In response to a request from Local 774 of the International Union of Electronic, Electrical, Technical, Salaried and Machine Workers, possible exposures to numerous substances and hazardous noise levels were evaluated at the Dubois Chemical Company (SIC-2842), Sharonville, Ohio. The production facility formulates about 400 specialty chemical products for institutional and industrial applications. Personal sampling results included the following: sodium-hydroxide (1310732) dust, from nondetectable to 0.63mg/m3; hydrochloric-acid (7647010), nondetectable to 0.05mg/m3; phosphoric- acid (7664382), nondetectable; methylene-chloride (75092), 6.6 to 380mg/m3; and toluene (108883) 0.6 to 45mg/m3. Full shift noise exposures ranged from 78 to 88 decibels-A (dB-A) with a mean of 82dB- A time weighted average. Noise exposures over the NIOSH recommended exposure limit of 85dB-A existed for 5 workers. The author concludes that a health hazard existed from exposures to methylene- chloride. Individual noise exposures at or in excess of the OSHA permissible exposure limit were possible. The author recommends substituting a less toxic chemical for methylene-chloride and improving ventilation conditions. The use of personal protective equipment should be upgraded and the reuse of gloves stopped. The development of a hearing conservation program is suggested.
