Potential Health Effects
----------------------------------
Inhalation:
Causes irritation to the respiratory tract. Symptoms may include coughing,
shortness of breath. High concentrations have a narcotic effect.
Ingestion:
May produce abdominal pain, nausea. Aspiration into lungs can produce
severe lung damage and is a medical emergency. Other symptoms expected to
parallel inhalation.
Skin Contact:
Causes irritation to skin. Symptoms include redness, itching, and pain.
Eye Contact:
Causes irritation, redness, and pain.
Chronic Exposure:
Chronic exposure may cause skin effects.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems, or impaired
liver, kidney or respiratory function may be more susceptible to the
effects of the substance.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Call a physician.
Ingestion:
Aspiration hazard. If swallowed, vomiting may occur spontaneously, but DO
NOT INDUCE. If vomiting occurs, keep head below hips to prevent aspiration
into lungs. Never give anything by mouth to an unconscious person. Call a
physician immediately.
Skin Contact:
In case of contact, immediately flush skin with plenty of soap and water
for at least 15 minutes. Remove contaminated clothing and shoes. Wash
clothing before reuse. Call a physician.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes,
lifting lower and upper eyelids occasionally. Get medical attention
immediately.
5. Fire Fighting Measures
Fire:
Flash point: -20C (-4F) CC
Autoignition temperature: 245C (473F)
Flammable limits in air % by volume:
lel: 1.3; uel: 8.0
Extremely Flammable.
Explosion:
Above flash point, vapor-air mixtures are explosive within flammable limits
noted above. Vapors can flow along surfaces to distant ignition source and
flash back. Sealed containers may rupture when heated. Contact with strong
oxidizers may cause fire. 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
self-contained breathing apparatus with full facepiece 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. 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 exposures. US Regulations (CERCLA) require
reporting spills and releases to soil, water and air in excess of
reportable quantities. The toll free number for the US Coast Guard National
Response Center is (800) 424-8802.
J. T. Baker SOLUSORB(tm) solvent adsorbent is recommended for spills of
this product.
7. Handling and Storage
Protect against physical damage. Store in a cool, dry well-ventilated
location, away from any area where the fire hazard may be acute. Outside or
detached storage is preferred. Separate from incompatibles. 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, including explosion proof ventilation. 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.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
-OSHA Permissible Exposure Limit (PEL): 300 ppm (TWA)
-ACGIH Threshold Limit Value (TLV): 300 ppm (TWA)
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, a full facepiece respirator with organic
vapor cartridge may be worn up to 50 times the exposure limit or the
maximum use concentration specified by the appropriate regulatory agency or
respirator supplier, whichever is lowest. For emergencies or instances
where the exposure levels are not known, use a full-facepiece
positive-pressure, air-supplied respirator. WARNING: Air purifying
respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat,
apron or coveralls, as appropriate, to prevent skin contact.
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.

Environmental Fate:
When released into the soil, this material may biodegrade to a moderate
extent. When released into the soil, this material is expected to leach
into groundwater. When released into the soil, this material is expected to

quickly evaporate. This material has a log octanol-water partition
coefficient of greater than 3.0. This material may bioaccumulate to some
extent. When released into the air, this material is expected to be readily
degraded by reaction with photochemically produced hydroxyl radicals. When
