Toxicity
Inhalation:
Inhalation may cause irritation of the upper respiratory tract. Symptoms of overexposure may include fatigue,
confusion, headache, dizziness and drowsiness. Peculiar skin sensations (e. g. pins and needles) or numbness
may be produced. Very high concentrations may cause unconsciousness and death.
Ingestion:
Swallowing may cause abdominal spasms and other symptoms that parallel over-exposure from inhalation.
Aspiration of material into the lungs can cause chemical pneumonitis, which may be fatal.
Skin Contact:
Causes irritation. May be absorbed through skin.
Eye Contact:
Causes severe eye irritation with redness and pain.
Chronic Exposure:
Reports of chronic poisoning describe anemia, decreased blood cell count and bone marrow hypoplasia. Liver
and kidney damage may occur. Repeated or prolonged contact has a defatting action, causing drying, redness,
dermatitis. Exposure to toluene may affect the developing fetus.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or impaired liver or kidney function may be more susceptible to the
effects of this substance. Alcoholic beverage consumption can enhance the toxic effects of this substance.
4. First Aid Measures
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
CALL A PHYSICIAN IMMEDIATELY.
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. If vomiting occurs, keep head
below hips to prevent aspiration into lungs.
Skin Contact:
In case of contact, immediately flush skin with plenty of soap and water for at least 15 minutes while removing
contaminated clothing and shoes. Wash clothing before reuse. Call a physician immediately.
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 and Explosion Hazard: Dangerous fire hazard when exposed to heat, flame, or oxidizers. Moderate
explosion hazard when exposed to flame or ignition source.
Vapors are heavier than air and may travel a considerable distance to a source of ignition and flash back.
Vapor-Air mixtures are explosive above the flash point
250C
Flash Point:
Upper Explosion Limit: 7.1%
Lower Explosion Limit: 1.3%
Flammability Class (OSHA): IB
Fire Fighting Media: Dry chemical, carbon dioxide, water or foam.
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. Water
spray may be used to keep fire exposed containers cool.
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.
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):
200 ppm (TWA); 300 ppm (acceptable ceiling conc.); 500 ppm (maximum conc.).
- ACGIH Threshold Limit Value (TLV):
50 ppm (TWA) skin, A4 - Not Classifiable as a Human Carcinogen.
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 and engineering controls are not feasible, a half-face organic vapor respirator
may be worn for up to ten times the exposure limit, or the maximum use concentration specified by the
appropriate regulatory agency or respirator supplier, whichever is lowest. A full-face piece organic vapor
respirator 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-face piece 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.
9. Disposal Considerations
Whatever cannot be saved for recovery or recycling should be handled as hazardous waste and sent to a RCRA
approved incinerator or disposed in a RCRA approved waste facility. 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.
10. Other Precautions
Precautions:
Keep away from heat, sparks and flame.
Keep container closed.
Use only with adequate ventilation.
Wash thoroughly after handling.
Avoid breathing vapor.
Avoid contact with eyes, skin and clothing.
First Aid:
Aspiration hazard. If swallowed, DO NOT INDUCE VOMITING. Give large quantities of water. Never give
anything by mouth to an unconscious person. If vomiting occurs, keep head below hips to prevent aspiration
into lungs. If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult,
give oxygen. In case of contact, immediately flush eyes or skin with plenty of water for at least 15 minutes.
Remove contaminated clothing and shoes. Wash clothing before reuse. In all cases call a physician
immediately.
