Section 4. First Aid Measures
Eye Contact Check for and remove any contact lenses. Do not use an eye ointment. Seek medical attention.
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 Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek immediate
medical attention.
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 Do 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.
Serious Ingestion Not available.

ingest. Do not breathe gas/fumes/ vapour/spray. In case of insufficient ventilation, wear suitable respiratory
equipment If ingested, seek medical advice immediately and show the container or the label. Avoid contact with
skin and eyes Keep away from incompatibles such as moisture.
Flammable materials should be stored in a separate safety storage cabinet or room. Keep away from heat. Keep
Storage
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掳C (100掳F).
Section 8. Exposure Controls/Personal Protection
Engineering Controls Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors below their
respective threshold limit value. Ensure that eyewash stations and safety showers are proximal to the
work-station location.
Personal Protection Splash goggles. Lab coat. Vapor respirator. Be sure to use an approved/certified respirator or equivalent.
Gloves.
Personal Protection in Case of Splash goggles. Full suit. Vapor respirator. Boots. Gloves. A self contained breathing apparatus should be
a Large Spill used to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist
BEFORE handling this product.
