Section III - Hazards Identification
Overview: Toxic by inhalation absorption or ingestion. Can not be made nontoxic. Methanol is a cumulative poison and
death has been reported for ingestion of less than 30 milliliters. Causes CNS depression, headache, intoxication,
dilation of the pupils, convulsions nausea, and dizziness. Unconsciousness and death may result. Methanol
intoxication may produce visual disturbances and blindness.
Safety Ratings
Health: Hazardous Flammability: Flammable Reactivity: Slight Contact: Slight
Recommended safety equipment: safety goggles, lab coat and proper gloves
Storage: Room Temperature away from sources of ignition.
NFPA Ratings
Health = 2 Flammability = 4 Reactivity = 1
Potential Health Effects
The toxicology of this compound have not been completely examined. It is presumed that the toxicity of this item is
similar to other aliphatic alcohols.
Inhalation: Alcohols are absorbed through the mucous membranes and will produce irritation as well as the same
effects as ingestion.
Ingestion: Inhalation will produce CNS disturbance, dizziness, photophobia, headache, stupor, coma and death.
Skin contact: Alcohols are absorbed through the skin. Repeated contact causes defatting of the skin with resultant
irritation and flaking.
Eye contact: May be irritating
Chronic Exposure: Unknown
Aggravation of preexisting conditions: Impaired kidney and liver function may be aggravated by exposure to alcohols.
Preexisting eye, skin, and respiratory conditions may also be aggravated. Methanol has shown genetic toxicity in some
animals.

Section IV - First Aid Measures
Inhalation: Remove from source of exposure and get medical attention for any breathing difficulty.
Ingestion: Do not induce vomiting if patient is unconscious or extremely drowsy. Otherwise administer 2 glasses of
water and induce vomiting. Get immediate medical attention even if symptoms improve.
Skin Contact: In case of skin contact, remove contaminated clothing and flush with water. Wash affected area with
soap and water. Get medical advice if irritation develops.
Eye Contact: In case of eye contact, flush with water for at least 15 minutes and get medical attention.
Section V - Fire Fighting Measures
Flash point: 16oC (61oF) TCC
Flammable Limits (for ethanol): LEL 3% UEL 19%
Fire: Water is ineffective against alcohol fires but may be used to cool adjacent containers.
Fire Extinguishing Media: Alcohol foam, carbon dioxide or dry chemical.
Special information: Pyrolysis will release toxic carbon monoxide.
Section VI - Accidental Release Measures
Remove all sources of ignition, absorb with a suitable absorbent (such as paper towels) and dispose.
Section VII - Handling and Storage
Store in a closed container, away from open flames or other sources of ignition.
Section VIII - Exposure Control/Personal Protection
Airborne Exposure Limits: See section II
Ventilation System: Usually not required. When required, Refer to the ACGIH document, "Industrial Ventilation, a
Manual of Recommended Practices" for details about ventilation.
Personal Respirator: Usually not required. In case of emergency, or when exposure levels are unknown, use a positive
pressure, full face piece, air supplied respirator.
Skin protection: Protective gloves are not required but recommended as part of good laboratory practice.
Eye Protection: Laboratory safety goggles or similar products are not required but recommended as part of good
laboratory practice.
Section IX - Physical and Chemical Properties
Boiling Point: 190oF (88oC) Density: 0.8 g/ml
Vapor pressure (mm Hg): 98 @ 20oC Evaporation Rate (Ethanol = 1): 1
Vapor Density (air = 1): 1.5 Solubility: Infinitely miscible with water
Appearance and Odor: A clear orange liquid with the Characteristic odor of alcohol.
Section X - Stability and Reactivity
Stability: Freezes only at very low temperature.
Hazardous Decomposition Products: Nothing unusual.
Hazardous polymerization: Will not occur.
Incompatibilities: Oxidixers.
Conditions to avoid: heat, flame and sources of ignition.
Section XI - Toxicological Information
Chronic consumption of ethanol is believed to be linked to liver disease, cancer and birth defects.

Ingredient Known Carcinogenicity? NTP? Anticipated? IARC Category
Ethanol no no no none
Methanol no no no none
Isopropanol no no no 3
orange G no no no 3
phosphotungstic acid no no no none
Section XII - Ecological Information
Environmental Fate: Biodegradable
Environmental Toxicity: None expected
Ethanol evaporates quickly and is not expected to bioaccumulate. The material is removed from the air by dry and
liquid adsorption. The half-life for ethanol in the atmosphere is one to ten days.
Section XIII - Disposal
Local governments may restrict the amounts of alcohol that may be flushed down drain. Insure compliance with all
government regulation
Section XIV - Transportation information
