VAPORPH3OS餂? Phosphine Fumigant
The probable oral lethal dose in humans is about 5 mg/kg. A study was conducted by Cyanamid with seven
groups of 10 rats (5/sex/group) exposed once for four hours to various levels of dynamically-generated vapor of
phosphine. The four hour LC50 (rat) for the combined sexes is 57 ppm. Symptoms of poisoning included
weakness, fatigue, headache, dizziness, and tightness of the chest.
Refer to Section 11 for toxicology information on the regulated components of this product.

4. FIRST AID MEASURES
Ingestion:
Not an expected route of exposure.
Skin Contact:
Take off immediately all contaminated clothing. Wear impermeable gloves. Wash immediately with plenty of water
and soap. Pay particular attention to skin crevices, nail folds, etc. Do not reuse contaminated clothing without
laundering. Do not reuse contaminated leatherware.
Eye Contact:
Rinse immediately with plenty of water for at least 15 minutes. Obtain medical attention immediately.
Inhalation:
Remove to fresh air. If breathing is difficult, give oxygen. Apply artificial respiration if patient is not breathing. Obtain
medical attention immediately.
_____________________________________________________________________________
5. FIRE-FIGHTING MEASURES
Extinguishing Media:
Use water spray, alcohol foam, carbon dioxide or dry chemical to extinguish fires.
Protective Equipment:
Firefighters, and others exposed, wear self-contained breathing apparatus. Wear full firefighting protective clothing.
See Section 8 (Exposure Controls/Personal Protection).
Special Hazards:
In case of fire, stop flow of gas if possible. Keep containers cool by spraying with water if exposed to fire. This
material is spontaneously flammable in air and may form explosive mixtures in air.
_____________________________________________________________________________
6. ACCIDENTAL RELEASE MEASURES
Personal Precautions:
Where exposure level is not known, wear approved, positive pressure, self-contained respirator. Where exposure
level is known, wear approved respirator suitable for level of exposure.
Methods For Cleaning Up:
Remove sources of ignition. Evacuate area. If burning, allow to burn until leak is stopped.

7. HANDLING AND STORAGE
HANDLING
Precautionary Measures: Do not breathe gas. Keep container closed. Use with adequate ventilation. Keep away
from heat, sparks and flame. Never drop cylinder. Keep cylinder out of sun and away from heat. X POISON X

VAPORPH3OS餂? Phosphine Fumigant
Handling Statements: Phosphine should be used in a well ventilated area, preferably in a hood with forced
ventilation. When transferring, the equipment should be flushed with an inert gas.
STORAGE
Areas containing this material should have fire-safe practices and electrical equipment in accordance with applicable
governmental regulations for products with the flashpoint as shown (Physical and Chemical Properties Section).
Cylinders should be stored in an assigned area which should be cool, dry, well ventilated and fire resistant.
Storage Temperature: Not applicable
_____________________________________________________________________________
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering Measures:
Utilize a closed system process where feasible. Where this material is not used in a closed system, good enclosure
and local exhaust ventilation should be provided to control exposure.
Respiratory Protection:
In case of insufficient ventilation, wear suitable respiratory equipment. If exposed to vapour or spray, wear self-
contained breathing apparatus. Continuously monitoring phosphine concentration in the workplace is recommended.
Emergency procedure should be established for phosphine leaks.
Eye Protection:
Wear eye/face protection. Provide eye wash fountain and safety shower in close proximity to points of potential
exposure.
Skin Protection:
Wear suitable protective clothing. Prevent contamination of skin or clothing when removing protective equipment.
Additional Advice:
Food, beverages, and tobacco products should not be carried, stored, or consumed where this material is in use.
Before eating, drinking, or smoking, wash face and hands thoroughly with soap and water.

11. TOXICOLOGICAL INFORMATION
Toxicological information for the product is found under Section 3. HAZARDS IDENTIFICATION.
Toxicological information on the regulated components of this product is as follows:
Phosphine has a 4-hour inhalation LC50 (rat) value of 57 ppm (0.079 mg/L). Inhalation overexposure is
characterized by severe pulmonary irritation, dyspnea, dizziness, lethargy, and stupor. Human evidence indicates
that pulmonary irritation and pulmonary edema are the main toxic effects of phosphine inhalation. Phosphine has
also been shown to cause central nervous system depression and gastrointestinal irritation, as well as, renal and
hepatic toxicity. Acute inhalation overexposure to high concentrations of phosphine can be fatal. In an in vivo
cytogenetic study, rats exposed to phosphine via inhalation at concentrations of 0, 6.2 and 19 ppm were examined
for chromasomal abberations in whole blood lymphocytes and bone marrow cells. A significant increase in cells with
chromasomal abberations were seen in male rats exposed to 19 ppm phosphine. No increase in cells with
chromasomal abberations were observed in the bone marrow of female rats, nor in the whole blood lymphocytes of
male or female rats.

13. DISPOSAL CONSIDERATIONS
MSDS: 0010913 Date: 08/20/2003 Page 5 of 6
VAPORPH3OS餂? Phosphine Fumigant
The information on RCRA waste classification and disposal methodology provided below applies only to the Cytec
product, as supplied. If the material has been altered or contaminated, or it has exceeded its recommended shelf life,
the guidance may be inapplicable. Hazardous waste classification under federal regulations (40 CFR Part 261 et
seq) is dependent upon whether a material is a RCRA `listed hazardous waste`or has any of the four RCRA
`hazardous waste characteristics.`Refer to 40 CFR Part 261.33 to determine if a given material to be disposed of is a
RCRA `listed hazardous waste`; information contained in Section 15 of this MSDS is not intended to indicate if the
product is a `listed hazardous waste.`RCRA Hazardous Waste Characteristics: There are four characteristics defined
in 40 CFR Section 261.21-61.24: Ignitability, Corrosivity, Reactivity, and Toxicity. To determine Ignitability, see
Section 9 of this MSDS (flash point). For Corrosivity, see Sections 9 and 14 (pH and DOT corrosivity). For
Reactivity, see Section 10 (incompatible materials). For Toxicity, see Section 2 (composition). Federal regulations
are subject to change. State and local requirements, which may differ from or be more stringent than the federal
regulations, may also apply to the classification of the material if it is to be disposed. Cytec encourages the recycle,
recovery and reuse of materials, where permitted, as an alternate to disposal as a waste. Cytec recommends that
organic materials classified as RCRA hazardous wastes be disposed of by thermal treatment or incineration at EPA
approved facilities. Cytec has provided the foregoing for information only; the person generating the waste is
responsible for determining the waste classification and disposal method.
