Answers (Verified Answers) Plus Rationale
2026 Q&A| Instant Download Pdf
1. What is the primary purpose of fumigation?
A. To repel insects
B. To sterilize soil nutrients
C. To control pests using toxic gases or vapors
D. To increase soil moisture
Rationale: Fumigation relies on poisonous gases that penetrate
enclosed spaces or commodities to eliminate pests.
2. Which property makes fumigants particularly hazardous?
A. Bright color
B. Sticky texture
C. Ability to spread as gases and be inhaled
D. Low density
,Rationale: Most fumigants are highly toxic by inhalation and can
rapidly disperse through air.
3. Before beginning a fumigation, an applicator should first:
A. Open all vents
B. Turn off warning signs
C. Inspect the site and prepare a fumigation plan
D. Remove all monitoring devices
Rationale: Careful planning and inspection reduce risks and improve
treatment effectiveness.
4. Why is sealing important during structural fumigation?
A. It reduces cleanup time.
B. It prevents fumigant leakage and maintains effective
concentrations.
C. It increases humidity.
D. It changes the fumigant color.
Rationale: Gas-tight sealing keeps the fumigant at lethal
concentrations while protecting surrounding areas.
,5. Which type of personal protective equipment is commonly required
when exposure is possible?
A. Cotton gloves only
B. Sandals
C. Baseball cap
D. Appropriate respiratory protection and other required PPE
Rationale: Respiratory protection is essential when engineering
controls cannot eliminate exposure.
6. Fumigants are most effective when:
A. Applied only during rain
B. Mixed with fertilizers
C. Proper concentration and exposure time are maintained
D. Sprayed in open fields without containment
Rationale: Successful fumigation depends on maintaining the correct
dosage over sufficient time.
7. Which factor can affect fumigant penetration?
, A. Moon phase
B. Temperature and commodity characteristics
C. Paint color
D. Wind direction indoors only
Rationale: Temperature and material properties influence gas
movement and pest control.
8. What is the purpose of warning signs during fumigation?
A. Decoration
B. Advertising services
C. Marking storage areas only
D. Alerting people to dangerous conditions and restricting entry
Rationale: Warning signs help prevent accidental exposure by
informing others of the hazard.
