SECTION 3: Hazards Identification
Emergency Overview:	Extremely flammable liquid. Will ignite spontaneously on contact with air. Contact with skin may result in severe chemical burns.
Primary Routes of Exposure:	Eyes, skin and inhalation
Eye Contact:	Material is a severe corrosive of the eyes.
Skin Contact:	Contact with the skin will result in severe chemical burns as the material may spontaneously ignite.
Inhalation:	Combustion products may be irritating to respiratory tract.
Ingestion:	Ingestion is an unlikely mode of entry as the material is pyrophoric and has a noxious odor.
Acute Health Effects:	Corrosive to skin, eyes, and respiratory tract.
Chronic Health Effects:	No information available on long term exposure to this material.
NTP:	No
IARC:	No
OSHA:	No

SECTION 4: First Aid Measures
Eye Exposure:	Immediately flush the eyes with copious amounts of water for at least 15 minutes. A victim will need assistance in keeping their eye lids open. Get immediate medical attention.
Skin Exposure:	Wash the affected area immediately with water. Remove contaminated clothing if necessary. Seek medical assistance if irritation persists.
Inhalation:	Remove victim to fresh air immediately. Keep the victim lying down and warm. Give oxygen as soon as possible. If shock occurs, respond with appropriate first aid. Transport the victim to a hospital.
Ingestion:	Seek medical attention immediately. Keep the victim calm. Give water to dilute the toxin (only if conscious). Induce vomiting only if directed by medical personnel.

SECTION 5: Fire Fighting Measures
Flash Point:	pyrophoric
Autoignition Temperature:	pyrophoric
Explosion Limits:	no data available
Extinguishing Medium:	dry chemical or foam
Special Fire Fighting Procedures:	Material will spontaneously ignite when exposed to air. Fire fighters must be equipped with a NIOSH-approved positive pressure self-contained breathing apparatus.
Hazardous Combustion and Decomposion Products:	carbon monoxide, carbon dioxide, aluminum oxide, and organic fumes.
Unusual Fire or Explosion Hazards:	Pyrophoric material. Will spontaneously ignite if exposed to air.

SECTION 6: Accidental Release Measures
Spill and Leak Procedures:	If spilled, the product will ignite. All personnel must be immediately evacuated and the area sealed off. The material may ignite releasing toxic and corrosive fumes. Ventilation should be available. If entry into the area is required, personnel should be fitted with a self-contained breathing apparatus.

SECTION 7: Handling and Storage
Handling and Storage:	Material must be stored in a steel container under and inert atmosphere of nitrogen or argon. Store at room temperature. Keep away from heat.

SECTION 8: Exposure Controls and Personal Protection
