FIRST AID MEASURES Eye Contact Check for and remove contact lenses. Immediately flush eyes with plenty of water, holding eyelids open for at least 15 minutes. Consult a physician. Skin Contact Remove contaminated clothing. Immediately flush skin with plenty of water for at least 15 minutes. Call a physician. Inhalation Remove the person from exposure. Bring to fresh air. If breathing is difficult, give oxygen. In this case get immediate medical attention. Ingestion DO NOT induce vomiting. Conscious and alert person : Rinse mouth with water and give ½ to 1 cup of water or milk to dilute material. Spontaneous vomiting : Have the individual lean forward with head down to avoid breathing in vomit ; Rinse mouth and give ½ to 1 cup of water or milk.
