Section III. Hazards Identification
    Harmful if ingested or inhaled. Minimize exposure to this material. Severe overexposure can result in injury or death.
    Acute Health Effects
    Irritating to eyes and skin on contact. Inhalation causes irritation of the lungs and respiratory system. Inflammation of the
    eye is characterized by redness, watering, and itching. Skin inflammation is characterized by itching, scaling, reddening, or,
    occasionally, blistering.
    Skin contact may result in sensitization. Always cover all exposed skin with an impermeable layer and use proper eye
    protection. A OSHA/MSHA approved dust and vapor respirator is required when working with this material.
    Follow safe industrial hygiene practices and always wear proper protective equipment when handling this compound.

Section IV.        First Aid Measures    
    Eye Contact        Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15    
    minutes. Get medical attention.
    Skin Contact        In case of contact, immediately flush skin with plenty of water. Remove contaminated clothing and shoes. Wash clothing    
    before reuse. Thoroughly clean shoes before reuse. Get medical attention.
    If the victim is not breathing, perform mouth-to-mouth resuscitation. Loosen tight clothing such as a collar, tie, belt or
    Inhalation
    waistband. If breathing is difficult, oxygen can be administered. Seek medical attention if respiration problems do not
    improve.
    INDUCE VOMITING by sticking finger in throat. Lower the head so that the vomit will not reenter the mouth and throat.
    Ingestion
    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.
