Section 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Highly flammable. Toxic by inhalation and if swallowed. Causes burns.Corrosive.
Potential Health Effects
Eye:
Causes eye burns. May cause painful sensitization to light. May cause blindness. May cause chemical conjunctivitis and corneal damage.
Skin:
Causes skin burns. May be absorbed through the skin. Contact with the skin may have a delayed effect with aching beginning after several hours followed by burns. May cause irritation and dermatitis.
May cause cyanosis of the extremities.
Ingestion:
May be fatal or cause blindness if swallowed. May cause kidney damage. May cause systemic toxicity with acidosis. May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns. 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. Ingestion may produce severe abdominal pain, corrosion of the lips, mouth, tongue, and pharynx, and the vomiting of large pieces of mucosa.
Inhalation:
May cause visual impairment and possible permanent blindness. May cause effects similar to those described for ingestion. May cause burns to the respiratory tract. May cause drowsiness, unconsciousness, and central nervous system depression. Aspiration may lead to pulmonary edema. Vapors may cause dizziness or suffocation. Exposure to the mist may cause multiple small burns with temporary loss of hair. May cause burning sensation in the chest.
Chronic:
Chronic inhalation and ingestion may cause effects similar to those of acute inhalation and ingestion. Effects may be delayed.

Section 4 - FIRST AID MEASURES
Eyes: 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. 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 breathing is difficult, give oxygen. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
Notes to Physician:
Effects may be delayed. Ethanol may inhibit methanol metabolism.
Antidote: Ethanol may inhibit methanol metabolism.
Skin:
Get medical aid immediately. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.

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. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Will burn if involved in a fire. Use water spray to keep fire-exposed containers cool. Containers may explode in the heat of a fire. Flammable liquid and vapor. May be ignited by heat, sparks, and flame. Containers may explode when heated.
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. Use water spray to cool fire-exposed containers. Water may be ineffective. 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. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, observing precautions in the Protective Equipment section. 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:
Remove contaminated clothing and wash before reuse. Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Do not get in eyes, on skin, or on 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. 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.
