During WW1 he was used in chemical warfare to kill other troops by getting in there lungs. He has switched to a better life now with no killing and became a super hero.

Captain chlorine now goes out at night so no one breaths him in and kill them. He goes from house to house and jumps in their pool. He helps clean pools and acts as an antiseptic. He also puts a small amount of himself in their water to clean it and make it drinkable. And if there is a real need for it or a big criminal he will use his Chlorine gas and combine with water in your airways to form hydrochloric acid, which is a potent respiratory irritant and causes swelling of the airways. And kills the criminal and keeps us safe he is the best superhero!
