Reactive airways dysfunction syndrome (RADS) is a syndrome as a persistent bronchial hyperreactivity with asthmatic dyspnea which occurs after one or more inhalation exposures to a high concentration of irritant gasses, smokes or vapors in subjects who had preciously had no respiratory disease. We report a case of a 34 years old female worker suffering from reactive airways dysfunction syndrome who had been taking charge of guest room cleaning at a condominium. 7 months before, she inhaled high concentration of chlorine gas in confined and poor ventilated working space of bathroom at the condominium. As she was washing a bathroom with a bleaching agent (6 % sodium hypochlorite) without dilution, dyspnea, dizziness, headache, nausea, and coughing developed after work. She still suffer from dyspnea and coughing. All functional tests were normal except for methacholine challenge test which reveals bronchial hyperreactivity. She has some symptoms of dyspnea and coughing when exposed to perfume, cold air, and heavy work.
