Potential Health Effects

----------------------------------

Inhalation:
Inhalation may cause symptoms of intoxication and peripheral nerve disorders and central nervous
system depression. Symptoms of overexposure include loss of appetite, muscle weakness,
impairment of motor action, dizziness and drowsiness. May also cause throat irritation.

Ingestion:
Local irritation with burning sensation in mouth, esophagus, and stomach. Vomiting, blurred vision,
and diarrhea may also occur. Cases of chemical pneumonia have been reported from ingestion of
this substance. Nervous system disorders paralleling those from inhalation exposure may also
occur.

Skin Contact:
May cause irritation. The liquid acts as a defatting agent on the skin.

Eye Contact:
Vapors may cause irritation. Splashes may cause redness and pain.

Chronic Exposure:
Prolonged overexposure may cause drying and cracking of the skin and associated dermatitis. No
chronic systematic effects have been reported from widespread industrial use.

Aggravation of Pre-existing Conditions:

Persons with pre-existing skin disorders or eye problems, or impaired liver, kidney or respiratory
function may be more susceptible to the effects of the 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, 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.

PETROLEUM ETHER, 50-110C file:///D|/Documents/Oilphase Stuff/Oilpha...ngerous Goods/MSDS sheets/petether1700.htm

Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated
clothing and shoes. Call a physician, immediately. Wash clothing 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.

Note to Physician:
Monitor all significant inhalations and all ingestions for signs of toxicity and development of
pulmonary edema for at least 6 hours.

5. Fire Fighting Measures

Fire:
Flash point: -45C (-49F) CC Autoignition temperature: 287C (549F) Flammable limits in air % by
volume: lel: 1; uel: 5.9 Extremely Flammable Liquid and Vapor! Vapor may cause flash fire.
Dangerous fire hazard when exposed to heat or flame. Contact with strong oxidizers may cause
fire.

Explosion:
Above flash point, vapor-air mixtures are explosive within flammable limits noted above. Sealed
containers may rupture when heated. Sensitive to static discharge.

Fire Extinguishing Media:

Dry chemical, foam or carbon dioxide. Water may be ineffective. Do not allow water runoff to
enter sewers or waterways.

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. 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. 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! 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. J. T. Baker SOLUSORB(tm) solvent adsorbent is recommended for spills of this
product.

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. Isolate from incompatible substances. 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. DANGER! DO NOT OPEN Unless Contents
Are At Room temperature (72F) or Below. Allow at least 24 hours for material to cool to room
temperature before opening container.

8. Exposure Controls/Personal Protection

Airborne Exposure Limits:
For VM&P Naphtha: - OSHA Permissible Exposure Limit (PEL): 300 ppm (TWA), 400 ppm
(STEL) - ACGIH Threshold Limit Value (TLV): 300 ppm (TWA), A3 - Animal Carcinogen. For
Petroleum Distillates (naphtha): - OSHA Permissible Exposure Level (PEL): 500 ppm (TWA)

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, 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.
