HHE report no. HETA-91-176-2168, Garfield County Courthouse, Glenwood Springs, Colorado.
NIOSH 1991 Dec; :1-17
In response to a request from the Administrator of Garfield County, Colorado, a study was undertaken of possible hazardous working conditions at the County Courthouse (SIC-9222). Employees at the building had complained of itchy watery eyes, stuffy and/or runny nose, headaches, sore throats, and other problems since the building had been expanded in 1984. The building was four stories and the heating, ventilation and air conditioning system consisted of a central variable air volume system with hot water reheat on the exterior terminal units. Cooling was provided by an indirect chilled water coil and a direct evaporative cooling section. Temperature ranged from 71 to 76 degrees-F and humidity from 36 to 42%. Carbon-monoxide (630080) levels were less than 2 parts per million. Air samples for aldehydes were all below the limits of quantitation. Air samples for dusts resulted in only low levels of common, low toxicity materials. The author concludes that no airborne contaminant was identified which could constitute a health hazard. The author recommends measures to help alleviate the employee complaints.
