SUBSTANCE NAME VAPORPH 3OS 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.

Flash point: Flammability: LogPow: pyrophoric extremely flammable (catches fire if exposed to air) NA 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 Mutagenicity Carcinogenicity Reproductive Toxicity 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. 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. ENVIRONMENTAL EFFECTS EFFECT ASSESSMENT Aquatic Toxicity FATE AND BEHAVIOR Biodegradation Bioaccumulation potential PBT/vPvB conclusion RESULT Phosphine is highly toxic to aquatic life. 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). EXPOSURE Page 2
Human Health VAPORPH 3OS 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 3OS. 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. Page 3
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 3OS 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 3OS Phosphine Fumigant is used solely for the fumigation of agricultural post-harvest products or storage structures. Before using VAPORPH 3OS, 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.
