ROUTE(S) of Entry
Inhalation A single prolonged (hours) inhalation exposure is not likely to cause adverse
effects. Mists in high concentrations may cause irritation of nose and throat, cause
headache, nausea or drowsiness. Prolonged or repeated exposure may result in the
absorption of potentially harmful amounts of material.
Skin: A single prolonged exposure is not likely to result in the material being absorbed
through skin in harmful amounts. Repeated exposure may cause slight flaking,
tenderness and softening of skin.
Ingestion: Single dose oral toxicity is low. If more than several mouthfuls are swallowed,
abdominal discomfort, nausea or diarrhea may occur
.
Eyes: May cause minor irritation of eyes in some individuals. Corneal injury is unlikely.
Target Organs: None known
Effect of overexposure: Repeated excessive ingestion may cause central nervous system effects. No
carcinogenic effects have been seen in long-term animal studies. Birth defects are
unlikely. Exposure having no adverse effects on the mother should have no effect

Indication of any immediate medical attention and special treatment needed
Notes to physician: No specific antidote. Treatment of exposure should be directed at the control of
symptoms and the clinical condition of the patient.
5. FIREFIGHTING MEASURES
Suitable extinguishing media: Water fog or fine spray. Dry chemical fire extinguishers. Carbon
dioxide fire extinguishers. Foam. Alcohol resistant foams (ATC type) are preferred. General purpose
synthetic foams (including AFFF) or protein foams may function, but will be less effective.
Unsuitable extinguishing media: Do not use direct water stream. May spread fire.
Special hazards arising from the substance or mixture
Hazardous combustion products: During a fire, smoke may contain the original material in addition
to combustion products of varying composition which may be toxic and/or irritating. Combustion
products may include and are not limited to: Carbon monoxide. Carbon dioxide.
Unusual Fire and Explosion Hazards: Container may rupture from gas generation in a fire situation.
Violent steam generation or eruption may occur upon application of direct water stream to hot liquids.
Advice for firefighters
Fire Fighting Procedures: Keep people away. Isolate fire and deny unnecessary entry. Use water
spray to cool fire exposed containers and fire affected zone until fire is out and danger of reignition has
passed. Fight fire from protected location or safe distance. Consider the use of unmanned hose
holders or monitor nozzles. Immediately withdraw all personnel from the area in case of rising sound
from venting safety device or discoloration of the container. Burning liquids may be extinguished by
dilution with water. Do not use direct water stream. May spread fire. Move container from fire area if
this is possible without hazard. Burning liquids may be moved by flushing with water to protect
personnel and minimize property damage.
Special protective equipment for firefighters: Wear positive-pressure self-contained breathing
apparatus (SCBA) and protective fire fighting clothing (includes fire fighting helmet, coat, trousers,
boots, and gloves). If protective equipment is not available or not used, fight fire from a protected
location or safe distance.
6. ACCIDENTAL RELEASE MEASURES
Personal precautions, protective equipment and emergency procedures: Use appropriate safety
equipment. For additional information, refer to Section 8, Exposure Controls and Personal Protection.
Environmental precautions: Prevent from entering into soil, ditches, sewers, waterways and/or
groundwater. See Section 12, Ecological Information.

Methods and materials for containment and cleaning up: Small spills: Absorb with materials such
as: Cat litter. Sawdust. Vermiculite. Zorb-all®. Collect in suitable and properly labeled containers.
Large spills: Dike area to contain spill. Recover spilled material if possible. See Section 13, Disposal
Considerations, for additional information.
7. HANDLING AND STORAGE
Precautions for safe handling: No special precautions required. Keep container closed. See
Section 8, EXPOSURE CONTROLS AND PERSONAL PROTECTION.
Spills of these organic materials on hot fibrous insulations may lead to lowering of the autoignition
temperatures possibly resulting in spontaneous combustion.
Conditions for safe storage: Do not store in: Galvanized steel. Opened or unlabeled containers.
Store in original unopened container. See Section 10 for more specific information. Additional storage
and handling information on this product may be obtained by calling your sales or customer service
contact.

Consult local authorities for recommended exposure limits.
Exposure controls
Engineering controls: Use local exhaust ventilation, or other engineering controls to maintain
airborne levels below exposure limit requirements or guidelines. If there are no applicable exposure
limit requirements or guidelines, general ventilation should be sufficient for most operations. Local
exhaust ventilation may be necessary for some operations.
Individual protection measures
Eye/face protection: Use safety glasses (with side shields).
Skin protection
Hand protection: Use gloves chemically resistant to this material when prolonged or
frequently repeated contact could occur. Examples of preferred glove barrier
materials include: Butyl rubber. Natural rubber (“latex”). Neoprene. Nitrile/butadiene
rubber (“nitrile” or “NBR”). Polyethylene. Ethyl vinyl alcohol laminate (“EVAL”).
Polyvinyl alcohol (“PVA”). Polyvinyl chloride (“PVC” or “vinyl”). NOTICE: The
selection of a specific glove for a particular application and duration of use in a
workplace should also take into account all relevant workplace factors such as, but
not limited to: Other chemicals which may be handled, physical requirements
(cut/puncture protection, dexterity, thermal protection), potential body reactions to
glove materials, as well as the instructions/specifications provided by the glove
supplier.
Other protection: Wear clean, body-covering clothing.

Respiratory protection: Respiratory protection should be worn when there is a potential to
exceed the exposure limit requirements or guidelines. If there are no applicable exposure limit
requirements or guidelines, wear respiratory protection when adverse effects, such as
respiratory irritation or discomfort have been experienced, or where indicated by your risk
assessment process. In misty atmospheres, use an approved particulate respirator.
The following should be effective types of air-purifying respirators: Organic vapor cartridge
with a particulate pre-filter.
