In response to a request from the management of Eagle Convex Glass Company (SIC-3231), Clarksburg, West Virginia, an evaluation was made of possible worker exposure to hazardous conditions resulting in occupational pneumoconiosis, hearing loss, and cumulative trauma disorders. The company produced a wide variety of speciality glass products for the automotive, furniture, and major appliance industries, employing 171 workers over three shifts. Hydrofluoric- acid (7664393) concentrations ranging from 0.34 to 3.0mg/m3 were measured in the etching department. Analysis of the two solvents used in the decorating department indicated one contained mostly C10 to C11 alkyl substituted benzenes plus naphthalene (91203). The following compounds were also identified: trimethylbenzene (95636), methyl-ethyl-benzene (98828), and indan (496117). Noise levels in excess of the NIOSH Recommended Exposure Level of 85 decibels-A, as a time weighted average, were found in some departments. Respirable dust levels ranged from 0.08 to 0.20mg/m3. Symptoms consistent with hand/wrist, shoulder, and neck cumulative trauma disorders were noted among 20 to 30 percent of the workers in the decorating, processing, mirror and polishing departments. The authors conclude that some workers were potentially exposed to cumulative trauma, acid mists, and noise. The authors recommend specific measures, including work practices, ergonomic changes, a hearing conservation program, and a respiratory protection program.
