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 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention.
Skin Exposure:	Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if irritation persists.
Inhalation:	Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance.
Ingestion:	Seek medical attention immediately. Keep the victim calm. Give the victim water (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
Extinguishing Medium:	dry chemical or foam
Special Fire Fighting Procedures:	If this product is involved in a fire, fire fighters should be equipped with a NIOSH approved positive pressure self-contained breathing apparatus and full protective clothing.
