fumigation should wear an SCBA. Do not eat or smoke while
dispensing AP, MP, or any pesticide, and not until after washing. Wash
thoroughly after handling any pesticide. SCBA must be immediately
available and must be used by persons who may be exposed to
phosphine concentration above the threshold limit value (TLV).
Respiratory protection will be worn by the PPQ Officer when within 30 feet of
the enclosure under treatment
Threshold limit values for phosphine are as follows:
◆ Single exposure for continuous daily 8-hour exposure = 0.3 ppm.
◆ Short term exposure limit (STEL) = 1 ppm or 1 mg/m3.
◆ The threshold level of odor to the human nose is considered to
range from 0.005 to 0.5 ppm.

Safety
In addition to instructions and precautions found on the label, be
certain to:
◆ Study and follow the recommended application procedure.
◆ Comply with all regulations.
◆ Allow only personnel properly trained in the use of phosphine
products to conduct fumigations under the monitoring of a
certified pesticide applicator.
◆ Ensure that first aid equipment and information are readily
available.
◆ Check that approved respiratory protection (SCBA) is readily
available for each applicator.
◆ Placard the area to be fumigated and an area extending 30 feet
from the fumigation enclosure (or the entire building if less than
30 feet to the walls). Placards must include the name of the
chemical, date of the fumigation, and name, address, and
telephone number of applicator. See fumigant label for proper
wording.
◆ Always work in pairs, never alone. At least two people trained in
the use of the fumigant must be present during the introduction
of the fumigant, and the testing and aeration periods.
◆ Never smoke, eat, or drink while handling phosphine producing
materials.
◆ Always wash hands after handling phosphine materials.
◆ Never save excess or partially used packets, plates, etc. It cannot
and must not be done. Phosphine gas will evolve and constitute a
serious safety hazard. Dispose of all opened material following
label instructions.
◆ Remove placards when aeration is complete and concentrations
are below the TLV. Only certified pesticide applicators should be
used to remove placards.
◆ Mechanically unload grain treated with phosphine. Dust from
the residue may release a small amount of phosphine when
particles land on the moist mucous membrane of the nose or
mouth.
◆ Never use phosphine in vacuum fumigation, and never pull a
vacuum during chamber aeration. This compound is unstable at
reduced pressure that can occur during aeration.

Disposal of Residue
Following treatment with AP, a powdery residue, essentially aluminum
hydroxide, will remain in the envelope. This material should be
collected and mixed in a container of water to which liquid detergent
has been added (2 tablespoons of detergent per gallon of water). The
liquid should then be buried or deposited in an approved pesticide
disposal landfill.
Following treatment with MP, the plates may be disposed of by burial
in an approved landfill or by burning where approved by local
ordinances.
First Aid Treatment
Immediate warning signs resulting from exposure to high
concentration of PH include nausea, vomiting, and diarrhea.
Progressive signs include vertigo, chest pains, dry cough, choking,
intense thirst, enlarged pupils, and possible coma. Get the victim to
fresh air, treat for shock, and call a physician.
Bulk Fumigations
Sealing
Make the fumigation enclosure as gas tight as possible. Phosphine can
penetrate polyethylene tarpaulins at a very low rate; 4-mil tarpaulins
can be used only once; 6-mil tarpaulins should be used whenever
possible.
Probing
When large quantities of grain or other commodity in bulk are to be
treated, it will be necessary to “probe” tablets or pellets into the mass
of the commodity for adequate distribution. Specially constructed
probes made of steel tubing 1 1/4 inch in diameter are generally
available as described below:
Important
Refer to the section for tarpaulin fumigation with methyl bromide for additional
information on the following:
- selecting fumigation sites
- placing gas sampling tubes
- sealing tarpaulins
- taking concentration readings
