of the fumigant. Do not wear gloves or rubber boots. Do not reuse
clothing or shoes that have become contaminated with liquid SF until
thoroughly aerated and cleaned.
If SF Is Inhaled
An individual who has inhaled high concentrations of SF may exhibit
the following symptoms:
◆ Slowed or garbled speech
◆ Slowed body movements
◆ Dulled awareness
◆ Nausea
◆ Difficulty in breathing
◆ Numbness of the extremities
If any of the above symptoms appear, then immediately do the
following:
◆ Remove the victim to fresh air.
◆ Put victim at complete rest.
◆ Keep the victim warm and see that breathing is normal and
unhampered. If breathing has stopped, give artificial respiration.
◆ Do not give anything by mouth to an unconscious person.
◆ Obtain medical assistance.
If Liquid SF Is Spilled on the Skin
Immediately apply water to the contaminated area of clothing before
removing. Wash contaminated skin thoroughly or shower.
If Liquid SF Is in the Eyes
Flush with plenty of water for at least 20 minutes, and get medical
attention. Damage to the eye may result from cold or freezing
temperatures.

Properties and Use
Phosphine (generally abbreviated as PH) may be generated from either
aluminum phosphide (AP) or magnesium phosphide (MP).
Aluminum phosphide and magnesium phosphide are available under
various trade names (see page-5-4-28) as tablets, pellets, prepacs,
bags, or plates. For example, each pellet of Phostoxin weighs 0.6
grams and yields approximately 0.2 grams of PH and each tablet
weighs 3 g and yields approximately 1 g of PH. Each 34 g bag or sachet
of Detia yields 11.4 g of PH. Each plate of Fumi-Cel weighs 117 g,
contains 32.3 percent MP and liberates 33 g of PH. A high humidity
(40 percent or more) is needed to generate the gas, and temperatures
above 40 °F are needed to produce satisfactory results.
In the presence of moisture, phosphine (hydrogen phosphide, PH3), a
colorless gas, is emitted. PH boils at -87.8 °C (-126 °F), is slightly
soluble in water, has excellent penetrative power, and has
approximately the same density as air. The lower level of flammability
is 1.79 percent in air.

Flashpoint is 212 °F. Direct contact with a liquid could cause
spontaneous combustion. In case of fire, a CO2 dry chemical fire
extinguisher should be used. Never use water. PH has an odor somewhat
like garlic, which enables the gas to serve as its own warning agent.
However, under some conditions, the odor may be lost, even at high
toxic concentrations. Ammonia and carbon dioxide are also produced,
which act as fire retardants.
Copper, brass, gold, and silver are severely damaged by PH. Other
metals react to some extent, especially in high humidity. Normally,
only electrical or electronic equipment (especially the contact points)
and some household effects would be affected.
PH is used to control insects found with both plant and animal
commodities, especially stored products, throughout the world. The
program use of PH for commodities other than cotton, tobacco, and
wood products may be limited because of the long exposure periods
required compared to other fumigants. For some insects, long
exposure to low concentrations is more effective than short exposure
to high concentrations. The germination of most seeds does not seem
to be affected, even with schedules higher than normally
recommended for insecticidal use. Phosphine should not be used for
fumigating growing plants, cut flowers and greenery, fresh fruits, or
