California (CA) Branch 1 (Fumigation)
Field Representative Exam | Latest
Verified Questions and Detailed Answers
OVERVIEW DESCRIPTION
This comprehensive set of multiple choice questions is designed for the
California Branch 1 (Fumigation) Field Representative Exam,
administered by the state's Structural Pest Control Board (SPCB). The
exam assesses a candidate's competency in the safe and effective use of
lethal gases for structural pest control, covering key knowledge domains
such as fumigants and label comprehension, personal protective
equipment and safety precautions, proper fumigation preparation,
application, aeration, and clearance procedures, the California Aeration
Plan (CAP) and other state rules and regulations, pest identification and
biology, and essential business and law practices.

QUESTION 1
Which gas is the active ingredient in Vikane fumigant?
A) Methyl bromide
B) Sulfuryl fluoride
C) Phosphine
D) Chloropicrin
CORRECT ANSWER: B
,EXPERT RATIONALE:
Vikane's active ingredient is sulfuryl fluoride, a colorless, odorless gas
used for structural fumigation. Methyl bromide is a separate fumigant
often sold as Zythor or other brands.
QUESTION 2
The California Aeration Plan (CAP) for sulfuryl fluoride
fumigations requires clearance monitoring until the concentration at
breathing zone height is at or below:
A) 1 ppm
B) 5 ppm
C) 10 ppm
D) 15 ppm
CORRECT ANSWER: B
EXPERT RATIONALE:
CAP mandates that re-entry cannot occur until sulfuryl fluoride levels
are 5 ppm or less, verified by a direct-reading device. This protects
occupants from overexposure.
QUESTION 3
A Branch 1 Field Representative who intends to change employers
must provide written notice to the current employer at least how
many days before the change?
A) 5 days
B) 10 days
,C) 15 days
D) 30 days
CORRECT ANSWER: B
EXPERT RATIONALE:
Pursuant to the Structural Pest Control Act, a field representative must
give 10 days' written notice before changing employment. The employer
must then notify the board within 10 days of termination.
QUESTION 4
What is the primary purpose of introducing chloropicrin during a
Vikane fumigation?
A) Increase fumigant toxicity
B) Serve as a warning agent
C) Accelerate aeration
D) Reduce dosage needed
CORRECT ANSWER: B
EXPERT RATIONALE:
Sulfuryl fluoride is odorless, so chloropicrin (a tear gas) is added as a
warning agent to alert anyone inadvertently entering the fumigated
space. It does not enhance pesticidal activity.
QUESTION 5
Which of the following drywood termite species is most commonly
targeted by structural fumigation in California?
, A) Reticulitermes flavipes
B) Incisitermes minor
C) Coptotermes formosanus
D) Zootermopsis angusticollis
CORRECT ANSWER: B
EXPERT RATIONALE:
Incisitermes minor, the western drywood termite, is a prevalent wood-
destroying pest in California and is commonly controlled by whole-
structure fumigation. Other species listed are subterranean or dampwood
termites.
QUESTION 6
After releasing sulfuryl fluoride into a structure, the fumigator must
verify that lethal concentrations are maintained. Which device is
typically used to measure gas concentration during fumigation?
A) Photoionization detector
B) Fumiscopе or thermal conductivity analyzer
C) Oxygen meter
D) Infrared thermometer
CORRECT ANSWER: B
EXPERT RATIONALE:
Fumiscopе (thermal conductivity) is standard for monitoring sulfuryl
fluoride or methyl bromide levels inside the fumigated space. Other
devices like SF-ExplorIR are used for low-level clearance.
