First-Aid Measures

Eyes
Rinse with plenty of water for at least 15 minutes. Remove contact lenses if present and easy to do. Continue rinsing. Seek medical attention immediately.
Skin
Immediately flush with plenty of water for at least 15 minutes while removing contaminated clothing. Wash with soap. Get medical attention immediately.
Inhalation
Move person to fresh air and keep comfortable for breathing. If breathing is difficult, give oxygen. If not breathing, give artificial respiration. Get medical attention immediately.
Ingestion
Do Not Induce Vomiting! Never give anything by mouth to an unconscious person. If conscious, wash out mouth with water. Get medical attention immediately.
Most Important Symptoms and Effects
  • Eye contact causes irritation: redness, pain and tearing.
  • A single exposure may damage organs.
Immediate Medical Attention and Special Treatment
  • Treat symptomatically. Get medical attention if symptoms develop or persist.
Section 5

Fire-Fighting Measures

Suitable Extinguishing Media
Alcohol-resistant foam, CO2, dry chemical powder. Water spray may be used to cool fire-exposed containers.
Unsuitable Extinguishing Media
Do not use a solid water stream — may scatter and spread fire.
Specific Hazards Arising from the Chemical
Vapors are heavier than air and may form explosive mixtures with air; they can travel to a source of ignition and flash back. Containers may rupture when heated.
Protective Equipment
Wear self-contained breathing apparatus and full protective clothing.
Hazardous Combustion Products
Carbon monoxide and carbon dioxide on combustion; formaldehyde from incomplete combustion of methanol.
Section 6

Accidental Release Measures

Personal Precautions
Use PPE as described in Section 8. Ensure adequate ventilation. Evacuate personnel to safe areas.
Hazard-Specific Precautions
Eliminate all ignition sources. Use non-sparking tools and explosion-proof equipment; ground and bond containers during cleanup.
Environmental Precautions
Prevent leakage or spillage from entering drains, sewers, or waterways.
Containment & Cleanup
Absorb with inert material. Collect in appropriate waste container. Dispose per applicable regulations.
Section 7

Handling and Storage

Safe Handling
Use with adequate ventilation. Avoid contact with skin, eyes, and clothing. Wash thoroughly after handling. Keep container closed when not in use.
Safe Storage
Store in a cool, dry, well-ventilated area away from heat, sparks, and open flame. Keep away from incompatible materials (see Section 10). Keep containers tightly closed. Ground and bond containers when transferring material.
Specific Storage Precautions
Keep containers tightly closed in a cool, dry, well-ventilated flammables area away from heat, sparks, open flame and direct sunlight. Keep in fireproof surroundings separated from strong oxidizers. Do not store above 49 °C (120 °F). Ground and bond containers when transferring.

Toxicological Information

See below for route-specific acute toxicity data.

Likely Routes of Exposure
Inhalation, skin contact, eye contact, ingestion.
Symptoms
  • Eye contact causes irritation: redness, pain and tearing.
  • A single exposure may damage organs.
Delayed and Chronic Effects
  • No delayed or chronic effects identified beyond the classification in Section 2.
Acute toxicity
RouteValue
LD50 Oral (rat)Ethanol 7,060–10,470 mg/kg (rat); methanol 5,600–6,200 mg/kg (rat), but humans are far more sensitive — methanol causes blindness and death at much lower doses. ATE for the mixture about 2,100 mg/kg (methanol 100 mg/kg acute-toxicity estimate).
LD50 Dermal (rabbit)Ethanol > 2,000 mg/kg; methanol ATE 300 mg/kg (ATE for the mixture > 6,000 mg/kg)
LC50 Inhalation (rat, 4h)Ethanol 124.7 mg/L (vapor); methanol ATE 3 mg/L (ATE for the mixture > 20 mg/L)

Carcinogen Classification

Carcinogen classification
AgencyStatus
IARCGroup 1 — carcinogenic to humans (Ethanol; IARC agent: Ethanol in alcoholic beverages, Vol. 96, 100E).
NTPKnown to be a human carcinogen (Ethanol; NTP listing: Alcoholic Beverage Consumption).

Persistence & Degradability
Not persistent; rapid aerobic biodegradation — Readily biodegradable (89% ThBOD in 2 wk, activated sludge)
Bioaccumulative Potential

Mobility in Soil
Very high soil mobility (log Koc 0.20)
Section 13

Disposal Considerations

Dispose of contents/container in accordance with applicable federal, state, and local regulations. Do not dispose of into drains or waterways.

EPA RCRA Waste Codes
D001 (ignitable). Not U154: methanol is a denaturant, not the sole active ingredient.

If discarded, this material may be an ignitable hazardous waste (EPA RCRA D001, 40 CFR 261.21(a)(1): flash point below 60 °C; aqueous solutions with less than 24% alcohol by volume are excluded). The waste generator must make the final hazardous-waste determination.
