Section 4: First Aid Measures

Eye Contact: No known effect on eye contact, rinse with water for a few minutes.

Skin 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. Cover the irritated skin with an
emollient. If irritation persists, seek medical attention. Wash contaminated clothing before reusing.
Serious Skin Contact:

Inhalation: Allow the victim to rest in a well ventilated area. Seek immediate medical attention.
Serious 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
attention.
Ingestion:

Section 7: Handling and Storage

Precautions:

Keep away from heat. Keep away from sources of ignition. Ground all equipment containing material. Do not ingest. Do not
breathe gas/fumes/ vapour/spray. Avoid contact with skin Wear suitable protective clothing In case of insufficient ventilation,
wear suitable respiratory equipment If ingested, seek medical advice immediately and show the container or the label.
Storage:
Flammable materials should be stored in a separate safety storage cabinet or room. Keep away from heat. Keep away from
sources of ignition. Keep container tightly closed. Keep in a cool, well-ventilated place. Ground all equipment containing
material. A refrigerated room would be preferable for materials with a flash point lower than 37.8°C (100°F).
