HHE Report No. HETA-80-148-1025, Mountain Bell, Denver, Colorado.
Environmental and personal air samples were analyzed for sodium- hydroxide (1310732), ethyl-alcohol (64175), triethylamine (121448), hexane (110543), and hydroquinone (123319) at Mountain Bell (SIC- 481) in Denver, Colorado on June 19 to 20, 1980, and on September 2 to 3, 1981. An unidentified individual requested the evaluation on behalf of an unspecified number of workers. Sodium-hydroxide, ethyl- alcohol, triethylamine, hexane, and hydroquinone were all well below their respective NIOSH and OSHA standards of 2, 1900, 100, 360, and 2 milligrams per cubic meter of air. Medical interviews revealed that Graphics clerks experienced some adverse health effects including eye, nose and throat irritation, chest tightness, and dermatitis. The author concludes that all chemical exposures were below applicable criteria, although exposures to hazardous chemicals may have existed in the past. The author suggests the provision of adequate dilution ventilation, use of appropriate personal protective equipment, and worker education.
