Chlorine and chloramine gas are frequently produced in the home when cleaning products are mixed. These gases are strong irritants with the potential for tissue damage. Numerous literature citations report industrial exposures to chlorine/amine gas, but there are few reports regarding home exposures. The purpose of this study was to determine symptoms, treatment, and outcome in individuals exposed to these gases in the home. All exposures to chlorine/amine gas produced as a result of mixing cleaning products in the home and reported to a Regional Poison Information Center (RPIC) over a 12-month period were reviewed. All calls were documented and follow-up was done at appropriate intervals. All patients with respiratory embarrassment either at the initial contact or on follow-up were referred to a medical facility. Of the 216 patients (ages 12 to 81 years), 200 had resolution of symptoms within 6 hours, whereas only 16 had symptoms for more than 6 hours after exposure; 145 patients were treated at home and 71 received further medical care. Ten symptoms were identified, with the majority of patients experiencing more than one. Emergency room treatment included oxygen (62 patients), bronchodilators (9 patients), and steroid therapy (3 patients). Of the 70 patients who had chest x-ray films, only one had a positive finding; 41 had arterial blood gas measurements done, and all were within normal limits. Only one patient in the study group required admission for continued respiratory distress, but he had a preexisting chronic respiratory problem as well as an upper respiratory tract infection at the time of exposure. Although the gas produced by mixing cleaning products in the home can cause severe respiratory irritation, most of the patients exposed to chlorine and chloramine gas can safely be treated at home with comfort measures. Appropriate follow-up must be done to determine resolution of symptoms.
