Q1: Nevada Category C4 Fumigation definition?
A. Only spray liquid insecticides
B. Fumigation control of pests using fumigants - toxic gases that penetrate - structural fumigation for drywood termites bed bugs,
commodity fumigation stored products, soil fumigation - requires specialized license due to high hazard
C. Only traps
D. Only bait gels
Answer & ULTRA-Detailed Rationale:
B. Fumigation control of pests using fumigants - toxic gases that penetrate - structural fumigation for drywood termites bed
bugs, commodity fumigation stored products, soil fumigation - requires specialized license due to high hazard
CONCEPT: Scope C4. CORRECT - A: C4 Fumigation per Nevada Dept Agriculture NDA: control of pests using fumigants - toxic
gases that penetrate voids, wood, commodities - e.g., sulfuryl fluoride Vikane for drywood termites bed bugs, phosphine
aluminum phosphide for stored products, methyl bromide (restricted), chloropicrin warning agent, magnesium phosphide.
Structural fumigation tenting, commodity fumigation grain, soil fumigation (may also need B category). Requires specialized license due
to high acute inhalation hazard, requires FMP Fumigation Management Plan. WHY B WRONG: Only spray liquid insecticides is general
pest C2 - not fumigation - fumigants are gases not liquids - different hazard - spray does not penetrate like gas. WHY C WRONG: Only
bait gels is cockroach ant - not fumigation - bait does not fumigate structure. WHY D WRONG: Only traps is monitoring - not fumigation -
fumigation kills all stages with gas. EXAM TIP: C4 = gases that penetrate - sulfuryl fluoride Vikane drywood termites, phosphine stored
products - high hazard requires FMP.
Q2: Fumigant mode of action - sulfuryl fluoride Vikane vs phosphine?
A. Sulfuryl fluoride inhibits glycolysis disrupts energy metabolism - phosphine inhibits cytochrome c oxidase disrupts respiration - both
gases penetrate - require specific temperature exposure time concentration
B. No mode of action
C. Both contact only no inhalation
D. Both repel pests only
Answer & ULTRA-Detailed Rationale:
A. Sulfuryl fluoride inhibits glycolysis disrupts energy metabolism - phosphine inhibits cytochrome c oxidase disrupts
respiration - both gases penetrate - require specific temperature exposure time concentration
CONCEPT: Mode of action fumigants. CORRECT - A: Sulfuryl fluoride Vikane inhibits glycolysis enzyme - disrupts energy
metabolism - kills by disrupting metabolism - used for drywood termites bed bugs. Phosphine from aluminum phosphide
magnesium phosphide inhibits cytochrome c oxidase in mitochondria - disrupts respiration - kills insects rodents. Both are
respiratory poisons gases penetrate - require specific temperature minimum e.g., 40F for sulfuryl fluoride, 40F for phosphine,
exposure time concentration product CT = concentration times time - must monitor gas. WHY B WRONG: Both contact only no
inhalation false - fumigants are inhalation hazards - gases inhaled - contact not primary - fumigants penetrate respiratory system. WHY C
WRONG: Both repel only false - fumigants kill not repel - lethal gases. WHY D WRONG: Mode of action exists - inhibits
energy/respiration. EXAM TIP: Phosphine = respiration inhibitor cytochrome oxidase - sulfuryl fluoride = glycolysis inhibitor.

,Q3: Fumigation Management Plan FMP - what must be included per label and Nevada?
A. Only date needed
B. No plan needed just apply
C. Only product name needed
D. FMP must include applicator name license, location, target pest, fumigant name EPA Reg No, rate dosage, temperature, exposure
time, sealing method, monitoring equipment, PPE, notification, posting, emergency plan, entry restrictions
Answer & ULTRA-Detailed Rationale:
D. FMP must include applicator name license, location, target pest, fumigant name EPA Reg No, rate dosage, temperature,
exposure time, sealing method, monitoring equipment, PPE, notification, posting, emergency plan, entry restrictions
CONCEPT: FMP required. CORRECT - A: Fumigation Management Plan FMP required per label and NAC 555 - must include:
applicator name license, location address structure, target pest, fumigant name EPA Reg No active ingredient, dosage rate,
temperature, exposure period, sealing method tent tarps tape, monitoring equipment Interscan or similar, PPE required SCBA,
notification to occupants neighbors fire dept, posting signs Danger Fumigation, emergency plan, entry restrictions, aeration
procedure, clearance testing. Must be completed before fumigation. WHY B WRONG: No plan needed just apply violates label - label
requires FMP - fumigation without FMP is violation - high hazard - could cause death. WHY C WRONG: Only product name insufficient -
FMP requires many elements - dosage temp exposure monitoring emergency. WHY D WRONG: Only date insufficient - need all
elements. EXAM TIP: FMP required before every fumigation - most tested document for C4.
Q4: Structural fumigation tenting - sealing and aeration - sulfuryl fluoride?
A. No sealing needed open tent
B. No monitoring needed
C. No aeration needed immediate re-entry
D. Structure covered with tarps sealed with sand snakes or clamps - introduce gas with fans for circulation - exposure 16-72 hrs
depending temp dosage - aeration with active aeration fans open tarps - clearance testing with Interscan detector must be 1 ppm or
less per label before re-entry
Answer & ULTRA-Detailed Rationale:
D. Structure covered with tarps sealed with sand snakes or clamps - introduce gas with fans for circulation - exposure 16-72
hrs depending temp dosage - aeration with active aeration fans open tarps - clearance testing with Interscan detector must be
1 ppm or less per label before re-entry
CONCEPT: Structural fumigation process. CORRECT - A: Structural fumigation: cover structure with tarps (Vikane), seal with
sand snakes or clamps to prevent leakage - introduce gas via cylinder with fans for circulation - exposure 16-72 hrs depending
temperature dosage target pest - aeration active aeration fans - open tarps from outside - clearance testing with Interscan or
similar detector must be 1 ppm or less sulfuryl fluoride per label before re-entry - often 5 ppm chloropicrin warning agent
irritant used with sulfuryl fluoride as warning. WHY B WRONG: No sealing needed open tent false - must seal to hold gas
concentration CT product - open tent leaks fails kill. WHY C WRONG: No aeration needed immediate re-entry false - gas remains lethal -
must aerate actively then test clearance - re-entry without clearance can cause death. WHY D WRONG: No monitoring needed false -
must monitor gas concentration during exposure and clearance - Interscan required. EXAM TIP: Clearance 1 ppm sulfuryl fluoride
before re-entry - memorize - aeration active fans.

,Q5: Phosphine aluminum phosphide - application and hazards?
A. Safe non-toxic no PPE
B. Can be applied with water
C. No placarding needed
D. Aluminum phosphide pellets/tablets react with moisture produce phosphine gas - highly toxic - requires FMP, 2-person rule,
respiratory protection SCBA or full-face with phosphine cartridge if allowed, monitoring, no water contact, placarding, aeration, no
entry during fumigation
Answer & ULTRA-Detailed Rationale:
D. Aluminum phosphide pellets/tablets react with moisture produce phosphine gas - highly toxic - requires FMP, 2-person rule,
respiratory protection SCBA or full-face with phosphine cartridge if allowed, monitoring, no water contact, placarding,
aeration, no entry during fumigation
CONCEPT: Phosphine hazard. CORRECT - A: Aluminum phosphide pellets tablets react with moisture humidity produce
phosphine gas PH3 - highly toxic - fatal if inhaled - requires FMP, 2-person rule never alone, respiratory protection SCBA or
full-face respirator with phosphine cartridge if concentration low and allowed per label (many labels require SCBA), continuous
monitoring with phosphine meter, no direct water contact (violent reaction fire), placarding Danger Pellet Fumigation Do Not
Enter, aeration outdoors, no entry during fumigation, buffer zones 100 ft. WHY B WRONG: Safe non-toxic false - phosphine highly
toxic - fatal - many deaths - must have PPE. WHY C WRONG: Can be applied with water false - water causes violent reaction releases
gas rapidly fire hazard - must avoid water - moisture in air enough. WHY D WRONG: No placarding needed false - placarding required
per label - Danger signs. EXAM TIP: Phosphine + water = fire hazard - never allow direct water contact - 2-person rule - SCBA - most
tested hazard.
Q6: Chloropicrin - purpose as warning agent?
A. Chloropicrin tear gas irritant added to sulfuryl fluoride or used alone - warning agent - causes eye irritation tearing warns of gas
presence - also has some insecticidal activity
B. Fertilizer
C. Only for soil
D. No purpose
Answer & ULTRA-Detailed Rationale:
A. Chloropicrin tear gas irritant added to sulfuryl fluoride or used alone - warning agent - causes eye irritation tearing warns of
gas presence - also has some insecticidal activity
CONCEPT: Chloropicrin warning. CORRECT - A: Chloropicrin CCl3NO2 tear gas irritant - added to sulfuryl fluoride Vikane at 5%
as warning agent - causes eye irritation tearing at low concentration warns occupants of gas presence - sulfuryl fluoride
odorless colorless needs warning agent - also has insecticidal fungicidal activity - used alone as soil fumigant. WHY B
WRONG: Fertilizer false - chloropicrin is fumigant irritant - not fertilizer. WHY C WRONG: No purpose false - purpose warning agent -
critical safety - prevents accidental exposure - many lives saved by tearing. WHY D WRONG: Only for soil false - used as warning agent
in structural fumigation and as soil fumigant - dual use. EXAM TIP: Chloropicrin = warning agent tear gas - causes tears warns of Vikane
which is odorless.

, Q7: Fumigant PPE - what is required per label?
A. Only dust mask
B. Only gloves
C. No PPE needed
D. PPE: chemical resistant suit, gloves, eye protection - respiratory: SCBA self-contained breathing apparatus or supplied air for entry
during fumigation or high concentration - full-face respirator with appropriate cartridge may be allowed for low concentrations per
label - must have 2-person present - no contact lenses
Answer & ULTRA-Detailed Rationale:
D. PPE: chemical resistant suit, gloves, eye protection - respiratory: SCBA self-contained breathing apparatus or supplied air
for entry during fumigation or high concentration - full-face respirator with appropriate cartridge may be allowed for low
concentrations per label - must have 2-person present - no contact lenses
CONCEPT: PPE fumigation high hazard. CORRECT - A: PPE: chemical resistant suit, gloves 14 mil nitrile, eye protection,

above IDLH or unknown - full-face respirator with phosphine or sulfuryl fluoride cartridge may be allowed for low
concentrations per label during application if monitoring shows below cartridge limit - must have 2-person present never alone
- no contact lenses (gas trapped). WHY B WRONG: No PPE false - fumigants fatal - PPE required - label PPE section. WHY C
WRONG: Only dust mask insufficient - dust mask does not protect against gas - need SCBA or gas cartridge respirator - dust mask
would cause death. WHY D WRONG: Only gloves insufficient - respiratory protection most important - inhalation hazard primary. EXAM
TIP: Fumigation = SCBA - never dust mask - 2-person rule.
Q8: Posting and notification - structural fumigation?
A. No notification needed
B. No posting needed
C. Must post Danger Fumigation Do Not Enter signs at all entrances, with skull and crossbones, fumigant name, date, applicator
