We rely on a precious layer of ozone to protect us from deadly solar radiation. Because some of the liquids used in refrigeration and cooling are potentially harmful to the ozone layer. Section 608 of the US Federal Clean Air Act requires all persons who work with regulated refrigerants to be certified.
