Section III. Hazards Identification
    Acute Health Effects        Corrosive to skin, eyes, and respiratory system. Liquid or spray mist may produce tissue damage, particularly in mucous    
    membranes of the eyes, mouth and respiratory tract. Skin contact may produce burns. Eye contact can result in corneal
    damage or blindness. Inhalation of the spray mist may produce severe irritation of respiratory tract, characterized by
    coughing, choking, or shortness of breath. Corrosive materials may cause serious injury if ingested.
    Follow safe industrial hygiene practices and always wear proper protective equipment when handling this compound.
    CARCINOGENIC EFFECTS : Not available.
    Chronic Health Effects
    MUTAGENIC EFFECTS : Not available.
    TERATOGENIC EFFECTS : Not available.
    Toxicity to the reproductive system: Not available. Repeated exposure to an highly toxic material may produce general
    deterioration of health by an accumulation in one or many human organs.

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        If 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.
    Inhalation        If 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.
    Ingestion        DO NOT INDUCE VOMITING. 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.

Section VI.        Accidental Release Measures    
    Spill Cleanup        Corrosive liquid. Combustible material. Lachrymatory material. Moisture sensitive material.    
    Instructions        Keep away from heat. 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. Consult federal, state,
    and/or local authorities for assistance on disposal.

Section VII. Handling and Storage
    CORROSIVE. COMBUSTIBLE. LACHRYMATOR. MOISTURE SENSITIVE. Keep container dry. Keep away from heat.
    Handling and Storage
    Mechanical exhaust required. Avoid excessive heat and light. DO NOT ingest. Do not breathe gas/fumes/ vapor/spray.
    Information
    Never add water to this product. Wear suitable protective clothing. 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.

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.
    Personal Protection        Face shield. 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.
