Potential Health Effects
----------------------------------

Inhalation:
Inhalation of vapors can irritate the nose,
throat, and upper respiratory passages. Higher concentrations have a narcotic
effect and may cause headache, nausea, vomiting, dizziness, double vision,
shortness of breath, and delirium. In severe cases, inhalation may be fatal.
May cause pulmonary edema, a medical emergency. May cause heart effects.

Ingestion:
Moderately toxic by ingestion, can cause headache,
nausea, delirium and methemoglobin formation in the blood. Other symptoms may
parallel those from inhalation exposure. Vomiting may cause aspiration into
lungs and result in chemical pnuemonia.
Skin Contact:
Skin
contact causes irritations and possibly burns if contact is repeated or
prolonged. May be absorbed through the skin.
Eye Contact:

Vapors cause severe irritation. Symptoms may include tearing, pain,
redness, swelling. Liquid contact causes severe irritation and possible burns.

Chronic Exposure:
Repeated inhalation of aerosols may result in
lung and kidney injury. Chronic exposure may cause skin effects.

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. Get medical
attention.
Ingestion:
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: 33C (91F) CC
Autoignition
temperature: 300C (572F)
Flammable limits in air % by volume:
lel: 1.2;
uel: 10.0
Listed fire data is for amyl alcohol (CAS 71-41-0). Flammable.
Upper explosive limit is for 100C (212F). Contact with strong oxidizers may
cause 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. Sensitive to static
discharge.
Fire Extinguishing Media:
Dry chemical, foam or
carbon dioxide. Water spray may be used to keep fire exposed containers cool.
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! 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® 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. 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:
- AIHA Workplace
Environmental Exposure Level (WEEL):
100 ppm (360 mg/m3), 8-hour, TWA

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. Use
explosion-proof equipment.
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 and/or a
full face shield where splashing is possible. Maintain eye wash fountain and
quick-drench facilities in work area.
