Just because chlorine in table salt is edible does not mean chlorine gas is not an historic chemical weapon.

If someone were to start pouring bleach into public toilets the response to people then urinating in them would be dramatic, expensive and illuminating. AND NO, I AM NOT ADVOCATING THAT ANYONE DO THIS, IT WOULD BE DANGEROUS.

I seem to recall that in WWI, a Canadian unit under the first/early chlorine gas attack were able to survive by urinating on handkerchiefs, and then breathing through them.

Guess there's a difference between gas, and liberating the gas from the hyperchlorite.
