The msds sheets were written to apply to handing commercial size containers, like a 45 gallon barrel of the stuff, not to qtys you will be handling. Try reading the msds sheets for the ingredients of the gasoline you put in the tank of your vehicle. You probably wouldn't want to go within a hundred yards/meters of a filling station if you took those ones seriously, much less drive around with 15 gallons of it in the car.
reminds me of watching my dad working on the farmall H tractor. He'd take the fuel filter glass bowl off and suck out whatever was in there. That usually resulted in a fair amount of gas (leaded) in his mouth, which he'd spit out rather quickly.
