This should be carried out in open air and respiratory protection may be required. At no time should the deactivation drum be covered. No more than about 45 to 50 lbs. Prepacs, Ropes, and Fumex may ignite during wet deactivation if they are allowed to float to the surface.
Allow the mixture to stand, with occasional stirring, for about 36 hours. The resultant slurry of dust or packaged product will then be safe for disposal. Dispose of the slurry of deactivated material, with or without preliminary decanting, at a sanitary landfill or other suitable site approved by local authorities. Where permissible, this slurry may be poured into a storm sewer or out onto the ground.
If properly exposed, the grayish-white residual dust after a fumigation will not be a hazardous waste and normally contains only a very small amount of unreacted aluminum phosphide. This waste will be safe for disposal. However, the spent residual dust from incompletely exposed Phostoxin, DetiaPhos or Fumex may require special care.
Triple rinse tablet and pellet flasks and stoppers with water. Then offer for recycling or reconditioning, or puncture and dispose of in a sanitary landfill, or by other procedures approved by state and local authorities.
Rinsate may be disposed of in a storm sewer, sanitary landfill or by other approved procedures. Or, it is permissible to remove lids and expose empty flasks to atmospheric conditions until the residue in the flasks is reacted. Then puncture and dispose of in a sanitary landfill or other approved site, or by other procedures approved by state and local authorities.
Since containers for Prepacs, Ropes, and Fumex are contacted only by phosphine gas, they need not be triple rinsed prior to disposal. Some local and state waste disposal regulations may vary from the following recommendations. Disposal procedures should be reviewed with appropriate authorities to ensure compliance with local regulations. Confinement of partially spent residual materials, as in a closed container, or collection and storage of large quantities of dust may result in a fire or explosion hazard.
Small amounts of hydrogen phosphide may be given off from unreacted aluminum phosphide, and confinement of the gas may result in a flash.
In open areas, small amounts of spent residual dust or spent packaged products may be disposed of on site by burial or by spreading over the land surface away from inhabited buildings. Residual dust from Phostoxin, DetiaPhos and Fumex may also be collected and disposed of at a sanitary landfill, or other approved sites or by other procedures approved by Federal, State or Local authorities. Larger amounts, up to about one-half case, may be collected in burlap, cotton or other types of porous cloth bags for transportation in an open vehicle to the disposal site.
Do not collect dust from more than 7 flasks of tablets, 10 flasks of pellets about 11 kg or 25 lbs. Do not pile cloth bags together. Do not use this method for partially spent or "green" dust. Caution: Do not collect dust in large drums, dumpsters, plastic bags or other containers where confinement may occur. Deactivation of Partially Spent Phostoxin Prepacs and Ropes and Fumex Bags: Packaged products, such as Phostoxin Prepacs, Ropes, and Fumex bags, which are only partially spent may be rendered inactive by either a "dry" or "wet" deactivation method.
Protect the partially spent Phostoxin and Fumex from rain. The deactivated Prepacs, Ropes, and Fumex may then be taken to an approved site for incineration or burial at periodic intervals or whenever the wire container is full. Caution: Storage of partially spent Prepacs and Ropes in closed containers may result in a fire hazard upon opening the container.
Alternatively, partially spent Prepacs, Ropes and bags and residual dust from phosphine fumigations may be treated by the "wet" deactivation method as follows:. Deactivating solution is prepared by adding the appropriate amount of low sudsing detergent or surface active agent to water in a drum or other suitable container. Immerse spent Prepacs, Ropes and Fumex or slowly pour residual dust into the deactivating solution while stirring so as to thoroughly wet all of the spent material.
Keep immersed for about 36 hours. This should be done in the open air and not in the fumigated structure. Dust from Phostoxin tablets or pellets should be mixed into no less than about 10 gallons of water-detergent solution for each case of spent material.
Dispose of the deactivated Prepacs, Ropes, and Fumex or dust-water suspension, with or without preliminary decanting, at a sanitary landfill or other suitable site approved by local authorities. Where permissible, the slurry may be poured into a storm sewer or out onto the ground. Caution: Respiratory protection may be required during wet deactivation. Do not cover the container at any time. Do not dispose of dust in a toilet.
Do not allow quantities of dry, spent dust from Phostoxin to be collected or stored without deactivation. Post as a pesticide storage area. Do not store in buildings inhabited by humans or domestic animals. Other Precautions: 1. Do not allow water or other liquids to contact Phostoxin, DetiaPhos or Fumex.
Do not pile up large quantities of Phostoxin, DetiaPhos or Fumex during fumigation or disposal. Open containers of Phostoxin, DetiaPhos or Fumex only in open air. Do not open in a flammable atmosphere. Hydrogen phosphide in the head space of containers may flash upon exposure to atmospheric oxygen.
Phostoxin, DetiaPhos and Fumex are restricted use pesticides due to acute inhalation toxicity of highly toxic hydrogen phosphide phosphine, PH3 gas. For retail sale to and use only by certified applicators or persons under their direct supervision and only for those uses covered by the certified applicator's certification. See EPA approved labeling for additional precautions and directions for use. Protective Clothing: Wear gloves when handling aluminum phosphide tablets, pellets or dust.
