NIOSH 1992 Aug; :1-22
In response to a request from an employee of the Veterans Administration Medical Center (SIC-8062), Los Angeles, California, an investigation was undertaken of exposures to chemicals in the laboratory department, excessive heat and humidity in the kitchen area of the dietetics department, and carbon-monoxide (630080) exposures inside the building. In three of five personal breathing zone samples taken in the histopathology laboratory, formaldehyde (50000) was detected at concentrations up to 0.17 part per million (ppm) and it was also present in all four of the area air samples at concentrations up to 1.1ppm. The predominant symptoms associated with work in the laboratory included occasional headaches and nose/throat irritation. Mild episodes of dermal irritation and rash were also reported. All carbon-monoxide levels were less than 5ppm. In the kitchens, relative humidity levels were below the recommended range. Temperatures were above the range of temperatures recommended for a medium level of work. The authors conclude that a potential carcinogenic risk existed for workers in laboratories which use formaldehyde. The authors recommend specific measures to lower the risk of formaldehyde exposures in this laboratory.
