PSA: 20.23000XLogP3: -0.39150
Appearance:
Methanol appears as a colorless fairly volatile liquid with a faintly sweet pungent odor like that of ethyl alcohol. Completely mixes with water.
The vapors are slightly heavier than air and may travel some distance to a source of ignition and flash back.
Any accumulation of vapors in confined spaces, such as buildings or sewers, may explode if ignited.
Used to make chemicals, to remove water from automotive and aviation fuels, as a solvent for paints and plastics, and as an ingredient in a wide variety of products.

Precautions for safe handling
NO open flames, NO sparks and NO smoking.
NO contact with incompatible substances.
Closed system, ventilation, explosion-proof electrical equipment and lighting.
Do NOT use compressed air for filling, discharging, or handling.
Use non-sparking handtools.
Handling in a well ventilated place.
Wear suitable protective clothing.
Avoid contact with skin and eyes.
Avoid formation of dust and aerosols.
Use non-sparking tools.
Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Fireproof. Separated from strong oxidants and food and feedstuffs. Cool.When large amounts of methanol are stored in enclosed 14 Methanol spaces, monitoring by means of lower explosion limit monitors is desirable.
