Section IV.        First Aid Measures    
    Eye Contact        Check 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 Contact        After 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.
    Ingestion        INDUCE 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.

    Information
    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, reducing agents, alkalis (bases).

Section VIII. Exposure Controls/Personal Protection
    Engineering Controls        Provide 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.
    Splash goggles. Lab coat. Vapor respirator. Boots. Gloves. A MSHA/NIOSH approved respirator must be used to avoid

Section XII.        Ecological Information    
    Ecotoxicity        Not available.    
    2-Methylpentaldehyde's production and use as a flavoring ingredient and an intermediate for dyes, resins, and
    Environmental Fate
    pharmaceuticals may result in its release to the environment through various waste streams. 2-Methylpentaldehyde is a
    volatile component in onion, garlic,milk, meat, and roasted peanuts. 2-Methylpentaldehyde has also been found in sea
    water near Denmark. If released to soil, 2-methylpentaldehyde will have very high mobility. Volatilization of
    2-methylpentaldehyde may be important from moist and dry soil surfaces. Insufficient experimetnal data are available to
    determine the rate or importance of biodegradation of 2-methylpentaldehyde in soil or water, but simple aldehydes are
    generally biodegradable. If released to water, 2-methylpentaldehyde may not adsorb to suspended solids and sediment.
    2-Methylpentaldehyde may volatilize from water surfaces with estimated half-lives for a model river and model lake of 5.3
    hours and 4.7 days, respectively. An estimated BCF value of 5.6, suggests that 2-methylpentaldehyde will not
    bioconcentrate in aquatic organisms. If released to the atmosphere, 2-methylpentaldehyde will exist in the vapor phase.
    Vapor-phase 2-methylpentaldehyde is degraded in the atmosphere by reaction with photochemically produced hydroxyl
    radicals with an estimated half-life of about 13 hours. The general population can be exposed to 2-methylpentaldehyde in
    food stuffs based on its natural existence as a volatile component in onion, garlic, milk, meat, and roasted peanuts, its use
    as a flavoring ingredient, and through ingestion, inhalation, and dermal contact. (SRC)

Section XIII. Disposal Considerations
    Waste Disposal        Recycle 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.
