Carbon-monoxide (630080) and carbon-dioxide (124389) concentrations were measured at Salomon Brothers, Incorporated (SIC-6711), New York, New York, in September and October, 1984. The evaluation was requested by the firm's medical department because of complaints of headache and eye, nose, and sinus irritation among employees who worked on the 40th floor, trading center. Ventilation surveys were also performed. Carbon-monoxide concentrations were 3 to 5 parts per million (ppm) and carbon-dioxide concentrations averaged about 1,500ppm. A preliminary ventilation survey in September indicated that the amount of fresh air supplied to the trading floor was less than the 20 cubic feet per minute recommended by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE). After additional ventilation equipment was installed, a second survey found that the outdoor air supplied exceeded the ASHRAE recommendations. Following installation of the supplemental ventilation equipment, the employees' complaints abated. The author concludes that in the preliminary survey, a potential health hazard existed due to an inadequate supply of fresh air. Installation of additional ventilation equipment removed the potential hazard.
