In response to a request from Moore Business Forms (SIC-2752), Angola, Indiana, an evaluation was undertaken of reports of nausea, headaches, throat irritation, eye irritation, and aching joints in the Preliminary department. The company manufactured various forms for many customers. About 40 employees work in the department; activities include design and preparation of photolithographic plates, and plate preparation. Carbon-dioxide (124389) levels were between 450 and 825 parts per million (ppm). Relative humidities ranged from 36 to 50%, and temperatures ranged from 69 to 76 degrees- F. Methylene-chloride (75092) levels ranged from 1.81 to 9.69ppm. NIOSH recommends that levels of this contaminant be reduced as low as possible. The source of the contamination was the extensive use of a type cleaner solvent in a press area. The most prevalent symptoms reported were headache, metallic taste in the mouth, fatigue, nausea and joint pain. The authors conclude that a number of conditions in the Preliminary department may contribute to reported employee symptoms. A potential health hazard existed from exposure to methylene-chloride; an alternative solvent should be substituted. The authors recommend several measures to improve air quality at the site. These include increasing the make up air and humidification, relocating the exhausts and intakes on the roof, maintenance or replacement of an air conditioning unit, and modifications to some of the exhaust hoods.
