A. Stored product insects
, Fumigation is commonly used against insects in stored commodities
because gases can penetrate materials where insects hide.
7. The restricted entry interval (REI) indicates:
A. The time before a treated area may safely be reentered
B. The expiration date of the pesticide
C. The storage temperature
D. The mixing speed
Answer: A. The time before a treated area may safely be reentered
REI requirements protect people from exposure after pesticide application
until conditions are considered safe.
8. A fumigated structure must be properly sealed to:
A. Prevent gas leakage and maintain concentration
B. Increase lighting inside
C. Reduce humidity permanently
D. Eliminate the need for monitoring
Answer: A. Prevent gas leakage and maintain concentration
Proper sealing keeps the fumigant at effective levels and prevents
hazardous exposure outside the treatment area.
