You're spreading FUD and frankly have no idea what you're talking about. An ethanol vapor explosion will be brief and in most cases (unless you're extremely unlucky) will happen fairly early on in this scenario. The typical case will be a figurative flash in the pan that won't spread. The biggest concern is being burned, particularly your eyes.
Grease fires in comparison were one of the leading causes of house fires in the US the last time I checked. The worst case is getting splattered by burning droplets of oil that instantly scald any exposed skin while continuing to burn for long enough to light your clothing on fire. Personally I try to avoid pan frying on a range (as opposed to a dedicated appliance) and if I do I'm careful to verify the location of my fire blanket before starting.
