n-Butyl Alcohol Material Safety Data Sheet
Common Name: n-Butyl Alcohol CAS Number: 71-36-3 DOT Number: UN 1120 Date: February, 1989
HAZARD SUMMARY * n-Butyl Alcohol can affect you when breathed in and can also rapidly pass through your skin. * Exposure can cause eye irritation and headaches. Irritation of the nose and throat may also occur. Higher levels may cause you to become dizzy and lightheaded and to pass out. * Exposure can damage the liver, kidneys, hearing and the sense of balance. * n-Butyl Alcohol is a FLAMMABLE LIQUID and a FIRE HAZARD. IDENTIFICATION n-Butyl Alcohol is a colorless liquid with a strong odor. It is used as a solvent for fats, waxes, shellac, resins, gums, and varnish. REASON FOR CITATION * n-Butyl Alcohol is on the Hazardous Substance List because it is regulated by OSHA and cited by ACGIH, NFPA, DOT and EPA. * This chemical is also on the Special Health Hazard Substance List because it is FLAMMABLE. * Definitions are attached. HOW TO DETERMINE IF YOU ARE BEING EXPOSED * Exposure to hazardous substances should be routinely evaluated. This may include collecting air samples. Under OSHA 1910.20, you have a legal right to obtain copies of sampling results from your employer. If you think you are experiencing any work related health problems, see a doctor trained to recognize occupational diseases. Take this Fact Sheet with you. * ODOR THRESHOLD = 0.1 ppm. * The odor threshold only serves as a warning of exposure. Not smelling it does not mean you are not being exposed. WORKPLACE EXPOSURE LIMITS OSHA: The legal airborne permissible exposure limit (PEL) is 50 ppm not to be exceeded at any time. ACGIH: The recommended airborne exposure limit is 50 ppm which should not be exceeded at any time. * The above exposure limits are for air levels only. When skin contact also occurs, you may be overexposed, even though air levels are less than the limits listed above. WAYS OF REDUCING EXPOSURE * Where possible, enclose operations and use local exhaust ventilation at the site of chemical release. If local exhaust ventilation or enclosure is not used, respirators should be worn. * Wear protective work clothing. * Wash thoroughly immediately after exposure to n-Butyl Alcohol and at the end of the workshift. * Post hazard and warning information in the work area. In addition, as part of an ongoing education and training effort, communicate all information on the health and safety hazards of n-Butyl Alcohol to potentially exposed workers. This Fact Sheet is a summary source of information of all potential and most severe health hazards that may result from exposure. Duration of exposure, concentration of the substance and other factors will affect your susceptibility to any of the potential effects described below. ------------------------------------------ HEALTH HAZARD INFORMATION Acute Health Effects The following acute (short term) health effects may occur immediately or shortly after exposure to n-Butyl Alcohol: * Contact can irritate the skin, causing a rash or burning feeling. * Exposure can cause headaches and irritate the eyes. It can also irritate the nose and throat. Higher levels may cause you to become dizzy, lightheaded and to pass out. Chronic Health Effects The following chronic (long term) health effects can occur at some time after exposure to n-Butyl Alcohol and can last for months or years: Cancer Hazard * According to the information presently available to the New Jersey Department of Health, n-Butyl Alcohol has not been tested for its ability to cause cancer in animals. Reproductive Hazard * According to the information presently available to the New Jersey Department of Health, n-Butyl Alcohol has not been tested for its ability to adversely affect reproduction. Other Long Term Effects * Repeated contact may cause drying and cracking of the skin. * n-Butyl Alcohol can damage the hearing and sense of balance. * Exposure may damage the liver and kidneys. MEDICAL Medical Testing For those with frequent or potentially high exposure (half the TLV or greater, or significant skin contact), the following are recommended before beginning work and at regular times after that: * Liver and kidney function tests. * Hearing test (audiogram) and test for balance. Any evaluation should include a careful history of past and present symptoms with an exam. Medical tests that look for damage already done are not a substitute for controlling exposure. Request copies of your medical testing. You have a legal right to this information under OSHA 1910.20. Mixed Exposures Because more than light alcohol consumption can cause liver damage, it may increase the liver damage caused by n-Butyl Alcohol. WORKPLACE CONTROLS AND PRACTICES Unless a less toxic chemical can be substituted for a hazardous substance, ENGINEERING CONTROLS are the most effective way of reducing exposure. The best protection is to enclose operations and/or provide local exhaust ventilation at the site of chemical release. Isolating operations can also reduce exposure. Using respirators or protective equipment is less effective than the controls mentioned above, but is sometimes necessary. In evaluating the controls present in your workplace, consider: (1) how hazardous the substance is, (2) how much of the substance is released into the workplace and (3) whether harmful skin or eye contact could occur. Special controls should be in place for highly toxic chemicals or when significant skin, eye, or breathing exposures are possible. In addition, the following controls are recommended: * Where possible, automatically pump liquid n-Butyl Alcohol from drums or other storage containers to process containers. to make sure that an explosive concentration does not exist. Good WORK PRACTICES can help to reduce hazardous exposures. The following work practices are recommended: * Workers whose clothing has been contaminated by n-Butyl Alcohol should change into clean clothing promptly. * Contaminated work clothes should be laundered by individuals who have been informed of the hazards of exposure to n-Butyl Alcohol. * On skin contact with n-Butyl Alcohol, immediately wash or shower to remove the chemical. At the end of the work shift, wash any areas of the body that may have contacted n-Butyl Alcohol, whether or not known skin contact has occurred. * Do not eat, smoke, or drink where n-Butyl Alcohol is handled, processed, or stored, since the chemical can be swallowed. Wash hands carefully before eating or smoking. PERSONAL PROTECTIVE EQUIPMENT WORKPLACE CONTROLS ARE BETTER THAN PERSONAL PROTECTIVE EQUIPMENT. However, for some jobs (such as outside work, confined space entry, jobs done only once in a while, or jobs done while workplace controls are being installed), personal protective equipment may be appropriate. The following recommendations are only guidelines and may not apply to every situation. Clothing * Avoid skin contact with n-Butyl Alcohol. Wear solvent resistant gloves and clothing. Safety equipment suppliers/ manufacturers can provide recommendations on the most protective glove/ clothing material for your operation. * All protective clothing (suits, gloves, footwear, headgear) should be clean, available each day, and put on before work. * ACGIH recommends neoprene, nitrile, or polyvinyl chloride as good to excellent protective materials. Eye Protection * Wear splash proof chemical goggles and face shield when working with liquid n-Butyl Alcohol, unless full facepiece respiratory protection is worn. Respiratory Protection IMPROPER USE OF RESPIRATORS IS DANGEROUS. Such equipment should only be used if the employer has a written program that takes into account workplace conditions, requirements for worker training, respirator fit testing and medical exams, as described in OSHA 1910.134. * Where the potential exists for exposures over 50 ppm, use a MSHA/NIOSH approved full facepiece respirator with an organic vapor cartridge/canister. Increased protection is obtained from full facepiece powered air purifying respirators. * If while wearing a filter, cartridge or canister respirator, you can smell, taste, or otherwise detect n-Butyl Alcohol, or in the case of a full facepiece respirator you experience eye irritation, leave the area immediately. Check to make sure the respirator to face seal is still good. If it is, replace the filter, cartridge, or canister. If the seal is no longer good, you may need a new respirator. * Be sure to consider all potential exposures in your workplace. You may need a combination of filters, prefilters, cartridges, or canisters, to protect against different forms of a chemical (such as vapor and mist) or against a mixture of chemicals. * Where the potential for high exposures exists, use a MSHA/NIOSH approved supplied air respirator with a full facepiece operated in the positive pressure mode or with a full facepiece, hood, or helmet in the continuous flow mode. * Exposure to 8,000 ppm is immediately dangerous to life and health. If the possibility of exposures above 8,000 ppm exists, use a MSHA/NIOSH approved self contained breathing apparatus with a full facepiece operated in continuous flow or other positive pressure mode. HANDLING AND STORAGE * Prior to working with n-Butyl Alcohol you should be trained on its proper handling and storage. * n-Butyl Alcohol is not compatible with ACID ANHYDRIDES, ACID CHLORIDES, OXIDIZERS (such as PERCHLORATES, PEROXIDES, PERMANGANATES, CHLORATES and NITRATES), REDUCING AGENTS, COPPER and COPPER ALLOYS. * Store in tightly closed containers in a cool, well ventilated area away from HEAT. * Sources of ignition such as smoking and open flames are prohibited where n-Butyl Alcohol is used, handled, or stored in a manner that could create a potential fire or explosion hazard. * Metal containers used in the transfer of 5 gallons or more of n-Butyl Alcohol should be grounded and bonded. Drums must be equipped with self closing valves, pressure vacuum bungs, and flame arresters. * Use only non sparking tools and equipment, especially when opening and closing containers of n-Butyl Alcohol.

It is used in the coatings industry for the production of lacquers and latexes, as an intermediate in the manufacture of certain plastics, as a solvent for oils, drugs, and perfumes, as an ingredient in perfumes and flavors, and in formulating automobile brake fluids. It may enter the environment from industrial or municipal waste treatment plant discharges, or spills. ACUTE (SHORT-TERM) ECOLOGICAL EFFECTS Acute toxic effects may include the death of animals, birds, or fish, and death or low growth rate in plants. Acute effects are seen two to four days after animals or plants come in contact with a toxic chemical substance. n-Butyl Alcohol has slight acute toxicity to aquatic life and birds. It has caused various adverse effects in agricultural and ornamental crops. Insufficient data are available to evaluate or predict the short-term effects of n-Butyl Alcohol to land animals. CHRONIC (LONG-TERM) ECOLOGICAL EFFECTS Chronic toxic effects may include shortened lifespan, reproductive problems, lower fertility, and changes in appearance or behavior. Chronic effects can be seen long after first exposure(s) to a toxic chemical. n-Butyl Alcohol has slight chronic toxicity to aquatic life. Insufficient data are available to evaluate or predict the long- term effects of n-Butyl Alcohol to plants, birds, or land animals. WATER SOLUBILITY n-Butyl Alcohol is highly soluble in water. Concentrations of 1,000 milligrams and more will mix with a liter of water. DISTRIBUTION AND PERSISTENCE IN THE ENVIRONMENT n-Butyl Alcohol is slightly persistent in water, with a half-life of between 2 to 20 days. The half-life of a pollutant is the amount of time it takes for one-half of the chemical to be degraded. About 76.5% of n-Butyl Alcohol will eventually end up in water; the rest will end up in the air. BIOACCUMULATION IN AQUATIC ORGANISMS Some substances increase in concentration, or bioaccumulate, in living organisms as they breathe contaminated air, drink contaminated water, or eat contaminated food. These chemicals can become concentrated in the tissues and internal organs of animals and humans. The concentration of n-Butyl Alcohol found in fish tissues is expected to be about the same as the average concentration of n- Butyl Alcohol in the water from which the fish was taken.
