    Check for and remove any contact lenses. DO NOT use an eye ointment. Flush eyes with running water for a minimum of 15
    Eye Contact
    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
