Gasoline is a skin irratant but not a major one. I have been splashed with gasoline on many parts of my body over the years (that's what happens when you start playing with motorcycles and such at 12 years old). In sensitive areas, it feels like it's burning the skin. But it really isn't causing much damage. There are carcinogens in many solvents, and gasoline is a solvent, as well as a fuel. So it's wise from that standpoint as well, to keep gas off of your skin.
The main danger from gasoline is that it is highly flamable. I know this from personal experience and have the scars on my right shin to prove it. So any time gas is splashed onto your clothing or skin, wash it immediately with fresh and soapy water. Soap is an imulsifier that will help remove the gasoline. Washing with freshwater, baking soda, and salt will help remove the odor, but not completely.
I cannot stress how dangerous it is to have gasoline on the skin or on clothing. It ignites very easily and takes literally seconds to create deep 2nd-degree, or even 3rd degree burns. And I can tell you that I would compare severe burn pain with labor for intensity. And it hurts for much longer that does a bad sprain, or labor. It easily took 8 months for the pain to diminish. And that skin, 24 years later, if I but bump that shin against something, it will break and I have a sore that has to heal.
Be extrememly carefull with flamable liquids. And dispite what is taught us to put out a fire (stop-drop-&-roll), a flamable liquid fire must be completely smothered and removed from all ignition sources to be extinguished. I put my burning pants out after the stop-drop-& roll did nothing, by removing the blue jeans, turning them inside-out as I did so. That put out the fire. Oh, and I had to get about twenty yards further away from the bon-fire that had caused the gas to flash in the first place. As I was running to put distance between me and the fire, my wife was screaming that I was doing the wrong thing. But the gas was just re-flashing as fast as I had been puting it out until I got away from the bon-fire. I was about 30 feet from that fire when my pants initially burst into flame.
If there's gas on you, get it off! Even if in a public place (thankfully, I was out in the boonies) get that clothing off as soon as possible. Don't go through the months of agony that I went through.
And ladies, if you want an education, take a small sheet of metal (like a cookie sheet) and place onto a fire-safe area. Hang a nylon stocking above it and light the stocking with a long butane lighter. Do not let any part of your body get close to the burning nylon! Watch as the nylon melts and drips onto the metal. Nylon, rayon, and other clothing materials made from similar plastics burn easily. And when they do, they melt and stick to your skin, causing severe burns. I have a scar on one of my fingers from a piece of burning nylon rope that dripped onto it. I was fusing the end of a rope with flame, to keep it from unraveling. It's a great way to insure that the rope remains useful. But if you get just a bit careless, you pay a painful price.
