I don't think "chlorine gas" but rather chloramine. In pools when chlorine binds to contaminates, it forms chloramine, which is a gas that sits on the surface of the pool.
I was thinking that seems more plausible. Especially where pool patrons have bad pool etiquette. I didn't want to steer the conversation in the event I got it wrong.
