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. Get medical attention if irritation occurs.
Skin ContactWash with soap and water. Cover the irritated skin with an emollient. Get medical attention if irritation
develops.
Serious Skin ContactNot available.
InhalationIf inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Get medical attention.
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. Seek medical attention.
IngestionIf swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. Loosen tight clothing such as a collar, tie, belt or waistband. Get medical
attention immediately.
