3. Hazards Identification Overview:
DANGER! EXTREMELY FLAMMABLE LIQUID AND VAPOR. MAY FORM EXPLOSIVE MIXTURES WITH AIR.
HARMFUL OR FATAL IF SWALLOWED. HARMFUL IF INHALED. MAY CAUSE CENTRAL NERVOUS SYSTEM
DAMAGE.
CAUSES
IRRITATION
TO
SKIN,
EYES
AND
RESPIRATORY
TRACT
POTENTIAL HEALTH EFFECTS:
ROUTES OF ENTRY: Inhalation, Ingestion
ACUTE EFFECTS: Possible central nervous system depression. Liquid contact with skin causes irritation,
redness and pain; prolonged contact may lead to drying, dermatitis and the formation of blisters.
Ingestion of the liquid causes gastrointestinal irritation. Irritating to the respiratory tract, eyes, and nose.
Symptoms include dizziness, excitement, incoordination, and vomiting. Loss of consciousness and death
due to respiratory failure. Concentrations between 270 and 400 mg/l may cause narcosis and cardiac
sensitization. May cause nausea, vomiting, pulmonary irritation and bronchial pneumonia with fever and
coughing when aspirated. May cause ventricular fibrillation and kidney, liver and bone marrow damage.
Aspiration is also an asphyxiation hazard.
CHRONIC EFFECTS: Possible dermatitis from skin contact.
MEDICAL CONDITIONS AGGRAVATED BY OVEREXPOSURE: Prolonged exposure may cause skin drying and
dermatitis. Prolonged or repeated inhalation exposure may cause dizziness, weakness, weight loss,
anemia, pain in the limbs and peripheral numbness.
OTHER EFFECTS OF OVEREXPOSURE: None found.
CARCINOGENICITY (US ONLY): No chronic effects data given in the Registry of Toxic Effects of Chemical
Substances (RTECS) or Sax, Dangerous Priorities of Industrial Materials
NTP – No
IARC MONOGRAPHS - No
OSHA REGULATED – No
4. First Aid Measures:
INHALATION: Immediately remove victim to fresh air. If breathing is difficult, give oxygen. If breathing has
stopped, give artificial respiration. Get medical attention immediately.
EYE CONTACT: Do not allow victim to rub or keep eyes tightly shut. Immediately flush eyes, including
under the eyelids, gently but thoroughly with plenty of running water for at least 15 minutes. Get medical
attention immediately.
SKIN CONTACT: Immediately flush with copious amounts of soapy water for at least 15 minutes while
removing contaminated clothing. For reddened or irritated skin, consult a physician.
INGESTION: Aspiration hazard. Never give anything by mouth to an unconscious person. Contact a poison
control center. Unless the poison control center advises otherwise, do not give any liquids. DO NOT
INDUCE VOMITING IN EVENT OF EXPOSURE, CONSULT A PHYSICIAN
NOTE TO PHYSICIAN: Epinephrine and other sympathomimetic drugs may initiate cardiac arrhythmias in
persons exposed to high concentrations of hydrocarbon solvents (e.g., in enclosed spaces or with
deliberate abuse). The use of other drugs with less arrhythmogenic potential should be considered. If
sympathomimetic drugs are administered, observe for the development of cardiac arrhythmias.
5. Fire Fighting Measures
Fire:
Flash point:
Autoignition temperature:
Flammable limits in air % by volume:
< -40oC (< -40oF) CC
284oC (544oF)
LEL: 1.4%; UEL 8.0%
Extremely flammable Liquid and Vapor Dangerous fire hazard when exposed to heat, flame or other
ignition source. Vapors may travel long distances to an ignition source where flashback can occur.
Explosion: Above the flash point, explosive vapor-air mixtures may be formed. Contact with strong
oxidizers may cause fire. Sealed containers may rupture when heated. Vapors can flow along surfaces
to distant ignition source and flash back. Sensitive to static discharge.
Fire Extinguishing Media: Dry chemical, foam or carbon dioxide. Water may be ineffective. Water spray
may be used to keep fire exposed containers cool, dilute spills to nonflammable mixtures, protect
personnel attempting to stop leak and disperse vapors.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved selfcontained breathing apparatus with full face piece operated in the pressure demand or other positive
pressure mode. This highly flammable liquid must be kept from sparks, open flame, hot surfaces, and all
sources of heat and ignition.
6. Accidental Release Measures
Ventilate area of leak or spill. Remove all sources of ignition. Wear appropriate personal protective
equipment as specified in Section 8. Isolate hazard area. Keep unnecessary and unprotected personnel
from entering. Ensure all sources of ignition as kept out of the affected area.Contain and recover liquid
when possible. Use non-sparking tools and equipment. Collect liquid in an appropriate container or absorb
with an inert material (e. g., vermiculite, dry sand, earth), and place in a chemical waste container. Do not
use combustible materials, such as saw dust. Do not flush to sewer! If a leak or spill has not ignited, use
water spray to disperse the vapors, to protect personnel attempting to stop leak, and to flush spills away
from exposure.
7. Handling and Storage
Protect against physical damage. Store in a cool, dry well-ventilated location, away from direct sunlight
and any area where the fire hazard may be acute. Store in tightly closed containers (preferably under
nitrogen atmosphere). Outside or detached storage is preferred. Inside storage should be in a standard
flammable liquids storage room or cabinet. Separate from oxidizing materials. Containers should be
bonded and grounded for transfers to avoid static sparks. Storage and use areas should be No Smoking
areas. Use non-sparking type tools and equipment. Containers of this material may be hazardous when
empty since they retain product residues (vapors, liquid); observe all warnings and precautions listed for
the product. Recommended that explosion proof equipment be used. Avoid high temperatures.
8. Exposure Controls/Personal Protection
Airborne exposure limits: OSHA Permissible Exposure Limit (PEL) 1000 ppm (TWA)
ACGIH Threshold Limit Value (TLV) : 600 ppmNIOSH (REL): alkanes TWA 350
mg/m3, ceiling level 1800 mg/m3
Ventilation System: A system of local and/or general exhaust is recommended to keep employee
exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it
can control the emissions of the contaminant at its source, preventing dispersion of it into the general
work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended
Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved): If the exposure limit is exceeded, wear a supplied air, full- face
piece respirator, air-lined hood, or full-face piece self-contained breathing apparatus. This substance has
unknown warning properties.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles and/or a full face shield where splashing is possible.
Maintain eye wash fountain and quick-drench facilities in work area.
