An environmental survey was conducted in the photography laboratory of the Learning Resources Support Services at Cuyahoga Community College (SIC-8222), Cleveland, Ohio on July 10 and 11, 1985 to assess exposures to reagents and byproducts of processes used. The evaluation was requested by District 925, Service Employees International Union for the investigation of worker complaints of dizziness, nausea, headaches and other symptoms they believed were related to photographic developing and printing processes. Air samples were collected for acetic-acid (64197), sulfuric-acid (7664939), ammonia (7664417), formaldehyde (50000), and sulfur- dioxide (7446095); a personal breathing zone sample for acetic-acid and sulfuric-acid was collected on a laboratory worker over a six hour period. The time-weighted average exposure was 0.2 milligram per cubic meter (mg/M3) for acetic-acid (NIOSH Recommended Exposure Limit (REL) of 25mg/M3) and 0.02mg/M3 for sulfuric-acid (REL of 1mg/M3). Short term exposure to ammonia was about 1 part per million (ppm) (REL of 50ppm). The other compounds were not detected in breathing zone samples. The existing ventilation system was evaluated. The author concludes that workers were not overexposed to substances used in photographic developing and printing. Inadequate fresh outside air was being supplied and local exhaust ventilation was not effective. Recommendations are made regarding general work room air quality and work practices for the laboratory.
