**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Highly flammable.

Potential Health Effects
Eye:
Causes severe eye irritation. May cause painful sensitization to
light. May cause chemical conjunctivitis and corneal damage.
Skin:
Causes moderate skin irritation. May be harmful if absorbed through
the skin. May cause cyanosis of the extremities.
Ingestion:
May be fatal or cause blindness if swallowed. May cause
gastrointestinal irritation with nausea, vomiting and diarrhea. May
cause systemic toxicity with acidosis. May cause central nervous
system depression, characterized by excitement, followed by headache,
dizziness, drowsiness, and nausea. Advanced stages may cause
collapse, unconsciousness, coma and possible death due to respiratory
failure.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. Causes respiratory tract irritation. May cause narcotic
effects in high concentration. Vapors may cause dizziness or
suffocation.
Chronic:
May cause reproductive and fetal effects. Laboratory experiments
have resulted in mutagenic effects. Animal studies have reported the
development of tumors. Prolonged exposure may cause liver, kidney,
and heart damage.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing
before reuse.
Ingestion:
Call a poison control center. If swallowed, do not induce vomiting
unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. Get medical aid.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively. Persons with skin or eye
disorders or liver, kidney, chronic respiratory diseases, or central
and peripheral nervous sytem diseases may be at increased risk from
exposure to this substance.
Antidote:
Ethanol may inhibit methanol metabolism.

**** SECTION 5 - FIRE FIGHTING MEASURES ****

General Information:
Containers can build up pressure if exposed to heat and/or fire. As
in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Vapors may form an explosive mixture with air.
Vapors can travel to a source of ignition and flash back. Will burn
if involved in a fire. Flammable Liquid. Can release vapors that form
explosive mixtures at temperatures above the flashpoint. Use water
spray to keep fire-exposed containers cool. Containers may explode
in the heat of a fire. May be ignited by heat, sparks, and flame.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. For large fires, use water spray, fog, or
alcohol-resistant foam. Water may be ineffective. Do NOT use
straight streams of water. Cool containers with flooding quantities
of water until well after fire is out.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Remove all sources of ignition.
Use a spark-proof tool. Provide ventilation. A vapor suppressing
foam may be used to reduce vapors. Water spray may reduce vapor but
may not prevent ignition in closed spaces.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Wash thoroughly after handling. Use only in a well-ventilated area.
Use with adequate ventilation. Ground and bond containers when
transferring material. Use spark-proof tools and explosion proof
equipment. Avoid contact with eyes, skin, and clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Keep container tightly closed. Keep away from heat, sparks
and flame. Do not ingest or inhale. Do not pressurize, cut, weld,
braze, solder, drill, grind, or expose empty containers to heat,
sparks or open flames.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Keep from contact
with oxidizing materials. Store in a cool, dry, well-ventilated area
away from incompatible substances. Flammables-area. Do not store
near perchlorates, peroxides, chromic acid or nitric acid.

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****

Engineering Controls:
Use explosion-proof ventilation equipment. Facilities storing or
utilizing this material should be equipped with an eyewash facility
and a safety shower. Use adequate general or local exhaust
ventilation to keep airborne concentrations below the permissible
exposure limits.
