Abstract
Background A cluster of biopsy-confirmed interstitial lung disease among wo rkers at a nylon flock plant led to a request for National Institute for Oc cupational Safety and Health investigators to conduct a health hazard evalu ation. Methods Part of the overall evaluation, reported here, involved a cross-sec tional medical survey of current employees. The survey consisted of a quest ionnaire, spirometry and diffusing capacity testing, and chest radiograph. Results Workers assigned to production and maintenance jobs reported freque nt eye and throat irritation, respiratory symptoms, and systemic symptoms ( i.e., generalized aches and fevers). Most reported improvement when away fr om work. Frequent respiratory/systemic symptom prevalence was significantly associated with departmental category, with days and hours worked per week , and with working on a flocking range. Compared to asymptomatic workers, s ymptomatic workers had similar mean ratios of forced expiratory volume in o ne second to forced vital capacity, but lower mean percent of predicted val ues for both forced vital capacity and diffusing capacity. All acceptable c hest radiographs were classified as category 0 for small opacities, Conclusions Findings of this study, along with those from studies reported elsewhere, implicate occupational exposure to flock-associated dust as a si gnificant respiratory health hazard at this plant.
