Health Hazard Evaluation Report HETA 83-014-1343, North Clackamas School District No. 12, Milwaukie, Oregon

摘要

To determine if symptoms of headache, fatigue and mood changes experienced by the three workers in the phototypesetting room were a result of occupational exposures, environmental air samples were collected to determine exposures to the phototypesetting chemicals. In addition, temperature, relative humidity, and carbon dioxide concentrations were monitored. NIOSH investigators determined that the adverse health effects experienced by the workers in the phototypesetting could be a result of a lack of any air being supplied to the room resulting in an increase of temperature and carbon dioxide levels; low concentrations of acetic acid vapors; glare on the VDT screen; and nonadjustable viewing angle of the screen.
