PRECAUTIONARY INFORMATION
DANGER: Combustible liquid can be fatal by inhalation, ingestion and by skin absorption. Highly toxic by
skin absorption. Severe eye and skin burns. Known liver toxin.
POTENTIAL HEALTH EFFECTS
Primary Routes of Entry
Inhalation, ingestion, skin absorption, and eye contact.
HAZARD CLASSIFICATION
Acute Effects
Cumene Heavies may act as a central nervous system depressant and a narcotic. Inhalation of high vapor concentrations
may cause dizziness, slight incoordination and unconsciousness. This chemical may also be toxic to the liver, spleen and
gall bladder, but there is little human evidence of these effects. This chemical is also a skin and eye irritant.
Chronic Effects
Cumene Heavies may cause skin rashes due to prolonged contact. Chronic experiments in animals found
isopropylbenzene to cause damage to the spleen and fatty changes in the liver, but no renal or pulmonary irritancy.
Subacute inhalation experiments showed no significant changes in peripheral blood, but exhibited some liver, kidney and
lung effects.
Potential Adverse Chemical Interactions
Persons with liver or kidney diseases should not be exposed to cumene heavies for any length of time, even
intermittently, since this chemical can damage these organs. Blood forming organs may be impaired by exposure to
cumene heavies.

Unusual Fire and Explosion Hazards
Cumene heavies is a fire and explosion hazard when heated. The heavier-than-air vapors can flow along surfaces to a
distant ignition source and flash back. Vapors can flow along surfaces to distant ignition sources and then flash back.
Fire Fighting Procedures/Fire Extinguishing Media
Keep unnecessary people away; isolate hazard area and deny entry. Avoid breathing vapors, stay upwind, out of low
areas and ventilate closed spaces before entering. Use NIOSH approved self-contained respirators in the positive
pressure mode, and chemical protective clothing. No skin areas should be exposed. Do not enter fire area without full
bunker gear (helmet with face shield, bunker coats, gloves, and rubber boots). Use halon replacement or carbon dioxide
extinguishers. Water spray may be insufficient in putting out a fire, but use it to cool fire-exposed containers to prevent
rupture. Use of a water stream on burning liquid can scatter flames. If a leak or spill has not ignited, use water spray to
disperse vapors. Fight fire from maximum distance.

6. ACCIDENTAL RELEASE MEASURES
Shut off all sources of ignition. Restrict access to spill area. Allow only trained personnel with appropriate respirator
and full body protective clothing in the spill area. Highly toxic, do not touch spilled material; stop leak if you can do so
without risk. Prevent cumene heavies from entering water bodies, drains, or any sewage collection systems. For small
spills take up with sand or other non-combustible absorbent material and place into containers for later disposal. Control
large spills by diking and pump to salvage vessels. Do not allow liquid to enter a confined space, such as a sewer,
because of the possibility of an explosion. Dispose all spill material in accordance with federal, state, and local
regulations. Isopropylbenzene spills over the CERCLA reportable quantity (5,000 lbs) should be reported to the National
Response Center (800-424-8802) and/or appropriate state and local agencies.

12. ECOLOGICAL INFORMATION
Environmental Fate: The following information on cumene heavies is extracted from the TOXNET database
maintained by the National Library of Medicine.
Cumene:
Atmosphere: According to a model of gas/particle partitioning of semi-volatile organic compounds in the
atmosphere, cumene, which has a vapor pressure of 4.5 mm Hg at 25 deg C, is expected to exist solely as a vapor
in the ambient atmosphere. Vapor-phase cumene is degraded in the atmosphere by reaction with photochemically-
produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 2.5 days, calculated from its rate
constant of 6.5x10-12 cu cm/molecule-sec at 25 deg C. Vapor-phase cumene is also degraded in the atmosphere by
reaction with ozone radicals; the half-life for this reaction in air is estimated to be 3 yrs, calculated from its
estimated rate constant of 1.0x10-20 cu cm/molecule-sec at 25 deg C.

12. ECOLOGICAL INFORMATION (continued)
Terrestrial: Based on a classification scheme, an estimated Koc value of 820, determined from a structure estimation
method, indicates that cumene is expected to have low mobility in soil. Volatilization of cumene from moist soil surfaces
is expected to be an important fate process given a Henry's Law constant of 0.0115 atm-cu m/mole. The potential for
volatilization of cumene from dry soil surfaces may exist based upon a vapor pressure of 4.5 mm Hg. However,
adsorption to soil is expected to attenuate volatilization. After a 10 and 20 day exposure of wastewater inoculum to
cumene, a theoretical BOD of 62% and 70% was observed, respectively. Based on these results, cumene is expected to
undergo considerable biodegradation in soil environments.
Aquatic: Based on a classification scheme, an estimated Koc value of 820, determined from an estimation method,
indicates that cumene is expected to adsorb to sediment and suspended solids in water. Volatilization from water surfaces
is expected based upon a Henry's Law constant of 0.0115 atm-cu m/mole. Using this Henry's Law constant and an
estimation method, volatilization half-lives for a model river and model lake are 1.2 hrs and 4.4 days, respectively. In
natural waters, cumene is degraded by reaction with hydroxyl radicals; the half-life for this reaction in water is estimated
to be 107 days, calculated from its rate constant of 7.5x109 L/mol sec at pH 7.
Biodegradation:
Aerobic: Using river water and sediment in a test system, the aerobic biodegradation of cumene was studied in a closed
system. The disappearance rate constant of cumene (avg concn 2.5 mg/l) for total mineralization was 0.02/day; this
equates to a half-life of 34.6 days. However, when volatilization was considered coupled with biodegradation, the half-
life for cumene became 2.5 days. Cumene biodegradation experienced a lag time of approximately 5 days. Based on the
results of this experiment, residence time of cumene in aquatic ecosystems will likely be brief.
Anaerobic: In an in-situ anaerobic biodegradation study of various alkyl benzene compounds, cumene was found to
undergo considerable biodegradation. Biodegradation proceeded via methanogenic and fermentative bacteria.
Ecotoxicity:
LC50 Daphnia magna 0.6 ppm/48 hr /Conditions of bioassay not specified
LD50 Agelaius phoeniceus (red-winged blackbird) oral 98 mg/kg
Mytilus edulis (mussel larvae): no significant alteration of growth rate at concentrations of 1 to 50 ppm.
Diisopropenylbenzene:
Atmosphere: Based upon vapor pressures of 0.25 to 0.39 mm Hg at 25 deg C, the diisopropylbenzene isomers are
expected to exist almost entirely in the vapor-phase in the ambient atmosphere. Diisopropylbenzene will degrade in an
average ambient atmosphere by reaction with photochemically produced hydroxyl radicals (estimated half-life of 30
hours)
Terrestrial: Based upon an estimated Koc value of 4000, diisopropylbenzene is expected to be relatively immobile in
soil. Insufficient data are available to predict the rates or importance of soil degradation processes.
Aquatic: Volatilization and adsorption to sediment may be important transport processes in water for diisopropylbenzene.
Volatilization half-lives of 3.8 and 45 hours can be estimated for a model river (1 meter deep) and model pond (2 meters
deep), respectively, when the effects of adsorption are not present; in the presence of adsorption (Koc of 4000), the
volatilization half-life from the pond increases to 27 days. Based upon an estimated Koc of 4000, diisopropylbenzene may
partition from the water column to sediment and suspended material. Insufficient data are available to predict the
importance of biodegradation.
Biodegradation: The rate constant for the vapor-phase reaction of diisopropylbenzene with photochemically produced
hydroxyl radicals has been estimated to be about 1.3X10-11 cu cm/molecule-sec at 25 deg C which corresponds to an
atmospheric half-life of about 30 hrs at an atmospheric concn of 5X10+5 hydroxyl radicals per cu cm. Benzenes are
generally resistant to aqueous environmental hydrolysis, therefore, diisopropylbenzene is not expected to hydrolyze in the
environment
