  • First Aid: 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. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.; INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, immediately 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 used; if not avail Source: CAMEO Chemicals

  • NFPA Health Rating: 0 - Materials that, under emergency conditions, would offer no hazard beyond that of ordinary combustible materials. Source: Hazardous Substances Data Bank (HSDB)
  • NFPA Fire Rating: 1 - Materials that must be preheated before ignition can occur. Materials require considerable preheating, under all ambient temperature conditions, before ignition and combustion can occur. Source: Hazardous Substances Data Bank (HSDB)
  • NFPA Instability Rating: 0 - Materials that in themselves are normally stable, even under fire conditions. Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Bioconcentration: An estimated BCF value of 190 was calculated for dibenzyl ether(SRC), using an experimental log Kow of 3.31(1) and a recommended regression-derived equation(2). An 8-week bioconcentration study using carp and dibenzyl ether concentrations of 0.2 mg/l and 0.02 mg/l gave bioconcentration factors of 171-429 and 187-345, respectively(4). According to a classification scheme(3), these experimental BCF values suggest that bioconcentration in aquatic organisms is high(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 1500(SRC), determined from an experimental log Kow(2) and a recommended regression-derived equation(3), indicates that dibenzyl ether will have slight mobility in soil(SRC). Volatilization of dibenzyl ether is not expected to occur from moist soils, based on an estimated Henry's Law constant of 8.3X10-8 atm-cu m/mol(4) or from dry soils based on an experimental vapor pressure of 1.03X10-3 mm Hg(5). According to a MITI biodegradation test, biodegradation of dibenzyl ether is not expected to be an important fate process in soil(6). However, another study with seawater and river water indicated biodegradation may be rapid(7). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: An estimated Koc value of 1500(SRC), determined from an experimental log Kow(1) and a recommended regression-derived equation(2), indicates that dibenzyl ether would adsorb to suspended solids and sediment(2,SRC) in the water. Dibenzyl ether will be essentially non-volatile from water surfaces based on an estimated Henry's Law constant of 8.3X10-8 atm-cu m/mole(SRC), developed using a fragment constant estimation method(3). Experimental BCF values of 171-429 and 187-345(5) suggest that bioconcentrate of dibenzyl ether will be high aquatic organisms(SRC) according to a classification scheme(4). According to a MITI biodegradation test, biodegradation of dibenzyl ether is not expected to be an important fate process in water(5). However, another study with seawater and river water indicated biodegradation may be rapid(6). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), dibenzyl ether, which has an experimental vapor pressure of 1.03X10-3 mm Hg at 25 °C(2) will exist as a vapor in the ambient atmosphere. Vapor-phase dibenzyl ether 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 about 18 hours(3,SRC).
