Potential Health Effects
----------------------------------
Inhalation:
Inhalation of vapors irritates the respiratory
tract. At room temperature the substance has such a low vapor pressure that
inhalation of the vapor is unlikely.
Ingestion:
Toxic.
Swallowing may cause sore throat, abdominal pain, diarrhea, and nervous system
effects. If substance enters the lungs (Aspiration), there is a risk of
pneumonia.
Skin Contact:
Causes irritation with redness and
pain. May be absorbed through the skin.
Eye Contact:
Causes eye
irritation with redness and pain.
Chronic Exposure:
Chronic
exposure may cause kidney effects.
Aggravation of Pre-existing
Conditions:
No information found.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give
artificial respiration. If breathing is difficult, give oxygen. Get medical
attention.
Ingestion:
Aspiration hazard. If swallowed, DO NOT
INDUCE VOMITING. Give large quantities of water. Never give anything by mouth
to an unconscious person. Get medical attention immediately.
Skin
Contact:
Immediately flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Get medical attention.
Wash clothing before reuse. Thoroughly clean shoes before reuse.
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: 76C (169F) CC
Combustible Liquid
and Vapor!
Explosion:
Above the flash point, explosive
vapor-air mixtures may be formed.
Fire Extinguishing Media:
Water spray, dry chemical, alcohol foam, or carbon dioxide. Water may be
ineffective.
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.
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!
7. Handling and Storage
Protect against physical damage. Outside or detached storage is
preferred. Inside storage should be in a standard flammable liquids storage
room or cabinet. Separate from oxidizing materials. Storage and use areas
should be No Smoking areas. 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:
None established.
Ventilation System:
A system of local and/or general exhaust is
recommended to keep employee exposures as low as possible. 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):
For conditions of use
where exposure to the substance is apparent, consult an industrial hygienist.
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.

13. Disposal Considerations
Whatever cannot be saved for recovery or recycling should be
managed in an appropriate and approved waste facility. Although not a listed
RCRA hazardous waste, this material may exhibit one or more characteristics of
a hazardous waste and require appropriate analysis to determine specific
disposal requirements. Processing, use or contamination of this product may
change the waste management options. State and local disposal regulations may
differ from federal disposal regulations. Dispose of container and unused
contents in accordance with federal, state and local requirements.
