Question 1 of 50
A fumigation crew posts warning signs in English only around a single-family residence
in Los Angeles. Several neighbors primarily speak Spanish. A county agricultural
inspector happens to drive by and notices the signs before the fumigation begins.
A. The signs are compliant since English is the federally required language
B. The crew must add Spanish signs only if the property owner requests it
C. The signs are acceptable if the fumigator also gives verbal notice in Spanish
D. California regulations require warning signs to be posted in both English and Spanish
for residential fumigations ✓ CORRECT
Correct Answer: D
Rationale: California DPR requires bilingual warning signs for structural fumigation to
ensure all occupants and neighbors understand the hazard. English-only signs do not
meet this requirement even if verbal notice is given. Most counties enforce this strictly
and will stop a job if signs are not bilingual.
,Question 2 of 50
A homeowner in Sacramento calls a pest control company on Monday morning
requesting fumigation for drywood termites. The company wants to begin the job
Wednesday morning and plans to deliver the written notice Tuesday evening.
A. The notice is timely because it is delivered before the job starts
B. The company must provide at least 48 hours written notice before the fumigation
begins ✓ CORRECT
C. A 24-hour verbal notice is sufficient for existing customers
D. Written notice is only required for commercial buildings
Correct Answer: B
Rationale: California regulations require at least 48 hours written notice before
residential fumigation begins. Delivering notice Tuesday evening for a Wednesday
morning start does not meet this minimum. The notice period allows occupants to
prepare and make alternative arrangements.
Question 3 of 50
A licensed Branch 3 operator sends his registered technician to a job site to post
warning signs and begin tenting while the operator finishes paperwork at the office. The
technician has completed training but is not yet licensed.
A. The technician may perform these tasks if the operator is reachable by phone
B. The technician can work alone for up to two hours before the operator arrives
C. A licensed operator must be physically present during fumigation operations; this
violates the two-person rule ✓ CORRECT
D. Only the introduction of fumigant requires two persons; preparation can be done solo
Correct Answer: C
Rationale: California's two-person rule requires a licensed operator to be physically
present during fumigation operations; sending an unlicensed technician alone violates
, this safety requirement. Phone availability does not substitute for physical presence.
This rule exists because emergencies require immediate qualified response.
Question 4 of 50
A pest control company begins a warehouse fumigation without a written fumigation
management plan, claiming the job is routine and they have done hundreds like it.
A. A fumigation management plan is required for every fumigation operation regardless
of experience ✓ CORRECT
B. Written plans are only required for the first fumigation at a new site
C. Verbal plans are acceptable for routine residential jobs
D. Management plans are only required when using methyl bromide
Correct Answer: A
Rationale: A fumigation management plan is required for every fumigation to document
procedures, safety measures, and emergency contacts. Routine status does not exempt
an operation from this planning requirement. The plan must be site-specific and
available to all crew members.
Question 5 of 50
A pest control company stores sulfuryl fluoride cylinders in a locked utility shed
alongside bags of ammonium nitrate fertilizer and cases of motor oil.
A. Acceptable because all items are stored in a locked area
B. The storage is compliant if the shed has a "Danger" sign posted
C. Only food and feed items must be kept separate from fumigants
D. This violates regulations because fumigants must be stored separately from
fertilizers and other incompatible materials ✓ CORRECT
Correct Answer: D
Rationale: Sulfuryl fluoride must be stored separately from incompatible materials like
fertilizers and petroleum products to prevent dangerous chemical reactions. A locked
