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

Inhalation:
A slight irritant to the mucous membranes.
Toxic effects exerted upon nervous system, particularly the optic nerve. Once
absorbed into the body, it is very slowly eliminated. Symptoms of overexposure
may include headache, drowsiness, nausea, vomiting, blurred vision, blindness,
coma, and death. A person may get better but then worse again up to 30 hours
later.
Ingestion:
Toxic. Symptoms parallel inhalation. Can
intoxicate and cause blindness. Usual fatal dose: 100-125 milliliters.

Skin Contact:
Methyl alcohol is a defatting agent and may cause
skin to become dry and cracked. Skin absorption can occur; symptoms may
parallel inhalation exposure.
Eye Contact:
Irritant. Continued
exposure may cause eye lesions.
Chronic Exposure:
Marked
impairment of vision has been reported. Repeated or prolonged exposure may
cause skin irritation.
Aggravation of Pre-existing Conditions:

Persons with pre-existing skin disorders or eye problems or impaired liver
or kidney 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 immediately.
Ingestion:
Induce vomiting immediately
as directed by medical personnel. 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: 12C (54F) CC
Autoignition
temperature: 464C (867F)
Flammable limits in air % by volume:
lel: 6.0;
uel: 36
Flammable Liquid and Vapor!
Explosion:
Above flash
point, vapor-air mixtures are explosive within flammable limits noted above.
Moderate explosion hazard and dangerous fire hazard when exposed to heat,
sparks or flames. Sensitive to static discharge.
Fire Extinguishing
Media:
Use alcohol foam, dry chemical or carbon dioxide. (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. Use water spray to blanket fire, cool fire exposed containers, and to
flush non-ignited spills or vapors away from fire. 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. 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.

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.
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:
For Methyl Alcohol:
- OSHA
Permissible Exposure Limit (PEL):
200 ppm (TWA)
- ACGIH Threshold Limit
Value (TLV):
200 ppm (TWA), 250 ppm (STEL) skin
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. Use
explosion-proof equipment.
Personal Respirators (NIOSH Approved):

If the exposure limit is exceeded and engineering controls are not
feasible, wear a supplied air, full-facepiece respirator, airlined hood, or
full-facepiece self-contained breathing apparatus. Breathing air quality must
meet the requirements of the OSHA respiratory protection standard
(29CFR1910.134). This substance has poor warning properties.
Skin
Protection:
Rubber or neoprene gloves and additional protection
including impervious boots, apron, or coveralls, as needed in areas of unusual
exposure.
Eye Protection:
Use chemical safety goggles. Maintain
eye wash fountain and quick-drench facilities in work area.
