3. Hazards Identification
EMERGENCY OVERVIEW
Vapors irritating to the eyes and respiratory system. Skin contact may cause irritation and dermatitis.
Inhalation of vapors may depress the central nervous system causing dizziness, headache and
nausea and eventual loss of consciousness and respiratory paralysis at very high concentrations.
Flammable.

Yes Yes Yes
Synergistic Effects
None reported
Carcinogenicity: -- NTP: No IARC: No OSHA: No
EYE EFFECTS:
Contact will cause irritation, redness and a burning sensation. Persons with potential exposure to hexane should
not wear contact lenses.
SKIN EFFECTS:
Hexane is an irritant to the skin and can be absorbed through the skin in harmful amounts.
INGESTION EFFECTS:
Ingestion may cause gastrointestinal irritation, nausea, vomiting and headache.
INHALATION EFFECTS:
Inhalation of the vapors may depress the central nervous system causing dizziness, difficulty in walking,
respiratory tract irritation, numbness of the extremeties and may result in eventual respiratory paralysis at very
high concentrations.
Some evidence indicates hexane may cause mutagenic, teratogenic, and/or reproductive effects
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE:
Any type of paresthesia may be aggravated by hexane exposure.
NFPA HAZARD CODES HMIS HAZARD CODES RATINGS SYSTEM
Health: 1 Health: 1 0 = No Hazard
Flammability: 3 Flammability: 3 1 = Slight Hazard
Reactivity: 0 Reactivity: 0 2 = Moderate Hazard

4. First Aid Measures
EYES:
Flush contaminated eye(s) with copious quantities of water. Part eyelids with fingers to assure complete
flushing. Continue for minimum of 15 minutes. Seek medical attention.
SKIN:
Flush affected area with large quantities of water. Remove contaminated clothing as rapidly as possible.
INGESTION:
Do not induce vomiting as aspiration into the lung may cause pulmonary edema and complications. Do not
administer milk, alcohol or fatty foods. Lay victim down in a cool, quiet, well ventilated area and keep warm
with a blanket. Consult a poison control center for instructions as soon as possible.
INHALATION:
MSDS: G-38
Revised: 6/7/96 Page 2 of 7
PRODUCT NAME: HEXANE
Conscious persons should be assisted to an uncontaminated area and inhale fresh air. Quick removal from the
contaminated area is most important. Unconscious persons should be moved to an uncontaminated area and
given artificial resuscitation and supplemental oxygen. Further treatment should be symptomatic and supportive.
PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE TO
HEXANE. Rescue personnel should be equipped with self-contained breathing apparatus and be aware of
extreme fire and explosion hazard.
5. Fire Fighting Measures
Conditions of Flammability: Liquid and vapor flammable
Flash point: Method: Autoignition
-7 oF (-22 oC) Not Available Temperature: Not Available
LEL(%): 1.7 UEL(%): 7.7
Hazardous combustion products: Typical for burning hydrocarbon
Sensitivity to mechanical shock: None
Sensitivity to static discharge: Not Available
FIRE AND EXPLOSION HAZARDS:
Vapors may accumulate in areas with inadequate ventilation possibly forming an explosive atmosphere. Use
adequate ventilation to prevent vapor buildup.
EXTINGUISHING MEDIA:
Water (foam), dry chemical, carbon dioxide.
FIRE FIGHTING INSTRUCTIONS:
If possible, stop flow of hexane. Use water spray to cool surrounding containers. Wear self-contained breathing
apparatus and other protective clothing as required to fight fire.
6. Accidental Release Measures
Evacuate all personnel from affected area. Use appropriate protective equipment. If leak is in user鈥檚 equipment,
be certain to purge piping with inert gas prior to attempting repairs. If leak is in container or container valve,
contact the appropriate emergency telephone number listed in Section 1 or call your closest BOC location.
7. Handling and Storage
Electrical Classifications:
Class 1, Group not specified.
Earth-ground and bond all lines and equipment associated with the hexane system. All electrical equipment
should be non-sparking or explosion proof.
MSDS: G-38
Revised: 6/7/96 Page 3 of 7
PRODUCT NAME: HEXANE
Use only in well-ventilated areas. For gases, valve protection caps must remain in place unless container is
secured with valve outlet piped to use point. Do not drag, slide or roll cylinders. Use a suitable hand truck for
cylinder movement. Use a pressure reducing regulator when connecting cylinder to lower pressure (<3000 psig)
piping or systems. Do not heat cylinder by any means to increase the discharge rate of product from the
cylinder. Use a check valve or trap in the discharge line to prevent hazardous back flow into the system.
Protect cylinders from physical damage. Store in cool, dry, well-ventilated area away from heavily trafficked
areas and emergency exits. Do not allow the temperature where cylinders are stored to exceed 130oF (54oC).
Cylinders should be stored upright and firmly secured to prevent falling or being knocked over. Full and empty
cylinders should be segregated. Use a "first in-first out" inventory system to prevent full cylinders being stored
for excessive periods of time. Post "NO SMOKING OR OPEN FLAMES" signs in the storage area or use area.
There should be no sources of ignition in the storage or use area.
For additional recommendations, consult Compressed Gas Association鈥檚 Pamphlet P-1.
Never carry a compressed gas cylinder or a container of a gas in cryogenic liquid form in an enclosed space such
as a car trunk, van or station wagon. A leak can result in a fire, explosion, asphyxiation or a toxic exposure.
