Don't know where you learned chemistry, but alcohol vapors are generally denser than air.

Also, water in insufficient quantity can spread alcohol fires instead of putting them out... which is one reason alcohol stoves caused some many boat fires... the person would pour water on the fire and the burning alcohol would get washed down into areas of the boat where it wasn't readily visible. By the time they realized their mistake, it was usually way too late. Water is NOT A RECOMMENDED EXTINGUISHING MEDIA FOR ALCOHOL FIRES.

Might want to learn a bit more about alcohol and alcohol fires before opening your mouth. Read the MSDS for denatured alcohol.

Let me quote the relevant section for you:

Alcohol foam, CO2 or dry chemical.

Wear self-contained breathing apparatus approved by the U.S. Bureau of Mines. Use water to cool neighboring containers.[

Flammable. Dangerous fire risk. Toxic by ingestion and inhalation. Vapors are heavier than air and will travel along ground to ignition source.
Finally, alcohol vapors are harder to detect than propane, which is spiked with mercaptan to make it very noticeable due to the odor of the mercaptan.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
