Hazardous Skin Wash with a disinfectant soap and cover the contaminated Contact skin with an anti—bacterial cream. Seek medical

attention.

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

Hazardous Evacuate the victim to a safe area as soon as possible. Inhalation 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.

**Section VI. Accidental Release Measures**

Small Spill Dilute with water and mop up, or absorb with an inert DRY material and place in an appropriate waste disposal container.

Large Spill Flammable liquid.

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 touch spilled material. Prevent entry into sewers, basements or confined areas; dike if needed. Eliminate all sources of ignition. Be careful that the product is not present at a concentration level above TLV. Check TLV on the MSDS and with local authorities.

**Section VII. 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, vapor or 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 oxidizing agents.

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
