Section 4. First Aid Measures
Eye ContactCheck for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water
for at least 15 minutes. Cold water may be used. Get medical attention immediately.
Skin ContactIn case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing
contaminated clothing and shoes. Cover the irritated skin with an emollient. Cold water may be used.Wash
clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention immediately.
Serious Skin ContactWash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek medical
attention.
InhalationIf inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Get medical attention immediately.
Serious InhalationEvacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or
waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth
resuscitation. WARNING: It may be hazardous to the person providing aid to give mouth-to-mouth
resuscitation when the inhaled material is toxic, infectious or corrosive. Seek immediate medical attention.
IngestionDo NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to
an unconscious person. If large quantities of this material are swallowed, call a physician immediately.
Loosen tight clothing such as a collar, tie, belt or waistband.
