**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes burns. Limited evidence of a carcinogenic effect.
Potential Health Effects
Eye:
Causes eye burns.
Skin:
Causes skin burns. May be harmful if absorbed through the skin.
Ingestion:
Causes gastrointestinal tract burns. May be harmful if swallowed.
Inhalation:
Causes chemical burns to the respiratory tract. May be harmful if
inhaled.
Chronic:
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.
**** 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.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes.
Ingestion:
Get medical aid immediately. Do NOT induce vomiting. If conscious
and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
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.
Notes to Physician:
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Contact with water liberates highly flammable
gases.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or chemical foam.
**** 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.
Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Do not breathe dust, vapor, mist, or gas. Do not
get in eyes, on skin, or on clothing. Use only in a chemical fume
hood.
Storage:
Store in a cool, dry place. Store in a tightly closed container.
Corrosives area. Store protected from moisture. Keep away from
acidic, alkaline, combustible and oxidizing materials.
**** 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
ventilation to keep airborne concentrations low.
