The OSHA permissible exposure limit (PEL) for benzene is 1 part per million (ppm) as an 8-hour time-weighted average (TWA), with a short-term exposure limit (STEL) of 5 ppm for any 15-minute period.
The benzene content limit in gasoline in the United States is set at 0.62% by volume, with a maximum average standard of 1.3% that took effect in 2012.
Are you swimming in your fuel?
It was a freak petrol fight accident...
Never got a drip on you filling up? There's 10,000x as much benzene in gas as OSHA alllows for expoure
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.
