Description:In response to a request from the management of the Arcade Parking Garage (SIC-7525), in Providence, Rhode Island, a determination was made of possible hazardous health conditions at the garage due to the presence of carbon-monoxide (630080) fumes. The garage had nine parking levels, eight above ground. The building was constructed of reinforced poured concrete and the above ground parking spaces were open to the outside, allowing the free circulation of air. Environmental monitoring consisted of carbon-monoxide and carbon- dioxide (124389) air sampling in a collection booth and in the office. The results of the short- and long-term air sampling indicated exposure to carbon-monoxide ranging from 17 to 103 parts per million (ppm). Carbon-dioxide levels were measured at greater than 1000ppm in the office area, indicating inadequate ventilation. The carbon-dioxide levels were all well below the industrial standard of 5000ppm but were above the 1000ppm indoor air quality guideline. Measurements for thermal comfort indicated temperatures were between 62 and 65 degrees-F, with relative humidities ranging from 28.3 to 43.7 percent. These thermal comfort values were within the guidelines for human occupancy. The reported symptoms of the employees were consistent with carbon-monoxide exposure. The author concludes that a potential health hazard existed due to carbon- monoxide. The author recommends measures to minimize employee exposures.
