Section IV.First Aid Measures
Eye ContactCheck for and remove any contact lenses. DO NOT use an eye ointment. Flush eyes with running water for a minimum
of 15 minutes, occasionally lifting the upper and lower eyelids. Seek medical attention. Treat symptomatically and
supportively.
Skin ContactIf the chemical gets spilled on a clothed portion of the body, remove the contaminated clothes as quickly as possible,
protecting your own hands and body. Place the victim under a deluge shower. If the chemical touches the victim's
exposed skin, such as the hands: Gently and thoroughly wash the contaminated skin with running water and non-abrasive
soap. Be particularly careful to clean folds, crevices, creases and groin. Cover the irritated skin with an emollient. Seek
medical attention. Treat symptomatically and supportively. Wash any contaminated clothing before reusing.
InhalationIf the victim is not breathing, perform artificial respiration. Loosen tight clothing such as a collar, tie, belt or waistband. If
breathing is difficult, oxygen can be administered. Seek medical attention. Treat symptomatically and supportively.
Remove dentures if any. Have conscious person drink several glasses of water or milk. INDUCE VOMITING by sticking
Ingestion
finger in throat. Lower the head so that the vomit will not reenter the mouth and throat. NEVER give an unconscious
person anything to ingest. Seek medical attention. Treat symptomatically and supportively.

Section VI.Accidental Release Measures
Spill CleanupCombustible material.
InstructionsKeep away from heat and sources of ignition. Mechanical exhaust required. Stop leak if without risk. Finish cleaning the
spill by rinsing any contaminated surfaces with copious amounts of water.

---

Section VII. Handling and Storage
Keep away from heat and sources of ignition. Mechanical exhaust required. When not in use, tightly seal the container
Handling and Storage
and store in a dry, cool place. Avoid excessive heat and light. Do not breathe gas, fumes, vapor or spray. In case of
Information
insufficient ventilation, wear suitable respiratory equipment. If you feel unwell, seek medical attention and show the label
when possible. Treat symptomatically and supportively. Avoid contact with skin and eyes.
Always store away from incompatible compounds such as oxidizing agents.

---

Section VIII. Exposure Controls/Personal Protection
Engineering ControlsProvide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors below their
respective threshold limit value. Ensure that eyewash station and safety shower is proximal to the work-station location.
Personal ProtectionSplash goggles. Lab coat. Vapor respirator. Boots. Gloves. A MSHA/NIOSH approved respirator must be used to avoid
inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling
this product.

2-Isopropylnaphthalene (beta-)

Section XII.Ecological Information
EcotoxicityNot available.
2-Isopropylnaphthalene is a component of crude oil and a product of combustion which is produced and released to the
Environmental Fate
environment during natural fires. Emissions from petroleum refining, coal tar distillation, and gasoline and diesel fueled
engines are contributors of 2-isopropylnaphthalene to the environment. 2-Isopropylnaphthalene is also used as chemical
intermediate and a general solvent. Consequently, 2-isopropylnaphthalene is released to the environment via
manufacturing effluents. 2-Isopropylnaphthalene is also released to the environment by municipal waste incinerators.
2-Isopropylnaphthalene should biodegrade in the environment. However, hydrolysis of 2-isopropylnaphthalene should not
be important. In sunlit environmental media, 2-isopropylnaphthalene will undergo direct photolysis. 2-Isopropylnaphthalene
is expected to be slightly mobile to immobile in soil. 2-Isopropylnaphthalene has the potential to bioconcentrate in aquatic
organisms. 2-Isopropylnaphthalene may also partition from the water column to organic matter contained in sediments
and suspended solids. Volatilization of 2-isopropylnaphthalene from environmental waters may be important. The
volatilization half-lives from a model river and a model pond, the latter considers the effect of adsorption, have been
estimated to be 5.2 hr and 93.6 days, respectively. 2-Isopropylnaphthalene is expected to exist entirely in the vapor phase
in ambient air. In the atmosphere, reaction with photochemically produced hydroxyl radicals (half-life of 6.6 hr) is likely to
be important. The most probable human exposure would be occupational exposure, which may occur through dermal
contact or inhalation at places were 2-isopropylnaphthalene is produced or used. Non-occupational exposures would most
likely occur via urban atmospheres, contaminated drinking water supplies and recreational activities at contaminated
waterways. (Excerpted from HSDB, 1996)

Section XIII. Disposal Considerations
Waste DisposalRecycle to process, if possible. Consult your local or regional authorities. You may be able to dissolve or mix material with
a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber system. Observe all
federal, state, and local regulations when disposing of this substance.
