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

EMERGENCY OVERVIEW
Flammable. Causes severe burns.Corrosive.

Potential Health Effects
Eye:
Causes severe eye burns. May cause irreversible eye injury.
Contact may cause ulceration of the conjunctiva and cornea. Eye
damage may be delayed. May cause painful sensitization to light.
Vapors may cause eye irritation.
Skin:
Causes skin burns. May be absorbed through the skin in harmful
amounts.
Ingestion:
May be fatal or cause blindness if swallowed. May cause systemic
toxicity with acidosis. May cause liver and kidney damage. 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. May cause perforation of the digestive
tract. Causes severe digestive tract burns with abdominal pain,
vomiting, and possible death.
Inhalation:
Irritation may lead to chemical pneumonitis and pulmonary edema.
Causes severe irritation of upper respiratory tract with coughing,
burns, breathing difficulty, and possible coma. May cause visual
impairment and possible permanent blindness. May cause drowsiness,
unconsciousness, and central nervous system depression.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Chronic
inhalation and ingestion may cause effects similar to those of acute
inhalation and ingestion.

**** 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
immediately. Do NOT allow victim to rub eyes or keep eyes closed.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Discard contaminated clothing in a manner which limits
further exposure.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Never give anything by mouth to an
unconscious person. Get medical aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Do NOT use mouth-to-mouth
resuscitation.
Notes to Physician:
Effects may be delayed. Ethanol may inhibit methanol metabolism.

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

General Information:
Containers can build up pressure if exposed to heat and/or fire.
Vapors can travel to a source of ignition and flash back. Flammable
Liquid. Can release vapors that form explosive mixtures at
temperatures above the flashpoint. Use water spray to keep
fire-exposed containers cool. Wear appropriate protective clothing to
prevent contact with skin and eyes. Wear a self-contained breathing
apparatus (SCBA) to prevent contact with thermal decomposition
products. Vapors may be heavier than air. They can spread along the
ground and collect in low or confined areas. Vapors may form an
explosive mixture with air. Containers may explode when heated.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. Use water spray to cool fire-exposed
containers. Water may be ineffective. Do NOT use straight streams of
water. For large fires, use dry chemical, carbon dioxide,
alcohol-resistant foam, or water spray. 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.
Absorb spill using an absorbent, non-combustible material such as
earth, sand, or vermiculite. Do not use combustible materials such
as sawdust. A vapor suppressing foam may be used to reduce vapors.
Use water spray to reduce vapors, do not put water directly on leak,
spill area or inside container.

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

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Ground and bond containers when transferring
material. Do not get in eyes, on skin, or on clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Take precautionary measures against static discharges.
Keep container tightly closed. Keep away from heat, sparks and flame.
Do not ingest or inhale. Use only in a chemical fume hood. 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. Store in a cool, dry,
well-ventilated area away from incompatible substances.

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

Engineering Controls:
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. Use only under a chemical fume hood.
