SECTION 4. FIRST AID MEASURES

General Treatment:
Seek medical attention if symptoms persist.
Special Treatment:
None
Important Symptoms:
Causes severe skin burns
Causes severe eye damage
Inhalation:
Remove victim to fresh air. Supply oxygen if breathing is difficult.
Ingestion:
Give one to two glasses of water and induce vomiting. Never induce vomiting or give anything by mouth to an unconscious person.
Skin:
Immediately remove any clothing soiled by the product. Wash affected area with mild soap and water. Remove any contaminated clothing.
Eyes:
Flush eyes with water, blinking often for several minutes. Remove contact lenses if present and easy to do. Continue rinsing.


SECTION 5. FIREFIGHTING MEASURES

Flammbable
Extinguishing Media:
Do not use water for metal fires – use CO2, sand, extinguishing powder.
Spec. Fire Fighting Procedure:
Use full-face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes. See section 10 for decomposition products.


SECTION 6. ACCIDENTAL RELEASE MEASURES

If Material Is Released/Spilled:
Wear appropriate respiratory and protective equipment specified in special protection information. Isolate spill area and provide ventilation. Vacuum up spill using a high efficiency particulate
absolute (HEPA) air filter and place in a closed container for disposal. Take care not to raise dust.
Environmental Precautions:
Isolate runoff to prevent environmental pollution.
