Gasoline can be ignited by even a tiny spark at temperatures as low as fifty below zero, but it merely evaporates at temperatures up to about four hundred seventy five to five hundred F. At that temperature, it ignites spontaneously.
Auto-Ignition Temperature: The lowest known value is 363Â°C (685.4Â°F) (Ethyl alcohol 200 Proof). Flash Points: CLOSED CUP: Between -18Â°C (0Â°F) and 23Â°C (73Â°F). Flammable Limits: The greatest known range is LOWER: 6% UPPER: 36.5% (Methyl alcohol) Products of Combustion: These products are carbon oxides (CO, CO2). Fire Hazards in Presence of Various Substances: Highly flammable in presence of open flames and sparks, of shocks, of heat.
