Abstract
In response to a request from management at the NuTech Chemical Corporation (SIC-2842) located in Denver, Colorado, an evaluation was made of possible employee exposure to copper-sulfate (7758998), sulfuric-acid (7664939), and acetic-acid (64197) at the facility. The company has recently begun producing odorizing chemicals for sulfuric-acid waste treatment, food and by products operations, set odors, and other uses. A total of 18 air samples, six personal and 12 area, were collected for each of these chemicals. Personal breathing zone and area samples for acetic-acid ranged from 12.6 to 51.3mg/m3, indicating that some exceeded the OSHA Standard of 25mg/m3. Before the employees began using personal protective clothing, they had experienced irritation to the eyes, nose, and throat. Sulfuric-acid and copper-sulfate were not detected. The author recommends that a local exhaust ventilation system be installed in the chemical mixing location. An eyewash station and safety shower should be made immediately accessible to workers. Preplacement and periodic medical examinations should be instituted giving particular attention to skin, eyes, teeth, and respiratory tract problems and including pulmonary function tests.
