Those OSHA guidelines are for gaseous phase. Which yes you’re likely to get a high concentration even just pumping gas, but my guess is it averages out to within the limits. Seems weird to state liquid fractions.
It’s because Benzene is so volatile that it will rapidly evaporate and then it’s density is low enough that it spreads out so quickly that in a very short time it’s no longer dangerous. You basically have to crouch down and huff by the fuel nozzle or be pumping gas in a small enclosed space for any significant health impacts.
