Is chlorine dangerous, unsafe or unhealthy?
Chlorine can certainly be a caustic & dangerous chemical to work with, with some forms being more dangerous for the user and the environment than others. At levels found in spa water, chlorine poses no danger to swimmers or pets. Allergic reactions to chlorine are rare. However some people may experience skin irritation. Additionally, chloramines (common in poorly balanced spa water) are typically the cause of occasional red eyes when soaking. Extremely high levels of chlorine in the water could possibly release gases under certain conditions that can cause breathing difficulties.
