Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Wash away remainder with plenty of water.
ACCIDENTAL RELEASE MEASURES. Personal precautions, protective equipment and emergency procedures: Use personal protective equipment. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. Evacuate personnel to safe areas. Beware of vapours accumulating to form explosive concentrations. Vapours can accumulate in low areas.; Environmental precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains.; Methods and materials for containment and cleaning up: Contain spillage, and then collect with an electrically protected vacuum cleaner or by wet-brushing and place in container for disposal according to local regulations.
Waste water treatment: Activated carbon: absorbability: 0.107 g/g C, 53% reduction, influent: 1,000 mg/L, effl: 466 mg/L; Reverse osmosis: 41.3% rejection from a 0.01 M soln; Stabilization pond design: toxicity correction factor: 2.0 at 4,000 mg/L influent; Anaerobic lagoon: 22 lb Chemical Oxygen Demand (COD)/day/1,000 cu ft: influent: 170 mg/L, effluent: 75 mg/L; 48 lb COD/day/1,000 cu ft: influent: 170 mg/L, effluent: 80 mg/L
Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste numbers U031 and F003, must conform with USEPA regulations in storage, transportation, treatment and disposal of waste.
SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.
Product: Burn in a chemical incinerator equipped with an afterburner and scrubber but exert extra care in igniting as this material is highly flammable. Offer surplus and non-recyclable solutions to a licensed disposal company. Contact a licensed professional waste disposal service to dispose of this material.; Contaminated packaging: Dispose of as unused product.
Incineration: Incinerate by atomizing into a suitable combustion chamber.
For more Disposal Methods (Complete) data for N-BUTYL ALCOHOL (6 total), please visit the HSDB record page.
SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits 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.
SRP: Contaminated protective clothing should be segregated in a manner such that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. The completeness of the cleaning procedures should be considered before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at the end of shift, but should remain at employee's place of work for cleaning.
Employees should wash immediately with soap when skin is wet or contaminated. Remove nonimpervious clothing immediately if wet or contaminated. Provide emergency showers and eyewash.
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 butyl alcohol should be placed in closed containers for storage until it can be discarded or until provision is made for the removal of butyl alcohol from the clothing. If the clothing is to be laundered or otherwise cleaned to remove the butyl alcohol, the person performing the operation should be informed of butyl alcohol's hazardous properties. Any clothing which becomes wet with liquid butyl alcohol should be removed immediately and not reworn until the butyl alcohol is removed from the clothing.

IDENTIFICATION: n-Butyl Alcohol (BA) is an aliphatic alcohol with a rancid sweet odor, that is liquid at room temperature. n-Butyl Alcohol has numerous applications in the plastics and textile sector. It is ofen used as an industrial intermediate, converted into derivatives including butyl acetate and other butyl esters, which serve as solvents or monomer components in the production of artificial leather, textiles, safety glass, rubber cement, shellac, raincoats, photographic films, or perfumes. n-Butyl Alcohol can also be used directly as a solvent for paints, lacquers and varnishes, natural and synthetic resins, gums, vegetable oils, dyes and alkaloids. It is historically used as a solvent in nail care cosmetic products, and is also being used at low concentrations in eye makeup, personal hygiene, and shaving cosmetic products. n-Butyl Alcohol has been generally recognized as safe for use as a flavoring substance in food and appears on the 1982 Food and Drug Administration (FDA) list of inactive ingredients for approved prescription drug products. HUMAN EXPOSURE AND TOXICITY: Human exposure to n-butyl alcohol may occur in the workplace during manufacture and industrial/commercial use, and during consumer use of products containing n-butyl alcohol. Workers complained of ocular irritation, disagreeable odor, slight headache and vertigo, slight irritation of nose and throat, and dermatitis of the fingers and hands when the air concentration of n-Butyl Alcohol was greater than 50 ppm. Short term inhalation of n-butanol also produces a variety of CNS effects, including giddiness, ataxia, confusion, delirium, and possible coma. In high concentration in the air it can cause transient mild edema of conjunctiva of the eye, and a slightly reduced erythrocyte count. Inhalation toxicity studies in humans demonstrate sensory irritation of the upper respiratory tract, but only at levels above 3000 mg/cu m. n-Butyl Alcohol ingestion may result in vomiting, abdominal pain, headache, drowsiness and unconsciousness. Nail enamel containing 3% n-Butyl Alcohol resulted in no reactions. ANIMAL STUDIES: Animal studies demonstrate intoxication, restlessness, ataxia, prostration, and narcosis with exposure to n-butyl alcohol. High concentrations of n-Butyl Alcohol vapors can be fatal. Ocular irritation was observed for n-Butyl alcohol at 0.005 mL of a 40% solution. The behavioral no-effect dose for n-Butyl Alcohol injected subcutaneously (s.c.) was 120 mg/kg. Fetotoxicity has been demonstrated, but only at maternally toxic levels (1000 mg/kg). No significant behavioral or neurochemical effects were seen in offspring following either maternal or paternal exposure to 3000 or 6000 ppm. n-Butyl Alcohol was not mutagenic in the Ames tests and did not have any chromosome-damaging effects in a mouse micronucleus test. ECOTOXICITY STUDIES: BA exhibits low toxicity to fish, amphibians and aquatic invertebrates, plants, algae, bacteria and protozoans. However, some algal species are sensitive to BA. Acute toxicity to aquatic life may occur at concentrations greater than 500 mg/L.

The effects of combined exposure to m-xylene and n-butyl alcohol on rotarod performance and motor activity in rats and respiratory rate in mice were investigated in the condition of an acute inhalation experiment. Rotarod performance and motor activity were tested in rats exposed to various concentrations of m-xylene, n-butyl alcohol and their mixture consisting of 50 Vol-% m-xylene and 50 Vol-% n-butyl alcohol immediately after termination of a 4-hour exposure period. The respiratory rate in mice was recorded in short 6 min duration exposures to individual solvents and their 50:50 Vol-% mixture. Both solvents and mixtures caused concentration-dependent disturbances of rotarod performance in rats. The medial effective concentration (EC50) for the effect amounted 6530 ppm, 1980 ppm and 3080 ppm for n-butyl alcohol, m-xylene and their mixture, respectively. Both solvents and their mixture changed the spontaneous motor activity in the rat. Because of a two-phase effect, the concentration-dependence of the observed changes could not be defined. The evaluation of the combined effect in motor activity test was carried out by comparing experimental values with expected ones assuming the summation of individual solvent effects. The tested solvents resulted in a concentration-dependent decrease in respiratory rate in mice. The concentration which decreased the respiratory rate to 50% (RD50) was 3010 ppm, 1360 ppm and 3140 ppm for n-butyl alcohol, m-xylene and their mixture, respectively...
The activity of partially purified human erythrocyte acid phosphatase (eapase) was enhanced 4-fold by n-butanol. The extent of human prostatic acid phosphatase (papase) activation by n-propanol was lower than that of eapase. Eapase & papase activation by aliphatic alcohols, including n-butanol was noncompetitive.
Potentiates bactericidal effects of alcohol, ethyl & alcohol, propyl.
Pretreatment with n-butanol (10 mmol/kg i.p.) 30 minutes before alloxan (100 mg/kg) protects mice from the permanent hyperglycemic effects (measured at 72 hours) of the diabetogenic agent. This dose of n-butanol caused an elevation of serum glucose at 30 minutes, the time of alloxan administration. Since glucose administration can protect animals from alloxan, the possibility that alcohol-induced hyperglycemia protected mice from alloxan was investigated. Mannoheptulose, an antagonist of glucose action at the pancreatic beta-cell, when given 24 minutes after n-butanol and 6 minutes before alloxan, eliminated the alcohol-induced protection. Fasted mice did not exhibit n-butanol-induced hyperglycemia at 30 minutes and alloxan given at that time produced diabetes. No protection was observed in fed animals when n-butanol was given 5 minutes before alloxan. The high serum levels of butanol and normal serum glucose which were observed at 5 minutes after alcohol administration indicated that the lack of protection was not due to a lack of circulating alcohol but resulted from an absence of hyperglycemia. The results indicate that pretreatment with n-butanol protects mice from alloxan-induced diabetes by the indirect mechanism of producing hyperglycemia at the time of alloxan administration.

/HUMAN EXPOSURE STUDIES/ In this study, /researchers/ investigated the time course effect of sensory eye irritation in 16 subjects exposed (i.e., eye only) to n-butanol and 1-octene. Half the subjects were exposed to n-butanol, and the remaining subjects were exposed to 1-octene. Each subject was studied on 5 different days; during each day each subject was exposed in three runs (i.e., run 1, run 2, and run 3) to a constant concentration of either n-butanol or 1-octene. /They/ performed run 1 and run 3, both of which lasted 15 min each, to evaluate persistence in "sensitization." /Researchers/ performed run 2, which lasted 60 min, to study the time course of sensory irritation. Ratings of ocular irritation intensity were obtained continuously during all three runs. The exposure concentrations for n-butanol were 0 mg/cu m, 300 mg/cu m, 900 mg/cu m, and 3 000 mg/cu m, and the exposure concentrations for 1-octene were 0 mg/cu m, 6 000 mg/cu m, 10 400 mg/cu m, and 18 000 mg/cu m. During run 2, /researchers/ observed a slight increase in perceived eye irritation intensity for the lower concentrations of 1-octene and for all exposure concentrations of n-butanol. However, the threshold for irritation was clearly exceeded for only the 1-octene 10 400-mg/cu m and 18 000-mg/cu m exposures. During these two exposures, the response increased 10-fold following 20-40 min of exposure during run 2, after which the response remained constant. /The authors/ investigated the existence of persistence in "sensitization" by comparing intensity of responses between run 1 and run 3. Persistence in "sensitization" was apparent for only the 1-octene exposure.
/HUMAN EXPOSURE STUDIES/ ...Clinical testing of n-Butyl Alcohol for nonimmunological contact urticaria was negative in 105 subjects. Repeat-insult patch test (RIPT) studies of nail colors and enamels containing 3% n-Butyl Alcohol in one study produced reactions on challenge, but further study linked significant positive reactions to another solvent. In other RIPT studies, only minimal reactions were reported. A photopatch test demonstrated that a nail enamel containing 3% n-Butyl Alcohol resulted in no reactions.
/HUMAN EXPOSURE STUDIES/ Twelve subjects were exposed to 300 or 600 mg/cu M of n-butyl alcohol in inspired air during rest and during exercise on a bicycle ergometer. Exposure lasted 2 hr. The results were puzzling in view of the high blood/air partition coefficient for butyl alcohol. The arterial blood concentration was low. The concentration in the last part of the expired air, i.e., the ""alveolar'' concentration, was low. The quotient of ""alveolar'' concentration X 100/inspired concentration was low in relation to the low percentage uptake. However the high solubility of butyl alcohol in water may explain the results. Butyl alcohol was probably partially taken up in the water of the dead space mucous membranes during inspiration. It was then partially released from the membranes. Therefore the concentration of butyl alcohol in the last part of expiration was probably not the same as the concentration in the alveolar air.
/HUMAN EXPOSURE STUDIES/ Volunteers exposed to n-butanol for 2 hr at air concn of 100 and 200 ppm developed blood concn that never exceeded 1.0 mg/L, whether at rest or during excercise. Exposure to an air concn of 50 ppm for 2 hr resulted in blood levels less than 0.08 mg/l.

n-Butyl alcohol's production and use as a solvent in surface coatings, varnishes, resins, waxes and gums and in the manufacture of various butyl compounds may result in its release to the environment through various waste streams. n-Butyl alcohol occurs as a product of fermentation of carbohydrates in alcoholic beverages and has been detected in the volatiles of various foods. If released to air, a vapor pressure of 7 mm Hg at 25 °C indicates n-butyl alcohol will exist solely as a vapor in the ambient atmosphere. Vapor-phase n-butyl alcohol will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 45 hours. n-Butyl alcohol does not contain chromophores that absorb at wavelengths >290 nm and, therefore, is not expected to be susceptible to direct photolysis by sunlight. If released to soil, n-butyl alcohol is expected to have very high mobility based upon a Koc of 3.2. Volatilization from moist soil surfaces is expected to be an important fate process based upon a Henry's Law constant of 8.81X10-6 atm-cu m/mole. n-Butyl alcohol is expected to volatilize from dry soil surfaces based upon its vapor pressure. The biodegradation half-life of n-butyl alcohol in a sub-surface soil was approximately 7 days. n-Butyl alcohol biodegrades rapidly in screening tests using a sewage or activated sludge inoculum and is considered readily biodegradable. If released into water, n-butyl alcohol is not expected to adsorb to suspended solids and sediment in water based upon the estimated Koc. Volatilization from water surfaces is expected to be an important environmental fate process based upon this compound's Henry's Law constant. Estimated volatilization half-lives for a model river and model lake are 3.7 and 29 days, respectively. An estimated BCF of 3 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions. In a river die-away test, n-butyl alcohol achieved 33% of its theoretical BOD in 5 days, suggesting biodegradation will be an important fate process in water. Occupational exposure may occur through inhalation and dermal contact with this compound at workplaces where n-butyl alcohol is produced or used. Monitoring and use data indicate that the general population is exposed to n-butyl alcohol through the ingestion of foods that contain this compound, inhalation of ambient air and exposure to consumer products that contain n-butyl alcohol.

Volatilization from water surfaces is expected to be an important fate process(3) based upon a Henry's Law constant of 8.81X10-6 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 3.7 and 29, days respectively(SRC). According to a classification scheme(5), an estimated BCF of 3(SRC), from its log Kow(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low.

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), n-butyl alcohol, which has a vapor pressure of 7 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase n-butyl alcohol is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC).

AEROBIC: n-Butyl alcohol biodegrades rapidly in screening tests using a sewage or activated sludge inoculum and is considered readily biodegradable(1). n-Butyl alcohol reached 66% of its theoretical BOD in a sewage sludge during a 5 day incubation period(2) and 33% of its theoretical BOD using an inoculum from polluted surface water(3). The first-order rate constant for the degradation of n-butyl alcohol in soils was reported as 2X10-6 sec-1(4); this corresponds to a half-life of approximately 4 days(SRC). The first-order biodegradation rate constant of n-butyl alcohol in an activated sludge inoculum was reported as 9.59X10-3 per hour(5); this corresponds to a half-life of about 3 days(SRC). The biodegradation half-life of n-butyl alcohol in a sub-surface soil from Blacksburg, VA was approximately 7 days(6). The biodegradation half-life of n-butyl alcohol in a basic sandy silt loam from Texas was reported as 1 day and the half-life of n-butyl alcohol in an acidic sandy loam from Mississippi was reported as 8.5 days(7). A 20 day BOD (Biochemical Oxygen Demand) test was conducted using unacclimated settled domestic wastewater as the microbial seed (3 mL/BOD bottle)(1); the results showed a BOD5 of 68% ThOD (percent of theoretical oxygen demand), a BOD10 of 87% ThOD, a BOD15 of 92% ThOD, and a BOD20 of 92% ThOD(1). n-Butyl alcohol, present at 100 mg/L, reached >60% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(8).
AEROBIC: Thirty-eight process wastewaters and 37 organic substances identified in the wastewater of the Kashima (Japan) petrochemical complex were subjected to the activated sludge degradability test. The test used the activated sludge of the Fukashiba (Japan) industrial wastewater treatment plant, which was acclimatized to the wastewater and organic substances. Water in the test container was sampled during aeration at 0 hr and 24 hrs later. After 1 day of acclimation, 100 mg/l of n-butyl alcohol resulted in a chemical oxygen demand of 82% and 93% total organic carbon(1).
The rate constant for the vapor-phase reaction of n-butyl alcohol with photochemically-produced hydroxyl radicals has been measured as 8.5X10-12 cu cm/molecule-sec at 25 °C(1). This corresponds to an atmospheric half-life of about 45 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(2). The rate constant for the reaction of hydroxyl radicals in aqueous solutions is 4.2X10+9 L/mol-sec(3); this corresponds to an aquatic half-life of 191 days at an aquatic concentration of 1X10-17 hydroxyl radicals per liter(4). n-Butyl alcohol is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(5). n-Butyl alcohol does not contain chromophores that absorb at wavelengths >290 nm(5) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC).
An estimated BCF of 3 was calculated in fish for n-butyl alcohol(SRC), using a log Kow of 0.88(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
The measured Koc of n-butyl alcohol is reported as 3.2(1). According to a classification scheme(2), this Koc value suggests that n-butyl alcohol is expected to have very high mobility in soil(SRC).
The Henry's Law constant for n-butyl alcohol is 8.81X10-6 atm-cu m/mole at 25 °C(1). This Henry's Law constant indicates that n-butanol is expected to volatilize from water surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 3.7 days(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 29 days(SRC). n-Butyl alcohol's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). n-Butyl alcohol is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 7 mm Hg(3).
