NIOSH 1981 May:6 pages
Environmental air samples were analyzed for formaldehyde (50000) and medical interviews were conducted at the Tri Valley Federal Credit Union (SIC-6142) in East Helena, Montana on March 10, 1981. An unidentified individual requested the evaluation on behalf of the four employees, all of whom reported respiratory symptoms and burning of the eyes. All air samples for formaldehyde were below the laboratory limit of detection of 8 micrograms per sample. Trace quantities less than 0.1 part per million (ppm) were detected using direct reading tubes. The NIOSH permissible exposure limit for formaldehyde is 1 ppm. The authors conclude that the reported symptoms were probably caused by exposure to trace quantities of formaldehyde and that workers may have become sensitized to formaldehyde when the building was originally insulated with urea formaldehyde foam. They recommended that the employees be informed of the potential hazards of formaldehyde exposure, and that employees only smoke in a designated, well ventilated area.
