The flash point is not the ignition point. For exampe the flash point of gasoline is about -40F while its ignition point is about 850F. Yes, it is more hazardous when the liquid temperature exceeds the flash point, but you still need a temperature source at or above the ignition temperature to cause the explosion or fire.
