Potential Health Effects
----------------------------------
Inhalation: Causes irritation to the respiratory tract. Symptoms may include coughing, shortness of
breath. Exposure to high concentrations may cause numbness, nausea, headache, CNS depression and
vomiting.
Ingestion: Harmful if swallowed. Direct aspiration into the lungs may cause chemical pneumonitis and
may cause lung damage. Causes irritation to the gastrointestinal tract. Symptoms may include nausea,
vomiting and diarrhea.
Skin Contact: Causes irritation to skin. Symptoms include redness, itching, and pain. May cause
dermatitis.
Eye Contact: Causes irritation, redness, and pain. Contact may cause eye damage.
Chronic Exposure: Prolonged or repeated skin contact may produce a skin infection.
Aggravation of Pre-existing Conditions: The use of alcohol beverages may enhance the toxic effects of
this substance.
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, 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: Immediately flush skin with plenty of water for at least 15 minutes. Remove
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: 58oC (136oF) CC
Autoignition temperature: 250oC (482oF)
Flammable limits in air % by volume:
lel: 0.7; uel: 4.9
Flammable Liquid and Vapor!
Explosion: Above flash point, vapor-air mixtures are explosive within flammable limits noted above.
Sealed containers may rupture when heated. Contact with strong oxidizers may cause fire. Sensitive to
static discharge.
Fire Extinguishing Media: Dry chemical, alcohol foam or carbon dioxide. Do not use a solid stream of
water, since the stream will scatter and spread the fire.
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. Vapors can flow along surfaces to distant ignition source and flash back.

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
Keep packed under nitrogen. 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: 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.

12. Ecological Information
Environmental Fate: When released into the soil, this material may biodegrade to a moderate extent.
When released to water, this material is expected to quickly evaporate. 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.
Environmental Toxicity: No information found.
