Potential Health Effects
----------------------------------
Inhalation:
May cause symptoms similar to those of ingestion. High concentrations may
cause dizziness, lack of coordination, and narcosis. Concentrations of
about 16,000 ppm may cause respiratory arrest.
Ingestion:
May cause nausea, vomiting, pulmonary irritation, edema, bloody sputum, and
bronchial pneumonia with fever and coughing when aspirated. If large doses
(> 1ml/kg) are ingested and retained symptoms of central nervous system
depression may occur and include shallow respiration, unconsciousness, and
convulsions. May cause ventricular fibrillation, kidney, liver and bone
marrow damage.
Skin Contact:
Causes skin irritation. May cause an allergic dermatitis.
Eye Contact:
Causes irritation; symptoms including redness, itching, and pain.
Chronic Exposure:
Prolonged or repeated skin contact may cause dermatitis.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or impaired pulmonary function may
be more susceptible to the 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. Call a physician.
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:
Remove any contaminated clothing. Wash skin with soap or mild detergent
and water for at least 15 minutes. Wash clothes before reuse. Get medical
attention if irritation develops or persists.
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: -12C (10F) CC
Autoignition temperature: 415C (779F)
Flammable limits in air % by volume:
lel: 1.1; uel: 6.0
Extremely Flammable Liquid and Vapor! Vapor may cause flash fire.
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.
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! Have foam or dry powder extinguisher on hand.
Small spills will evaporate. 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.
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. Do Not attempt to clean empty containers since residue is
difficult to remove. Do not pressurize, cut, weld, braze, solder, drill,
grind or expose such containers to heat, sparks, flame, static electricity
or other sources of ignition: they may explode and cause injury or death.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
-OSHA Permissible Exposure Limit (PEL): 500 ppm (TWA) for (Petroleum Distillates)
-NIOSH (REL): 10Hr.TWA, 350mg/m3, 1800 mg/m3 15min. Ceiling for (Refined Petroleum Distillates)
-ACGIH Threshold Limit Value (TLV): 300 ppm (TWA) for (iso-octane).
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):
For conditions of use where exposure to the substance is apparent and
engineering controls are not feasble, 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. Maintain eye wash fountain and quick-drench
facilities in work area.
