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 ContactAfter contact with skin, wash immediately with plenty of water. 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.
Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or waistband. If
Inhalation
breathing is difficult, administer oxygen. If the victim is not breathing, perform artificial respiration. WARNING: It may be
dangerous to the person providing aid to give mouth-to-mouth resuscitation when the inhaled material is toxic, infectious
or corrosive. Seek medical attention. Treat symptomatically and supportively.
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, administer artificial respiration.
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. Seek immediate medical attention and, if possible,
show the chemical label. Treat symptomatically and supportively.

Section VI.Accidental Release Measures
Spill CleanupCombustible material. Irritating material.
InstructionsKeep away from heat and sources of ignition. Mechanical exhaust required. Stop leak if without risk. Absorb with DRY
earth, sand or other non-combustible material. DO NOT get water inside container. DO NOT touch spilled material. Use
water spray curtain to divert vapor drift. Prevent entry into sewers, basements or confined areas; dike if needed.
Eliminate all sources of ignition. Consult federal, state, and/or local authorities for assistance on disposal.

Section VII. Handling and Storage
Handling and StorageCOMBUSTIBLE. IRRITANT. Keep away from heat and sources of ignition. Mechanical exhaust required. When not in
use, tightly seal the container and store in a dry, cool place. Avoid excessive heat and light. DO NOT ingest. Do not
Information
breathe gas, fumes, vapor or spray. In case of insufficient ventilation, wear suitable respiratory equipment. If ingested,
seek medical advice immediately and show the container or the label. Treat symptomatically and supportively. Avoid
contact with skin and eyes.
Always store away from incompatible compounds such as oxidizing agents, alkalis (bases).

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.
