Abstract Employees of a communications firm experienced an acute outbreak of nonspecific illness related to the workplace. Symptoms consisted primarily of coughing, throat irritation, shortness of breath and disorientation. Fifty-one individuals sought emergency medical care, and the building was evacuated. A multidisciplinary team was assembled to investigate and resolve the problem. Investigation activities focused on three major areas: epidemiology; environmental measurement; and mechanical engineering. Results indicated that the outbreak was due to multiple factors working in concert. The inside of the air handling system was contaminated with microbial growth and particulate matter; chemical products were used throughout the building with little control over use patterns; and the HVAC system was not delivering acceptable quantities of outdoor air to the employees’ breathing zones. Two unusual events may have triggered the employees’ response. An unusual odor/taste was reported, and the outside air damper abruptly opened and closed, possibly dislodging particulate matter from inside the air handling system. It appeared that psychosocial factors played an important role. Prevention of similar crises could be achieved by implementation of a policy/procedure that addresses specific responsibilities, communications, preventive maintenance, acceptable outdoor air ventilation rates, and guidelines for reporting and investigation.
