Case Study: Evaluation of Chlorine Gas Detection from Bleach Products Using an AccuSafe Monitoring System

Household bleach, containing approximately 5–6% sodium hypochlorite, is widely used as a disinfectant and cleaning agent. When applied to surfaces, bleach releases a mixture of volatile compounds, including water vapor, hypochlorous acid (HOCl), and, under certain conditions, chlorine gas (Cl2). While the alkaline pH of commercial bleach typically limits Cl2 outgassing, the presence of acid, ammonia, or organic contaminants can substantially increase Cl2 vapor release.
