In response to a request from the president of the General Staff Association of the New Jersey Education Association (NJEA) (SIC- 9451) an evaluation was made of the NJEA building in Trenton, New Jersey due to reports of headache, sore throat, and eye irritation among employees. Air monitoring tests were conducted for formaldehyde (50000) carbon-dioxide (124389), carbon-monoxide, (630080), dry bulb temperature, wet bulb temperature, humidity and air velocity at air inlet and exhaust diffusers. Very little to no air movement was detected at employee work locations. Inside the building the carbon-dioxide concentrations were two to four times those outside the building. Controls used to operate dampers and supply outdoor air in some cases appeared faulty and needed inspection and adjustment. Relative humidity was lower than recommended. No detectable levels of formaldehyde or carbon- monoxide were found. Eighty percent of the employees returned completed questionnaires concerning symptoms of health problems. Repeated complaints of dryness of mucous membranes, dryness of eyes, headache, and tiredness were noted. The authors recommend that the air velocity be increased to 30 to 35 feet/minute in the work areas of the building. Other recommended improvements include relocation of the outdoor exhaust stack, redesign of inlet diffusers to direct the air down further into the work areas, redesign of ventilation systems if needed, and restriction of smoking to specified areas of the building.
