Product Safety Assessment: DOW m Methyl Isobutyl Carbinol preferred. Use of a direct water stream may spread the fire. The public should be warned of any downwind vapor explosion hazards. Vapors are heavier than air and may travel a long distance and accumulate in low -lying areas. Keep vapors out of sewers. Firefighters should wear positive - pressure, self- contained breathing apparatus (SCBA) with an approved full -face mask and protective firefighting clothing. See Physical Hazard Information. For more information, see the relevant Safety Data Sheet. Back to top Health Information 14,15 Eye and Skin Contact— May cause moderate eye irritation or moderate corneal injury. Exposure to methyl isobutyl carbinol vapor may cause eye irritation, mild discomfort, and redness. Prolonged skin contact may cause slight irritation and local redness or drying and flaking of the skin, but is unlikely to result in absorption of harmful amounts. Inhalation — Prolonged, excessive exposure to methyl isobutyl carbinol may cause adverse effects. Excessive exposure may cause irritation to the upper respiratory tract and lungs. Symptoms of excessive vapor exposure may be anesthetic or narcotic effects, dizziness, and drowsiness. Ingestion — Methyl isobutyl carbinol has low toxicity if swallowed. Small amounts swallowed incidental to normal handling operations are not likely to cause injury; however, swallowing larger amounts may cause injury. Excessive exposure — Excessive exposure may cause anesthetic or narcotic effects, dizziness, and drowsiness. Kidney toxicity has been reported in animal studies. Other— Methyl isobutyl carbinol is unlikely to be mutagenic in humans. Based on the available data from animal studies, this material is not expected to be a human reproductive or developmental toxicant. For more information, see the relevant Safety Data Sheet Back to top Environmental Information's" DOWTM methyl isobutyl carbinol is moderately volatile and moderately soluble in water. As a result when introduced to water, the chemical will have a tendency to remain in water. It has low potential to bind to soil or sediment. DOW methyl isobutyl carbinol is unlikely to persist in the environment. The compound is readily biodegradable, which suggests the chemical will be rapidly and completely removed from water and soil environments, including biological wastewater treatment plants. DOW methyl isobutyl carbinol is not likely to accumulate in the food chain (bioconcentration potential is low) and is practically nontoxic to fish and other aquatic organisms on an acute basis.
