| Erste Hilfe | EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.INHALATION: IMMEDIATELY leave the contaminated areatake deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be usedif not available, use a level of protection greater than or equal to that advised under Protective Clothing.INGESTION: DO NOT INDUCE VOMITING. Corrosive chemicals will destroy the membranes of the mouth, throat, and esophagus and volatile chemicals have a high risk of being aspirated into the victim's lungs during vomiting. Thus, the risk of increasing the medical problems by inducing vomiting of a volatile corrosive chemical is very high. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. IMMEDIATELY transport the victim to a hospital. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)General First Aid:· Call 911 or emergency medical service.· Ensure that medical personnel are aware of the material(s) involved, take precautions to protect themselves and avoid contamination.· Move victim to fresh air if it can be done safely.· Administer oxygen if breathing is difficult.· If victim is not breathing:-- DO NOT perform mouth-to-mouth resuscitationthe victim may have ingested or inhaled the substance.-- If equipped and pulse detected, wash face and mouth, then give artificial respiration using a proper respiratory medical device (bag-valve mask, pocket mask equipped with a one-way valve or other device).-- If no pulse detected or no respiratory medical device available, provide continuous compressions. Conduct a pulse check every two minutes or monitor for any signs of spontaneous respirations.· Remove and isolate contaminated clothing and shoes.· For minor skin contact, avoid spreading material on unaffected skin.· In case of contact with substance, remove immediately by flushing skin or eyes with running water for at least 20 minutes.· For severe burns, immediate medical attention is required.· Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed.· Keep victim calm and warm.· Keep victim under observation.· For further assistance, contact your local Poison Control Center.· Note: Basic Life Support (BLS) and Advanced Life Support (ALS) should be done by trained professionals.Specific First Aid:· Wash skin with soap and water. |

| Umweltverhalten | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 72(SRC), determined from a log Kow of 0.88(2) and a regression-derived equation(3), indicates that butyraldehyde is expected to have high mobility in soil(SRC). Volatilization of butyraldehyde from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 1.15X10-4 atm-cu m/mole(4). Butyraldehyde is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 111 mm Hg(5). A theoretical BOD of 100% in 2 weeks using an activated sludge in the Japanese MITI test(6), suggests that biodegradation is an important environmental fate process in soil(SRC). Under anaerobic conditions, butanal underwent 99% degradation (7 day lag period) using the Hungate serum bottle technique(7).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 72(SRC), determined from a log Kow of 0.88(2) and a regression-derived equation(3), indicates that butyraldehyde is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon a Henry's Law constant of 1.15X10-4 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 9 hrs and 5 days, respectively(SRC). The rate constant for the reaction between photochemically produced hydroxyl radicals in water and butyraldehyde is 3.9X10+9 L/mole-sec(5)at an aquatic concentration of 1X10-17 mole/L of hydroxyl radicals(6), the half-life would be about 206 days(SRC). According to a classification scheme(7), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(8), suggests the potential for bioconcentration in aquatic organisms is low(SRC). A theoretical BOD of 100% in 2 weeks using an activated sludge in the Japanese MITI test(9), suggests that biodegradation is an important environmental fate process in water(SRC).Under anaerobic conditions, butanal underwent 99% degradation (7 day lag period) using the Hungate serum bottle technique(10).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), butyraldehyde, which has a vapor pressure of 111 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase butyraldehyde is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be 16 hrs(SRC), calculated from its rate constant of 2.35X10-11 cu cm/molecule-sec at 25 °C(3). The rate constant for the vapor-phase reaction of butyraldehyde with nitrate radical has been experimentally determined to be 1.15X10-14 cu cm/sec(4), which corresponds to an atmospheric half-life of about 2.9 days(SRC). Butyraldehyde absorbs solar radiation (> 290 nm)direct photooxidation products include carbon monoxide, ethene, ethanal and carbon dioxide(5). |
