How do you prove a chemical safe?

  You test it for various common and uncommon cases. Like how does it influence fruit fly fertility if the concentration is above x%. But nothing is 100% sure in the real world, if that was your point, but for practical matters we can get close enough, if we want to. But I know that quite some tests are not being done, because the results would not be welcome.

  There is no ethical way to do control tests on humans. Proof is not in the realm of biology, risk management is.

    Humans don't seem to mind considering how many people buy these jackets either way. I'm sure enough volunteers could be found.
