Structural Fumigation & How To Measure a Structure

Vikane specialty gas fumigant may be used for the control of Existing infestations of listed insects and related pests such as drywood termites, Formosan termites, powder post beetles, death watch beetles, old house borers, bedbugs, cockroaches, clothes moths, rodents (rats, mice), and the larvae and adults of carpet beetles (except egg stage), oriental, American, and brown-banded cockroaches.    True or False

If inhaled: Get exposed person to fresh air. Keep warm and at rest. Make sure person can breathe freely. If breathing has stopped, give artificial respiration. Do not put anything in the mouth of an unconscious person. Call a poison control center or doctor for further treatment advice.   True or False

Two persons trained in the use of Vikane, at least one being an applicator licensed/certified by the state, must be present during introduction of fumigant, reentry prior to aeration, and during the initiation of the initial aeration procedure when exposure exceeds 1 ppm. Two persons need not be present if monitoring is conducted remotely (outside the area being fumigated) and no one enters
the fumigated structure.   True or False

Protective Clothing:  Do not wear gloves or rubber boots. Do not reuse clothing or shoes that have become contaminated with liquid Vikane until thoroughly aerated.  True or False

Transport cylinders capped and secured in an upright position. Do not transport cylinders that are unsecured or laying on their side, unless they are in an enclosed truck.   True or False

Prior to the parties entering into a fumigation agreement, the Fact Sheet for Vikane must be provided to an adult occupant of the structure to be fumigated or of each currently occupied unit in multi-unit structures.    True or False

Food, feed, drugs (including tobacco products), and medicinals (including those items in refrigerators and freezers) can remain in the structure if they are in plastic, glass, or metal bottles, cans, or jars with the original manufacturer’s air-tight seal intact.   True or False

Food, feed, drugs (including tobacco products), and medicinals (including those items in refrigerators and freezers) not in plastic, glass, or metal bottles, cans, or jars with the original manufacturer’s air-tight seal intact, need to be removed from the fumigation site, or double bagged in Nylofume® bags, or tightly sealed trash bags.  True or False

Open operable internal doors, internal openings to attics and sub areas, storage chests, cabinets, drawers, closets, and appliances (such as washers, dishwashers, dryers, microwave or conventional ovens, etc.).  True or False

There are four purposes for fans in a structural fumigation:
1. Fumigant introduction
2. Equilibrium and circulation
3. Aeration
4. Keeping workers cool

 True or False

After fumigant introduction is completed and equilibrium is obtained, fans may be left operating during the fumigation exposure period if desired. Continuous circulation using fans during the fumigant exposure period will not detectably affect the loss rate (half-loss time, HLT) of Vikane for an adequately sealed structure.   True or False

When preparing for the fumigation, it is recommended to plan ahead for the aeration period and take steps to aid aeration by strategic placement of fans and other aeration tools. Fans are excellent aids in attaining rapid aeration and are important when cross ventilation is poor. The fans used for fumigant introduction and distribution may need to be repositioned to enhance aeration.   True or False

Use tarps made of materials that will adequately confine Vikane for the required time, such as 4 to 6 mil polyethylene, laminated polyethylene, vinyl coated nylon, neoprene coated nylon, and PVC (polyvinyl chloride) coated nylon.   True or False

Posting of Fumigated Areas: 
Vikane is a toxic gas. All entrances of the fumigated environment and any connected area must be posted with warning signs. Some states have extensive regulations regarding warning sign formatting, size, information content, placement, and weather durability. The warning signs must be printed with:
1. The signal word DANGER/PELIGRO and the SKULL and CROSSBONES symbol.
2. The statement “Area under fumigation, DO NOT ENTER/NO ENTRE.”
3. The date of fumigation.
4. Name of fumigant used.
5. Name, address, and telephone number of the applicator. 

True or False

A structure 15 feet wide, 20 feet long and 9 feet high equals 2,400 cubic feet.    True or False

The purpose of opening windows in tarped buildings during the fumigant exposure period is to reduce the time for the fumigant to reach equilibrium inside the building and between the building and the tarps. For wood-destroying insects, this can be necessary for sufficient fumigant exposure of target pests infesting external structural features such as wood eaves and soffits. Windows are not considered normal entries and should be opened, if operable and as permitted by local and state regulations, during fumigation of tarped buildings. Consult state and local regulations for any supplementary instructions and restrictions on opening windows.    True or False

The rate of flow of Vikane should be controlled by the ID and length of hose and not be
restricting flow through the valve.   True or False

The most efficient use of the aeration fans is to position so airflow is moving in one direction.  This is done by positioning fans for fresh air intake in openings on one side of the structure and fans for exhausting fumigant in openings on the opposite side of the structure.   True or False

Do not allow reoccupancy of any fumigated area until the aeration and clearing process is complete according to directions and concentrations of Vikane do not exceed 12 ppm as determined by the use of a detection device with sufficient sensitivity.   True or False

Live organisms which are not specific targets of the fumigation may found within the fumigated space following aeration. This does not indicate the fumigation failed to control the target pests because lethal dosage requirements may be higher for non-target organisms than for the target pest(s). Also, the non-target organism may have entered the structure during the aeration period.    True or False
