I believe with some electrode materials it is possible to make chlorine gas, I'm not sure if steel and iron are some of them. But either way, as I understand if, you do it slowly you're _mainly_ going to make bleach instead, with small amounts of chlorine gas. Probably not the best idea to breathe it anyway, but shouldn't take much ventilation to make it perfectly safe.
