Section IV.First Aid Measures
Eye ContactCheck for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15
minutes. Get medical attention.
Skin ContactIn case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention immediately.
InhalationIf the victim is not breathing, perform mouth-to-mouth resuscitation. Loosen tight clothing such as a collar, tie, belt or
waistband. If breathing is difficult, oxygen can be administered. Seek medical attention if respiration problems do not
improve.
IngestionINDUCE VOMITING by sticking finger in throat. Lower the head so that the vomit will not reenter the mouth and throat.
Loosen tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing, perform mouth-to-mouth
resuscitation. Examine the lips and mouth to ascertain whether the tissues are damaged, a possible indication that the toxic
material was ingested; the absence of such signs, however, is not conclusive.

Ecotoxicity
Environmental FateToluene is released into the atmosphere principally from the volatilization of petroleum fuels and toluene-based solvents and
thinners and from motor vehicle exhaust. Toluene’s production and use as an intermediate in the production of benzoic acid,
benzaldehyde, benzene, explosives, dyes and many other organic compounds may also result in its release to the
environment through various waste streams. Toluene has been detected in emissions from volcanos, forest fires and crude
oil. If released to air, a vapor pressure of 28.4 mm Hg at 25 deg C indicates toluene will exist solely as a vapor in the ambient
atmosphere. Vapor-phase toluene 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 3 days. Toluene may also be degraded in the atmosphere by
reaction with nitrate radicals and ozone molecules, but these reactions are too slow to be environmentally important. If
released to soil, toluene is expected to have high to moderate mobility based upon Koc values in the range of 37-178.
Volatilization from moist soil surfaces is expected to be an important fate process based upon a Henry’s Law constant of
6.64X10-3 atm-cu m/mole. Toluene may volatilize from dry soil surfaces based upon its vapor pressure. Biodegradation is
expected to occur rapidly in soil surfaces, with half-lives in the range of several hours to 71 days. If released into water,
toluene is not expected to adsorb to suspended solids and sediment based upon a Koc of 166 measured in lake sediment.
Biodegradation is expected to occur rapidly in water, with reported half-lives of and 56 days in aerobic and anaerobic water,
respectively. Volatilization from water surfaces is expected to be an important fate process based upon this compound’s
Henry’s Law constant. Estimated volatilization half-lives for a model river and model lake are 1 hour and 4 days, respectively.
Measured BCF values of 13 and 90 in fish suggest bioconcentration in aquatic organisms is low to moderate. Hydrolysis is
not expected to be an important environmental fate process for toluene due to lack of hydrolyzable functional groups.
Exposure to toluene may occur occupationally during its production or subsequent use, particularly as a solvent or in gasoline,
via dermal and respiratory routes. The main route of exposure for the general population will be through inhalation from
contaminated air and handling of gasoline as well as ingestion of contaminated drinking water and food, and exposure to
some consumer products.

Section XIII. Disposal Considerations
Recycle to process, if possible. Consult your local regional authorities. You may be able to dissolve or mix material with a
