1. What is the primary purpose of fumigation?
A. To fertilize plants
B. To disinfect surfaces
C. To control pests in stored products or structures
D. To improve soil quality
Rationale: Fumigation is specifically used to eliminate or
control pests in structures, commodities, or soil, using gaseous
pesticides.
2. Which of the following is a commonly used fumigant?
A. Glyphosate
B. Borax
C. Methyl bromide
D. Copper sulfate
Rationale: Methyl bromide is a widely recognized fumigant
used for pest control, although its use is restricted due to
environmental concerns.
,3. Before fumigation, what is a critical safety procedure?
A. Adding water to the area
B. Evacuating people and animals from the area
C. Increasing the room temperature
D. Turning on air conditioning
Rationale: Fumigants are toxic, so all humans and animals
must be evacuated to prevent poisoning.
4. What personal protective equipment (PPE) is essential for
handling fumigants?
A. Gloves only
B. Safety glasses only
C. Respirators, gloves, and protective clothing
D. Hard hats
Rationale: Fumigants are often highly toxic; respirators
protect from inhalation, gloves and protective clothing
prevent skin contact.
5. Which factor significantly affects fumigant penetration?
A. Color of the fumigant
B. Temperature and moisture of the treated area
C. Size of the pesticide container
D. Brand of fumigant
Rationale: Temperature and moisture influence the gas’s
ability to penetrate materials and reach pests.
,6. How is methyl bromide primarily applied?
A. Spraying as a liquid
B. As a gas or vapor
C. As a powder
D. Mixed with water and spread
Rationale: Methyl bromide is a gaseous fumigant and works
by penetrating the area as a vapor to kill pests.
7. Which of the following is a symptom of fumigant exposure?
A. Improved vision
B. Headache and dizziness
C. Increased appetite
D. Rapid hair growth
Rationale: Exposure to fumigants can cause neurological
symptoms like headaches, dizziness, nausea, and respiratory
distress.
8. What is the primary environmental concern with methyl
bromide?
A. Soil erosion
B. Water pollution
C. Ozone layer depletion
D. Acid rain
Rationale: Methyl bromide is an ozone-depleting substance,
which has led to strict regulations on its use.
, 9. When fumigating a grain storage facility, what must be done
first?
A. Apply fertilizer
B. Seal the facility to prevent gas leakage
C. Spray water
D. Remove all pests manually
Rationale: Proper sealing ensures that the fumigant remains
concentrated and effective throughout the structure.
10. Which device is used to monitor fumigant concentration in
air?
A. Thermometer
B. Hygrometer
C. Gas detector or fumigant analyzer
D. Pressure gauge
Rationale: Gas detectors measure fumigant levels to ensure
safe concentrations and proper efficacy.
11. What is the typical action to take after fumigation is
complete?
A. Immediately re-enter the area without precautions
B. Open windows for 5 minutes only
C. Ventilate the area thoroughly and test for residual gas
D. Spray insecticide on top of the fumigant
Rationale: Proper ventilation and testing ensure that no toxic
gas remains before re-entry.
