SUBSTANCE NAME
VAPORPH 3 OS® phosphine fumigant
phosphine
GENERAL STATEMENT
VAPORPH 3 OS phosphine fumigant is a cylinderized source of pure phosphine for the fumigation of agricultural
post-harvest products or storage structures. Pure phosphine gas is blended with carbon dioxide or forced air to
produce a nonflammable fumigant gas for on-site use in controlling pests in enclosed empty spaces and enclosed
space containing stored listed raw agricultural commodities, processed foods, stored tobacco, animal feeds, and
nonfood products. Not for use on barges. Not for burrow treatment. VAPORPH3OS is designed for use in
conjunction with Cytec-approved blending equipment capable of diluting the phosphine concentration to below its
lower flammability limit of 1.8% (vol.). VAPORPH 3 OS is pyrophoric and intended for use in accordance with its
approved pesticide label. For details refer to the VAPORPH 3 OS Phosphine Fumigant Application Manual. It is a
violation of US federal law to use this product in a manner inconsistent with its labeling.

HEALTH EFFECTS
Based on the classification of the substance (REGULATION (EC) No 1272/2008) phosphine is classified to be
fatal if inhaled and to cause skin burns and eye damage. Workers should be properly instructed and
supervised in the handling of the substance.
EFFECT ASSESSMENT
Acute Toxicity
(oral/dermal/inhalation)
Irritation/Corrosivity
(skin/eye/respiratory tract)
Sensitization
(skin/respiratory tract)
Repeated Exposure
RESULT
Highly toxic. Phosphine may be fatal if inhaled.
Phosphine may cause skin burns and eye damage.
Phosphine is not known to be a skin sensitizer.
Carcinogenicity
Reproductive Toxicity
ENVIRONMENTAL EFFECTS
Phosphine is not classified as harmful by repeated exposure. A
LOAEL of 4.5 ppm and a NOAEL of 1 ppm were observed in mice
after exposures of 6 hours/day, 5 days/week for 13 weeks.
Phosphine caused chromosomal aberrations in male rat bone
marrow and lymphocytes. No effects were observed in female rats.
This substance is not classified as a carcinogen.
This substance is not classified as causing reproductive toxicity.
EFFECT ASSESSMENT
Aquatic Toxicity
RESULT
Phosphine is highly toxic to aquatic life.
Mutagenicity
FATE AND BEHAVIOR
Biodegradation
Bioaccumulation potential
PBT/vPvB conclusion
EXPOSURE
RESULT
Phosphine rapidly degrades in biological systems.
Phosphine has a low potential for bio-accumulation.
Phosphine is not considered to be persistent, bioaccumulating nor
toxic (PBT). This substance is not considered to be very persistent
nor very bioaccumulating (vPvB).

Product Safety Summary
Human Health
VAPORPH 3 OS® phosphine fumigant is used solely in agricultural applications. When the recommended risk
management measures and required operational conditions are observed, worker exposures are expected to
be minimal during the post-harvest use of VAPORPH 3 OS. Significant consumer exposure to phosphine,
including residues in food, is not expected.
Environment
Due to physical/chemical characteristics phosphine has a low potential for bioaccumulation, rapidly degrades
in biological systems and accumulation in organisms is not expected. No direct release of phosphine to soil is
expected during use.
RISK MANAGEMENT RECOMMENDATIONS
May be fatal if inhaled. The liquid may cause burns. Avoid contact with skin and eyes and avoid breathing
vapor. Keep animals, children and unauthorized persons away from area under treatment, until area is shown
to be free from phosphine gas, as indicated by a gas measuring device. Working in an area with undetermined
concentrations requires a self-contained breathing apparatus (SCBA) with full face-piece operated in a
pressure-demand mode. Do not get in eyes, in nose, on skin or on clothing. Do not eat, drink or smoke while
handling VAPORPH3OS® Phosphine Fumigant. Phosphine gas may deaden the sense of smell. Do not depend
solely on the odor to detect VAPORPH3OS® Phosphine Fumigant. The following are first aid measures that
should be taken if exposure should occur:
•
•
•
•
Ingestion: Not an expected route of exposure.
Skin Contact: May cause frostbite to unprotected skin upon contact with dispensing equipment
while gas is discharged rapidly. Take off contaminated clothing and allow clothes to aerate in
ventilated room prior to laundering. Call a poison control center or doctor for treatment advice.
Eye Contact: Hold eye open and rinse slowly and gently with cool water for 15-20 minutes in
case of freezing or cryogenic "burns." Do not rinse eyes with hot or even tepid water. Remove
contact lenses, if present, after the first 5 minutes, and then continue rinsing. Call a poison
control center or doctor for treatment advice. Never introduce oil or ointment into eyes without
medical advice.
Inhalation: Move person to fresh air. If person is not breathing, call 911 or an ambulance, and
then give artificial respiration, preferably mouth-to-mouth if possible. • Call a poison control
center or doctor for further treatment advice.
Rescuers within the areas of potentially unsafe levels of this product (the "HOT ZONE") should
employ appropriate personal protective equipment such as a positive pressure, self-contained
respirator (self-contained breathing apparatus; SCBA) during the rescue of the victim. Call a
poison control center or doctor for further treatment advice.
In the event of an accidental release, evacuate the area immediately. A response into the leak area should only
be attempted by trained emergency responders. If it is possible to shut off the source of the leak from a
remote area, it should be done. Otherwise, evacuate the area and call for assistance.

Product Safety Summary
ENVIRONMENTAL PRECAUTIONS
Environmental exposure from VAPORPH3OS® Phosphine Fumigant is not expected if handled according to
the approved pesticide label.
GOVERNMENT AGENCY REVIEW
Phosphine is listed in the following Chemical Inventories: TSCA, ENCS, ISHL, AICS, DSL, KECL, PICCS and
IESCS.
REGULATORY INFORMATION/CLASSIFICATION AND LABELING
Classification of the substance according to REGULATION (EC) No 1272/2008:
Flam. Gas 1
Press. Gas
Acute Tox. 2
Skin Corr. 1B
Aquatic Acute 1
Extremely flammable gas
Fatal if inhaled
Toxic by inhalation
Causes severe skin burns and eye damage
Very toxic to aquatic life
Other precautions include:
Use only outdoors or in a well-ventilated area. No smoking. Keep away from heat/sparks/open flames/hot
surfaces. Do not extinguish a leaking gas fire unless the leak can be stopped safely. Eliminate all ignition
sources if safe to do so. Protect from sunlight. Store in a well-ventilated place. Keep container tightly closed.
Store locked up. Wash contaminated clothing before reuse. Collect spillage or contaminated soil and dispose
in accordance with local and national regulations. Once used, VAPORPH 3 OS® Phosphine Fumigant cylinders
are to be returned only to an authorized distributor or their designated point of return. This applies to all
cylinders, regardless of the quantity of material remaining in the cylinder.
CONCLUSION
VAPORPH 3 OS® Phosphine Fumigant is used solely for the fumigation of agricultural post-harvest products or
storage structures. Before using VAPORPH 3 OS®, all workers should review the Material Safety Data Sheet and
receive training on safety and handling procedures, and recommended personal protective equipment.
Considering these precautions, the potential level of exposure to phosphine, in normal use, is considered to be
very low.
