SECTION 3: Hazards Identification
Emergency Overview:	Extremely flammable liquid. Vapors corrosive to eyes and respiratory tract and may depress central nervous system causing dizziness, headache and nausea. Liquid may cause thermal burns to skin and eyes.
Primary Routes of Exposure:	Eyes, skin, and inhalation of combustion products.
Eye Contact:	Direct contact of liquid with the eyes will cause thermal burns and possible blindness.
Skin Contact:	Residue upon evaporation of hexane may burst into flame causing thermal burns.
Inhalation:	Inhalation of vapors may depress the central nervous system causing dizziness, difficulty in walking, and burns to the lungs.
Ingestion:	Ingestion may cause gastrointestinal burns, nausea, vomiting and headache.
Acute Health Effects:	Causes burns to skin and eyes. Inhalation can lead to dizziness and difficulty in walking. Ingestion may cause gastrointestinal irritation, nausea, vomiting and headache.
Chronic Health Effects:	The chronic toxicological properties of this compound have not been thoroughly investigated. Overexposure may affect the skin, eyes and respiratory system.
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:	-9°F (hexane)
Autoignition Temperature:	no data
Explosion Limits:	no data
Extinguishing Medium:	Vermiculite, sand, dry chemical. Use no water
Special Fire Fighting Procedures:	Fire fighters should be equipped with a NIOSH approved positive pressure self-contained breathing apparatus and full protective clothing. Flood burning skin with a large excess of water.
Hazardous Combustion and Decomposion Products:	Highly flammable. If involved in a fire this material may irritating fumes of alumina dust
Unusual Fire or Explosion Hazards:	Extremely flammable. If hexane is allowed to evaporate, material becomes pyrophoric.

SECTION 6: Accidental Release Measures
Spill and Leak Procedures:	The material may ignite spontaneously in air. Burning material may release toxic fumes. Leave the area unless fitted with a self-contained breathing apparatus. Smother fire with dry powder. Material reacts with water.

SECTION 7: Handling and Storage
Handling and Storage:	Store under dry argon or nitrogen away from other flammable materials. Transfer using metal, not plastic materials. Expect fire when disassembling used piping. Do not use flammable solvents to clean out piping.

SECTION 8: Exposure Controls and Personal Protection
Eye Protection:	Always wear approved safety glasses when handling a chemical substance in the laboratory.
Skin Protection:	Wear protective clothing and loose fitting rubber or leather gloves.
Ventilation:	If possible, handle the material in an efficient fume hood.
Respirator:	If ventilation is not available a respirator should be worn. The use of respirators requires a Respirator Protection Program to be in compliance with 29 CFR 1910.134.
Additional Protection:	Wear a full face shield, and rubber lab apron.
