| Preventive Measures | SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.VENTILATION CONTROL: THE BASIC VENTILATION METHODS ARE LOCAL EXHAUST VENTILATION AND DILUTION OR GENERAL VENTILATION. ... SUBSTITUTION OF LESS IRRITATING SUBSTANCES ... REDESIGN OF OPERATIONS ... PREVENT CONTACT, PROVISION OF A PHYSICAL BARRIER AGAINST CONTACT, PROPER WASHING FACILITIES, WORK CLOTHING AND STORAGE FACILITIES, PROTECTIVE CLOTHING, AND BARRIER CREAMS. MEDICAL CONTROL ...Respirators may be used when engineering and work practice controls are not technically feasible, when such controls are in the process of being installed, or when they fail and need to be supplemented. Respirators may also be used for operations which require entry into tanks or closed vessels, and in emergency situations. ... Clothing wet with liquid sec-butyl alcohol should be placed in closed containers for storage until it can be discarded or until provision is made for the removal of sec-butyl alcohol from the clothing. If the clothing is to be laundered or otherwise cleaned to remove the sec-butyl alcohol, the person performing the operation should be informed of sec-butyl alcohol's hazardous properties. Any clothing which becomes wet with liquid sec-butyl alcohol should be removed immediately and not reworn until the sec-butyl alcohol is removed from the clothing.SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.For more Preventive Measures (Complete) data for SEC-BUTYL ALCOHOL (9 total), please visit the HSDB record page. |

| Umweltverhalten | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 50(SRC), determined from a log Kow of 0.61(2) and a regression-derived equation(3), indicates that sec-butyl alcohol is expected to have high mobility in soil(SRC). Volatilization of sec-butyl alcohol from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 9.06X10-6 atm-cu m/mole(4). The potential for volatilization of sec-butyl alcohol from dry soil surfaces may exist based upon a vapor pressure of 18.3 mm Hg(5). Biodegradation is expected to be an important fate process for this compound in soil surfaces(SRC). sec-Butyl alcohol achieved 44.2 and 72.3% of its theoretical BOD after 10 and 20 day incubation periods, respectively using a domestic sewage sludge inoculum(6).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 50(SRC), determined from a log Kow of 0.61(2) and a regression- derived equation(3), indicates that sec-butyl alcohol is not expected to adsorb to suspended solids and sediment in water(SRC). Volatilization from water surfaces is expected to be an important fate process(3) based upon a Henry's Law constant of 9.06X10-6 atm-cu m/mole(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 2 and 29, days respectively(SRC). According to a classification scheme(5), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is low. In a river die-away test, sec-butyl alcohol achieved 55% of its theoretical BOD in 5 days(7), suggesting biodegradation will be an important fate process(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), sec-butyl alcohol, which has a vapor pressure of 18.3 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase sec-butyl alcohol is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC). The half-life for the reaction in air with hydroxyl radicals is estimated to be 40 hours(SRC), calculated from its rate constant of 9.6X10-12 cu cm/molecule-sec at 25 °C(3). |

| Effluent Concentrations | In a comprehensive survey of wastewater from 4,000 industrial and publicly owned treatment works (POTWs) sponsored by the Effluent Guidelines Division of the U.S. EPA, sec-Butyl alcohol was identified in discharges of the following industrial category (positive occurrences, median concn in ppb): leather tanning (146.7), petroleum refining (1149.3), paint and ink (1324.7), organics and plastics (235.4), pesticides manufacture (136.2), pharmaceuticals (14.6), foundries (141.0), electronics (119.9), mechanical products (390.6), publicly owned treatment works (312.4)(1). The highest effluent concn was 920.1 ppb in the mechanical products industry(1). sec-Butyl alcohol was found in landfill leachate from 1 of 5 sites in Connecticut(2). The concentration of sec-butyl alcohol in this leachate ranged from 6.2 to 14.9 ppm(2). Trench leachate from the Maxey Flats, KY and West Valley, NY disposal sites also contained sec-butyl alcohol(3). sec-Butyl alcohol was identified, not quantified, in the volatile emissions of furniture coatings(4). sec-Butyl alcohol was detected at concns ranging from 1 to 272 mg/cu m in landfill gas from 7 waste disposal sites in the United Kingdom(5). sec-Butyl alcohol was identified, not quantified, in the volatile emissions of common garden waste(6). |

| Soil Adsorption/Mobility | The Koc of sec-butyl alcohol is estimated as 50(SRC), using a log Kow of 0.61(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that sec-butyl alcohol is expected to have high mobility in soil(SRC). |

| TSCA-Anforderungen | Section 8(a) of TSCA requires manufacturers of this chemical substance to report preliminary assessment information concerned with production, use, and exposure to EPA as cited in the preamble in 51 FR 41329.Pursuant to section 8(d) of TSCA, EPA promulgated a model Health and Safety Data Reporting Rule. The section 8(d) model rule requires manufacturers, importers, and processors of listed chemical substances and mixtures to submit to EPA copies and lists of unpublished health and safety studies. s-Butyl alcohol is included on this list. |

| Luftstandards | This action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. s-Butyl alcohol is produced, as an intermediate or a final product, by process units covered under this subpart. |
