Methanol Vehicles:
Will methanol mix with water?
Yes
Methanol Vehicles:
A mixture of methanol and water is still flammable when diluted with approximately ___ parts water to 1 part methanol.
5 parts
Methanol Vehicles:
Evaporation of methanol at ordinary room temperatures creates a potentially explosive methanol-air mixture when the methanol content reaches ___ % volume.
6%
Methanol Vehicles:
A fire hazard exists if the storage temperature of methanol in contact with air approaches the flash point of ___°F
52°F
Methanol Vehicles:
A methanol-water mixture is still a flammable liquid by OSHA definition (flash point 100°F) with as little as ___% methanol by volume
21% by volume or;
25 percent by weight
Methanol Vehicles:
Methanol burns with ____ (high/low?) flame luminosity
Low
Methanol Vehicles:
The reason methanol fires are less visible than gasoline or diesel fuel fires is that burning methanol produces no ____
