higher than the flash point

Explanation: the flash point is the lowest temperature at which a liquid produces enough vapor to form an ignitable mixture with air (requires an external ignition source). The ignition (autoignition) temperature is the temperature at which the vapor will ignite without any external spark or flame, and is therefore higher than the flash point.
