4: First Aid Measures Eye Contact:
for and remove any contact lenses. Immediately flush eyes with running water for
at least 15 minutes, keeping eyelids open. Cold water may be used. Do not use an
eye ointment. Seek medical attention.
Contact: After contact
with skin, wash immediately with plenty of water. Gently and thoroughly wash the
contaminated skin with running water and non-abrasive soap. Be particularly
careful to clean folds, crevices, creases and groin. Cold water may be used.
Cover the irritated skin with an emollient. If irritation persists, seek medical
attention. Wash contaminated clothing before reusing.
Skin Contact: Wash with a
disinfectant soap and cover the contaminated skin with an anti-bacterial cream.
Seek immediate medical attention.
Allow the victim to rest
in a well ventilated area. Seek immediate medical attention.
Inhalation: Evacuate 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
not induce vomiting. 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. Loosen tight clothing such as
a collar, tie, belt or waistband. If the victim is not breathing, perform
mouth-to-mouth resuscitation. Seek immediate medical attention.
