SECTION 4. FIRST AID MEASURES

General Treatment: Seek medical attention if symptoms persist.
Special Treatment: None
Important Symptoms: None
Inhalation: Remove victim to fresh air. Supply oxygen if breathing is difficult.
Ingestion: Do not induce vomiting. Seek immediate medical attention.
Skin: Remove any contaminated clothing. Wash affected area with mild soap
and water.
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

Flammability: Non-flammable, except as powder
Extinguishing Media: Do not use water for metal fires – use 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


SECTION 7. HANDLING AND STORAGE

Handling Conditions: Wash thoroughly after handling.
Storage Conditions: Store in a cool dry place in a tightly sealed container. Store apart from
materials and conditions listed in section 10.

eating and smoking. Do not blow dust off clothing or skin with
compressed air.
Ventilation: Provide sufficient ventilation to maintain concentration at or below
threshold limit.


SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION
