HOMEMADE mixtures of dilute hypochlorite solution with other acidic household chemicals may liberate substantial amounts of chlorine gas. In our experience, the most common domestic combination is a mixture of bleach with lavatory cleaners, usually hydrochloric acid. The growing incidence of mixing household cleaning agents has been noted previously.1 The purpose of this report is to draw attention to a possible hazard of such practice. We describe two cases of pneumomediastinum with subcutaneous emphysema following inhalation of chlorine gas liberated from a mixture of 5% sodium hypochlorite with 10% hydrochloric acid.
