Section 3 - Hazards Identification
Appearance: clear, colorless liquid. Flash Point: -49 deg C.
Danger! Extremely flammable liquid and vapor.
Vapor may cause flash fire. Breathing vapors may cause drowsiness
and dizziness. Causes eye and skin irritation. Repeated exposure may
cause skin dryness or cracking. Aspiration hazard if swallowed. Can
enter lungs and cause damage. May cause respiratory tract irritation.
Target Organs: Central nervous system,
respiratory system, eyes, skin.
Potential Health Effects
Causes eye irritation.
Causes skin irritation. Repeated or prolonged exposure may cause
drying and cracking of the skin.
Volunteers suffered from painful burning sensations, accompanied by
itching, after topical application of pentane; after 5 hours,
blisters formed on the treated areas.
May cause central nervous system depression, characterized by
excitement, followed by headache, dizziness, drowsiness, and nausea.
Advanced stages may cause collapse, unconsciousness, coma and
possible death due to respiratory failure. Aspiration of material
into the lungs may cause chemical pneumonitis, which may be fatal.
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. May cause respiratory tract irritation. Vapors may cause
dizziness or suffocation.
Prolonged or repeated skin contact may cause defatting and
dermatitis. Chronic exposure to vapors may produce polyneuropathy.
The possibility that chronic exposure to very high concentrations may
lead to polyneuropathy cannot be ruled out altogether, despite the
substantially lower toxicity of pentane, in comparison with hexane
and its neurotoxicity.
Section 4 - First Aid Measures
In case of contact, immediately flush eyes with plenty of water for a
t least 15 minutes. Get medical aid.
In case of contact, flush skin with plenty of water. Remove
contaminated clothing and shoes. Get medical aid if irritation
develops and persists. Wash clothing before reuse.
Potential for aspiration if swallowed. Get medical aid immediately.
Do not induce vomiting unless directed to do so by medical
personnel. Never give anything by mouth to an unconscious person. If
vomiting occurs naturally, have victim lean forward.
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
Containers can build up pressure if exposed to heat and/or fire. As
in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Vapors may form an explosive mixture with air. Use
water spray to keep fire-exposed containers cool. Extremely flammable
liquid and vapor. Vapor may cause flash fire. Vapors are heavier than
air and may travel to a source of ignition and flash back. Vapors can
spread along the ground and collect in low or confined areas.
Sensitive to static discharge.
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. For large fires, use water spray, fog, or
alcohol-resistant foam. This material is lighter than water and
insoluble in water. The fire could easily be spread by the use of
water in an area where the water cannot be contained. Do NOT use
straight streams of water.
Flash Point: -49 deg C ( -56.20 deg F)
Autoignition Temperature: 260 deg C ( 500.00 deg F)
Explosion Limits, Lower:1.5
(estimated) Health: 1; Flammability: 4; Instability: 0
Section 6 - Accidental Release Measures
General Information: Use proper personal protective equipment as indicated
in Section 8.
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Remove all sources of ignition.
Use a spark-proof tool. Provide ventilation. A vapor suppressing
foam may be used to reduce vapors.
Section 7 - Handling and Storage
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Ground and bond containers when transferring
material. Use spark-proof tools and explosion proof equipment. Avoid
contact with eyes, skin, and clothing. Empty containers retain
product residue, (liquid and/or vapor), and can be dangerous. Take
precautionary measures against static discharges. Do not pressurize,
cut, weld, braze, solder, drill, grind, or expose empty containers to
heat, sparks or open flames. Use only with adequate ventilation. Keep
away from heat, sparks and flame. Avoid breathing vapor or mist.
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Keep from contact
with oxidizing materials. Store in a cool, dry, well-ventilated area
away from incompatible substances. Flammables-area.
Section 8 - Exposure Controls, Personal Protection
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits. Ventilation fans and other electrical
service must be non-sparking and have an explosion-proof design.

irritation or other symptoms are experienced.

n-Hexane is a mild irritant and CNS depressant in acute
exposure, but its principal effects are damage to the
sensory and motor peripheral nerves, particularly in
chronic exposure.Because of the otherwise substantially
lower toxicity of pentane, in comparison with hexane, it
is believed that such effects, if they occur, would require
gross exposures, & the 600-ppm TLV-TWA should minimize
potential for development of axonopathies.

No data available.
Photolysis or hydrolysis of n-pentane is not expected to be important
in soils. The biodegradation of n-pentane may occur in soils;
however, primarily volatilization and to some extent adsorption are
expected to be far more important fate processes. A calculated Koc
range of 580 to 1600 indicates a low mobility class for n-pentane in
soils. Based upon an estimated Henry's Law Constant of 1.26 atm-cu
m/mole, n-pentane is expected to rapidly volatilize from surface
Based on a vapor pressure of 514 mm Hg at 25°C, n-pentane is expected
to exist entirely in the vapor phase in ambient air. n-Pentane does
not absorb UV light in the environmentally significant range, >290 nm
and probably will not undergo direct photolysis in the atmosphere.
Based upon a water solubility of 38.5 mg/l at 25°C and a log Kow of
3.39, the bioconcentration factor (log BCF) for n-pentane has been
calculated to be 1.90 and 2.35, respectively, from recommended
regression derived equations. These BCF values are not indicative of
important bioconcentration in aquatic organisms.
Section 13 - Disposal Considerations
Chemical waste generators must determine whether a discarded chemical is classified
as a hazardous waste.
US EPA guidelines for the classification determination are listed in 40 CFR Parts 261.3.
Additionally, waste generators must consult state and local hazardous waste regulations to
ensure complete and accurate classification.
