Section 3 - Hazards Identification

Appearance: colorless clear liquid. Flash Point: -40 deg C.
Danger! Causes eye and skin burns. Causes digestive and respiratory tract burns. Extremely flammable liquid and vapor. Vapor may cause flash fire. Reacts violently with water. Pyrophoric. Spontaneously flammable in air. Harmful if inhaled.
Target Organs: Nervous system.


Potential Health Effects
Eye: Causes eye burns.
Skin: Causes skin burns.

Section 4 - First Aid Measures

Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids.
Skin: Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes.

Notes to Physician: Treat symptomatically and supportively.

Section 5 - Fire Fighting Measures

General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Extremely flammable liquid and vapor. May re-ignite after fire is extinguished. Containers may explode when heated or if contaminated with water.
Extinguishing Media: Do NOT get water inside containers. Most foams will react with the material and release corrosive/toxic gases. Cool containers with flooding quantities of water until well after fire is out. DO NOT USE WATER OR FOAM. For small fires, use dry chemical, soda ash, lime or sand.

Section 6 - Accidental Release Measures

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Clean up spills immediately, observing precautions in the Protective Equipment section. Use a spark-proof tool. Do not get water on spilled substances or inside containers.

Section 7 - Handling and Storage

Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Avoid ingestion and inhalation. Do not allow contact with water. Avoid mechanical shock and friction. Discard contaminated shoes. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
Storage: Keep away from sources of ignition. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from water. Flammables-area. Keep containers tightly closed.

Section 8 - Exposure Controls, Personal Protection

Engineering Controls: Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits. Use process enclosure, local exhaust ventilation, or other engineering controls to control airborne levels.

Section 12 - Ecological Information

Ecotoxicity: No data available. Cas# 110-54-3:LC50(96Hr.) Rainbow Trout = 4.14 mg/L; Flow-through BioassayLC50(96Hr.)Fathead Minnow=5.10 mg/LLC50(96Hr.)Bluegill = 4.12 mg/LLC50 (48Hr.) Water Flea = 3.87 mg/L
Environmental: Photolysis or hydrolysis of n-hexane are not expected to be important in soils. The biodegradation of n-hexane may occur in soils; however, volatilization and adsorption are expected to be far more important fate processes. A calculated Koc range for n-hexane of 1250 to 4100 indicates a low to slight soil mobility class. Based upon an estimated Henry's Law constant of 1.81 atm-cu m/mole, n-hexane is expected to rapidly volatilize from moist surface soils.
Physical: Photolysis or hydrolysis of n-hexane in aquatic systems are not expected to be important. The log biodegradation of n-hexane may occur in aquatic environments; however, volatilization and adsorption are expected to be far more important fate processes.
Other: No information available.

Section 13 - Disposal Considerations
