Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. (ERG, 2016)

Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. For electric vehicles or equipment, ERG Guide 147 (lithium ion batteries) or ERG Guide 138 (sodium batteries) should also be consulted. (ERG, 2016)

Wear self-contained breathing apparatus for firefighting if necessary.

Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.

Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.

Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.

Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Store the container tightly closed in a dry, cool and well-ventilated place. Store apart from foodstuff containers or incompatible materials.

Thermal hazards

no data available

Extremely stable to heat, light, and atmospheric oxygen.

Not autoflammable but tech. will explode in a dust cloud if ignited.FENBUTATIN OXIDE is in the family of tin compounds widely used as stabilizers for plastics, additives to paint(as antifouling agents). Some have catalytic properties. Examples include butyl tin, dibutyl tin oxide. Their main hazard is associated with their high toxicity, in skin adsorption or inhalation.

no data available

Water causes conversion of fenbutatin oxide to tris(2-methyl-2-phenylpropyl)tin hydroxide which is reconverted to the parent compound slowly at room temperature and rapidly at 98 deg C.

When heated to decomposition it emits acrid smoke and irritating fumes.

AEROBIC: Fenbutatin oxide was relative stable in three soils(1). After 12 months under aerobic conditions in loamy sand, silty clay loam, and sandy clay loam soils, 80.0%, 76.5%, and 79.7% of the applied radioactivity was removed as undegraded fenbutatin oxide, respectively(1).

Fenbutatin oxide does accumulate in fish tissues, as expected from its Kow (ie, 1.4X10+5)(1). Bioconcentration factors of 340 to 500 for muscle tissue, 1,110 to 1,600 for visceral tissue, 450 to 640 for the remaining carcass and 490 to 730 for whole fish were determined for bluegill sunfish exposed to fenbutatin oxide at 0.00013 mg/l or 0.00068 mg/l(1). However, the lack of a plateau in the concn of fenbutatin oxide in the various tissues could indicate that the actual BCF's are higher(1). Depuration of the accumulated residues was somewhat limited, with only 51-75% of the accumulated residues being eliminated by day 14 of the depuration period(1). According to a classification scheme(2), BCF values of 490 to 730(1) suggest bioconcentration in aquatic organisms is high(SRC).

Unaged fenbutatin oxide was immobile in columns of two loamy sand soils, a silty clay soil, and a sandy clay soil(1). More than 90% of the Sn-119 residues did not move out of the treated layer(1). Fenbutatin oxide residues aged for 30 days were slightly mobile in a column of loamy sand soil. SN-119 residues were distributed throughout the column (92% in the upper 6 cm) and 1% were recovered in the leachate(1). Sn-119 in fenbutatin oxide comprised 98% of the recovered extractable radioactivity in the soil(1). Fenbutatin oxide with a 0.2% surfactant at 0.1, 1.0, and 10 ug/ml, was slightly mobile to immobile (Kads: 6.9 to 3,587) in two loamy sand soils, a silty clay soil and a sandy clay loam soil(1). Less than 5% of the adsorbed pesticide desorbed from the soil(1). Fenbutatin oxide with a 1% acetone co-solvent at 5, 1 ,0.2 and 0.04 mg/ml was immobile (Kd: 1,282 to 2,333) in a loamy sand, sandy loam, and silty loam soil(1). Less than 0.5% of the adsorbed pesticide desorbed from the soil(1).
