Special Fire Fighting Procedures - Unusual Hazards.
Wear full protective equipment, including respiratory protection. Avoid using water, as material reacts strongly with
water.
Section V - Health Hazard Data
Toxicity (LD50, LC50, etc.): Toxicological properties have not been thoroughly investigated.
Effects of Overexposure: Although toxicological effects have not been thoroughly investigated, some degree of
toxicity is suspected. Harmful by inhalation, ingestion, or contact with skin. Vapors are irritating to eyes, mucous
membranes, and upper respiratory tract. Causes skin irritation. Contact with liquid may damage eyes. Assumed to
be dangerous if ingested. Always use precautions to minimize exposure to this product, including ventilation hoods
or personal protective equipment if necessary.
Emergency and First Aid Procedures:
EYES: Flush immediately with large quantities of water for at least 15 minutes. Insure good flush by holding eye
lids open if necessary. Get medical attention in all cases.
SKIN: Wash affected area with large amounts of water followed by a soap and water wash. Remove any
contaminated clothing. If adverse conditions appear, seek medical attention.
INGESTION: Rinse mouth with water, insuring that rinse is not swallowed. Give about 1/2 pint of milk or water
to dilute stomach contents and seek immediate medical attention.
INHALATION: Remove to fresh air. Rest and keep at a comfortable temperature. Give oxygen if breathing seems
difficult, or mouth-to-mouth resuscitation if necessary. Get medical attention if there seems to be continuing ill
effects.
Section VI - Reactivity Data
General Reactivity: Reacts with water in a violent manner.
Incompatibility (Materials to Avoid): Water and caustic materials.
Hazardous Decomposition Products: Toxic fumes of carbon dioxide, carbon monoxide, nitrogen oxides, and
hydrogen fluoride.
Hazardous Polymerization: Conditions to Avoid: Moisture, excessive heat.
Will not occur.
Section VII - Spill Procedures, Disposal Requirements
For medium to large spills, wear full personal protective equipment including chemical resistant boots, gloves, and
suit, combined with respiratory protection up to supplied air. Smaller spills may be handled with air-purifying
respirator with organic cartridges, chemical resistant gloves, and eye protection. Use absorbent or oil dry to clean up
liquids, and place contaminated absorbent in a proper container for disposal by EPA approved methods, including
RCRA incineration. Pure material may be sent for RCRA incineration or fuel blending, if appropriate.
Section VIII - Personal Protective Equipment
Use air-purifying resrirator with organic cartridges (full faced, or half faced with goggles for eye protection), or
supplied air for more concentrated vapors. Use chemical resistant gloves, and clothing if necessary. Always use
mechanical ventilation if possible.
Section IX - Special Requirements
Keep tightly closed. Moisture sensitive. Store in a cool dry place.
