EMERGENCY OVERVIEW
------------------------------
POISON! DANGER! Vapor harmful. May be fatal or cause blindness if swallowed. Harmful if inhaled or absorbed through skin. Cannot be made nonpoisonous. Flammable liquid and vapor. Causes irritation to skin, eyes and respiratory tract. Affects central nervous system and liver.
Health Rating: 3 - severe (poison) flammability Rating: 4 - extreme (flammable) reactivity Rating: 1 - slight contact Rating: 1 - slight lab protective equip: goggles & shield; lab coat & apron; vent hood; proper gloves; class b extinguisher storage color Code: red (flammable)
------------------------------
Potential Health Effects
Inhalation: A slight irritant to the mucous membranes. Toxic effects exerted upon nervous system, particularly the optic nerve. Once absorbed into the body, it is very slowly eliminated. Symptoms of overexposure may include headache, drowsiness, nausea, vomiting, blurred vision, blindness, coma, and death. A person may get better but then worse again up to 30 hours later.
Ingestion: Toxic. Symptoms parallel inhalation. Can intoxicate and cause blindness.
Usual fatal dose: 100-125 milliliters.
Skin Contact: Methyl Alcohol is a defatting agent and may cause skin to become dry and cracked. Skin absorption can occur; symptoms may parallel inhalation exposure.
Eye Contact: Irritant. Continued exposure may cause eye lesions.
Chronic Exposure: Marked impairment of vision has been reported. Repeated or prolonged exposure may cause skin irritation.
Aggravation of pre-existing conditions: Persons with pre-existing skin disorders or eye problems or impaired liver or kidney function may be more susceptible to the effects of the substance.
Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention immediately.
Ingestion: Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious person. Get medical attention immediately.
Skin Contact: Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes before reuse.
Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.

Fire: Flash Point: 12c (54f) cc
Autoignition Temperature: 464c (867f) flammable limits in air
% by Volume: lel: 6.0; Uel: 36 flammable liquid and vapor!
Explosion: above flash point, vapor-air mixtures are explosive within flammable limits noted above. Moderate explosion hazard and dangerous fire hazard when exposed to heat, sparks or flames. Sensitive to static discharge.
Fire Extinguishing Media: use Alcohol foam, dry chemical or carbon diOxide. (Water may be ineffective.)
Special Information: in the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode. Use water spray to blanket fire, cool fire exposed containers, and to flush non-ignited spills or vapors away from fire. Vapors can flow along surfaces to distant ignition source and flash back.
Ventilate area of leak or spill. Remove all sources of ignition. Wear appropriate personal protective equipment as specified in 8. Isolate hazard area. Keep unnecessary and unprotected personnel from entering. Contain and recover liquid when possible. Use non-sparking tools and equipment. Collect liquid in an appropriate container or absorb with an inert material (e.g., Vermiculite, dry sand, earth), and place in a chemical waste container. Do not use combustible materials, such as saw dust. Do not flush to sewer! If a leak or spill has not ignited, use water spray to disperse the vapors, to protect personnel attempting to stop leak, and to flush spills away from exposures. US regulations (CERCLA) require reporting spills and releases to soil, water and air in excess of reportable quantities. The toll free number for the us coast guard national response center is (800) 424-8802.
Protect against physical damage. Store in a cool, dry well-ventilated location, away from any area where the fire hazard may be acute. Outside or detached storage is preferred. Separate from incompatibles. Containers should be bonded and grounded for transfers to avoid static sparks. Storage and use areas should be no smoking areas. Use non-sparking type tools and equipment, including explosion proof ventilation. Containers of this material may be hazardous when empty since they retain product residues (vapors, liquid); observe all warnings and precautions listed for the product. Do not attempt to clean empty containers since residue is difficult to remove. Do not pressurize, cut, weld, braze, solder, drill, grind or expose such containers to heat, sparks, flame, static electricity or other sources of ignition: they may explode and cause injury or death.
Airborne Exposure Limits:
- for Methyl Alcohol: - OSHA permissible exposure limit (pel): 200 ppm (twa)
- ACGIH threshold limit value (TLV): 200 ppm (twa), 250 ppm (stel) skin
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures below the airborne exposure limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, industrial ventilation, a manual of recommended practices, most recent edition, for details. Use explosion-proof equipment.
Personal Respirators (NIOSH approved): if the exposure limit is exceeded, wear a supplied air, full-facepiece respirator, airlined hood, or full-facepiece self-contained breathing apparatus. This substance has poor warning properties.
Skin Protection: rubber or neoprene gloves and additional protection including impervious boots, apron, or coveralls, as needed in areas of unusual exposure.
Eye Protection: use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.
Appearance: clear, colorless liquid.
Odor: characteristic odor.
Solubility: miscible in water.
Specific Gravity: 0.8 pH: No information found.
% Volatiles by volume @ 21c (70f): 100
Boiling Point: 64.5C (147f)
Melting Point: -98c (-144f)
Vapor Density (air=1): 1.1
Vapor Pressure (mm hg): 97 @ 20c (68f)
Evaporation Rate (buac=1): 5.9

Hazardous Decomposition Products: May form carbon diOxide, carbon monOxide, and formaldehyde when heated to decomposition. Hazardous Polymerization: will not occur.
Incompatibilities: Strong oxidizing agents such as nitrates, perchlorates or Sulfuric acid. Will attack some forms of plastics, rubber, and coatings. May react with metallic aluminum and generate hydrogen gas.
Conditions to Avoid: Heat, flames, ignition sources and incompatibles.
