Section 4: First Aid Measures
Eye Contact: Check for and remove any contact lenses. Do not use an eye ointment. Seek medical attention.
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.
Serious Skin Contact:
Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek immediate medical
Inhalation: Allow the victim to rest in a well ventilated area. Seek immediate medical attention.
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
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.

Section 6: Accidental Release Measures
Small Spill: Absorb with an inert material and put the spilled material in an appropriate waste disposal.
Toxic flammable liquid, insoluble or very slightly soluble in water. Keep away from heat. Keep away from sources of ignition.
Stop leak if without risk. Absorb with DRY earth, sand or other non-combustible material. Do not get water inside container.
Do not touch spilled material. Prevent entry into sewers, basements or confined areas; dike if needed. Eliminate all ignition
sources. Call for assistance on disposal.
Section 7: Handling and Storage
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. 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. Avoid contact with skin and eyes
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).
Section 8: Exposure Controls/Personal Protection
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.
