Exposures to formaldehyde (50000), excessive humidity, and dust containing fibrous glass were investigated on July 7 and 8, 1981, September 22, 1981, and February 24, 1982 at the Student Learning Center, Pennsylvania State University (SIC-8221), DuBois, Pennsylvania. The University industrial hygienist requested the evaluation for an unspecified number of employees who reported eye and respiratory irritation, nose bleeds, skin rashes, headaches, and nausea. Area air and bulk samples were analyzed, relative humidity and ventilation were measured, and 12 employees were interviewed. Airborne formaldehyde and dust concentrations ranged from 0.01 to meter (mg/m3), respectively; corresponding NIOSH standards are Lowest Feasible Limit and 5mg/m3. Humidity ranged from 60 to 74 percent. No formaldehyde was found in bulk samples. Nine employees reported that symptoms disappeared after leaving work. After the air conditioning system was readjusted and balanced, eight of the nine workers reported no symptoms. Repeated airborne formaldehyde sampling indicated no measurable contamination. The authors conclude that the workers' symptoms were not related to formaldehyde or dust exposures. They recommend regular balancing of the air conditioning system, and routine health surveillance.
