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

EMERGENCY OVERVIEW
Highly flammable. Toxic by inhalation, in contact with skin and if
swallowed. Toxic : danger of very serious irreversible effects
through inhalation, in contact with skin and if swallowed.

Potential Health Effects
Eye:
Methanol is a mild to moderate eye irritant. Inhalation, ingestion
or skin absorption of methanol can cause significant disturbances in
vision, including blindness.
Skin:
Causes moderate skin irritation. Harmful if absorbed through the
skin. Prolonged and/or repeated contact may cause defatting of the
skin and dermatitis. Methanol can be absorbed through the skin,
producing systemic effects that include visual disturbances.
Ingestion:
Harmful if swallowed. May be fatal or cause blindness if swallowed.
Aspiration hazard. 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:
Methanol is toxic and can very readily form extremely high vapor
concentrations at room temperature. Inhalation is the most common
route of occupational exposure. At first, methanol causes CNS
depression with nausea, headache, vomiting, dizziness and
incoordination. A time period with no obvious symptoms follows
(typically 8-24 hrs). This latent period is followed by metabolic
acidosis and severe visual effects which may include reduced
reactivity and/or increased sensitivity to light, blurred, double
and/or snowy vision, and blindness. Depending on the severity of
exposure and the promptness of treatment, survivors may recover
completely or may have permanent blindness, vision disturbances
and/or nervous system effects.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Chronic
exposure may cause effects similar to those of acute exposure.
Methanol is only very slowly eliminated from the body. Because of
this slow elimination, methanol should be regarded as a cumulative
poison. Though a single exposure may cause no effect, daily exposures
may result in the accumulation of a harmful amount. Methanol has
produced fetotoxicity in rats and teratogenicity in mice exposed by
inhalation to high concentrations that did not produce significant
maternal toxicity.

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

Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid.
Skin:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
Ingestion:
Potential for aspiration if swallowed. Get medical aid immediately.
Do not induce vomiting unless directed to do so by medical
personnel. Never give anything by mouth to an unconscious person.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Effects may be delayed.
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. During a fire, irritating and highly toxic gases may
be generated by thermal decomposition or combustion. Use water spray
to keep fire-exposed containers cool. Water may be ineffective.
Material is lighter than water and a fire may be spread by the use
of water. Flammable liquid and vapor. Vapors are heavier than air and
may travel to a source of ignition and flash back. Vapors can spread
along the ground and collect in low or confined areas.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. Water may be ineffective. For large fires,
use water spray, fog or alcohol-resistant foam. Do NOT use straight
streams of water.

**** 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. Use water spray to disperse the
gas/vapor. Remove all sources of ignition. 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. Remove contaminated clothing and
wash before reuse. Ground and bond containers when transferring
material. Avoid contact with eyes, skin, and clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Keep container tightly closed. Do not ingest or inhale. Do
not pressurize, cut, weld, braze, solder, drill, grind, or expose
empty containers to heat, sparks or open flames. Use only with
adequate ventilation. Keep away from heat, sparks and flame. Avoid
use in confined spaces. Avoid breathing vapor or mist.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a cool, dry, well-ventilated area away from
incompatible substances. Flammables-area. Keep containers tightly
closed.

**** 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.
Personal Protective Equipment

Eyes:
Wear chemical goggles.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant a respirator's use.
