I just had a concrete floor cut for plumbing, and neither of the guys wore a mask or respirator which is insanely unhealthy. I have a feeling it was "not manly".
I worked one summer at the same factory as my dad. One day I was operating a cutting machine and my dad came by because I wasn't wearing any safety equipment. He suggested (not told) to wear the gear but I refused because no one else uses it. He said thats fine, it's my choice but he suggested I walk around the factory floor and count how many workers had all their fingers. I put on the safety equipment. Later on while having lunch with the two other guys in our area I noticed both were missing fingers.
If you're careful you may never need the protection a seat belt provides. It's still foolish and risky to go without it. Table saw guards, etc. are the same.
I don't imagine you have to worry about it. It's more of am issue for them because it was frequent excessive lengthy exposures. It wasn't helped by the fact that they didn't wash their hands a lot.
Occasional exposure isn't going to do much. Some people even use kerosene (diesel) can be used to wash some things off your hands. But you want to avoid it when possible.
Another reason I hate the EPA "safety" gas can nozzles. Because I've never felt more safe than when I'm covered in gasoline.
Generally, I'm all for things that limit emissions and improve safety. I always thought they were a PITA, but couldn't really be that much worse than the ones I see people use at the track usually.
I finally picked one up because it was all they had at the store, and holy shit those "safety tanks" are a nightmare by comparison. They spill so much fuel and after only a couple of years the seals on mine have gone bad and leak even more. I still would like to add a flame arrestor into the necks, but it amazes me at how awful they are.
I wholly understand why they exist and what all the safety features are for (preventing fuel from spilling if they're tipped/dropped, releasing fuel vapors, etc) but they seem utterly useless when I inevitably spill at least half a cup of fuel per 5 gal, just due to how poorly they're made.
Fuels are mostly hydrocarbons and those are hydrophobic and lipophilic. i.e they dissolve greasy/fatty things and your skin contains oils (which the fuel dissolves and thus strips out) and your cells are basically bags of water where the bag part (cell membrane) is made up of phospholipids (basically a type of fat) so that gets degraded too. None of that is good for your skin.
These are typically the big right wingers who later in life live in a constant state of rage because they're crippled or disabled and blame the government or immigrants for the fact that they live on a $1200/mo disability check, can't work, and have nothing to their name. At least that's my personal experience.
